BACKGROUND INFO 	
___________________________________________________________________________________________________________________	

This script implements an example Stroop test with voice recording.
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.

Stroop, J, R. (1935). Studies of interference in serial verbal reactions.

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.

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
script.sessionid:					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. 
										
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)*

computer.platform:					the platform the script was run on (win/mac/ios/android)
script.startdate:					date script was run
script.starttime:					time script was started
script.subjectid:					assigned subject id number
script.groupid:						assigned group id number
script.sessionid:					assigned session id number
script.elapsedtime:					time it took to run script (in ms); measured from onset to offset of script
script.completed:					0 = script was not completed (prematurely aborted); 
									1 = script was completed (all conditions run)

* separate data files: to change to one data file for all participants (on Inquisit Lab only), go to section
"DATA" and follow further instructions
