Memory Game
A visual association memory task (TicTacToe-style) measuring visual, spatial, and temporal associative memory. Participants view a grid of gray boxes, then a short sequence of photos replaces some boxes before disappearing. The participant must recall both the order and location of the photos across learning trials, followed by a delayed recall.
ActivitySpec: lamp.memory_game
Cognitive domain: Visual, spatial, and temporal memory
Configuration
| Setting | Description |
|---|---|
| Foils | Number of incorrect images: 3 out of 9, or 4 out of 12 |
| Animation interval | Time in seconds between consecutive images in a sequence |
| Animation persistence | How long the full sequence remains visible after all images are shown |
Sample Instructions
"You will see a short sequence of pictures appear in the gray boxes. Please remember the pictures and their locations in order."
Usage
- Learning trials — A sequence of photos appears in the grid. The participant identifies the order and locations.
- Delay — A short timer period.
- Recall — The participant reproduces the sequence without seeing it first.
The task with 3 learning phases can be completed in about 90 seconds (excluding the delay).
