Abstract

As an important cognitive bias, the framing effect shows that our decision preferences are sensitive to the verbal description (i.e., frame) of options. This study focuses on the neural underpinnings of the social framing effect, which is based on decision-making regarding other people. A novel paradigm was used in which participants made a trade-off between economic benefits and the feelings of others. This decision was described as either a “harm” to, or “not helping,” other persons in two conditions (Harm frame vs Help frame). Both human males and females were recruited. Participants behaved more prosocially for Harm frame compared with Help frame, resulting in a significant social framing effect. Using functional magnetic resonance imaging, Experiment 1 showed that the social framing effect was associated with stronger activation in the temporoparietal junction (TPJ), especially its right part. The functional connectivity between the right TPJ (rTPJ) and medial prefrontal cortex predicted the social framing effect on the group level. In Experiment 2, we used transcranial direct current stimulation to modulate the activity of the rTPJ and found that the social framing effect became more prominent under anodal (excitatory) stimulation, while the nonsocial framing effect elicited by the economic gain/loss gambling frame remained unaffected. The rTPJ results might be associated with moral conflicts modulated by the social consequences of an action or different levels of mentalizing with others under different frame conditions, but alternative interpretations are also worth noting. These findings could help elucidate the psychological mechanisms of the social framing effect.

SIGNIFICANCE STATEMENT Previous studies have suggested that the framing effect is generated from an interaction between the amygdala and anterior cingulate cortex. This opinion, however, is based on findings from nonsocial framing tasks. Recent research has highlighted the importance of distinguishing between the social and nonsocial framing effects. The current study focuses on the social framing effect and finds out that the temporoparietal junction and its functional connectivity with the medial prefrontal cortex play a significant role. Additionally, modulating the activity of this region leads to changes in social (but not nonsocial) framing effect. Broadly speaking, these findings help understand the difference in neural mechanisms between social and nonsocial decision-making. Meanwhile, they might be illuminating to promote helping behavior in society.

Introduction

In humans, the preference of different options could change dramatically in response to two objectively, but not verbally, equivalent statements (i.e., “frames”) of an identical problem (Rabin, 1998). This “framing effect” phenomenon deviates from standard economic assumptions (e.g., the axiom of descriptive invariance) and thus has become a hot research topic (Tversky and Kahneman, 1981). Framing research is not a homogeneous endeavor; rather, researchers have proposed various taxonomies (Kühberger, 1998; Levin et al., 1998). Notably, the social framing effect could be distinguished from the nonsocial one according to whether a social dilemma between the self and others is involved in the current scenario. In our opinion, a social framing effect manifests when changing the description of a social dilemma (or a specific social component in this dilemma) significantly modulates a decision-maker's preference to different options. The psychological mechanisms of the nonsocial framing effect and that of the social one are essentially different (Ellingsen et al., 2012). When making nonsocial decisions(e.g., gambling), people focus on maximizing their individual utility, and decision frames affect their judgment of which option is more beneficial or less risky. In contrast, when making social decisions, people take the consequence of their actions to others into account, and decision frames affectpeople's preference through the influence of other-regardingconcerns and social norms, such as fairness, altruism, and reciprocity (Van Dijk and Wilke, 2000). For instance, labeling a task as the “Community Game” rather than the “Wall Street Game” increased participants' cooperation rate (Liberman et al., 2004).

Studies on the neural underpinnings of the framing effect have proliferated in the last decade. To our knowledge, these studies have overwhelmingly focused on nonsocial framing, especially a gain/loss gamble framing task. Using this task, De Martino et al. (2006) first revealed that the amygdala activated more strongly when participant decisions were consistent with the nonsocial framing effect, whereas the anterior cingulate cortex (ACC) activated more strongly when decisions ran counter to this effect (see also Roiser et al., 2009; Guitart-Masip et al., 2010; Xu et al., 2013; Li et al., 2017; Wang et al., 2017). According to De Martino et al. (2006), these neural activity patterns modulated approach/avoidance tendencies on the individual level. The current study is interested in the neural underpinnings of the social framing effect. In our opinion, this effect would recruit specific regions that play important roles in social-cognitive processes and in decision-making (Parkinson and Wheatley, 2015; Tavares et al., 2015). According to the literature, the candidate regions include (but are not limited to) the temporoparietal junction (TPJ), inferior frontal gyrus, posterior cingulate cortex, and superior temporal sulcus (Sanfey, 2007; Rilling and Sanfey, 2011).

