Ecological validity, the ability to generalize study findings to the real world, is a subcategory of external validity. [ 6 ] Another example highlighting the differences between these terms is from an experiment that studied pointing [ 7 ] —a trait originally attributed uniquely to humans—in captive chimpanzees.
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.
External validity is the validity of applying the conclusions of a scientific study outside the context of that study. [1] In other words, it is the extent to which the results of a study can generalize or transport to other situations, people, stimuli, and times.
The multitrait-multimethod (MTMM) matrix is an approach to examining construct validity developed by Campbell and Fiske (1959). [1] It organizes convergent and discriminant validity evidence for comparison of how a measure relates to other measures. The conceptual approach has influenced experimental design and measurement theory in psychology ...
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 ).
The task is to infer which of two alternatives has the higher criterion value. An example is which of two NBA teams will win the game, based on cues such as home match and who won the last match. The take-the-best heuristic entails three steps to make such an inference: [9] Search rule: Look through cues in the order of their validity.
In statistics, an ecological correlation (also spatial correlation) is a correlation between two variables that are group means, in contrast to a correlation between two variables that describe individuals. [1] For example, one might study the correlation between physical activity and weight among sixth-grade children.
The study had greater ecological validity than the original study, and the finding was that partners that were similar in terms of physical attractiveness expressed the most liking for each other – a finding that supports the matching hypothesis. [6]
