Measuring the stare-in-the-crowd effect: a new paradigm to study social perception

Social perceptual ability plays a key role in successful social functioning. Social interactions demand a number of simultaneous skills, one of which is the detection of self-directed gaze. This study demonstrates how the ability to accurately detect self-directed gaze, called the stare-in-the-crowd effect, can be studied using a new eye-tracking paradigm. A set of images was developed to test this effect using a group of healthy undergraduate students. Eye movements and pupil size were tracked while they viewed these images. Participants also completed behavioral measures about themselves. Results show that self-directed gaze results in significantly more looking by participants. Behavioral predictors of gaze behaviors were not identified, likely given the health of the sample. However, correlations with variables are reported to explore in future research.
