BACKGROUND INFO 	
___________________________________________________________________________________________________________________	
Script implements the Synonym Antonym Task as used in:

Salthouse, T.A., Atkinson, T.M, & Berish, D.E. (2003).Executive Functioning as a Potential Mediator of 
Age-Related Cognitive Decline in Normal Adults. Journal of Experimental Psychology: General, 132, 566–594.

___________________________________________________________________________________________________________________
TASK DESCRIPTION	
___________________________________________________________________________________________________________________	
Participant is presented with a target word and needs to select from among 5 choices the word 
a) that has the closest meaning to the target word (Synonym Task)  or
b) that has the opposite meaning of the target word (Antonym Task)
Selection is done via mouse-click.

___________________________________________________________________________________________________________________	
DURATION 
___________________________________________________________________________________________________________________	
This is a timed task. The default set-up allows 5 minutes.

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

(1) Raw data file: 'synonymantonym_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: 300000ms = 5min)
																				
Presented Stim1:					the presented stimuli in order of trial presentation
Presented Stim2:					= presented word
values.choice1-Choice5: 			contains the stimulus 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_syn-
values.numcorrect_ant:	 		sum up all correct responses for Synonyms/Antonyms
values.total_correct:				sum of all correct responses


(2) Summary data file: 'synonymantonym_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 (default: 300000ms = 5min)

values.numcorrect_syn-
values.numcorrect_ant:	 		sum up all correct responses for Synonyms/Antonyms
values.total_correct:				sum of all correct responses

EXPERIMENTAL SET-UP 
___________________________________________________________________________________________________________________	
The script presents 10 synonym trials (block.synonymtask) before moving on to 10 antonym trials (block.antonymtask).
Each trial presents a target and 5 word choices. After participants select their choice via mouse-click,
the selection gets briefly highlighted before the next trial starts.

Timer:
There are 5 min allotted to finish block.synonym AND block.antonym (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 5 min are up,
a red circle appears around the clock to highlight the remaining time.

___________________________________________________________________________________________________________________	
STIMULI
___________________________________________________________________________________________________________________

Stimuli  can be edited under 
EDITABLE STIMULI -> synonym stimuli -> item.synonym and STIMULI -> antonym stimuli -> item.antonym

___________________________________________________________________________________________________________________	
INSTRUCTIONS 
___________________________________________________________________________________________________________________

Instructions are not original to the task. They are provided by Millisecond Software
as htm/html pages and can be edited by changing the provided htm/html files.
To edit htm/html-files: open the respective documents in simple Text Editors such as TextEdit (Mac)
or Notepad (Windows).	

___________________________________________________________________________________________________________________	
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: 300000ms = 5min)
/timereminder: 		a red circle appears around the clock at this time (in ms) )to highlight how much time is left (default: 60000ms = 1min left)
