Attitude

Question 227

The likelihood that an attitude will be automatically activated from memory on encountering the attitude object - Assumed to depend on the strength of the associative link in memory between the representation of the object and the evaluation of the object: the stronger the memory link between the object and its evaluation, the more quickly will the attitude come to mind
