Processing speed test
Simple visual judgements under tight time limits: spot the odd one out, find the exact match, count the targets.

What processing speed measures
Processing speed is how quickly and accurately you take in and judge simple information. Faster processing frees up mental capacity for harder thinking, which is why speed is one of the broad abilities included in modern intelligence tests such as the Wechsler scales.
The question types
- Odd one out: all figures are identical except one, which may be turned or mirrored.
- Exact match: find the figure identical to the target; the others differ by one detail.
- Visual search: count only the figures that exactly match the target.
How it's scored
Accuracy matters most: wrong answers count against you just like running out of time. Within the time limit, quick correct answers earn a small bonus, so speed matters, but never at the cost of accuracy.
Frequently asked questions
Does processing speed change with age?
Yes. It peaks in early adulthood and slowly declines, which is one reason IQ Atlas compares you with people your own age.
