Psychology of LearningEXP4404 Chapter 12: The Limits of Learning Dr. Steve
Topics Covered • Physical Characteristics • Nonheritability of Learned Behavior • Heredity and Learning Ability • Neurological Damage and Learning • Critical Periods • Preparedness and Learning
Limits of Learning • Is behavior instinctual or learned through experience? • Some suggest that “lower” animals act mostly by instinct, but “higher” animals act mostly through learning • Some animals have more limitations as to what they can learn than do others due to biological/physical constraints
Limits of Learning • Interchangeable Parts Assumption (IPA) –
Limits of Learning • Physical Characteristics • Chimpanzees and Gorillas cannot learn to talk, but can learn to use sign language (see Washoe or Koko)
Nonheritability of Learned Behaviors • Lamarck • McDougall
Heredity and Learning Ability • Learned behaviors cannot be passed down to next generation, but ability to learn can • (see Idiocracy) • Tryon (1940) • Wolf vs Dog pups
Critical Periods • Critical Periods • Imprinting
Critical Periods • Imprinting distinct from learning in that: • Imprinting has . . . • Only certain kinds of stimuli • No practice required • Extinction & punishment are . . .
Preparedness and Learning • Seligman (1970) • Instinctive drift • Sets limits on learning • Revert back to innate tendencies
Preparedness and Learning • Behaviors may be easy or difficult to learn depending on . . . Contra- Prepared Highly Prepared Neutral Taste Aversions Bar Pressing Raccoon Trick Dog Not Wagging Tail SSDRs
Preparedness and Learning • Olton • Rats perform well, pigeons do not
Preparedness and Learning • Garcia Effect • Garcia tested • Principles of taste aversion Saccharine + lights + Noise (CS) X-radiation or Shock (US) Predisposition to associate taste (rather than external cues) with sickness
Preparedness and Learning • Why are some responses more easily associated with some stimuli than others?