With two experiments, this study aimed to redress the paucity of knowledge using a paradigm in which the social implication of an option was emphasized or obscured. Specifically, we asked participants to make a trade-off between economic benefits and the feelings of others; when participants showed stronger preference to income maximization, the probability for their partners to receive a painful electrical shock would increase proportionally. This decision was described as either a “harm” to, or simply “not helping,” other persons in two frame conditions. In this way, we hoped to distinguish between the influence of social processes and the approach/avoidance emotions elicited by economic gains or losses. Considering that avoid harming others is a strong, universal motive among human beings (Crockett et al., 2014), we hypothesized that participants would make more costly helping decisions in the Harm frame compared with the Help frame condition, resulting in a significant social framing effect. In Experiment 1, we explored with functional magnetic resonance imaging (fMRI) whether decisions consistent with the social framing effect would activate specific brain areas. Then in Experiment 2, we examined with transcranial direct current stimulation (tDCS) if temporarily modulating the activity of key regions found in Experiment 1 would lead to changes in the social framing effect.

Experiment 1 (fMRI)

Materials and methods

Participants

Thirty right-handed participants were recruited from Shenzhen University to join in the fMRI experiment. Participants were screened for a history of neurologic disorders, brain injury,and developmental disabilities. All had a normal or corrected-to-normal vision. Three of them who had excessive head movements >2° in rotation or >2 mm in translation during the scanning were excluded, leaving 27 participants in the final sample (13 women, age: 21.0 ± 1.8 years, mean ± SD). The study was conducted according to the ethical guidelines and principles of the Declaration of Helsinki and was approved by the Medical Ethical Committee of Shenzhen University Medical School. Informed consent was obtained from all participants after they fully understood the procedures.

Experimental design and statistical analysis

Upon arrival at the laboratory, each participant was introduced to another participant (who was actually a confederate of the same sex). The two of them drew lots to decide their roles in the formal task, which were manipulated such that the real participant would always play as a “decider” while the confederate would play as a “victim.” The real participant was then led to the fMRI environment; this participant was told that the victim would be in another room and that they would complete the task simultaneously via web connections.

Our paradigm was generally adapted from the “Approach-Avoidance Conflict” task, which has been proven to be suitable for fMRI research (Aupperle et al., 2011, 2015). In addition, the idea of providing a dilemma between subjective cost and physical pain for other people was inspired by Crockett et al. (2014), which pointed out that “an aversion to the suffering of others is a powerful motivator for humans.” Before the scanning day, all participants were asked to submit a digital photograph that was expected to be used if they were assigned to the role of “victim” in the experiment. In reality, no participant would serve the role of “victim,” and their photographs were not used for any purpose. The experiment applied a one-factor (social frames: Help frame vs Harm frame) within-subject design. In each trial, a photograph of the confederate (“victim”) would be presented for 2 s to indicate the beginning of that trial. Then, each participant was shown a runway with pictures and texts on its left and right ends to represent two possible outcomes. In the “Help frame” condition, one outcome was “help the other person to avoid receiving a painful shock and subtract 5 RMB from your own payment,” whereas the other outcome was “do not help the other person to avoid receiving a shock and keep all your payment.” In the “Harm frame” condition, one outcome was “harm the other person by administering a painful shock and keep all your payment,” whereas the other outcome was “do not harm the other person by administering a shock and subtract 5 RMB from your own payment” (Fig. 1A).

Experimental design. A, The “Help” and “Harm” frames. B, Structure of a trial. The target event for fMRI data analysis was the decision phase (red rectangle).

In both frame conditions, each participant essentially faced the same “costly helping” decision. The only difference between the two conditions was how the outcomes were framed. Specifically, the outcome “the participant keeps all money and the victim receives a painful shock” was described as not helping others in the “Help frame” condition but as intentionally harming others in the “Harm frame” condition, whereas the outcome “the participant loses 5 RMB and the victim receives no shock” was described as helping others in the “Help frame” condition but as avoid harming others in the “Harm frame” condition.

Each participant was asked to position an avatar on the runway to indicate his/her relative preference between the two potential outcomes. The final placement of the avatar would determine the occurrence probability of the two possible outcomes. For example, if the avatar was placed at the midpoint of the runway, the probability of each outcome was 50%; if the avatar was placed all the way to one side, the probability of its neighboring outcome was 90% and that of its farside outcome was 10%. The resolution of the slider was 10%, and the outcome position on either side of the slider was counterbalanced across trials. The participants were informed in the task instruction phase that they can influence the probabilities of the two outcomes by moving the avatar; otherwise, if they do not want to influence the outcome probability, then they can leave the avatar to the 50% point. The starting point of the avatar was randomized between trials, and the participants had 4 s to respond (i.e., decision phase). To respond, each participant pressed one of two preassigned buttons on an MRI-compatible button-box to move the avatar and pressed a third button to confirm its final place. After a 2-4 s waiting time, the feedback would be presented for 2 s. The interstimulus intervals were set to 1-11 s (Fig. 1B).

