BACKGROUND INFO 	
___________________________________________________________________________________________________________________	

This script implements a computerized version of the Ten Item Personality Inventory (TIPI) described in:

Gosling, S. D., Rentfrow, P. J., & Swann, W. B. Jr. (2003). A very brief measure of the Big-Five personality domains.
Journal of Research in Personality, 37, 504–528. 

___________________________________________________________________________________________________________________
OVERVIEW
___________________________________________________________________________________________________________________	

10 7-point Likert questions: 2 for each of the 5 personality domains 
(Extraversion, Agreeableness, Conscientiousness, Emotional Stability, Openeness)

___________________________________________________________________________________________________________________	
DURATION 
___________________________________________________________________________________________________________________	
the default set-up of the script takes less than 1 minute

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

(1) Raw data file: 'tipi.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 (disagree strongly) - 7 (agree strongly)
									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: 'tipi_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)


Range: 1-7 => the higher the score the higher the particular facet has been affirmed by participant 
								
expressions.Extraversion:					mean Extraversion score
expressions.Agreeableness:					mean Agreeableness score
expressions.Conscientiousness:				mean Conscientiousness score
expressions.EmotionalStability:				mean Emotional Stability score
expressions.Openeness:						mean Openeness score

Norms:

parameters.calculateGenderPercentile:	true (1) = z-score and percentiles are calculated based on gender norms (provided by Gosling et al, 2003, p.526) - can be set under Editable Parameters
												false (0) = z-score and percentiles are calculated using the overall norms (provided by Gosling et al, 2003, p.526)

radiobuttons.gender.response:				1 = female; 2 = male; empty (=> question wasn't asked)
								
/z_E:							calculated z-score of the Extraversion score (based on data provided by Gosling et al, 2003, p.526)
/E_percentile:					z-score percentile of the Extraversion score (based on data provided by Gosling et al, 2003, p.526)
/z_A:							calculated z-score of the Agreeableness score (based on data provided by Gosling et al, 2003, p.526)
/A_percentile:					z-score percentile of the Agreeableness score (based on data provided by Gosling et al, 2003, p.526)
/z_C:							calculated z-score of the Conscientiousness score (based on data provided by Gosling et al, 2003, p.526)
/C_percentile:					z-score percentile of the Conscientiousness score (based on data provided by Gosling et al, 2003, p.526)
/z_ES:							calculated z-score of the Emotional Stability score (based on data provided by Gosling et al, 2003, p.526)
/ES_percentile:				z-score percentile of the Emotional Stability score (based on data provided by Gosling et al, 2003, p.526)
/z_O:							calculated z-score of the Openeness score (based on data provided by Gosling et al, 2003, p.526)
/O_percentile:					z-score percentile of the Openeness score (based on data provided by Gosling et al, 2003, p.526)

QUESTIONNAIRE SET-UP & SCORING
___________________________________________________________________________________________________________________

10 7-point Likert questions
- 2 for each of the 5 personality domains (Extraversion, Agreeableness, Conscientiousness, Emotional Stability, Openeness)
- one of the two questions is reversed scored (automatically done by the program)
- if parameters.calculateGenderPercentile is set to 'true', a gender question is provided at the end of the questionnaire
(by default, the gender question is omitted)

Scoring:
* computer automatically calculates the average score for the 5 categories
* computer automatically calculates the z-score and percentile values of the 5 scores based on data published by
Gosling et al (2003)
-> by default, overall means across gender and ethnic groups are used
-> if parameters.calculateGenderPercentile is set to 'true', percentiles are calculated based on the reported gender
(across ethnic groups)

INSTRUCTIONS 
___________________________________________________________________________________________________________________	
slightly adapted from Gosling et al (2003) to reflect a different testing setup.

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 posted on top of each page of the questionnaire

/calculateGenderPercentile:		true (1) = z-score and percentiles are calculated based on gender norms (provided by Gosling et al, 2003)
								false (0) = z-score and percentiles are calculated using the overall norms (provided by Gosling et al, 2003) 
								(default)
