Visual Working Memory
Chimp Test
Memorize numbered tile positions, then recover them from memory in ascending order after they disappear.
What does the Chimp Test measure?
It measures visual working memory — specifically, how many masked spatial positions you can hold and recall in ascending order after the numbered tiles disappear. The test was inspired by chimpanzee working-memory research and is a concrete measure of visuospatial short-term storage.
How should you interpret your Chimp Test score?
Most adults reliably track up to 7 tiles before accuracy drops; reaching 9 puts you in an exceptional range. The score reflects how well you encoded the initial layout before the mask appeared. Grouping tiles into a visual path or shape is one of the most effective strategies.
How does visual working memory connect to learning?
Many subjects are visual systems: equations, diagrams, anatomy, maps, chemistry structures, and code layout. When visual working memory is stronger, you can hold a layout while reasoning about relationships rather than constantly reloading the same picture, which speeds up pattern recognition and transfer.
Why does Vidbyte include the Chimp Test?
The masked-numeral paradigm is one of the cleanest isolated measures of visual working memory span available in a browser. Vidbyte uses it to signal how much visuospatial load a learner can sustain before the study material needs to be simplified or restructured.
Research basis
Research Basis
Kawai and Matsuzawa numeral span
The early masked-numeral paradigm asked chimpanzees to remember ordered positions after numbers disappeared.
Inoue and Matsuzawa Ayumu task
Ayumu recalled briefly shown numerals after masking; practice studies show humans can improve with training.
Working memory and cognition
Chimpanzee working-memory research shows how spatial recall, attention, and distraction resistance interact.
Extraordinary memory caution
Cook and Wilson re-examined claims about extraordinary chimpanzee working memory and emphasized practice and comparison limits.
Extended numeral ordering
Later touchscreen work tested chimpanzees on ordered Arabic numerals beyond the single-digit range.
