___________________________________________________________________________________________________________________	
14 4-point Likert scale items (when scored the scale gets simplified into binary categories); self-report

___________________________________________________________________________________________________________________	
DURATION 
___________________________________________________________________________________________________________________	
the default set-up of the script takes appr. 1.5 minutes to complete

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

(1) Raw data file: 'shaps.iqdat'

date, time:						date and time script was run with the current group/subjectnumber 
subject, group, session:	  	with the current subject/groupnumber/session id
build:							the Inquisit build 

q*_response:					response given (in assigned values)
								4 = strongly disagree, 3 = disagree, 2 = agree, 1 = strongly agree
								'D' => questions with a slightly different scale
								1 = "Definitely Agree", 2 = "Agree", 3 = "Disagree", 4 = "Strongly Disagree"
								
q*_latency:						how much time (in ms) the participant spent on the surveypage with this particular question (the last time this particular surveypage was visited)


(2) Summary data file: 'shaps_summary.iqdat' (Inquisit Lab: one data file per participant)

inquisit.version:				Inquisit version run
computer.platform:				the platform the script was run on (win/mac/ios/android)
startdate:						date script was run
starttime:						time script was started

groupid:						assigned group id number
sessionid:						assigned session id number
