The CATS and CATS-R were created by: Sarah G. Schaffer, PhD Karen B. Froming, PhD Amanda L. Gregory, PhD C. Michael Levy, PhD Paul Ekman, PhD Reference for Means and Standard Deviations used to calculate z-scores: Emotion Processing: The Comprehensive Affective Testing System. User Manual. Published 2006 by Psychology Software Inc ___________________________________________________________________________________________________________________ TASK DESCRIPTION ___________________________________________________________________________________________________________________ Subtest2: AFFECT DISCRIMINATION Participants are presented 12 pairs of vertically stacked faces and have to decide whether the faces are of the same person of whether the faces are of different people. The two faces always come from the same actor but the emotion the actor is showing may or may not be the same (i.e., Happy, Sad, Angry, Frightened, Surprised, Disgusted, or Neutral) ___________________________________________________________________________________________________________________ DURATION ___________________________________________________________________________________________________________________ the default set-up of the script takes appr. 2 minutes to complete ___________________________________________________________________________________________________________________ DATA FILE INFORMATION ___________________________________________________________________________________________________________________ The default data stored in the data files are: (1) Raw data file: 'catsr_subtest2_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 subtest: "subtest2" //if the subtest is run via a batch script that collects gender/age/taskOrder information: age: the age of the participant gender: Female; Male; Other taskOrder: the selected task order 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. trialCount: trial counter subtest2_testitem: the index of the selected image testitem: the presented image correctResponse: the dedicated correct response: 1 = same 2 = different selectedResponse: 'same' or 'different' correct: accuracy of response: 1 = correct response; 0 = otherwise RT: cumulative response latency: measured from onset of image until 'nextButton' is pressed (2) Summary data file: 'catsr_subtest2_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) subtest: "subtest2" //if the subtest is run via a batch script that collects gender/age/taskOrder information: age: the age of the participant gender: Female; Male; Other taskOrder: the selected task order T2_rawscore: the number of correct responses in subtest2 T2_rawscore_corrected: the number of correct responses in subtest2, corrected (Note: in this subtest rawscores get corrected for males over 39 by adding +1 to the rawscore) T2_zscore: the z-score for the corrected T2_rawscore (Note: z-scores get calculated using the overall mean and standard deviation) T2_propCorrect: proportion correct responses in subtest2 T2_RT: mean response time (in ms) in subtest2; measured from onset of image until 'nextButton' is pressed T2_corrRT: mean response time (in ms) of CORRECT responses in subtest2; measured from onset of image until 'nextButton' is pressed + results from individual questions * 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 Testblock of 12 trials - 6 trials with identical faces - 6 trials different faces The order of the images is predetermined. Participants can select button 'same' or 'different'. Responses can be changed until 'next' is pressed. If button 'repeat' is pressed, nothing happens in this script as the images are still on screen. Note: By setting parameters.showAdvanceButton to true, a '?'-button appears in the upper right corner. If pressed, the next scheduled test item is skipped. ___________________________________________________________________________________________________________________ STIMULI ___________________________________________________________________________________________________________________ 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.
