An example of a person-situation interaction is: uncertainty orientation: would students do better on a test if they are uncertain about the test: for those high in uncertainty orientation the answer is yes- would approach new info. Depending on the situation the person faces, and on his or her characteristics, one would make different predictions about the expected behaviour: this is the basic principle of interactionism. Interactionism is found throughout the sciences: for example, plant growth can be affected by environmental effects, yet interactionism has been difficult to accept in traditional trait level analyses of personality. Two types of consistency have been found. Causes of behaviour: generalized (consistent, stable dispositions) Behavioural manifestations of personality: direct indicators of traits.
