Chapter 6: Learning Flashcards
1.4, 6.1 - 6.13
Three types of learning
nonassociative; associative; observational
Nonassociative
learning about a stimulus in the external world
1. habituation
behavioural response to a stimulus decreases
2. sensitization
behavioural response to a stimulus increases
Associative
learning the relationship between two pieces of information
1. Classical conditioning
when we learn that a stimulus predicts another stimulus
2. Operant conditioning
when we learn that a behaviour leads to a certain outcome
Observational
learning by watching how others behave
- Modeling
imitating a behaviour seen in others - Vicarious learning
learning to engage in a behaviour or not, after seeing others being rewarded or punished that action
Classical Conditioning
type of learning in which a neutral stimulus acquires the capacity to evoke a response that was originally evoked by another stimulus
- first described and demonstrated by Ivan Pavlov in 1903
Law of Effect
any behaviour that leads to a “satisfying state of affairs” is likely to occur again, and any behaviour that leads to an “annoying state of affairs” is less liekly to occur again
- likelihood of the occurance of a behaviour is influenced by its consequences
Operant Conditioning
voluntary responses come to be controlled by their consequences
- B.F. Skinner invented the operant chamber and theory
For punishment to be effective, we need to consider:
timing
intensity
consistency
Schedules of Reinforcement:
continuous
fixed ratio
variable ratio
fixed interval
variable interval
explain what each means
- continuous: every response is reinforce
- fixed ratio: fixed # of responses must be made before reinforcement
- variable ratio: random number of responses must be made before reinforcement
- fixed interval: first response after a specific period of time has elapsed is reinforced
- variable interval: first response after a random periods of time has elapsed is reinforce
what do each look like on a graph?
Extinction
in operant conditioning, extinction refers to gradual weakening and disappearance of a response tendency bc the response is no longer followed by reinforcement
Primary Reinforcers
things that are in themselves rewarding (innately satisfying, unlearned - biological)
Conditoned/Secondary Reinforcer
stimulus that gains its reinforcing power through assoc. with a primary reinforcer
- things we have learned to value - non-biologically beneficial
Shaping
the reinforcement of closer and closer approximation of a desired response
Dunning-Kruger Effect
- form of illusory superiority
- people lack the ability to evaluate their own performance in areas where they have little expertise
Illusory Superiority
form of false confience, when we believe that we are above average in just about everything
