Procedure using CFS. Different images were presented into the subject's left and right eyes by using anaglyphs. Dynamic high-contrast random-noise patterns (10 Hz) were presented to the dominant eye, while low-luminance, low-contrast prime stimuli were presented to the nondominant eye. Subjects could report the dynamic noise but not the static image. Each trial started with a fixation cross for 500 ms, followed for 200 ms by a prime stimulus suppressed by CFS. Finally, a target stimulus masked by 70% additive noise was presented until the subject responded (maximum duration: 3 s) by pressing a key to indicate the category of the target stimulus.

The images used in Experiment 5. We used elongated stick figures as in Experiment 2 (left), diamond shapes (center), and cut circles (right). These three images presented in this experiment are rotated in 45° steps. For example, there are 0° images (A) and 135° rotated images (B).

Priming effects in Experiments 1, 2, and 3. Light and dark gray bars represent mean priming effects to tool targets and animal targets, respectively. Error bars indicate SEM. The pictures represent examples of the prime stimuli we used.
