What cognitive tests usually measure
Cognitive tests are designed to measure specific mental processes. A good test is not just a collection of difficult questions; it should make clear what each task is intended to measure.
- Reasoning: finding rules, patterns and relationships.
- Working memory: holding and manipulating information briefly.
- Attention: staying focused and responding consistently.
- Processing speed: completing simple tasks accurately and quickly.
Why online testing needs caution
Online tests happen in uncontrolled environments. Device type, screen size, distractions and internet latency can affect performance. That is why results should be interpreted as orientative unless a test has been properly validated.
Why Open Cognitive Research avoids false precision
The first goal is to build a transparent baseline and collect clean data. Exact IQ-style claims should wait until enough data exists for calibration, reliability checks and appropriate comparison groups.
