Am I Me or Am I the Situation?. Does Personality Change?. Foundation of personality psychology is personality stability and predictive utility If personality changes this threatens the field’s usefulness Especially if change is random Prediction difficult

Does Personality Change? • Foundation of personality psychology is personality stability and predictive utility • If personality changes this threatens the field’s usefulness • Especially if change is random • Prediction difficult • Central debate has been whether personality or situation better predictor
Person or Situation? • Account for 2 observations: • Behavior varies across situation • Perceive ourselves as the same person • Are we different people in different situations? • Historical emphasis on one or the other • Internal or external • Implications for methodology, Qs, etc.
Person-Situation Debate • Either Or Question • 1940s, 1950s internal emphasis • Freudian personality types (anal character) • Projective techniques and trait inventories
Mischel (1968) challenge • Dissatisfied with internal emphasis on traits • Argued for situational focus • Situational changes predict behavior > traits • Ostensive personality consistency due to situational consistencies • Learning view
Mischel (1968) challenge • Primary criticisms • Little evidence of cross-situation consistency in behavior • Traits dependent on situational evocation • Traits poor predictors of behavior across situations (r < = .30) • Trait merely labels w/ no independent reality
Controversy • Leads to near collapse of personality psychology • If traits aren’t real/stable/predictive what use are they? • No need for personality if behavior primarily due to situational features • Predict/understand behavioral variation via situation
Field’s Response • Funder & Ozer (1983) • Reanalyzed studies showing situational influence on behavior • Situation had ~same predictive power as personality (r < = .30) • Power of situation = power of personality • Both rs < = .30
Activity 13: Mischel • In groups of 3-4 • Describe the response to Mischel’s challenge made by Epstein. How does Mischel (re) challenge Epstein here? • Next describe at least 1 more response made by the field in defense of traits. • PLEASE TURN THESE IN AFTER CLASS!
Kenrick & Funder: Fallout • PS debate led to numerous hypotheses regarding the relative importance of personality/situation • Many assumed that personality was an artifact, unreal and a weak predictor (empirically and conceptually) of behavior
Kenrick & Funder: Hypotheses • H1: Personality is in eye of beholder • Interrater agreement fails to support • H4: Shared (incorrect) stereotypes account for rater agreement • Ratings predict independent behavioral manifestations (aggression, delay of gratification, social behavior)
Kenrick & Funder: Hypotheses • H7: Effect of personality on behavior too small to be meaningful (.30) • Situational features share effect size (.30) • Small can be important & meaningful • Effect increases with aggregation
Mischel’s Fallout • 1980s/90s reality/stability of traits revealed • Genetics, longitudinal, cross-cultural studies • Interactionism (nature & nurture): • Effect of personality depends on situation • Effects of situation depends on personality • Behavior = traits + situation + traits x situation • Greater external validity (Cattell: multivariate world)
Lessons from PS Debate • Kenrick & Funder • Gray > black or white (closer to reality) • Limitations on behavioral prediction from personality and situation • Boundary conditions on personality ratings • Personality & Social Psych MUST work together
Knowns • Person & situation important • Consistency varies across people • Situations vary in their power • Consistency varies as a function of both
Unknowns • What person & situation Vs best? • Goals • Situational taxonomy
Future: Integration? • Social-cognitive approach of Mischel • Trait approach of Costa & McCrae • Function & structure?
