Borchert (katjab@millisecond.com) for Millisecond Software, LLC Script Copyright © 03-22-2022 Millisecond Software ___________________________________________________________________________________________________________________ BACKGROUND INFO ___________________________________________________________________________________________________________________ This script implements the Transgender Affect Misattribution Procedure (Transgender AMP) by Kanamori et al (2020), The Transgender AMP is a priming procedure using supraliminal primes to assess implicit attitudes towards transgender. The rationale of the AMP is that people, despite instructions to the contrary, cannot ignore (supraliminal) primes and will automatically attribute their attitudes towards the prime (category) to stimuli presented after.

Thus, trialnum may not reflect the number of main trials run per block. blockCounter: blockCounter (each block runs 10 trials) trialCounter_perblock: trialCounter per block prime: the currently presented prime word prime_index: stores the itemnumber of the current prime stimulus target: the currently presented Chinese character target_index: stores the itemnumber of the current target stimulus response: scancode of the response button pressed (Note: scancode of the number button is not equal to the selected number) responseText: the actual number button pressed: 3,4,7,8 (pressed key) rating: the reverse coded response on a scale from 1 (pleasant) - 4 (unpleasant) (see Kanamori et al, 2020) '3' -> rating of 4 '4' -> rating of 3 '7' -> rating of 2 '8' -> rating of 1 latency: response latency (in ms); in this script: measured from onset of chinese character (2) Summary data file: 'amp_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) ////////////// Ratings: rating on a scale from 1 (pleasant) - 4 (unpleasant) -> see Kanamori et al, 2020 for more info => higher scores indicate greater prejudice ///////////// meanRating_primeA: mean rating for primeA (transgender prime words) meanRT_primeA: mean rating response time (in ms) for primeA meanRating_primeB: mean rating for primeB (neutral prime words) meanRT_primeB: mean rating response time (in ms) for primeB ___________________________________________________________________________________________________________________ EXPERIMENTAL SET-UP ___________________________________________________________________________________________________________________ * 1 Demo Trial (with prime and target not used during test) * 10 Test blocks of 10 trials randomly selecting from primeA (transgender words)/primeB (neutral words) (Note: the 100 test trials are run by one block but a blockcounter keeps track of the blocks. Prime Stimuli are reset after each of these blocks, so each prime is run 10 times) * all 100 targets are run once in random order Trials: * prime is presented for 100ms * prime is replaced by a blank stimulus for 100ms * the target is presented for 100ms and then covered up by a mask until response is made * no iti ___________________________________________________________________________________________________________________ STIMULI ___________________________________________________________________________________________________________________ see section Editable Stimuli; all stimuli are presented white on black - 10 prime words from Kanamori et al (2020) - 1 demo work provided by Millisecond Software - 100 Chinese characters (+ 1 demo image) taken from Inquisit AMP.iqx script (colors reversed) ___________________________________________________________________________________________________________________ INSTRUCTIONS ___________________________________________________________________________________________________________________ see section Editable Instructions Instructions modeled after Kanamori et al (2020) with some edits ___________________________________________________________________________________________________________________ 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:
