Does IQ stay the same from childhood?
Correlations between childhood and adult IQ increase as the first test is given later. Early scores have more error and more room to move. Still not destiny.
What about gifted programs?
Placement decisions belong to schools and licensed psychologists using appropriate tools. A face-memory-lite run is not one of those tools.
Measurement error in kids?
Younger children are more variable in attention and cooperation. Standard errors are not printed on this website’s games.
Can parents raise IQ with these games?
You can play. You should not expect a new official IQ. Far transfer from casual web practice is weakly supported.
Is this a developmental diagnosis?
No. Concerns about delay or giftedness need professional evaluation, not a category-fluency toy.
How should I practice here?
Adults curious about memory can try word-recall-lite. Do not use it as a child IQ screen.

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.
