___________________________________________________________________________________________________________________ ABCD Emotional Stroop (Version 2) - 'good' button on the right, 'bad' button on the left- (i-pad Version for in person testing) ___________________________________________________________________________________________________________________ Script Author: Katja Borchert, Ph.D. (katjab@millisecond.com) for Millisecond Software, LLC Date: 10-12-2018 last updated: 10-16-2023 by K. Borchert (katjab@millisecond.com) for Millisecond Software, LLC Script Copyright © 10-16-2023 Millisecond Software This script has been made available to the Millisecond Software Library by the ABCD Research Consortium. The script was optimized for ABCD to be run on ipads for in person testing. ___________________________________________________________________________________________________________________ BACKGROUND INFO ___________________________________________________________________________________________________________________ This Inquisit script implements an Emotional Stroop Script designed for a touchcreen. The Inquisit script is based on an existing e-prime script by Dr. Marie Banich. This script can be run on its own or in conjunction with script 'batch.iqjs'. The batch script counterbalances the assignment to Stroop version one (lp = left positive) and Stroop version two (ln = left negative). ___________________________________________________________________________________________________________________ TASK DESCRIPTION ___________________________________________________________________________________________________________________ Participants categorize words as "good feeling" (happy, joyful) or "bad feeling" (angry, upset). The words are presented on the top or bottom of images. The image either show a word congruent face emotion (e.g. "happy" face paired with word "joyful") or an incongruent one (e.g. "happy face" paired with word "angry"). Images depict happy and angry emotions of teens. Participants work through 2 test blocks: one block presents 25% incongruent pairings and 75% congruent pairings, and the other block presents an equal number of congruent and incongruent pairings. Block order is determined randomly. ___________________________________________________________________________________________________________________ DATA OUTPUT DICTIONARY ___________________________________________________________________________________________________________________ The fields in the data files are: (1) Raw data file: 'abcdemotionalstroop_ln_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 keyAssignment: "leftnegative" => left response key is negative; right response key is positive 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 such as feedback trials. Thus, trialNum may not reflect the number of main trials run per block. wordPosition: 1 = word appears on top; 2 = word appears on bottom wordY: stores the vertical coordinate of the current word (in % of canvas height) congruence: 1 = congruent; 2 = incongruent (emotion word and emotion image depict opposite emotions) faceEmotion: "happy" vs. "angry" selectStim: itemnumber of selected stimulus stimulusItem: the presented stimuli in order of trial presentation 1) an empty stimulus (clearScreen) 2) presented image 3) presented word correctButton: stores the correct response button for the current trial response: the participant's response (selected response button) correct: accuracy of response: 1 = correct response;
