- No.
- A brief flash, then a mask, then a simple discrimination.
- Many speeded scores change with age in group data.
- Clicking a mouse is not the same as deciding which arrow.
- It can move alertness.
- Inspection-time lite and symbol-search lite.
Is faster always smarter?
No. Impulsivity is fast and wrong. Efficiency is a ratio idea, not a stopwatch trophy. Pratique — pas un QI clinique.
What is inspection time?
A brief flash, then a mask, then a simple discrimination. Our inspection-time lite is an original short set, not a published IT protocol. Pratique — pas un QI clinique.
Age and speed?
Many speeded scores change with age in group data. That is not a personal insult from a web millisecond. Pratique — pas un QI clinique.
Motor speed versus decision speed?
Clicking a mouse is not the same as deciding which arrow. Devices add lag. Do not compare phones as if they were a lab. Pratique — pas un QI clinique.
Caffeine?
It can move alertness. It is not a licensed IQ booster. Do not stack energy drinks to “beat” a lite. Pratique — pas un QI clinique.
What to try?
Inspection-time lite and symbol-search lite. Still not a PSI IQ index. Pratique — pas un QI clinique.
❓ Questions fréquentes
What is construct validity?
Construct validity is the argument that a score reflects a named idea — working memory, not “being clever in general.” It is built from theory, patterns of correlations, and failed rival explanations. A 20-trial number-Stroop lite can feel like control. Feeling is not a validity coefficient. This site never reports a licensed IQ. Pratique — pas un QI clinique.
What is construct validity? →What is criterion validity?
Criterion validity asks whether a score lines up with something you care about that is not the test itself — a later grade, a supervisor rating, or a Wechsler index. Concurrent means measured at the same time; predictive means later. A visual 2-back lite has no published criterion table. It is not an employment screen and not an IQ. Pratique — pas un QI clinique.
What is criterion validity? →What is content validity?
Content validity is whether the item set covers the skill or knowledge you claimed. A spelling test with only the letter Q is a coverage failure. Shape-span lite samples a tiny visuospatial sequence. It does not cover “all spatial intelligence.” Experts, blueprints and reviews build content arguments. A weekend hackathon does not. Pratique — pas un QI clinique.
What is content validity? →What is a confidence interval?
A 95% confidence interval is a procedure: if you repeated the study under the same model, 95% of such intervals would cover the parameter. It is not the probability that this one interval magically contains the truth after you saw it. Licensed IQ manuals turn a standard error into a range around a scaled score. Digit-span lite does not. Treat any integer from this site as a toy count. Pratique — pas un QI clinique.
What is a confidence interval? →What is item response theory?
Item response theory (IRT) models each item: harder items need more of the trait for a 50% chance of success; discriminating items separate nearby people. Computerized adaptive tests pick the next item from that model. Pattern-matrices lite is a fixed original set. It does not estimate a theta with published item parameters. It is not an IQ. Pratique — pas un QI clinique.
