What is attention control?
It is goal-driven selection: amplifying what you meant to process and damping what you did not. Researchers often split selective, sustained, and executive attention. None of those slices is a full IQ battery or a medical label.
How is it different from raw IQ?
A standard IQ score summarizes several normed subtests. Attention tasks can correlate with those scores without being interchangeable. A flanker or change-detection lite run is a toy, not a deviation IQ.
What do laboratory tasks look like?
Flanker, Stroop, and anti-saccade tasks time how much distractors cost you. Change-detection displays probe visual working memory. Published batteries report norms; these web games do not.
Can I train it like a muscle?
Practice can speed a specific task. Far transfer to school grades or a clinical IQ is weakly supported. Treat letter-span-lite and change-detection-lite as familiarity, not treatment.
Why do my scores bounce?
Sleep, caffeine, device lag, and strategy shifts move milliseconds. Without a standard error of measurement, a 20-point web swing is not an IQ change.
How should I practice here?
Try flanker-lite, change-detection-lite, or go-no-go to feel selection under load. Do not screenshot a score as a clinical claim or an occupational credential.

IQ and Income
Surveys often find a positive correlation between cognitive-test scores and later earnings, but the path is noisy: education, health, networks, discrimination, and luck all sit in between. A correlation is not a paycheck forecast, and a higher score on a web game here is not a raise, a credential, or a clinical IQ. Group charts never tell you one person’s worth or hiring outcome.
IQ and Income →Visuospatial vs Verbal
Cognitive batteries often split visuospatial puzzles from verbal ones so you can see different strengths, not a single destiny. A high spatial sketch and a high vocabulary can diverge; neither pattern is a diagnosis. Online letter-span or hidden-figures lite games sample a slice of those families — they are not Wechsler indexes, not clinical IQ composites, and not career oracles.
Visuospatial vs Verbal →What Is Cognitive Flexibility?
Cognitive flexibility is the ability to update a rule when the world changes — switching from color to shape, or from one task set to another, without staying stuck. It is one executive-function toy, not a full intelligence profile. Task-switch lite on this site is original practice with no age norms, no standard error, and no clinical IQ attached to the hit count.
What Is Cognitive Flexibility? →Test Norming Basics
Norming is how a published test turns a raw hit count into a number you can compare with a reference group of the same age. Without a documented sample, a standard deviation, and a date, a web score is just a count. This site’s games are not normed batteries and must not be read as a clinical IQ, a school placement, or a medical finding.
Test Norming Basics →What Is a Z-Score?
A z-score says how many standard deviations a result sits from a group mean: (score − mean) / SD. IQ deviation scores are a dressed-up z on a 100/15 scale — but only when the test was actually normed. Typing a web-game total into that formula does not manufacture a clinical IQ, because you still lack the real mean, SD, and sample that the formula assumes.
