Chimp Test – Visual Memory and Sequence Recall Test
The Chimp Test is a fascinating cognitive assessment designed to push the limits of your visual working memory. By challenging you to recall the position of numbers in sequence, it provides a clear measure of your short-term retention capacity and attention to detail.
Quick Answer
- • What it measures: Visual working memory and sequential recall ability
- • Who it's for: Anyone wanting to test their short-term visual memory capacity
- • Good score: 9+ numbers (see full benchmarks)
- • Key factors: Focus, pattern recognition strategies, and fatigue levels

Take the Chimp TestWhat Is the Chimp Test?
The Chimp Test is a visual-spatial memory task. It presents a series of numbers scattered randomly across a grid. Your goal is to click the numbers in ascending order (1, 2, 3, etc.).
The catch? As soon as you click the number "1", all other numbers are covered by white squares. You must then rely entirely on your short-term visual memory to click the remaining hidden numbers in the correct sequence.
This test gained popularity from primate research where chimpanzees demonstrated an extraordinary ability to complete this task at high speeds—often faster and more accurately than untrained humans. However, with practice, humans can also achieve impressive scores.
What Does the Chimp Test Measure?
Visual Working Memory
The primary metric is your capacity to hold visual information (the location of numbers) in your mind for a few seconds while performing a task (clicking them in order).
Spatial Span
It assesses spatial span—the number of items and their specific locations you can recall simultaneously. This is distinct from verbal memory (remembering words).
Attention & Focus
Success requires intense, momentary concentration. Any lapse in focus usually results in losing the mental "image" of the number locations.
Processing Speed
While accuracy is key, the test also implicitly measures how quickly you can encode visual information before the memory fades.
How the Chimp Test Works
The test operates in levels, starting simple and increasing in difficulty:
- Observation Phase: Numbers appear on the screen (e.g., 1 to 4). You can take as long as you need to memorize their positions.
- Recall Phase: Once you click the first number ("1"), all other numbers are hidden behind blocks.
- Execution: You must click the blocks where 2, 3, 4, etc., were located, in the correct order.
- Progression: If successful, the next level adds one more number (e.g., 1 to 5). If you make a mistake, you receive a "strike." Usually, 3 strikes ends the test.
What Is a Good Chimp Test Score?
Scores on the Chimp Test are determined by the maximum number of items you can successfully recall in sequence. Here is a general benchmark for adult performance:
| Level | Score Range (Numbers Recalled) |
|---|---|
| Below Average | 4 – 6 |
| Average | 7 – 9 |
| Above Average | 10 – 13 |
| Excellent | 14+ |
What Affects Chimp Test Performance?
Several factors can influence how well you perform on this visual memory task:
Age
Visual working memory tends to peak in young adulthood (20s) and gradually declines with age. Children often perform surprisingly well on this test.
Fatigue
Tiredness severely impacts working memory. A well-rested brain can hold significantly more visual items than a fatigued one.
Distractions
Because the memory trace is fragile, even a split-second distraction can cause the mental image of the number positions to vanish.
Strategy
Untrained users rely on pure recall. Advanced users employ "chunking" or "pathing" strategies to remember larger sets.
How to Improve Your Chimp Test Score
Like many cognitive skills, visual memory is trainable. Here are practical ways to boost your score:
- Use "Chunking": Instead of trying to remember 10 individual locations, group them into shapes (e.g., "a triangle of three numbers here, a line of two there").
- Create a Path: Visualize a line connecting 1 to 2 to 3, creating a mental drawing on the screen.
- Soft Focus: Rather than looking directly at each number individually, try to soften your gaze to take in the whole screen at once. This utilizes your peripheral vision and holistic processing.
- Consistent Practice: Playing the Chimp Test regularly for 5-10 minutes can lead to noticeable improvements as your brain adapts to the specific demands of the task.

Memory Grid Test
A pure visual memory test where you must recall the pattern of highlighted squares. Less focus on sequence, more on spatial pattern retention.
Reaction Time Test
Measure your raw processing speed. While the Chimp Test measures memory, this test measures how quickly your brain can respond to a stimulus.
How Averages Are Estimated
This test is based on the 'Ayumu' chimpanzee experiments conducted at the Primate Research Institute of Kyoto University. The test measures spatial working memory capacity and speed.
Measurement Limitations
Human performance on this test varies significantly with practice. While the original study suggested chimpanzees have superior working memory, subsequent research has shown that humans can achieve similar performance levels with extensive training.
