The Science of Intelligence: Reaction Time and the G Factor
34:51 - 41:13 (06:22)
Reaction time is a measure of the speed of information processing and has been linked to the G factor, or general intelligence factor, through studies that manipulate the complexity of the instruction given to participants in reaction time tests.

Reaction time is a simple test to measure how quickly someone reacts to a stimulus, and it doesn't necessarily correlate with IQ.

Summary
Reaction time is a simple test to measure how quickly someone reacts to a stimulus, and it doesn't necessarily correlate with IQ. However, changing the instructions and adding a workload to the brain can help with memory recall and result in interesting research results.
