BACKGROUND INFO 	
___________________________________________________________________________________________________________________	
This script implements a computerized version of the "Reading the Mind in Films Task" (Child Version) by
Golan et al (2008). The Task provides a measure of complex emotion recognition in children.

TASK DESCRIPTION
___________________________________________________________________________________________________________________	

Participants view 22 film clips (+ 1 practice) and are asked to select one of 4 possible adjectives to describe the
emotion of one of the characters. 

___________________________________________________________________________________________________________________	
DURATION 
___________________________________________________________________________________________________________________	
the default set-up of the script takes appr. 15 minutes to complete

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

(1) Raw data file: 'readingnindinfilm_child_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. 
										
values.movie:						stores the movie currently presented										
stimulusitem.1-4:					the presented stimuli in order of trial presentation
values.correctResponse: 			stores the correct response (A-D)
response:							the participant's response (A-D)
correct:							accuracy of response: 1 = correct response; 0 = otherwise
latency: 							the response latency (in ms); measured from: offset of movie

(2) Summary data file: 'readingnindinfilm_child_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)
									
expressions.propCorrect:			proportion correct selections
expressions.meanRT:					mean latency (in ms) of correct selections
expressions.SD_RT:					standard deviation (in ms) of correct selection latencies

* separate data files: to change to one data file for all participants (on Inquisit Lab only), go to section
"DATA" and follow further instructions

EXPERIMENTAL SET-UP 
___________________________________________________________________________________________________________________	
* 24 short film clips (+ 1 practice clip)
-> order of films is the same for each participant (sequential sampling)
* Trial Sequence:
a) presentation of next target question + answer choices (continues upon Spacebar press)
b) presentation of film (+ presentation of target question + answer choices) (continues once movie ends)
c) Response collection via mouse click (optional definition handout presented on screen -> see Editable Parameters)
Note: Definition Handout (of the adjectives) provided with this script

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:

/showDefinitionHandout:			true: the Definition Handout is automatically presented as an htm-stimulus on screen anytime participants are asked to select a word
								false: no Definition Handout is automatically presented (default)
								Note: an Excel file of the Definition Handout by https://www.autismresearchcentre.com/arc_tests is provided with the script

/iti:							intertrial interval in ms (default: 500)
