The classic Stroop paradigm demonstrates the interference of word meaning on the naming of the color in which the words are written as measured by reaction time/accuracy differences to color-meaning congruent and color-meaning incongruent combinations. Reference: Stroop, J, R. (1935). Studies of interference in serial verbal reactions. Journal of Experimental Psychology, 18, 643-662. ___________________________________________________________________________________________________________________ TASK DESCRIPTION ___________________________________________________________________________________________________________________ Participants see color words in different colors. Some of the colorwords are printed in congruent colors (word meaning and color coincide), some of the colorwords are printed in incongruent colors (word meaning and color diverge). Participants are asked to say out loud the color of the word.

XXX minutes to complete (if no task duration is provided, please contact Millisecond Software (katjab@millisecond.com) ___________________________________________________________________________________________________________________ DATA FILE INFORMATION ___________________________________________________________________________________________________________________ The default data stored in the data files are: (1) Raw data file: 'stroopwithvoicerecording_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 such as feedback trials. Thus, trialnum may not reflect the number of main trials run per block. congruence: 1 = congruent 2 = incongruent stimulusitem: the presented stimulus response: the participant's response (voicerecord) latency: the response latency (in ms); measured from: onset of word (2) Summary data file: 'stroopwithvoicerecording_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)un) * 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 ___________________________________________________________________________________________________________________ 24 trials: 12 congruent, 12 incongruent 12 Congruent Trials: - 3 red words (present word: red), - 3 green words (present word: green), - 3 yellow words (present word yellow), - 3 blue words (present word blue) 12 Incongruent Trials: - 3 red words (present words: yellow, blue, green), - 3 green words (present words: yellow red, blue), - 3 yellow words (present words: red, blue, green), - 3 blue words (present words: yellow, green, red) ___________________________________________________________________________________________________________________ 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.
