BACKGROUND INFO 

											*Purpose*
This script implements the Rey Visual Design Learning Test (RVDLT) as described in: 
P. Wilhelm (2004). Reliability and Validity of the Rey Visual Design Learning
Test in Primary School Children, Journal of Clinical and Experimental Neuropsychology, 26:7,
981-994, DOI: 10.1080/13803390490511076


The RVDLT is an assessment tool for immediate/delayed and recognition memory for non-verbal items.


											  *Task*
Participants are presented 15 simple figures. Each figure is presented for 2s (default).
Afterwards recall (immediate/delayed) and recognition tests are given.
											  
											  
DATA FILE INFORMATION: 
The default data stored in the data files are:

(1) Raw data file: 'ReyVisualLearningTest_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
/SessionNr:						stores the recall iteration (1 to 3: immediate recall; 4 = delayed; 5 = recognition)
/recallType:					"immediate" vs. "delayed"
/recallCountPic:				stores the number of the recalled image
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:						the correctness of the response (1 = correct; 0 = incorrect)
latency: 						the response latency (in ms)
/recognitionSelections:			stores all selected images in the Recognition Task


(2) Summary data file: 'ReyVisualLearningTest_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)
/Recognition_numberSelected:	retrieves the number of selected items in the Recognition Task
/Recognition_hitRate:			calculates the hit rate in the Recognition Task
/Recognition_faRate:			calculates the false alarm rate in the Recognition Task
/recognitionSelections:			stores all selected images in the Recognition Task


EXPERIMENTAL SET-UP
5 blocks (to change the order of blocks or add/subtract blocks from the default procedure, go to section Experiment)

3 repeats: Figure Presentations (each figure is presented for 2s) -> Immediate Recall Session (on Inquisit Lab, a screenShot of the drawn figures is stored on the computer)
- the order of the figures is predetermined and the same for each participant (see picture.testFigure)
- recall task terminates after 15 figures have been collected
1: Delayed Recall Session
1: Recognition Task: 
- presents a 5x6 matrix of 15 old and 15 new figures (matrix location is randomly assigned for each participant)
- participants are asked to select all the figures they remember
- once a figure is selected, it gets erased from the matrix
- task terminates after 15 figures have been selected

!Note: a screenshot of the reproduced/recalled items is saved automatically on Inquisit Lab only


STIMULI
see section Editable Stimuli
(stimuli are reproduced based on the info published in: Wilhelm (2004)

INSTRUCTIONS
Instructions are not original. They 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:

/stimPresentation:			figure presentation duration in ms (default: 2000)
/picSize:					size of figure image in canvas screen percentages (default: 40%)
/delay:						delay duration in ms before delayed recall (default: 60000)
