Chapter 5 - The Biology of Learning Flashcards
(30 cards)
Taste aversion
- powerful disinclination toward eating or drinking certain substances
- easily learned, highly resistant to extinction, demonstrate biological constraints
Aversion therapy
- an undesirable behaviour is paired with stimuli associated with nausea or illness
- widely used to treat addictions
Latent inhibition
- unreinforced pre-exposure to a conditioning stimulus reduces the likelihood that it will be associated with a subsequent conditioned response
Blocking
- classical conditioning
- conditioning to a specific stimulus becomes difficult/impossible because of prior conditioning to another stimulus
Rescorla-Wagner model
- contiguity is neither sufficient nor necessary to explain classical conditioning
- what is learned in classical conditioning are relations among events
Higher-order conditioning
- conditioned stimulus takes on the role of an unconditioned stimulus
Tabula rasa
- model of the learner based on the assumption that people are born equal. each with no prior learning, inclinations, or thoughts
- ready to be shaped by experience
Evolutionary psychology
- theory that attends to biology and genetics as sources of explanation for human learning and behaviour
Autoshaping
- responses that are learned in experimental situations, even though they are not necessary to obtain reinforcement
- often appear to be part of the organism’s natural behaviours
Sign-tracking
- tendency of organisms to respond to signs related to survival, eating, and other genetically programmed tendencies
Instinctive drift
- tendency of organisms to revert to instinctual, unlearned behaviours
Biological constraints
- limitations on learning that result from biological factors rather than from experience
Folk knowledge
- widely held beliefs about the characteristics of people and the meanings of their behaviours and about the principles underlying natural phenomena
Sociobiology
- applies the findings of biology, anthropology, and ethology to the understanding of human social behaviour
- looks for biological explanations for behaviour
Ethology
- study of organisms in their natural habitats
- science of animal behaviour
Inclusive fitness
- refers to the fitness of genetically related groups relative to their likelihood of procreation
Altruism
- selflessness
- tendency to do things that increase the probability that other related individuals will survive
Pleasure center
- part of the brain thought to be involved in reinforcement
- specifically, part of the hypothalamus
Limbic system
- grouping of brain structures beneath the cerebral cortex
- mostly associated with emotion, memory, reinforcement, and punishment
Medial forebrain bundle
- group of nerve fibres associated with reinforcement
Periventricular tract
- group of nerve fibres associated with punishment
Agonist
- agent or drug that enhances the activity of some naturally occurring substance
Hypothalamus
- involved with the functioning of endocrine glands
Thalamus
- serves as major relay center for incoming sensory information
