- A proposed short-term store for visual appearance and spatial layout — remembering a path on a grid, a face-like avatar, or an embedded shape.
- The loop is more about inner speech and sound-based codes (digits, words).
- Corsi-type block tapping is a common lab spatial span.
- Abstract avatars on face-memory-lite are visual objects, not celebrity recognition and not a developmental face battery.
- Visual WM correlates with some reasoning tasks, but a grid game is not g.
- Try hidden-figures-lite, face-memory-lite, or corsi-blocks.
What is the sketchpad?
A proposed short-term store for visual appearance and spatial layout — remembering a path on a grid, a face-like avatar, or an embedded shape.
How is it not the phonological loop?
The loop is more about inner speech and sound-based codes (digits, words). You can load both at once; that dual load is cognitive load, not an IQ number.
Is Corsi the official sketchpad test?
Corsi-type block tapping is a common lab spatial span. This site’s corsi-blocks and hidden-figures-lite are practice cousins, not WAIS subtests.
Face memory?
Abstract avatars on face-memory-lite are visual objects, not celebrity recognition and not a developmental face battery.
Does a high visual span mean high IQ?
Visual WM correlates with some reasoning tasks, but a grid game is not g.
How should I practice here?
Try hidden-figures-lite, face-memory-lite, or corsi-blocks. They are toys for the sketchpad idea, not diagnoses.

Test–Retest Reliability
If you take a test twice, the number often moves. Psychometrics calls the stable part reliability and the bouncing part error, practice, mood, sleep, or a different form. A web game score is especially noisy.
Test–Retest Reliability →What Is a Standard Score?
Raw scores (items correct, milliseconds) are not comparable across ages or tests. A standard score rescales them so that, in a reference sample, the mean and spread are fixed. This site does not convert game hits into that scale.
What Is a Standard Score? →IQ and Job Performance
Industrial-organizational research often finds that general mental ability predicts job performance better in more complex roles, with validity coefficients that are real but far from 1.0. This article is descriptive. It is not a recommendation to choose or reject a career from a web score.
IQ and Job Performance →Nutrition and Cognition
Brains run on ordinary metabolism. Skipping meals, dehydration, and extreme restriction can make attention feel worse in the short run. That is not the same as a supplement raising IQ, and this site does not sell or endorse pills.
Nutrition and Cognition →Heat and Test Scores
Hot, poorly ventilated rooms make many people slower and more irritable. Research on ambient temperature and exam or cognitive-task performance is mixed but often points to discomfort and attention costs — not a rewritten intelligence.
