Appearance and the required response
Recognizing a familiar shape among options differs from drawing it from memory. Specify which features matter and whether cues remain available. This makes errors interpretable instead of reducing every outcome to a vague impression of a good memory.
Visual and spatial memory
Remembering what an object looked like differs from remembering where it was. A matrix can involve both appearance and location, depending on the instructions. Success in one exercise does not establish photographic memory or guarantee recall of arbitrary images.
Reproduce a defined pattern
Use a memory matrix at a fixed size and mode. Alternatively, choose a few features in a picture, view it, hide it and describe those features. Check missing details and invented additions against the original before repeating.

Step-by-step worked example
What to prepare
Look at the three colored shapes. Prepare paper and pencils, or label colors in words. Positions are not scored in this exercise.
Task sample
What to do, step by step
View the shapes for ten seconds, attending to shape–color combinations.
Close Task sample and draw or describe all three combinations without cues.
Finish before revealing the model. Do not add details merely because they seem familiar.
Open the check and compare the combinations, recording shape errors, color errors and extra figures separately.
How to check your result
The sample contains a red triangle, blue circle and green square. A correct answer preserves all three combinations without additions. A blue triangle matches one shape but changes its color; record that mismatch specifically.
Your next attempt
Use a new three-shape sample with the same ten-second viewing period. Scoring positions as well would add another condition.
Examples in everyday tasks
Recognize an application icon
In a new application, you learn that a square with an outward arrow means export. Later, recognize it among print, download and send icons. The requirement concerns the symbol’s appearance. Remembering its exact position on the toolbar would add a different requirement about location.
Reproduce colors and shapes
A diagram legend uses a blue circle for a pump and a green diamond for a filter. Hide the legend and draw both symbols with their colors and shapes, then compare with the original. Note mixed-up colors, altered shapes and details you added that were never shown.
Draw a simple pattern from memory
Look at a pattern made of a stripe, two dots and a triangle. Remove the model and sketch it before reopening the original. Compare its features afterwards. Recognizing the same pattern among options provides additional cues, so keep that outcome separate from drawing without a model.
