BACKGROUND INFO 	
___________________________________________________________________________________________________________________
This script implements the Number Series Task, a measure of pattern recognition/inductive reasoning 
and fluid intelligence.

The implemented procedure is based on:

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.

TASK DESCRIPTION	
___________________________________________________________________________________________________________________
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. 


___________________________________________________________________________________________________________________	
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: 'numberseries_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. 
										
									
parameters.taskduration:			time alloted to the entire task (default: 270000ms = 4.5min)									
									
stimulusitem.1-
stimulusitem.3					the presented stimuli in order of trial presentation

values.choice1-
values.choice5: 					contain the stimuli for the 5 choices

values.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)
values.numcorrect:				sum up all correct responses 

(2) Summary data file: 'numberseries_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.taskduration:			time alloted to the entire task in ms (default: 270000ms = 4.5min)
values.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)
