Chapter 5: Learning Flashcards
Learning
Any relatively permanent change in behavior brought about by experience or practice
Classical conditioning
- a learning process that occurs when two stimuli are repeatedly paired
- food and bell for dog
Unconditioned stimulus
Original stimulus, unlearned (food for dogs)
Unconditioned response
Automatic and involuntary response to unconditioned stimulus (salivation to food)
Conditioned stimulus
Neutral stimulus can become able to produce conditioned response after pairing it with unconditioned stimulus (bell with dog food)
Neutral stimulus
Has no effect on desired response prior to conditioning (bell not paired with anything)
Conditioned response
Learned response to conditioned stimulus (salivation to bell)
Basics for classical conditioning
- Conditioned stimulus (cs) before UCS (Metronome before food)
- CS and UCS close together in time (-5 sec)
- Must be paired several times before conditioning takes place
- CS: should be distinctive
Stimulus generalization
- Tendency to respond to stimulus similar to the original cs with the conditioned response (the more similar, the stronger)
(- sound similar to a bell)
Stimulus discrimination
- stop making generalized response to stimulus similar to original cs, because similar one is never paired with us
- (other similar sound won’t cause salivation anymore after realizing that there’s no food)
Extinction
- Disappearance of learned response following removal or absence of US
- (took food away from ticking, stopped salivating from ticking alone)
Spontaneous recovery
Reappearance of a learned response after extinction has occurred
Higher-order conditioning
Occurs when a strong conditioned stimulus is paired with a neutral stimulus, causing the neutral stimulus to become a second conditioned stimulus
Cognitive perspective
- Conditioning occurs because CS provides information/expectancy about the coming of the US
Conditioned emotional response (CER)
- Emotional response that has become classically conditioned to occur to learned stimuli
- (fear of dogs, emotional reaction to attractive person)
Vicarious conditioning
- Classical conditioning of an involuntary response/emotion by watching reaction of another person
Watson
Little Albert and white rat
Conditioned taste aversions
- Development of a nausea to particular taste because that taste was followed by a nausea reaction, occurring after only one association
- (Döner)
Biological preparedness
- animals learn certain associations, e.g. taste and nausea, with only one/few parings due to survival value of the learning
Operant conditioning
Learning of voluntary behavior through the effects of reinforcement and punishment
Law of effect
- If action is followed by pleasurable consequence: tend to be repeated,
- if followed by unpleasant consequence, tends not to be repeated
Operant
Any behavior that is voluntary and not elicited by specific stimuli
