Cognitive skills
Reaction speed vs IQ
Reaction speed can matter in timed tasks, but reasoning also depends on rule finding, memory, and accuracy.

Attention drift often shows up before you fully notice it. These signs help you pause and reset before accuracy drops.
Symbol substitution test
Can you decode this?
Symbol substitution tasks measure how efficiently you can use a simple rule under light time pressure.

Cognitive flexibility is the ability to update the active rule and avoid letting the old rule interfere.
Spatial visualization
Can you build the cube?
Cube-net tasks train spatial visualization by asking you to imagine how a flat layout folds into a 3D object.
Object-location memory
What moved?
Object-location memory combines item recall with spatial position, which makes it different from simple word recall.
Problem solving

A simple recall challenge can show how your memory strategy works: repetition, imagery, grouping, or pure attention.
Logical thinking
5 signs your logic is stronger than average
Good logic is not just getting answers right. It shows up in how you test assumptions, evidence, and alternative explanations.
