BACKGROUND INFO

											*Purpose*
This script implements the Number Series Task as used in:

Redick, T.S., Shipstead, Z., Fried, D.E., Hambrick, D.Z., Kane, M.J. & Engle, R.W. (2012).
No Evidence of Intelligence Improvement After Working Memory Training: A Randomized, Placebo-Controlled Study.
Journal of Experimental Psychology: General, 1-21.

											  *Task*
Participants work on 5 number series questions within a specified time frame (default: 4.5min).
The number series questions are multiple choice with 5 answer choices. 
											 

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

(1) Raw data file: 'NumberSeries_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 
/taskduration:					time alloted to the entire task (default: 270000ms = 4.5min)
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) 
stimulusitem:					the presented stimuli in order of trial presentation
/choice1-choice5: 				contain the stimuli for the 5 choices
/correctchoice:					contains the index of the correct choice for each target
response:						the participant's response
correct:						the correctness of the response (1 = correct; 0 = incorrect)
latency: 						the response latency (in ms)
/numcorrect:				 	sum up all correct responses 

(2) Summary data file: 'NumberSeries_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)
/taskduration:					time alloted to the entire task in ms (default: 270000ms = 4.5min)
/numcorrect:				 	sum up all correct responses 


EXPERIMENTAL SET-UP
The script presents 5 number series trials (block.numberseries)
Each trial presents a target number series and 5 answer choices. After participants select their choice via mouse-click,
the selection gets briefly highlighted before the next trial starts.

There are 5 practice problems before the actual test starts.

Timer:
There are 4.5 min allotted to finish block.numberseries (default, can be changed under
VALUES -> EDITABLE PARAMETERS). A clock on the screen counts down the min/s for the participants.
60s (default, can be changed under VALUES -> EDITABLE PARAMETERS) before the 4.5 min are up,
a red circle appears around the clock to highlight the remaining time.

STIMULI
Stimuli  can be edited under section Editable STIMULI 

INSTRUCTIONS
Instructions can be edited 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:

/taskduration:					time alloted to the entire task in ms (default: 270000ms = 4.5min)
/timereminder: 					a red circle appears around the clock at this time to highlight how much time is left in ms (default: 60000ms = 1min left)