The feedback was generated by the computer according to the probability chosen by each participant, which serves as a reinforcing cue to inform the participants that their decisions were valid. Before the experiment, the participants were instructed that, throughout the task, only the feedback of 10 random trials would be executed. To avoid this feedback from influencing participant decisions in the following trials, they were not informed on which trial the feedback was actually executed. Participants were told that they would be informed about the outcomes of the executed trials after the scanning phase. These 10 trials would be randomly selected by the computer; thus, the best strategy for each participant was to treat each trial equally.

The experiment consisted of two runs of 40 trials lasting ∼30 min. Each run included 20 trials of each frame condition (Help/Harm) that were pseudo-randomized. Thus, each condition contained 40 trials in total. Before the scanning, participants were familiarized with the task with a practice block consisting of eight trials. After the experiment, the participants received remuneration according to their task performance (120-150 Chinese RMB, ∼20 U.S. dollars) and a debriefing was given by the experimenter.

Neuroimaging data acquisition and preprocessing

We used a Siemens TrioTim 3.0T MRI machine for data acquisition. Functional volumes were acquired using multiple slice T2-weighted echo planar imaging sequences with the following parameters: repetition time = 2000 ms, echo time = 30 ms, flip angle = 90°, field of view = 224 × 224 mm2, 33 slices covering the entire brain, slice thickness = 3.5 mm, voxel size = 3.5 × 3.5 × 4.2 mm3.

fMRI data were preprocessed in SPM12 (Wellcome Department of Imaging Neuroscience, University College London; http://www.fil.ion.ucl.ac.uk/spm). Images were slice-time corrected, motion-corrected, and normalized to the Montreal Neurological Institute (MNI) space for each individual with a spatial resolution of 3 × 3 × 3 mm3. Images were then smoothed using an isotropic 6 mm Gaussian kernel and high-pass filtered at a cutoff of 128 s.

Statistical analysis

Univariate analysis

General linear model (GLM) 1

We ran a parametric analysis that included all the trials with parametric modulation, which indicates the strength of the social framing effect on a trial-by-trial basis. Specifically, we collapsed the decision phase of all trials (including both frame conditions) into one regressor. The presentations of victim information and feedback phase were also included to control related blood-oxygen-level-dependent (BOLD) responses. Parametric modulations of “to what extent the participant's behavior was consistent with the framing effect” (i.e., the weight of framing effect for every single trial) and reaction time were added to the first regressor (i.e., the decision phase). The weight of each trial was set up as follows: for the Harm frame condition, since “not to harm” was the option that was consistent to the framing effect and “to harm” was the option that ran counter to it, we therefore assigned 4 to the 90% probability toward the “not to harm” side and −4 to the opposite case. Choosing 50% was always assigned as 0. For the Help frame condition, the 90% probability toward the side that was consistent with the framing effect (i.e., not to help) was assigned with 4 and the other side was assigned with −4.

This GLM analysis can reveal the strength of framing effect on a trial-by-trial basis. As the location of the avatar at the beginning of the decision phase was randomly set across trials, parametric modulation of the number of button-presses in each trial was also added according to the corresponding regressor to exclude linear signal changes of finger movement. Six parameters generated during motion correction were entered as covariates. Low-frequency drifts in signal were removed using a high-pass filter with a cutoff at 128 s. Parameter-estimated images for individual participants were calculated across the whole brain.

In addition, we ran an additional analysis to better illustrate the neural correlates of the social framing effect for two frame conditions seperately (i.e., the Harm frame and Help frame) on a group level. At the first level, we built a GLM that included all the trials under the Harm frame and the Help frame condition, respectively. Other settings of this GLM were consistent with the aforementioned GLM 1. At the second level, we set up a multiple regression analysis where the individual β maps were regressed against individual difference of the social framing effect for each frame condition.

A random-effects analysis for the entire group was performed in SPM12 on the parameter-estimated images for all participants. The significance level was set to p < 0.001 uncorrected at the voxel level and to an extent threshold of p < 0.05 with false discovery rate correction (FDR) at the cluster level.

GLM 2

GLM 2 was inspired by De Martino et al. (2006), which calculated the economic framing effect as the contrast of [Gain framesure + Loss framegamble] > [Gain framegamble + Loss framesure]. Since the classic approach of De Martino et al. (2006) has been widely applied in neuroimaging studies (e.g., Roiser et al., 2009; Xu et al., 2013; Li et al., 2017), using a similar contrast helps compare our results with previous findings about the nonsocial framing effect.

The framing effect on the neural level was calculated as the contrast of [Harm framenot to harm + Help framenot to help] > [Harm frameto harm + Help frameto help]; that is, the difference between trials in which participant preference was affected by the frame (prefer “not to harm” in the “Harm frame” condition or prefer “not to help” in the “Help frame” condition) and trials in which participant preference ran counter to the frame (prefer “to harm” in the “Harm frame” condition or prefer “to help” in the “Help frame” condition).

