BACKGROUND INFO 	
___________________________________________________________________________________________________________________	
This script demonstrates a task in which subjects attempt to identify words presented peripherally as 
they stare at a fixation point in the center of the screen. 
The eye tracker is used to ensure subjects are looking at the fixation point for 250ms when the target word 
is presented.

TASK DESCRIPTION	
___________________________________________________________________________________________________________________	
Participants are presented subliminal words for 1 vertical refreshate (~17ms on 60Hz monitor) and are asked
to type them into a textbox.											

___________________________________________________________________________________________________________________	
DURATION 
___________________________________________________________________________________________________________________	
the default set-up of the script takes appr. 5 minutes to complete

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

(1) generic Inquisit raw data file: 'parafoveal_raw*.iqdat'

(2) Summary data file: 'parafoveal_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)

EXPERIMENTAL SET-UP 
___________________________________________________________________________________________________________________	
1 Block of 50 trials:
a) Fixation Point for at least 250ms (once participants focus on fixation point after 250ms, the trial continues)
b) Word Presentation for 1 vertical refreshrate (on 60Hz monitor: ~17ms); then openended textbox
