Chapter 6 Flashcards
(40 cards)
Innate ability to shift attention to novel or surprising events (bias towards novelty) and novel stimuli and events are potentially important (hear a noise in bed)
Orienting Responses
Durable change in behaviour that arises because of experience and allows us to adapt to environment
Learning
Reduced responsiveness to a repeated stimulus, learn to ignore things that are irrelevant, and role of habituation in consumerism versus transient (real life) experiences
Habituation
Increased responsiveness to a repeated stimulus, intense stimuli (frequently), and exaggerated response to unexpected stimuli (arousal)
Sensitization
Learning associations between stimuli and event (Pavlovian Conditioning)
Classical Conditioning
Ringing a bell triggers orientation and food trigger salivation
Before Conditioning
Bell presented before food and bell triggers food triggers salivation
During Conditioning
Triggers a response automatically
UCS (Unconditioned Stimulus)
Response happens automatically in response to UCS
UCR (Unconditioned Response)
Idea that stimulus that triggers response because if learning
CS (Conditioned Stimulus)
A responses that is learned
CR (Conditioned Response)
Environmental (contextual) cues can serve as a CS, tolerance is often context-specific, and CR can be opposite to that of UCR
Conditioned Tolarence
Weakening of the CR and the CS is presented without UCS, there is also Spontaneous Recovery is a recovery of an extinguish CR after a period of non-exposure to the CS
Extension: Extinction
Stimuli that are similar to CS will also elicit CR
Extension: Stimulus Generalization
Stimuli that are different from CS will not elicit CR
Extension: Stimulus Discrimination
Procedure in which an established CS1 is used to condition a second neutral stimulus (CS2)
Extension: Second-Order Conditioning
Four factors that influence classical conditioning
Strength of UCS, Contiguity, Informativeness of CS, and Blocking
Some CSs and UCSs are more easily associated than others (flavoured water can form CR is sick from injection)
Preparedness
One cue signals the occurrence of a second event (associations between cues and events and behaviour cones after stimulus)
Classical Conditioning
Learning if association between behaviour and consequences; behaviour comes before stimulus, and presentation of stimulus (food) depends on behaviour (pressing lever)
Operant Conditioning
Effects of behaviour determine how frequently it occurs in the future (if behaviour is reward, it continues, vice versa)
Thorndike’s Law of Effect
Stimulus is added after behaviour
Positive
Stimulus is removed after behaviour
Negative
Target behaviour maintained or increases
Reinforcement
