Alternative brain tests
Elementary cognitive tasks
These aim to link the psychological and physiological aspects of intelligence and determine the speed at which the brain works. They test responses to stimuli and involve tasks that become progressively more complicated. Researchers claim that there is a correlation between results from these and IQ tests.
'Psychophysics' is the the physical study of psychological phenomena: how information from the senses is understood.

Visual illusions are particularly good for studying this area as illusions question our perception.
