BACKGROUND INFO

											*Purpose*
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*
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.



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:							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 
/colorcondition:				1 = greenpurple; 2 = orangeblue
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
/correctoption:					stores the correct option (1-4: from left to right)
latency: 						the response latency (in ms)
response:						the participant's response
correct:						the correctness of the response (1 = correct; 0 = incorrect)
/responsecategory:				C=correct; E = Extension; D = Distortion; T = Triangle
/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)

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)
/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 assignment to color condition is counterbalanced by groupnumber.

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 slides.
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