Two regressors (i.e., [Harm framenot to harm + Helpframenot to help] and [Harm frameto harm + Help frameto help]) were included accordingly. Participant preference was usedto categorize the data. For instance, if they selected a possibility > 50% for “not to harm” in a Harm frame trial, then this trial would be counted into the Harm framenot to harm category. The trials in which participants showed no preference (i.e., selecting 50%) were excluded from these two regressors; these trials, as well as the presentations of victim informationand feedback phase, were included to control related BOLD responses.

This binary contrast GLM 2 also provides a basis for the follow-up multivoxel pattern analysis (MVPA) and psychophysiological interaction analysis (PPI) as they both require separating the trials into two comparable categories. However, this classification method disregarded the trials in which participants showed no preference between two outcomes (i.e., selecting 50%), and it might have brought the issue of imbalanced number of trials across experimental conditions. While the GLM 2 might not be as precise as the GLM 1 methodologically, their results showed highly similar patterns (see Results).

Region of interest (ROI) analysis

Activity intensity within ROIs associated with the social and economic framing effects

To better address the findings derived from the whole-brain analysis, we performed further analyses for some predefined ROIs. We hypothesized that the social framing effect may be induced by different levels of involvement of specific regions during decision-making, such as mentalizing. To test this hypothesis, we selected ROIs from a previous meta-analysis concerning mentalizing/theory of mind, namely, MNI coordinate [−55, −59, 19] for the left TPJ and MNI coordinate [49, −56, 19] for the right TPJ (rTPJ) (Schurz et al., 2014). A good way to further support our viewpoint (that the social framing effect is distinct from the economic framing effect reported in the literature) is to run ROI analysis with the ROIs closely related to the economic framing effect (i.e., bilateral amygdala: [−30, 6, −20] for the left and [22, −6, −14] for the right; the dorsal ACC [dACC]: [6, 26, 42]) (adapted from Xu et al., 2013) to compare with ROIs revealed in the social framing effect. The mean parameter estimates were calculated within the sphere (radius = 6 mm) centered in the bilateral TPJ, as well as in the bilateral amygdala and dACC for each participant in the parametric analysis of the strength of social framing effect (GLM 1). We then performed one-sample t tests on the extracted values to examine whether they were significantly different from zero. We predicted that only in the bilateral TPJ, the parametric estimates would be significantly different from zero. In contrast, for the ROIs associated with the economic framing effect (bilateral amygdala and dACC), their activations should not reach significance. If that was the case, it could be regarded as evidence that the two kinds of framing effects (social vs nonsocial/economic) recruited distinct neural correlates.

Classification within ROIs

To further explore whether the activation pattern was different between trials in which participant preference was consistent with the framing effect and trials in which participant preference ran counter to the framing effect, we performed MVPA within the predefined ROIs (i.e., MNI coordinate [−55, −59, 19] for the left TPJ and MNI coordinate [49, −56, 19] for the rTPJ) (see Schurz et al., 2014). This method reduced the number of voxels used for classification (and therefore the number of free parameters that can lead to overfitting; for similar approaches, see Kuhl et al., 2011; Murphy et al., 2017). The classifier was trained and tested on individual parameter estimates image for [Harmframenot to harm + Help framenot to help] and [Harm frameto harm + Help frameto help] obtained in GLM 2.

We first defined a sphere (radius = 6 mm) around a given voxel within the ROIs (Haynes et al., 2007; Bode and Haynes, 2009). For each voxel within the ROI, we used a linear support vector machine (LIBSVM; with default hyperparameters). We adapted a leave-pair-out cross-validation procedure; thus, in the model, we have 54 (27 + 27) samples (participants) and 33 features (voxels). Although the model might suffer from limited sample size (n = 54), similar sample sizes have been commonly reported in previous studies (e.g., Shirer et al., 2012; Wang et al., 2016), especially in clinical research (e.g., Welsh et al., 2013; Dyrba et al., 2015).

The significance level (i.e., p value) of decoding accuracies was estimated by permutation tests (Tusche et al., 2016). We performed classifications with shuffled labels for 1000 times to obtain a null distribution. The formula to compute p values is as follows: p = (ranking + 1)/(number of permutation).

Functional connectivity analysis (PPI)

Given that the bilateral TPJ was found to play an important role in the social framing effect (see Results), we aimed to further explore whether and how the bilateral TPJ interacts with brain regions involved in decision-making. For this purpose, we performed PPI analysis (Friston et al., 1997) using the bilateral TPJ identified in our whole-brain univariate analysis (GLM 2) as seed regions, namely, MNI [−45, −63, 27] for the left TPJ and MNI [60, −63, 12] for the rTPJ separately. For each participant, the mean time series for each of the two seed regions were extracted and adjusted using the F-contrast for the regressors. We first set the coordinate of the peak voxel in each seed region as a landmark and searched for individual peak voxels that survived the p < 0.05 threshold around the landmark within a 6 mm radius sphere in each ROI. Each GLM included the following PPI regressors: (1) the main effect of seed-region activity, (2) the main effect of the contrast of [Harm framenot to harm + Help framenot to help] > [Harm frameto harm + Help frameto help], and (3) their interaction. These regressors corresponded to PPI.Y, PPI.P, and PPI.ppi in the design matrix. The six head-motion parameters were also entered into the GLM as covariates to regress out any head-motion artifacts. Low-frequency drifts in signal were removed using a high-pass filter with a cutoff at 128 s. After model estimation, the PPI.ppi regressor for the contrast of [Harm frameto harm + Help frameto help] and [Harm framenot to harm + Help framenot to help] was entered into a random-effects analysis for the entire group. The significance level was set to p < 0.001 uncorrected at the voxel level and to an extent threshold of p < 0.05 with FDR correction at the cluster level.

