  2. Quick Question • Try to Guess what the color of your car says about your personality:

  3. Answer: • Nothing

  4. Objective Tests • “For Fun” tests • Tell you stuff you already know • “horoscopes” • Not linked with outcomes • Ex. Myers-Briggs • Clinical tests • Nuts/not nuts • Correlated with outcomes

  5. Reliability and Validity • Reliability: Does test always measure same thing. Consistency • Test-retest • Coefficient Alpha internal consistency • Validity: Does it measure what its supposed to • Predictive • Content • Construct • Face: A double edged sword • Ex. Rapists/college student ATW experiment

  6. The MMPI • Originally developed in 1940’s • Validity scales • Clinical scales • Supplemental scales • Empirical approach • Revised in 1989 • Forced answer format • Some complaints • Most researched personality test

  7. Projective Tests • Present neutral stimuli on which psychopathology can be projected • “there is no wrong answer…” • Normative responses • Originate in psychoanalytic theory • Clinical Interpretations • Reliability and validity issues • Standardization issues

  8. Rorschach Inkblot • Subject asked to state what they see in inkblot. • Multiple answers per card • Overall Quality • Normative responses • Explain why they saw it • Exner system: form, movement, color, white-space, theme, animal-human

  10. Intelligence • What is intelligence • Sir Francis Galton • Thomas Bouchard and twin studies • Binet • Mental age • IQ = MA/CA X 100
