    • Recognition is one of the three basic memory tasks. It involves identifying objects or events that have been encountered before.
    • Recognition (re+cognition) is a process that occurs in thinking when some event, process, pattern, or object recurs. Coming from the base cognition; cognition has various uses in different fields of study and has generally accepted to be used for the process of awareness or thought. In psychology, cognition is used for information processing view of a person's psychological functions. This takes place as we process the stimuli with previous memories and experiences and find relationships between the current stimuli and our memories.

88 Tasks 1 and 2 can be treated as more or less equivalent and as different from Task 4. The distinctive characteristic of the highest-level perceptual tasks–recognition or identification–as compared to the lower level (discrimination) we there suggested to be the dimensionality of the decision space, i.e. the requirement for the observer to chose his or her response from a comparatively large number of alternatives.

1The term “discrimination task” is sometimes used in a different meaning, implying the judgement of a quantity being larger or smaller than another (the corresponding psychometric function then goes from −1 to 1). This is not implied here, the intended meaning being that the observer can discriminate between two broadly different stimuli and thereby identify each. The term “identification task” is sometimes used for that case but is avoided here to reserve the concept of identification for those tasks where discrimination between a few cases will not solve the identification.
