BACKGROUND INFO 	
___________________________________________________________________________________________________________________	
This script implements a Sentence Completion Task (SCT). SCT are general instruments to study
information processing and can be used to study - amongst others- cognitive priming effects, 
semantic bias, and autobiographical memory.

The implemented procedure uses the study of autobiographical memory as an example.
It is based on:

Raes, F., Hermans, D., Williams, J.M.G. & Eelen, P. (2007). A sentence completion procedure as an alternative to the 
Autobiographical Memory Test for assessing overgeneral memory in non-clinical populations.  Memory, 15, 495-507.

TASK DESCRIPTION
___________________________________________________________________________________________________________________
Participants are given 11 sentence completion tasks (11 Stems) to complete. Afterwards they are asked
to categorize their own responses into several categories.

___________________________________________________________________________________________________________________	
DURATION 
___________________________________________________________________________________________________________________	
the default set-up of the script takes appr. 7 minutes to complete

___________________________________________________________________________________________________________________	
DATA FILE INFORMATION 
___________________________________________________________________________________________________________________	

This script generates 3 data files:
- SentenceCompletionTask.iqdat => raw data of sentence completion task
- SentenceCompletionTask_Rating.iqdat => raw data of response categorizations
- SentenceCompletionTask_summary.iqdat => summary file that contains responses to SCT task AND categorization task

(1) Raw data file: 'sentencecompletiontask.iqdat.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
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) Raw data file: 'sentencecompletiontask_rating.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: 1-8)
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)

(3) Summary data file: 'sentencecompletiontask_summary*.iqdat' (a separate file for each 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)
									
textbox.Stem1.response-
textbox.Stem11.response:			the responses to the 11 Stem qu
estions
radiobuttons.Rating1.response-
radiobuttons.Rating11.response:	the individual ratings (1-8)

EXPERIMENTAL SET-UP 
___________________________________________________________________________________________________________________

2 surveys:
SentenceCompletionTask: 11 sentence completion task with default Stems (see section Editable Parameters)
Ratings (optional): Participant categorization of the responses 

___________________________________________________________________________________________________________________	
INSTRUCTIONS 
___________________________________________________________________________________________________________________
see section Editable Parameters

___________________________________________________________________________________________________________________	
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:

/stem1-stem11:						the particular Stems used in this script
/instructions:						the instructions to appear with the Stem questions

/participant_responserating:    	1 = participants are asked to categorize their sentences (default)
									Note: to change the response categories go to RATING QUESTIONS
									and change the setting OPTIONS for each question
									0 = participants are not asked to categorize their sentences
