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.
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.
Ecological validity is the extent to which research results can be applied to real-life situations outside of research settings. This issue is closely related to external validity but covers the question of to what degree experimental findings mirror what can be observed in the real world (ecology = the science of interaction between organism ...
Correlations that fit the expected pattern contribute evidence of construct validity. Construct validity is a judgment based on the accumulation of correlations from numerous studies using the instrument being evaluated. [22] Most researchers attempt to test the construct validity before the main research. To do this pilot studies may be ...
