This script implements a computerized version of the revised Eyes Test; a test of social sensitivity. The script is based on:
Baron-Cohen, S., Wheelwright, S., Hill, J., Raste, Y., & Plumb, I. (2001). The 'Reading the Mind in the Eyes' Test Revised Version: A Study with Normal Adults, and Adults with Asperger Syndrome or High-functioning Autism. Journal of Child Psychiatry and Psychiatry, 42, 241-252

7 minutes
Participants are given 36 photographs of people's eyes and four word descriptions that describe the possible mental state of the person in question. Participants are asked to select the option that they think best describes the mental state of the person. There is no time limit to this test and participants can look up the descriptions of the words anytime they need to.
(1) Practice: 1 image
(2) Test: Part1: 17 images
(3) Test: Part2: 19 images
Trial: an image is presented with 4 surrounding words, guessing probability = 0.25
Chance Performance = 36*0.25 = 9 items
images are presented in a fixed sequence
