BACKGROUND INFO

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


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)

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)

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