Results

Behavioral results

As we stated previously, making more costly helping decisions in the Harm frame compared with the Help frame condition should result in a significant social framing effect. We used the weight value defined in GLM 1 (−4 to 4) to quantify the framing effect strength. Here, the direction of this weight value was consistent with the preference to “not harming others” in the Harm frame condition, whereas it ran counter to the preference to “helping others” in the Help frame condition. Therefore, if there was no significant difference in decision preference between the two frame conditions, the sum of weight from all trials (including both conditions) should not be different from zero. A two-sided one-sample t test was performed to examine whether the framing effect strength was significantly different from zero on the group level, and the results confirmed our hypothesis (framing effect size: 0.53 ± 0.12 [mean ± SE], t(26) = 4.36, p < 0.001) (Fig. 2).

Another two-sided paired-sample t test was performed to compare the reaction time between the two conditions, which showed no significant effect (Harm frame: 2629.58 ± 55.13 ms; Help frame: 2648.81 ± 61.48 ms [mean ± SE], t(26) = −0.54, p = 0.59).

Univariate analysis

GLM 1

The univariate analysis was aimed to reveal how brain activities were covaried with the behavioral strength of framing effect on a trial-by-trial basis within all experimental trials. The parametric modulation analysis revealed significant activations in the right calcarine gyrus (peak MNI [18, −84, 3], cluster size = 349, t(26) = 8.09), right cerebellum (peak MNI [6, −57, −51], cluster size = 83, t(26) = 5.75), left cuneus (peak MNI [−9, −63, 27], cluster size = 80, t(26) = 5.60), rTPJ (peak MNI [51, −54, 27], cluster size = 53, t(26) = 5.54), left postcentral gyrus (peak MNI [−39, −30, 63], cluster size = 154, t(26) = 5.21), and left TPJ (peak MNI [−42, −48, 24], cluster size = 74, t(26) = 5.16) (Fig. 3A; Table 1).

Both the multiple regression analysis under the Harm frame condition and that under the Help frame condition revealed significant activations in the rTPJ (Harm frame: peak MNI [48, −75, 39], cluster size = 24, t(26) = 4.92); Help frame: peak MNI [51, −42, 45], cluster size = 22, t(26) = 4.24) (Fig. 3A). The significance level for this multiple regression analysis was set at p < 0.001 uncorrected at the voxel level, not survived FDR correction p < 0.05 at the cluster level.

GLM 2

To facilitate further MVPA and PPI analysis, as well as to draw a direct comparison with previous findings about the economic framing effect (e.g., De Martino et al., 2006; Xu et al., 2013), we also ran the contrast of [Harm framenot to harm + Helpframenot to help] – [Harm frameto harm + Help frameto help]. We found that the contrast revealed significant activation in the rTPJ (peak MNI [60, −63, 12], cluster size = 62, t(26) = 4.96), right calcarine gyrus (peak MNI [18, −81, 3], cluster size = 187, t(26) = 6.40), and left precentral gyrus extending to the postcentral gyrus (peak MNI [−42, −24, 66], cluster size = 82, t(26) = 5.24), and left TPJ (peak MNI [−45, −63, 27], cluster size = 41, t(26) = 4.54) (Fig. 3B; Table 2).

ROI-based analysis

Activity intensity within ROIs revealed in social and economic framing effects

Regarding the brain regions revealed in the social framing effect, two-sided one-sample t tests revealed that the activation revealed in GLM 1 was significantly larger than zero (left TPJ: 0.03 ± 0.05, t(26) = 2.68, p = 0.01; rTPJ: 0.02 ± 0.04, t(26) = 2.77, p = 0.01). For the regions revealed in the economic framing effect, the bilateral amygdala and dACC showed no differences with zero (left amygdala: t(26) = 0.30, p = 0.77; right amygdala: t(26) = −0.14, p = 0.89; dACC: t(26) = 1.04, p = 0.31) (Fig. 3C).

