BACKGROUND INFO 	
___________________________________________________________________________________________________________________	
This script implements an Aggression Themed Emotional Stroop task. 
The classic Stroop paradigm demonstrates the interference of word meaning on naming the color in which the words 
are written as measured by reaction time/accuracy differences to color-meaning congruent and color-meaning 
incongruent combinations.  The Aggression Stroop takes advantage of this basic Stroop interference effect 
by comparing responses to aggression related words, positive and negative words and neutral words.

The implemented procedure is based on:

Smith, P. & Waterman, M. (2003). Processing bias for aggression words in forensic and
nonforensic samples. Cognition and Emotion, 17, 681-701.

This script uses voice recordings. The accuracy of the responses needs to be manually scored
based on recorded files or use Tools -> Speech Recognition -> Analyze Recorded Responses.

TASK DESCRIPTION	
___________________________________________________________________________________________________________________	
Participants are presented words from 5 different categories (aggression, neutral,
positive, negative, color word) in four different colors (blue, red, yellow, green)
and are asked to speak out loud the color of the word.

___________________________________________________________________________________________________________________	
DURATION 
___________________________________________________________________________________________________________________	
the default set-up of the script takes appr. 5 minutes to complete

___________________________________________________________________________________________________________________	
DATA FILE INFORMATION 
___________________________________________________________________________________________________________________	
The default data stored in the data files are:

(1) Raw data file: 'emotionalstroopwithvoicerecording_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 such as feedback trials. Thus, trialnum 
										may not reflect the number of main trials run per block. 
									
values.target:						the currently selected target word
values.color:						the currently selected color

response:							the participant's response (recording of response)
									Note: the recording needs to be manually scored
									
latency: 							the response latency (in ms); measured from onset of word

(2) Summary data file: 'emotionalstroopwithvoicerecording_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)

EXPERIMENTAL SET-UP 
___________________________________________________________________________________________________________________	
1. Practice Block: 10 trials (not original; this script uses the words "one" to "ten" as practice stimuli)
2. Test Block: 125 trials (= 5 categories x 25 trials); trials are randomly sampled
without replacement

Since accuracy is not checked by this script (but has to be manually done based on the recorded voice files),
no error messages can be presented.

___________________________________________________________________________________________________________________	
STIMULI
___________________________________________________________________________________________________________________
* original stimuli by Smith & Waterman (2003) 
(due to a potential typo in the original article one word appeared
under two categories (Appendix2); we replaced it with a word that is similar in length and appearance
=> section Editable STIMULI-> Negative Words)

* each color appears 6 times in each category (the 7th pairing of word-color is random)
* color words "red", "yellow", "blue" and "green" are not used as targets
* 5 color words are repeats (see Smith & Waterman, 2003)

___________________________________________________________________________________________________________________	
INSTRUCTIONS 
___________________________________________________________________________________________________________________	
not original; can be easily altered 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.

The parameters you can change are:

/fixationcrosspresentationtime:				time (in ms) that fixation cross is presented (default: 500ms)
