Inspection time refers to the time required during visual processing to make accurate decisions about target stimuli that are presented.
Inspection time is considered to be strongly linked to processing speed. Studies of intellectual functioning have also shown a relationship between inspection time on visual processing paradigms and overall intellectual functioning. In general terms, the term inspection time can be used to describe the duration of visual processing conducted by a particular person on any task requiring a perceptual decision. When subjects are given as much time as needed to inspect a stimulus, they will vary in this duration, though in an uncontrolled experimental context it is difficult to know with certainty whether this reflects the processing speed limitations of the individual or other factors, such as their response bias. To control for this issue, cognitive and visual science researchers use the term more narrowly to refer to the...
