Document Summary

We track changes in individual"s state-level expression of personality traits over time to investigate their distributional properties: central tendency (mean) and within-person variability (standard deviation). Individuals with little within-person variability have tight distributions of extraversion expression with little overlap (for high/moderate/low means). There are high levels of within-person variability in state-level expression of the. Big 5 personality traits, meaning individuals tend to express the full range of each trait in their daily lives. There is substantial stability of between-person differences in mean levels of behavioural expression or broad personality traits (consistent with claims of traditional trait theorists). There is substantial within=person variability in behavioural expression of traits at specific moments of observation (consistent with claims of situationists). Interactionism states within-person variability in trait expression across situations is. Not random but reflects systematic, stable relations between behavioural dispositions and situational cues. Measure each person"s situation-behaviour profiles and test whether these patterns are stable across independent observations of the person.
