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

(1) Raw data file: 'bidr.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:						scores given for response selected (in assigned values: 0-1) - reversed items are automatically reversed scored
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: 'bidr_summary.iqdat' (Inquisit Lab: one data file per 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)

BIDR_total:						total score for the BIDR (0-40)
									=> the higher the score the more questions were answered with a
