BACKGROUND INFO 

											*Purpose*
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.

Bowden, E.M., & Jung-Beeman, M. (2003). Normative data for 144 compound remote associate problems. 
Behavioral Research Methods, Instrumentation, and Computers, 35, 634-639.


											  *Task*
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 1minute.
  


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:							Inquisit build
computer.platform:				the platform the script was run on
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; by default data is collected unless /recorddata = false is set for a particular trial/block) 
/triadCount:					counts the triads
stimulusitem:					the presented triad
/solution:						stores the solution for the current triad
/difficulty:					stores the difficulty 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)*

script.startdate:				date script was run
script.starttime:				time script was started
script.subjectid:				subject id number
script.groupid:					group id number
script.elapsedtime:				time it took to run script (in ms)
computer.platform:				the platform the script was run on
/completed:						0 = script was not completed (prematurely aborted); 1 = script was completed (all conditions run)
/maxResponseWindow:				the maximum time (in ms) allowed for each item
/nr_Triads:						the number of triads presented (default: 30)

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

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

/propSolved_medium:				proportion correctly solved 'medium' triads
/numberCorrect_medium:			number of correctly solved 'medium' triads
/meanRT_easy:					mean correct latency (in ms) for solved 'medium' triads
/SD_easy:						standard deviation of correct latencies for solved 'medium' triads

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

* 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
- 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 provided by Millisecond Software as an htm-page.
Changes can be made to the file "art_intro_itembyitem.htm" directly.

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:

/maxResponseWindow:				the maximum time (in ms) allowed for each item
/nr_triads:						the number of triads presented (default: 30)
/debug:							1 = script runs in debug mode (presents solutions); 0 = otherwise
