This script implements the Rey Visual Design Learning Test (RVDLT), an assessment tool for immediate/delayed and recognition memory for non-verbal items.
The implemented procedure is based on: 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
15 minutes
Participants are presented 15 simple figures. Each figure is presented for 2s (default). Afterwards recall (immediate/delayed) and recognition tests are given.
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
(a screenshot of the drawn figures will be produced and stored for later analysis)
- 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
see section Editable Stimuli
(stimuli are reproduced based on the info published in: Wilhelm (2004)
Instructions are not original to the task. They are provided by Millisecond
as htm/html pages and can be edited by changing the provided htm/html files.
To edit htm/html-files: open the respective documents in simple Text Editors such as TextEdit (Mac)
