Funny Memory
Also known as the Associative Memory Game, Funny Memory is derived from visual association memory tests. Participants view image pairs with unrelated objects combined in the same image (e.g., a fox in an ice cream cone), then must recall and recognize these associations through multiple phases: learning, delay, free recall, cued recall, and recognition.
ActivitySpec: lamp.funny_memory
Cognitive domain: Associative memory, visual memory
Configuration
The game uses a fixed set of image pairs. The delay period between learning and recall phases can be customized within the mindLAMP platform.
Usage
The assessment progresses through multiple phases:
- Learning — The participant is briefly shown 6 images with combined objects and asked to say aloud and record what two objects are in each image.
- Delay — Orientation questions (today's date, day of the week, season, etc.) fill a customizable delay period.
- Free recall — The participant records any image pairs they can remember.
- Cued recall — Each image is shown with only one object; the participant must name the missing object.
- Recognition — Four similar images are displayed, and the participant selects the one originally shown.

orientation_survey | object | Delay-period orientation responses (see below) |
The orientation_survey object contains responses to orientation questions asked during the delay period. Each field has a value (the participant's answer) and is_correct (boolean, compared against actual date/time):

start_time | Current time (H:M format; correct if within 5 minutes) |
day | Day of the week |
today_date | Day of the month |
month | Current month |
year | Current year |
season | Current season |
