Chapter 5 Flashcards
Phenotypic plasticity
The ability of an organism to produce different phenotypes depending on environmental conditions
Habituation and Sensitization
Two simple single stimulus forms of learning
Pavlovian conditioning experiments
Two stimuli:
The conditioned stimulus
Unconditioned stimulus
Conditioned stimulus
Stimulus that initially fails to elicit a response, only when a second stimulus is present
ex.blue stick
Unconditioned stimulus
A stimulus that elicits vigorous response in the absence of training
ex. Cat odor
Conditioned response
Response to stimulus
ex. Rat hiding
Appetitive stimulus
Positive, pleasant, or rewarding stimulus
Aversive stimulus
Unpleasant stimulus
Excitatory conditioning
Positive relationship between stimulus and condition
Inhibitory conditioning
Negative relationship
Ex. Light means no food
Overshadowing
When a stimulus retards the learning of a species
Second order conditioning
A new 3rd stimulus is introduced before the firsts to elicit the conditioned response
Operant conditioning
Learning that occurs when a response made by an animal is somehow award
Law of effect
Principle of psychology
Responses to stimuli that produce a satisfying or pleasant state of affairs in a particular situation or more likely to occur again for the response will strengthen the situation
Mechanisms of learning
Stimulus
Stimulus-Stimulus
Response reinforcer