Classification within ROIs

We found that the rTPJ could significantly classify between [Harm framenot to harm + Help framenot to help] trials and [Harm frameto harm + Help frameto help] trials in the 1000× permutation (classification accuracy = 54.47%, p = 0.001), but the left TPJ could not (classification accuracy = 49.93%, p > 0.05) (Fig. 3D). To demonstrate that the activations of rTPJ revealed in GLM 1, GLM 2, and the rTPJ ROI selected in meta-analysis are converging within the rTPJ region, we overlapped these images together with a functional rTPJ mask (see also Bzdok et al., 2013) (Fig. 3E).

PPI analysis

We performed PPI analyses to test whether the functional connectivity between the bilateral TPJ and other brain regions was modulated by frame manipulation. For the seed region of the left TPJ, we did not observe any difference in functional connectivity between the [Harmframenot to harm + Help framenot to help] trials and the [Harm frameto harm + Help frameto help] trials. However, for the seed region of the rTPJ,we found significant difference in functional connectivity of the medial prefrontal cortex (mPFC) for [Harm frameto harm + Help frameto help] trials > [Harm framenot to harm + Helpframenot to help] trials (peak MNI [15, 45, 18], cluster size = 110, t(26) = 5.16) (Fig. 4A).

To explore whether brain functional connectivity was associated with the observed social framing effect, we calculated the correlation between the functional connectivity strength of rTPJ to mPFC andthe behavioral social framing effect. Pearson's correlation analysis revealed that the functional connectivity between the rTPJ and mPFC predicted the social framing effect size (r = 0.39, p = 0.04) (Fig. 4B).

Experiment 2 (tDCS)

Materials and methods

Participants

Sixty-two right-handed participants were recruited from local universities for participation in the tDCS experiment. None of these persons hadparticipated in Experiment 1. Two participants were excluded due to their absence on the second experimental day, leaving 60 participants in the final sample.

All participants were screened for histories of neurologic disorders, brain injury, or developmental disabilities. All had normal or corrected-to-normal vision. The study wasconducted according to the ethical guidelines and principles of the Declaration of Helsinki and was approved by the Medical Ethics Committee of Shenzhen University Medical School. All participants provided written informed consent after they fully understood the procedures.

Experimental design and statistical analysis

To test the causal role of the rTPJ in the social framing effect (compared with the nonsocial one), we performed two experimental sessions using tDCS. To better control individual difference, which might strongly influence the results of tDCS experiment, we used a novel way developed by Zhang et al. (2016). The sample was separated into two groups, one of which (n = 30, 15 women, age: 21.9 ± 1.9 years) received anodal and sham stimulation over the rTPJ in two experimental sessions on 2 different days (separated by 1 week); the time sequence of receiving anodal and sham stimulation was counterbalanced across participants. The second group (n = 30, 15 women, age: 20.87 ± 2.3 years) received cathodal and sham stimulation over the same region in two experimental sessions, the time sequence of which was also counterbalanced across participants. In this way, the effect of anodal stimulation can be directly compared with that of sham stimulation within the same group. Likewise, the effect of cathodal stimulation can be directly compared with that of sham stimulation within the same group. Since these comparisons were both conducted on the within-subject level, the effect of individual difference would be better controlled.

Each experimental session included two tasks (i.e., social and nonsocial framing). The social framing task was the same as that in Experiment 1, but its trial number was reduced to 25 per condition (Harm frame vs Help frame). The nonsocial framing task was adapted from De Martino et al. (2006), in each trial of which participants were asked to select between a sure option (i.e., only retain a portion of the reward) and a gambling option; the expected values of the two options were identical within each trial, but the sure option was described as either a gain or a loss. We excluded the original control condition (“catch” trials: the expected values of two options were unbalanced) and retained 32 trials for each condition (Gain frame vs Loss frame). The trial number was modified to shorten the total amount of time of the tDCS experiments. Consequently, each task lasted for 8 min, and there was a 1.5 min rest between them. The order of the two tasks was counterbalanced across participants. After the experiment, participants received remuneration (∼100 RMB) according to their task performance.

tDCS parameters

A constant electrical current of 2 mA was applied by a saline-soaked pair of surface sponge rubber electrodes and delivered by a battery-driven transcranial stimulator (Brainstim, EMS). It was adjusted to induce cortical excitability of the target area without any physiological damage. tDCS started 8 min before the task and was delivered during the whole course of the experiment. For sham stimulation, the electrodes were placed in the same positions as for the anodal/cathodal stimulation, but the stimulator was only turned on for the initial 30 s. This method of sham stimulation has been proven to be reliable (Gandiga et al., 2006; Nihonsugi et al., 2015).

The stimulation site in our study was localized using the EEG 10/20 system. A 5 × 5 cm electrode was placed over the rTPJ area (at the 10-20 electrode positions between CP6 and P6) while a reference electrode was positioned above the left eyebrow. Both electrodes were positioned firmly on the scalp with a plastic headband. The electrode montage and tDCS parameters were identical to those that successfully modulated cortical excitability of the rTPJ in previous studies (Jurcak et al., 2007; Santiesteban et al., 2012; Tang et al., 2017).

