BACKGROUND INFO 	
___________________________________________________________________________________________________________________
This script implements a computerized version of the 'Santa Barbara Sense of Direction Scale'
as described in:

Hegarty, M. Richardson, A. E., Montello, D. R., Lovelace, K & Subbiah, I. (2002). 
Development of a Self-Report Measure of Environmental Spatial Ability. Intelligence, 30, 425-447.

OVERVIEW
___________________________________________________________________________________________________________________
15 7-point Likert Scale questions on sense of direction (self-report)

___________________________________________________________________________________________________________________	
DURATION 
___________________________________________________________________________________________________________________	
the default set-up of the script takes appr. 2 minutes to complete

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

(1) Raw data file: 'senseofdirectionsurvey.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)
									Scale: 1 (strongly agree)-7 (strongly disagree)
									R = automatically reversed scored questions
									
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: 'senseofdirectionsurvey_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)

expressions.SODtotal:				sum of all 15 scores (reversed scoring automatically applied)

QUESTIONNAIRE SET-UP & SCORING
___________________________________________________________________________________________________________________	

15 questions: 7 point Likert Scales
2, 6, 8, 10, 11, 12, 13, 15: strongly agree = 1 - strongly disagree = 7
1R, 3R, 4R, 5R, 7R, 9R, 14R: strongly agree = 7 - strongly disagree = 1
=> higher rating indicates a better self-report SOD

INSTRUCTIONS 
___________________________________________________________________________________________________________________
minimally altered (=>to reflect the computerized input modality) original instructions;
can be edited under section Editable Instructions

___________________________________________________________________________________________________________________	
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:

/pageinstructions:			the instructions that appear at the top of each surveypage
/pageinstructions2:		the instructions that appear at the top of each surveypage
