BACKGROUND INFO 	
___________________________________________________________________________________________________________________	
This script implements a variant of the Remote Associates Test, a test of creativity, based on:

Mednick, S. A. (1962). The associative basis of the creative process.
Psychological Review, 69, 220-232.

Mednick, S. A. (1968). Remote Associates Test. Journal of Creative
Behavior, 2, 213-214.

TASK DESCRIPTION
___________________________________________________________________________________________________________________	
Participants are presented 30 triads consisting of 3 remotely associated words of the kind (paint/doll/cat) 
and are asked to come up with a fourth item that is associated with all three (here: "house").
The 30 triads are presented one-by-one (participants cannot go back and forth between items)
Each triad has a maximum timelimit of 1 minute.
  
___________________________________________________________________________________________________________________	
DURATION 
___________________________________________________________________________________________________________________	
the default set-up of the script takes max. 30 minutes to complete

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


(1) Raw data file: 'remoteassociatestest_itembyitem_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.
										
values.triadCount:				counts the triads
stimulusitem:					the presented triad
values.difficulty:				stores the difficulty for the current triad
values.solution:				stores the solution for the current triad

response:						the participant's response
correct:						the correctness of the response (1 = correct; 0 = incorrect)
latency: 						the response latency (in ms) (measured from onset of triad to submitting response)

(2) Summary data file: 'remoteassociatestest_itembyitem_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)
									
parameters.maxResponseWindow:	the maximum time (in ms) allowed for each item
parameters.nr_Triads:			the number of triads presented (default: 30)

expressions.numberCorrect:		number of correctly solved triads
expressions.propSolved:			proportion correctly solved triads
expressions.meanRT:				mean correct latency (in ms) for solved triads
expressions.SD:					standard deviation of correct latencies

expressions.numberCorrect_easy:		number of correctly solved 'easy' triads
expressions.propSolved_easy:		proportion correctly solved 'easy' triads
expressions.meanRT_easy:			mean correct latency (in ms) for solved 'easy' triads
expressions.SD_easy:					standard deviation of correct latencies for solved 'easy' triads

expressions.numberCorrect_medium:	number of correctly solved 'medium' triads
expressions.propSolved_medium:		proportion correctly solved 'medium' triads
expressions.meanRT_medium:			mean correct latency (in ms) for solved 'medium' triads
expressions.SD_medium:				standard deviation of correct latencies for solved 'medium' triads

expressions.numberCorrect_hard:		number of correctly solved 'hard' triads
expressions.propSolved_hard:		proportion correctly solved 'hard' triads
expressions.meanRT_hard:			mean correct latency (in ms) for solved 'hard' triads
expressions.SD_hard:				standard deviation of correct latencies for solved 'hard' triads

"DATA" and follow further instructions

EXPERIMENTAL SET-UP 
___________________________________________________________________________________________________________________	
- 30 triads are presented one by one

- 10 triads are categorized as "easy", 10 triads are categorized as "medium", 10 triads are categorized as "hard"
Categorization (Bowden & Jung-Beeman, 2003 - Appendix):
easy: proportion of participants solving triad (at 15s) > 0.75
medium: 0.45 < proportion of participants solving triad (at 15s) < 0.55
hard: proportion of participant solving triad (at 15s) < 0.25

- the order of the triads is determined randomly for each participant (by default - 
can be edited under section Editable Lists)

___________________________________________________________________________________________________________________	
STIMULI
___________________________________________________________________________________________________________________	
- triads are selected from Bowden & Jung-Beeman (2003), Appendix
- triads can be replaced under section "Editable Stimuli"

INSTRUCTIONS 
___________________________________________________________________________________________________________________	
Instructions are not original to the task. They are provided by Millisecond Software
as htm/html pages and can be edited by changing the provided htm/html files.
To edit htm/html-files: open the respective documents in simple Text Editors such as TextEdit (Mac)
or Notepad (Windows).

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:

/maxResponseWindow:			the maximum time (in ms) allowed for each item
/nr_triads:					the number of triads presented (default: 30)

/debugmode:					1 = script runs in debug mode (presents solutions); 0 = otherwise
