Finger (verbal instructions removed) Millisecond Software thanks Lisa Graf for generously sharing the German translations! ___________________________________________________________________________________________________________________ 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.iqx'. 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. "glücklich" face paired with word "freudig") or an incongruent one (e.g. "happy face" paired with word "wütend"). 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 FILE INFORMATION ___________________________________________________________________________________________________________________ The default data stored in the data files are: (1) Raw data file: 'abcdemotionalstroop_ln_raw*.iqdat' (a separate file for each participant)* /testdate: the testdate information entered at the start of testing /id: the id entered at the start of testing /language: the selected language build: Inquisit build computer.platform: the platform the script was run on (win/mac/ios/android) date, time, subject, group: date and time script was run with the current subject/groupnumber blockcode, blocknum: the name and number of the current block trialcode, trialnum: the name and number of the currently recorded trial (Note: not all trials that are run might record data;
