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 __________________________________________________________________________________________________________________ TASK DESCRIPTION ___________________________________________________________________________________________________________________ Participants are presented 15 simple figures. Each figure is presented for 2s (default). Afterwards recall (immediate/delayed) and recognition tests are given. ___________________________________________________________________________________________________________________ DURATION ___________________________________________________________________________________________________________________ the default set-up of the script takes appr. 15 minutes to complete ___________________________________________________________________________________________________________________ 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: The specific Inquisit version used (the 'build') that was run computer.platform: the platform the script was run on (win/mac/ios/android) date, time: date and time script was run subject, group: with the current subject/groupnumber session: with the current session id blockcode, blocknum: the name and number of the current block (built-in Inquisit variable) trialcode, trialnum: the name and number of the currently recorded trial (built-in Inquisit variable) Note: trialnum is a built-in Inquisit variable; it counts all trials run; even those that do not store data to the data file such as feedback trials. Thus, trialnum may not reflect the number of main trials run per block. testPhase: 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 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) inquisit.version: Inquisit version run computer.platform: the platform the script was run on (win/mac/ios/android) startDate: date script was run startTime: time script was started subjectid: assigned subject id number groupid: assigned group id number sessionid: assigned session id number elapsedTime: time it took to run script (in ms); measured from onset to offset of script 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 (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 ___________________________________________________________________________________________________________________ STIMULI ___________________________________________________________________________________________________________________ see section Editable Stimuli (stimuli are reproduced based on the info published in: Wilhelm (2004) ___________________________________________________________________________________________________________________ INSTRUCTIONS ___________________________________________________________________________________________________________________ Instructions are not original to the task. They are provided by Millisecond Software 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) or Notepad (Windows). __________________________________________________________________________________________________________________ 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: 60000ms = 1 minute)
