Investigating the relationship between background luminance and self-reported valence of auditory stimuli
2022, Acta PsychologicaCitation Excerpt :As such, our results could also be influenced by dominance, the relationship of which to pupil size has not been systematically explored yet, which future work could endeavour. A general question that arises from this research domain is whether pupil-size adjustments through affective sounds have a functional role, in particular because pupil size can influence detection and discrimination performance (Campbell & Gregory, 1960; Mathôt & Ivanov, 2019; Woodhouse, 1975). The large pupil size in the negative condition may help with increasing visual sensitivity, hence detecting faint stimuli in the environment, which could be survival-relevant.
Human body motion captures visual attention and elicits pupillary dilation
2019, CognitionCitation Excerpt :Fluctuations in pupil size also occur as a result of changes in luminance in stimuli (Mathôt, 2018; Woodhouse, 1975). This pupillary light reflex has been suggested to be one of the main confounds in cognitive pupillometry (Sirois & Brisson, 2014; Woodhouse, 1975). Thus, we verified that the luminance levels of both motion categories did not significantly differ from each other.
Small-pupil versus multifocal strategies for expanding depth of focus of presbyopic eyes
2019, Journal of Cataract and Refractive SurgeryCitation Excerpt :The current modeling shows the familiar reality that expansion of the depth of focus typically is accompanied by a reduction in peak image quality (compare Figure 7 with Figures 8 and 9). Peak image quality was often generated with 2.0 to 3.0 mm pupils47,66,67 and depth of focus typically expanded with pupil diameters of less than 2.0 mm or more than 3.0 mm. The modeling also emphasized that the very different approaches of reducing pupil size or increases spherical aberration are both effective at expanding the depth of focus.
