Unformatted text preview: Chapter 6 Learning-How Nature Changes Us Basic Terminology • Learning – change in behavior or thought as a re sult of experience. 学学学学学学学学学学学学学学学学学学学 • Habituation – process by which we respond less strongly over time to repeated stimuli. 学学学学学学学学学学学学学 学学学学学学学学学学学学 • Sensitization – process by which we respond mo re strongly over time (especially for dangerous, ir ritating stimuli). 学学学学学学学学学学学学学学学学学学学学学学 Classical Conditioning • Ivan Pavlov – studied digestion in dogs; described Cla ssical Conditioning 学学学学学学 , involving: • UCS (unconditioned stimulus) – stimulus that pro duces automatic/unlearned/reflexive response. 学学 学学 • UCR (unconditioned response) –stimulus that pr oduces automatic/unlearned/reflexive response t o a UCS that occurs without learning. 学学学学 • CS (conditioned stimulus) – initially neutral stimul us, becomes associated with the UCS. 学学学学 • CR (conditioned response) – learned response. 学 学学学 Pavlov’s Classical Conditioning Model • P235 • By virtue of CS-UCS pairing, the CS come s to elicit the CR, a response closely relate d, but not identical, to the UCR. 学学学学学学学学学学学学学 学学学学学学学学学学学学学学学学 • Aversive Conditioning – classical condition ing to an unpleasant UCS. 学学学学学学学学学学学学学学学学学学 学学学 – Avoidance response 学学学学 • Acquisition – learning phase during which a CR is established. 学学学学学学学学学学学学学学学学学学学学学 • Extinction – gradual decrease and eliminat ion of the CR when the CS is presented re peatedly without the UCS. 学学学学学学学学学学学学学学学学学学学 学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学 Acquisition and Extinction • P236 • Spontaneous Recovery – sudden reemergence of an extinguishe d CR after a delay. 学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学学...
