PHRENOLOGY

THE BIOLOGICAL/EVOLUTIONARY APPROACHES (SHORT)
THE PHENOMENOLOGICAL/HUMANISTIC APPROACH (SHORT)

WHY SO MANY THEORIES?
PHILOSOPHICAL ASSUMPTIONS
EVALUATING PHILOSOPHICAL ASSUMPTIONS
COHERENCE
- is the position clear/logical/consistent?
RELEVANCE
- does theory deal w/issues important/meaningful today? are they compatible w/empirical reality?
COMPREHENSIVENESS
- does it encompass wide phenomena array? does it cover what it claims profoundly/superficially?
COMPELLINGNESS
- does it convince YOU?
WHAT MAKES A USEFUL THEORY
PERSONALITY & CULTURE
INDIVIDUALISTIC CULTURES
COLLECTIVIST CULTURES
THE PERSON-SITUATION DEBATE
WALTER MISHCELL (1968): PERSONALITY & ASSESSMENT
- strongly contested since late 1960s
- Q: is the person/situation ^ important in determining what people do?
- situational variables best suited to predicting behaviour in specific situations
- personality traits predict beh patterns that persist across situations/time
THE FORER/BARNUM EFFECT: DESCRIPTION
FORER (1948)
- people tend to accept vague/general personality descriptions as uniquely applicable to them
- they accept questionable/sometimes false statements about them if they’re deemed positive/flattering enough
THE FORER/BARNUM EFFECT: IN ACTION
FORER (1948)
- asked students to evaluate personality description 0-5 (5 = excellent; 4 = good)
- personality description accuracy amazed pps
- class average evaluation = 4.26
- test repeated hundred times w/psych students; average still 4.2
- pseudoscience = tart/astrology/fortune telling
- personality theories/assessments MUST be specific/reliable
THE PSYCHOMETRIC APPROACH