Results

For the social framing task, the framing effect size was calculated in the same way as Experiment 1. Consistent with the behavioral findings in Experiment 1, one-sample t test revealed that the social framing effect was significantly larger than zero (anodal/sham group: t(29) = 4.02, p < 0.001 for anodal stimulation; t(29) = 2.71, p = 0.011 for sham stimulation; cathodal/sham group: t(29) = 2.05, p = 0.047 for cathodal stimulation; t(29) = 2.46, p = 0.020 for sham stimulation), indicating that the frame manipulation was effective. We then performed paired-sample t test between anodal/cathodal and sham stimulation for each group separately. For the social framing task, the framing effect size significantly increased under anodal stimulation compared with sham stimulation (anodal vs sham: t(29) = 2.24, p = 0.03); meanwhile, the framing effect size decreased under cathodal stimulation compared with sham stimulation, which approached statistical significance (cathodal vs sham: t(29) = −1.86, p = 0.07) (Fig. 5A).

For the nonsocial framing task, consistent with the original reference (De Martino et al., 2006), the framing effect size in the nonsocial framing task was calculated as (Gain framesure + Loss framegamble) – (Gain framegamble + Loss framesure). One-samplet test revealed that the nonsocial framing effect was significantly larger than zero (anodal/sham group: t(29) = 2.20, p = 0.036 for anodal stimulation; t(29) = 4.75, p < 0.001 for sham stimulation; cathodal/sham group: t(29) = 2.55, p = 0.016 for cathodal stimulation; t(29) = 3.60, p = 0.001 for sham stimulation), indicating that the frame manipulation was effective. However, the difference in framing effect size between anodal/cathodal stimulation and sham stimulation was nonsignificant (anodal vs sham: t(29) = 1.06, p = 0.30; cathodal vs sham: t(29) = 0.35, p = 0.73) (Fig. 5B), indicating that the nonsocial framing effect was insensitive to tDCS stimulation on the rTPJ (Fig. 5B).

Regarding the reaction time results, we detected no significant effect in either task.

Discussion

In this study, we explored the neural circuit of the social framing effect, which might involve important brain regions related to social cognition. A novel task has been developed for this purpose, in which participants may maximize reward at the expense of exposing their victim to the risk of receiving a painful shock. In the Harm frame condition, the shock is described as if it is the consequence of the participants' own action; in the Help frame condition, it is implied that the shock delivered is part of the task, but participants could help the victim to avoid it. Since avoiding harming others is a strong, universal motive among human beings, we predicted that, compared with the Help frame condition, participants would be more likely to select the costly helping option in the Harm frame condition.

Consistent with this hypothesis, the behavioral results in Experiment 1 revealed that participant preference to the costly helping option significantly increased in the Harm frame condition than in the Help frame condition, which was analogous to the classic social framing effect. On the brain-imaging level, the (bilateral) TPJ, (right) calcarine gyrus, (left) cuneus, (right) cerebellum, and (left) postcentral gyrus were more activated as a function of the social framing effect size. We also examined neural activations that covaried with the framing effect on a group level. The results showed that, in both frame conditions, the BOLD activation of the rTPJ increased when participants showed a stronger framing effect. Follow-up permutation test revealed that the rTPJ and its functional connectivity with the mPFC showed a more reliable relationship with the social framing effect than its left counterpart. Given that brain-imaging techniques are constrained in making causal inference (Ramsey et al., 2010), we conducted a separate tDCS experiment to modulate rTPJ activity. Results of this Experiment 2 show that, compared with sham stimulation, the social framing effect was stronger under anodal stimulation but became weaker under cathodal stimulation (marginally significant). In contrast, the nonsocial framing effect in the gambling task was insensitive to tDCS manipulation. Overall, we confirmed the importance of the TPJ to the social framing effect.

Previous studies have shown that a key function of the TPJ is to differentiate one's own from the other's perspective (Frith and Frith, 2010; Speitel et al., 2019). TPJ activation has been frequently reported in social decision-making tasks, especially when those tasks engage other-regarding considerations (Morishima et al., 2012; Tusche et al., 2016; Park et al., 2017). In addition, the current results revealed that the rTPJ weighs more heavily on the social framing effect than does its left counterpart. This hemispheric asymmetry has also been supported by the literature, as the rTPJ has been more strongly related to social processes (Krall et al., 2015). In our opinion, the decision “to harm” is more morally reprehensible than “not to help,” which may trigger a stronger conflict between moral values and material concerns. Previous studies have indicated that the rTPJ may be responsible for representing this conflict in decision-making (Berns et al., 2012; Morishima et al., 2012). Compared with the Help frame, the Harm frame in our task emphasized the “harmful” consequences to others and therefore triggered a tendency to avoid moral conflicts. As a result, the participants were more likely to avoid shocking others at the expense of their own gain.

