Part 1: attribution theory- perceiving the causes of behaviour how ordinary people make sense of other people"s behaviour unterested in how we come to see stability in an unstable world: fritz heider. Person attributions: aka dispositional or internal attributions- they reflect stable properties of people. E. g. we might attribute friendly behaviour to friendly disposition. Environment attribution: aka situational or external attributions- reflect stable properties of environments. E. g. if you see someone engage in friendly behaviour you might conclude that it"s because the situation demanded to them to behave that way: we have a need to perceive stability. We cannot tolerate a world that changes from minute to minute. Gives us a sense of understanding, prediction, and control over our world: he was particularly interested in personal attributions, person attributions depend on perceived intentions. Jones nad davis in 1965 reserected heider"s ideas and made a new theory. Their paper was called from acts to dispositions.
