Social vision
[1] Thin-slice vision refers to the accuracy with which observers are able to correctly identify imperceptible characteristics of a person after watching the individual alone or acting in a group for only a short amount of time.[12] In another example of attitudes being quickly perceived in thin-slice videos, subjects were given ten-second silent clips of teachers giving a lecture to a classroom.[15] In another study that presented observers with silenced admissions interviews at a psychiatric hospital, both experts and non-experts in mental health were correct in assessing whether patients did or did not suffer with depression 88% of the time on average.A series of studies in 1999 provided observers with silent clips that were either ten-seconds or one-second long in which heterosexual and homosexual subjects discussed their academic and extracurricular activities.[3] These results range from the effectiveness of teachers during instruction to the future performance of health practitioners or likelihood of a crime being committed, all judged from silent clips.In 1993, college and high school teachers were videotaped while teaching classes, and silent thin-slice videos of these lectures were provided to naïve judges.[25] An additional study provided observers with one-minute slices of silent behavior where physical therapists interacted with elderly patients.[34] Body motion is highly diagnostic of sex category membership, and observers have proven to reliably identify the gender of a walker in a point-light display.[35] Untrained observers have additionally proven to be adept at assessing another person's reproductive fitness based on light display motion.[38] People have also proven to be highly reliable at detecting an individual's sexual orientation from dynamic motion in point-light displays as well.[28] However, this leads to the prediction that difficulty in social interaction may be in part due to the inability to read body motion accurately.
