PS270 Lecture Notes - Lecture 9: Self-Perception Theory, Electrodermal Activity, Electromyography
Document Summary
A favourable or unfavourable evaluative reaction toward something or someone. Exhibited in one"s beliefs, feelings, or intended behaviour. Presumed to determine judgements and behaviour across many situations. Likert rating scales (read each statement and circle level of agreement) Osgood semantic differential scales (ex rate opinion by circling one of the numbers) Observational: deliberate behaviour, nonverbal behaviour, physiological reactions. Facial electromyograph (muscle activity: implicit measures (implicit association test) Attitudes widely presumed to determine relevant behaviours however link in research is weak. Spontaneous, automatic behavour (priming concepts/social categories influence behaviour) An unpleasant internal state, results when people notice inconsistencies in their cognitions. Add consonant cognitions (focus on consonant belief, acquire new consonant info) Due to positive features of rejected option and negative features of chosen option. Affected by importance of decision, similarity of decisions, and certainty of decision (is it irrevocable?) Induce people to behave in a way inconsistent with their attitudes (counter attitudinal behaviour)