An alternative interpretation is associated with the idea that the rTPJ is specialized for reasoning regarding the affective and cognitive mental states of others (Saxe, 2006; Zhu et al., 2019). It is possible that, under the Harm frame condition, the participants experienced a stronger inferred feeling state of their victim associated with a shock, which in turn strengthened the feeling of guilt. Consequently, behavioral preference varied as a function of the sensitivity to physical pain of the victim across conditions. While follow-up research is needed to determine which interpretation is more appropriate, both of them are in line with the finding that activating the rTPJ decreases antisocial behavior (e.g., deception) (see Tang et al., 2017).

Regarding the social nature of the current paradigm, here we interpret the major findings from the perspective of social functions. However, it is undeniable that the rTPJ has also been associated with nonsocial functions, such as attentional reorienting and reallocation (for review, see Krall et al., 2015). Accordingly, one might suggest that rTPJ activations in the current fMRI data actually indicate the importance of attentional function to our social framing task. That is, the social frames influenced behavioral preference by modulating attentional allocation. But this hypothesis might encounter difficulties to explain why tDCS stimulation on the rTPJ did not affect individual decisions in the nonsocial framing (Gain/Loss) task as well, since previous studies have shown that attention allocation also plays an important role in economic risk-taking (e.g., Yechiam and Hochman, 2014; Zhang and Gu, 2018).

Further, the results of the PPI analysis highlighted the connection between the rTPJ and mPFC. As one of the cortical hubs, the mPFC is a key region for information integration and valuation (Knutson et al., 2007; McNamee et al., 2013). Using the gambling task, one of our previous studies found that the mPFC was positively coupled with the bilateral amygdala under the nonsocial framing effect context, indicating the influence of emotional information from the amygdala to the mPFC (Xu et al., 2013). The current study also showed that the strength of the functional connectivity between the rTPJ and mPFC predicted the social framing effect, which indicates the importance of the connection between the mPFC and TPJ (instead of the amygdala) under social contexts. It is worth noting that the TPJ and mPFC are involved in the same mentalizing network (Bault et al., 2011; Mars et al., 2012). The significance of the TPJ-mPFC connection in the social framing task may indicate the mechanism of how social information transfers between the TPJ and the mPFC to bias decision preference when people receive the same offers that are framed differently.

Aside from the way of framing, the two options in different frame conditions (i.e., “not to harm” vs “to help”) also differed in the level of agency recruitment. That is, the option “not to harm” was worded as an inaction, whereas the option “to help” was worded as an action. Regarding that, the current results might have been affected by the “omission bias,” which refers to a tendency to avoid regret caused by actions compared with regret caused by inactions (Baron and Ritov, 2004). We admit this possibility but suggest that the experimental effects associated with the omission bias were limited for two reasons. First, the difference between the two options in the level of agency recruitment was not emphasized in our task instruction. Second, seeing that actively moving the avatar to modulate outcome probabilities could be understood as an “action” while leaving the avatar at the starting point could be understood as an “inaction,” the influence of the omission bias might actually be balanced across conditions. Nonetheless, it would be necessary for future studies to use alternative paradigms to better control the omission bias.

To sum up, using fMRI and tDCS, respectively, the two experiments in the current study consistently showed that the social framing effect was strongly associated with the rTPJ. Stronger rTPJ activations might reflect a higher level of moral conflict and/or mentalizing with others when the social responsibility for participants regarding the shock was emphasized by the option frame (i.e., the Harm frame). Consequently, the participants were more prone to “harm aversion” and selected costly helping. These findings may shed light on the issue of enhancing prosocial-helping behavior by manipulating verbal information (i.e., nudges; see Coventry et al., 2016).

Finally, some limitations should be noted. Regarding the technical issues, one drawback of the MVPA in the current study is that the sample size was relatively small for machine learning algorithm, although some previous studies used similar sample sizes (e.g., Shirer et al., 2012; Wang et al., 2016). Moreover, the results of the second-level multiple regression analysis did not survive FDR correction and the two rTPJ clusters revealed in the Harm and the Help frame conditions did not overlap, also possibly due to the relatively limited sample size. We should consider these results with caution and further verification with a larger sample size would be needed. In addition, the paradigm used in this study was different from those in previous studies on the social framing effect (e.g., the Community Game vs Wall Street Game frame in economic cooperation games) (see Liberman et al., 2004). We did not choose those paradigms partly because of the heterogeneous findings in the literature (e.g., Rege and Telle, 2004; Cubitt et al., 2011; Dreber et al., 2011; Ellingsen et al., 2012). Also, we were interested in investigating the influence of social frames on different decision problems beyond economic cooperation. We believe that the current findings have general implications in the brain mechanisms of the social framing effect, but follow-up examinations would surely be necessary.
