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 Materials are downloadable from the following link: https://www.autismresearchcentre.com/arc_tests/ ___________________________________________________________________________________________________________________ TASK DESCRIPTION ___________________________________________________________________________________________________________________ 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. ___________________________________________________________________________________________________________________ DURATION ___________________________________________________________________________________________________________________ the default set-up of the script takes appr. 7 minutes to complete ___________________________________________________________________________________________________________________ DATA OUTPUT DICTIONARY ___________________________________________________________________________________________________________________ The fields in the data files are: (1) Raw data file: 'eyestest_raw*.iqdat' (a separate file for each participant)* build: The specific Inquisit version used (the 'build') that was run computer.platform: the platform the script was run on (win/mac/ios/android) date, time: date and time script was run subject, group: with the current subject/groupnumber session: with the current session id blockCode, blockNum: the name and number of the current block (built-in Inquisit variable) trialCode, trialNum: the name and number of the currently recorded trial (built-in Inquisit variable) Note: trialNum is a built-in Inquisit variable; it counts all trials run; even those that do not store data to the data file. gender: "f"(emale) vs. "m"(ale) (gender of image) trialCount: trial counter image: stores the current image name word1: stores the current word1 (top left) word2: stores the current word2 (top right) word3: stores the current word3 (bottom left) word4: stores the current word4 (bottom right) corrResp: the correct response (1-4) response: the participant's response: selected word (word1-word4) correct: accuracy of response: 1 = correct response; 0 = otherwise latency: the response latency (in ms) of current trial; measured from: onset of image until response is selected rt: the cumulative time (in ms) spent on the current image (includes time spent on dictionary); measured from onset of image until a word is selected countCorr: running count of correctly identified expressions (2) Summary data file: 'eyestest_summary*.iqdat' (a separate file for each participant)* inquisit.version: Inquisit version run computer.platform: the platform the script was run on (win/mac/ios/android) startDate: date script was run startTime: time script was started subjectId: assigned subject id number groupId: assigned group id number sessionId: assigned session id number elapsedTime: time it took to run script (in ms); measured from onset to offset of script completed: 0 = script was not completed (prematurely aborted); 1 = script was completed (all conditions run) generalPopulationMeanNumberCorrect: the reported correct count of the general population tested by Baron-Cohen et al (2001, p. 245) values.generalPopulationPropCorrect: proportion correct of the general population tested by Baron-Cohen et al (2001 ) generalPopulationSD: the reported standard deviation of correct counts of the general population tested by Baron-Cohen et al (2001, p. 245) countCorr: count of correctly identified expressions propCorrect: proportion correctly identified expressions => the higher the amount, the higher social sensitivity zValue: the z-value of the Correct Count (using the General Population Correct Count) pValue: the p-value of the correct count meanRT: mean latency (ms) of correctly identified expressions * separate data files: to change to one data file for all participants (on Inquisit Lab only), go to section "DATA" and follow further instructions ___________________________________________________________________________________________________________________ EXPERIMENTAL SET-UP ___________________________________________________________________________________________________________________ (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 Note: images are presented in a fixed sequence ___________________________________________________________________________________________________________________ STIMULI ___________________________________________________________________________________________________________________ provided by Millisecond Software - can be edited under section Editable Stimuli ___________________________________________________________________________________________________________________ INSTRUCTIONS ___________________________________________________________________________________________________________________ provided by Millisecond Software - can be edited under section Editable Instructions ___________________________________________________________________________________________________________________ EDITABLE CODE ___________________________________________________________________________________________________________________ check below for (relatively) easily editable parameters, stimuli, instructions etc. Keep in mind that you can use this script as a template and therefore always "mess" with the entire code to further customize your experiment. The parameters you can change are: /showSummaryFeedback: true (1): participants are given the number of correctly selected emotions and their median reaction time false (0): no performance feedback is provided at the end
