Cognitive Load Basics

Cognitive load ideas (including instructional research associated with Sweller) say working memory is limited, so extra irrelevant detail or simultaneous goals can swamp learning and accuracy. That is a teaching and task-design idea, not a diagnosis and not an IQ brand.

What is cognitive load?

Roughly: how hard working memory is working. Intrinsic difficulty of the material, extraneous clutter, and useful generative effort are often distinguished in education research.

Why do switches feel heavy?

Task-switch-lite makes you hold a rule, drop it, and pick another. That control cost is a small load demonstration, not a clinical executive battery.

Dual n-back?

Holding two streams is a classic load. Dual-n-back-lite is a lite toy; it does not measure IQ and far transfer is mixed.

Is load the same as IQ?

No. People with more WM capacity may handle load better on average, but load is a property of the task-plus-person moment, not a substitute for a normed battery.

Learning design takeaway?

For real study, cut unnecessary split attention when you can. That advice is general; this site is not a school.

How should I practice here?

Try task-switch-lite, dual-n-back-lite, or flanker-lite to feel conflict and load. Hits stay game scores.

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.

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.

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.

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.

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.
