Temporal Order and Spatial Memory Paradigms

Required Experiment Builder Version: 1.4.290 or higher
EyeLink Required: No
Type: Complete Example
Difficulty Level: Intermediate

These examples illustrate:
  • How to use Custom Class
  • How to use of Conditional nodes
  • How to use of ResultsFile and AddtoResultsFile action nodes to store results
Description:

This example is adapted after the experiment reported by Dreher, Banquet, Allilaire, Paillere-Martinot, Dubois, & Burond (1995).
  • Dreher, J. C., Banquet, J. P., Allilaire, J. F., Paillere-Martinot, M. L., Dubois, B., & Burnod, Y. (2001). Temporal order and spatial memory in schizophrenia: a parametric study. Schizophrenia Research. 51, 137-147.
This study reports a series of four tasks. Each trial begins with the same arrangement of 12 identical blue squares displayed on the screen in a pseudo-random pattern. The structure of each task was that of a standard delayed-response task: presentation of a stimulus, a delay (or no delay) and a response stage. The stimuli consisted of squares that changed color from blue to red. After presentation of the pattern, all squares disappeared. When they reappeared on the screen, a beep indicated that the participant had to respond by touching the squares according to specific instructions on each task.
  1. Spatial Recall Task: The stimulus presentation consisted of the simultaneous color changes of 2, 3, 4, or 5 squares depending on the set size. At response time, all squares reappeared as blue. The participant had to remember the location of the square that turned red during stimulus presentation.

  2. Temporal Recall Task: The stimulus presentation was formed by the successive color changes of 2, 3, 4, or 5 squares, depending on the set size. At the response time, the squares that belonged to the stimulus sequence reappeared as red while the others reappeared as blue. The participant had to reproduce the order in which the squares changed color during stimulus presentation, by touching the red squares in that order.

  3. Temporo-spatial Recall Task: Stimulus presentation was the same as in the temporal recall task, but at response time, all square reappeared as blue. Therefore, the participant had to remember both the location and the order of the squares that changed color, and respond by touching these squares in the same location and the same order as that shown during stimulus presentation.

  4. Temporo-spatial Recognition Task: Stimulus presentation was the same as in the temporo-spatial recall task, but after the delay another sequence was presented in order to be compared to the first. The sequences were either identical or different. After the presentation of the second sequence, the words "SAME" AND "DIFFERENT" appeared on the screen and the participant had to make a choice.
