Harold kelley says 3 info consistency, distinctiveness and consensus determine attribution. High situation consistency high, others low personal fundamental attribution error: underestimate situation, overestimate personal self-serving bias: personal success, situational failure. Primacy effect: attach to what first learned about person. Mental set told something, expect to see it, perceive it that way (schemas!!) Self-fulfilling prophecy: unconscious, person behaves in way toward someone that brings out behaviour expected by that person. Attitude: positive/negative reaction to person, action, object, concept (stimulus) Theory of planned behaviour: positive attitude towards something, increase. Stephen kraus overall attitudes predict behaviour to a degree want to engage in a behaviour. Fetsinger"s theory of cognitive dissonance uncomfortable tension between two things, told to person cognitively. I am truthful and i just told that student that the boring task is fun . Motivation to reduce dissonance counterattidunal is behaviour not equal to attitude!!
