BACKGROUND INFO 	
___________________________________________________________________________________________________________________

This script implements the Baddeley's 3-Minute Grammatical Deductive Reasoning Test
described in:

Baddeley, A. D. (1968). A 3 min reasoning test based on grammatical transformation. 
Psychonomic Science, 10, 341-342.

TASK DESCRIPTION	
___________________________________________________________________________________________________________________
Participants view statements like "A follows B" paired with 2 letters "AB" or "BA" and are asked
to judge whether the letter pair is a correct representation of the statement by clicking
"true" or "false". The test times out after 3 minutes.

___________________________________________________________________________________________________________________	
DURATION 
___________________________________________________________________________________________________________________	
the default set-up of the script takes appr. 4 minutes to complete

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

(1) Raw data file: 'baddeley_german_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.

stimulusitem:						the presented stimuli in order of trial presentation
response:							the participant's response ('true' or 'false')
correct:							accuracy of response: 1 = correct response; 0 = otherwise
latency: 							the response latency (in ms); measured from: onset of problem
totalnumcorrect: 				total correct responses tallied separately for practice and test trials


(2) Summary data file: 'baddeley_german_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)
								
totalnumcorrect:				total number of correct test responses


___________________________________________________________________________________________________________________	
EXPERIMENTAL SET-UP 
___________________________________________________________________________________________________________________
- 64 statements (half of them are 'true') tested in 3 minutes
- order of statements random
	
PRACTICE 
- 4 practice statements

___________________________________________________________________________________________________________________	
STIMULI
___________________________________________________________________________________________________________________
- 64 statements: 2 phrasing (positive vs negative) x 2 activeness (active vs passive) x 2 Correctness (true vs false) x 2 order (precedes vs. follows) x 2 first letter mentioned in statement (A or B) vs. 2 letter pairs (AB vs BA)

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:

/testduration:			sets the duration of the test in ms (default: 3min => 180000ms)
