TASK DESCRIPTION	
___________________________________________________________________________________________________________________	

subtest5: AFFECT DISCRIMINATION

Participants are presented one face at a time (6 altogether) and have to identify the emotion of the face
(i.e., Happy, Sad, Angry, Frightened, Surprised, Disgusted, or Neutral)

___________________________________________________________________________________________________________________	
DURATION 
___________________________________________________________________________________________________________________	
the default set-up of the script takes appr. 2 minutes to complete

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

(1) Raw data file: 'catsr_subtest5_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

subtest:							"subtest5"									

//if the subtest is run via a batch script that collects gender/age/taskOrder information:									
age:								the age of the participant 								
gender:								Female; Male; Other
taskOrder:							the selected task order		

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. 
										
/trialCount:						trial counter																				
/subtest5_testitem:					the index of the selected image 
/testitem:							the presented image

/correctResponse:					the dedicated correct response: 
									1 = happy
									2 = sad
									3 = angry
									4 = neutral
									5 = frightened
									6 = surprised
									7 = disgusted									
									
/selectedResponse:					happy, sad, angry, neutral, frightened, surprised, disgusted

correct:							accuracy of response: 1 = correct response; 0 = otherwise					 
/RT:								cumulative response latency: measured from onset of image until 'nextButton' is pressed


(2) Summary data file: 'catsr_subtest5_summary*.iqdat' (a separate file for each participant)*

inquisit.build:						the Inquisit build/version run
computer.platform:					the platform the script was run on (win/mac/ios/android)
inquisit.build:						the version/build of Inquisit
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)
									
subtest:							"subtest5"									

//if the subtest is run via a batch script that collects gender/age/taskOrder information:									
age:								the age of the participant 								
gender:								Female; Male; Other
taskOrder:							the selected task order								
																	
									
T5_rawscore:					the number of correct responses in subtest5	
T5_rawscore_corrected:			the number of correct responses in subtest5, corrected
								(Note: in this subtest rawscores get corrected for Male Participants over the age of 59 by +1 to rawscore)
								
T5_zscore:						the z-score for the corrected T5_rawscore	
								(z-scores get calculated based on overall Mean and standard deviation)
									
T5_propCorrect:					proportion correct responses in subtest5
T5_RT:							mean response time (in ms) in subtest5; measured from onset of image until 'nextButton' is pressed									
T5_corrRT:						mean response time (in ms) of CORRECT responses in subtest5; measured from onset of image until 'nextButton' is pressed							

+ results from individual questions
							
* 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 
___________________________________________________________________________________________________________________	

1 Testblock of 12 trials
- 6 trials with emotions: happy, sad, angry, frightenend, surprised, disgusted (no neutral face presented)
The order of the images is predetermined.

Participants can select from 7 emotion buttons. Responses can be changed until 'next' is pressed.
If button 'repeat' is pressed, nothing happens in this script as the images are still on screen.

Note: By setting parameters.showAdvanceButton to true, a '?'-button appears in the upper right corner.
If pressed, the next scheduled test item is skipped.
