Ecological validity can be considered a commentary on the relative strength of a study's implication(s) for policy, society, culture, etc. This term was originally coined by Egon Brunswik [1] and held a specific meaning. He regarded ecological validity as the utility of a perceptual cue to predict a property (basically how informative the cue is).
The ecological validity of a sensory cue in perception is the regression weight the cue X (something an organism might be able to measure from the proximal stimulus) in predicting a property of the world Y (some aspect of the distal stimulus). The "ecological validity" of X1 is its multiple regression weight when Y is regressed on X1, X2, and X3.
Ecological psychology is the scientific study of the relationship between perception and action, grounded in a direct realist approach. This school of thought is heavily influenced by the writings of Roger Barker and James J. Gibson and stands in contrast to the mainstream explanations of perception offered by cognitive psychology .
According to Tolman "Brunswik's untimely death on 7 July 1955, at the age of 52, came just as his doctrines of functionalistic achievement, representative design and ecological validity had begun to arouse widespread attention both in this country and abroad." [4] But the extent of his direct influence on psychology remains uncertain. [5]
Brunswik's lens model is a conceptual framework for describing and studying how people make judgments. For example, a person judging the size of a distant object, physicians assessing the severity of disease, investors judging the quality of stocks, weather forecasters predicting tomorrow's weather and personnel officers rating job candidates all face similar tasks.
The Gibsonian ecological theory of development is a theory of development that was created by American psychologist Eleanor J. Gibson during the 1960s and 1970s. Gibson emphasized the importance of environment and context in learning and, together with husband and fellow psychologist James J. Gibson, argued that perception was crucial as it allowed humans to adapt to their environments.

Cue validity is the conditional probability that an object falls in a particular category given a particular feature or cue. The term was popularized by Beach (1964) , Reed (1972) and especially by Eleanor Rosch in her investigations of the acquisition of so-called basic categories ( Rosch & Mervis 1975 ; Rosch 1978 ).
