BACKGROUND INFO

											*Purpose*
This script implements the Self-Esteem Conditioning Task described in:

Baccus J.R., Baldwin M.W., & Packer D.J. (2004). Increasing Implicit Self-Esteem Through Classical Conditioning.
Psychological Science, 15(7), 498-502.

											  *Task*
Participants see a 2x2 matrix. In one of the 4 cells a word is displayed, belonging either to the 'self' or
'no-self' category. Participants are asked to click on the words as fast as possible.
Upon selection of the word, the word is replaced by either a happy, a frowny or a neutral 
face picture for the duration of 400ms (default).


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

(1) Raw data file: 'SelfEsteemConditioning_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 
/condition:						"experimental", "control"
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) 
/stimx-stimy:					x/y coordinates of the stimulus
stimulusitem:					the presented stimuli in order of trial presentation
response:						the participant's response
latency: 						the response latency (in ms)
/meanlat_experimental: 			mean response latency (in ms) in experimental condition
/meanlat_control:				mean response latency (in ms) in control condition

(2) Summary data file: 'SelfEsteemConditioning_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)
/condition:						"experimental", "control"
/meanlat_experimental: 			mean response latency (in ms) in experimental condition
/meanlat_control:				mean response latency (in ms) in control condition
/avgspeed:						mean response latency in s

EXPERIMENTAL SET-UP
2 groups: experimental vs. control (assignment by groupnumber)

Experimental: 240 trials total (order is randomized)
- 80 trials: pairings of 'self' words with smiley faces (self words selected with replacement)
- 80 trials: pairings of 'no-self' words with frowny faces (no-self words selected with replacement)
- 80 trials: pairings of 'no-self' words with neutral faces (no-self words selected with replacement)

Note: quadrant position is sampled randomly with replacement

Control: 240 trials total (order is randomized)
- 80 trials: pairings of 'self' with either a smiley, a frowny or a neutral face (self words selected with replacement)
- 160 trials: pairings of 'no self' with either a smiley, a frowny or a neutral face (no-self words selected with replacement)
Across the 240 trials: facial expressions are selected randomly without replacement
(=> 80 trials per facial expression)

The face images are presented for 400ms (default) -> change under section Editable Parameters

STIMULI
see section Editable Stimuli

INSTRUCTIONS
see 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:

/picduration:				the presentation duration of the face pics in ms (default: 400ms)
