Residual effects of past on later behavior: Habituation and reasoned action perspectives

The frequency with which a behavior has been performed in the past is found to account for variance in later behavior independent of intentions. This is often taken as evidence for habituation of behavior and as complementing the reasoned mode of operation assumed by, such models as the theory of planned behavior In this article, I question the idea that the residual effect of past on later behavior can be attributed to habituation. The habituation perspective cannot account for residual effects in the prediction of low-opportunity behaviors performed in unstable contexts, no accepted independent measure of habit is available, and empirical tests of the habituation hypothesis have so far met with little success. A review of existing evidence suggests that the residual impact of post behavior is attenuated when measures of intention and behavior are compatible and vanishes when intentions are strong and well formed, expectations are realistic, and specific plans for intention implementation have been developed.
