BACKGROUND INFO 

											*Purpose*
This script implements a simple picture rating script that uses the Self Assessment Manikin Pictorial Rating Scale
described in:

Bradley, M. & Lang, P.J. (1994). Measuring Emotion: The Self-Assessment Manikin and The Semantic
Differential. J. Behav. Ther. Exp. Psychiat, 25, 49-59.


											  *Task*
Participants are shown 8 pictures (one at a time) and are asked to rate the emotions these pictures elicit
on three dimensions: valence, arousal, dominance.
The rating scales consist of a series of pictorial depictions of a manikin displaying those emotions.



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

(1) Raw data file: 'selfassessmentmanikin_raw*.iqdat' (a separate file for each participant)*

build:							Inquisit build
computer.platform:				the platform the script was run on
date, time, subject, group:		date and time script was run with the current subject/groupnumber 
blockcode, blocknum:			the name and number of the current block
trialcode, trialnum: 			the name and number of the currently recorded trial
									(Note: not all trials that are run might record data; by default data is collected unless /recorddata = false is set for a particular trial/block) 
stimulusitem:					the presented stimuli in order of trial presentation
response:						the participant's response
correct:						accuracy of response: 1 = correct response; 0 = otherwise
latency: 						the response latency (in ms); measured from:

(2) Summary data file: 'selfassessmentmanikin_summary*.iqdat' (a separate file for each participant)*

script.startdate:				date script was run
script.starttime:				time script was started
script.subjectid:				subject id number
script.groupid:					group id number
script.elapsedtime:				time it took to run script (in ms)
computer.platform:				the platform the script was run on
/completed:						0 = script was not completed (prematurely aborted); 1 = script was completed (all conditions run)


* separate data files: to change to one data file for all participants (on Inquisit Lab only), go to section
"DATA" and follow further instructions


EXPERIMENTAL SET-UP

This script implements a simple demonstration to use the Self Assessment Manikin Scales for picture ratings.
* 8 trials (the order of the images is determined randomly)
* participants need to select one of the response boxes for each of the three dimensions (valence, arousal, dominance)
