BACKGROUND INFO 	
___________________________________________________________________________________________________________________	
This script implements a computerized version of the Mental Folding Test for Children (MFTC) published by:

Harris, J., Hirsh-Pasek, K. & Newcombe, N. S. (2013). A new twist on studying the development of dynamic 
spatial transformations: Mental paper folding in young children. Mind, Brain and Education, 7, 49-55.
			
(see also: http://spatiallearning.org/index.php/testsainstruments)

Suggested Age Group: 4-7

___________________________________________________________________________________________________________________
TASK DESCRIPTION	
___________________________________________________________________________________________________________________	
Participants are asked to mentally fold paper following specific markings and then select 
from amongst 4 options the one that represents the outcome of the mental folding.

___________________________________________________________________________________________________________________	
DURATION 
___________________________________________________________________________________________________________________	
the default set-up of the script takes appr. 8 minutes to complete

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

(1) Raw data file: 'mentalpaperfolding_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. 
									
parameters.colorCondition:	1 = green/purple
							2 = orange/blue
																				
stimulusitem.1:				the current test image (to mentally fold)																		
stimulusitem.2-				the four presented solution images from left to right
stimulusitem.5:				

option1category-: 			C(orrect), E(xtension), D(istortion), or T(riangle)
option4category

response:					the participant's response (option1-option4)
responsecategory:			C=correct; E = Extension; D = Distortion; T = Triangle
correctoption:				stores the correct option (1-4: from left to right)
correct:					the correctness of the response (1 = correct; 0 = incorrect)
latency: 					the response latency (in ms)

count_C:					counts all correct responses
count_E:					counts all extension responses
count_D:					counts all distortion responses
count_T:					counts all triangle responses


(2) Summary data file: 'mentalpaperfolding_summary*.iqdat' (a separate file for each participant)

inquisit.version:				Inquisit version run
computer.platform:				the platform the script was run on (win/mac/ios/android)
startdate:						date script was run
starttime:						time script was started
subjectid:						assigned subject id number
groupid:						assigned group id number
sessionid:						assigned session id number
elapsedtime:					time it took to run script (in ms); measured from onset to offset of script
completed:						0 = script was not completed (prematurely aborted); 
								1 = script was completed (all conditions run)

count_C:						counts all correct responses
count_E:						counts all extension responses
count_D:						counts all distortion responses
count_T:						counts all triangle responses
propC:							proportion correct responses
propE:							proportion of extrension error responses (based on all problems)
propD:							proportion of distension error responses (based on all problems)
propT:							proportion of triangle error responses (based on all problems)

EXPERIMENTAL SET-UP 
___________________________________________________________________________________________________________________	

(1) Practice: 2 practice items
Practice Item 1 is also discussed during instructions with the help of the test administrator.
The practice problems are repeated until child selects the correct response.
(2) Test: 14 test problems (no feedback should be given)
Each prompt is presented with 4 response options.
Each response option is categorized as either C(orrect), E(xtension), D(istortion), or T(riangle)

___________________________________________________________________________________________________________________
STIMULI
___________________________________________________________________________________________________________________
Stimuli are the original green-purple stimuli provided at
http://spatiallearning.org/index.php/testsainstruments
A second set in orange-blue was generated by Millisecond Software.
The set selection is controlled via an editable parameter (parameters.colorCondition)

___________________________________________________________________________________________________________________	
INSTRUCTIONS 
___________________________________________________________________________________________________________________	
Harris et al (2013) use actual paper models of the prompts and have the kids fold the models to train for
practice item #1.
The instructions used by Harris et al (2013) can be obtained from the authors or at
http://spatiallearning.org/index.php/testsainstruments.

The instructions provided in this script by Millisecond Software are written for the computer and presented in 
form of htm-slides using scalable vector images (*.svg)
It is assumed that a test administrator works with the child while presenting them.
The slides can be edited/exchanged under EDITABLE CODE -> Editable Instructions.
The instruction block is optional. It can be skipped (see Editable Values); if they are skipped
the script jumps right into the first practice problem.

___________________________________________________________________________________________________________________	
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:

/skipinstructionblock:				true = instruction block is skipped
								false = instruction block is run (default)
									
/iti:								intertrial interval is ms between selecting a response and the presentation of the next prompt

/colorCondition:					1 = runs the green/purple set
								2 = runs the orange/blue set
