Psych 2 Flashcards
A test subject develops a response to a previously neutral stimulus by associating the stimulus with another stimulus that already elicited that response
(Pavlov’s Dog)
Classical Conditioning
The stage of learning over which a conditioned response to a new stimulus is established
Acquisition
The reappearance of the conditioned response after a period of lessened response
Spontaneous Recovery
Disappearance of the conditioned response
Extinction
The tendency to respond to stimuli that are similar to the conditioned stimulus
Stimulus Generalization
The learned lack of response to a stimulus similar to the conditioned stimulus
Stimulus Discrimination
A type of associative learning in which an individual becomes more or less likely to carry out a certain behaviour based on its consequences
(B.F. Skinner; Skinner Box)
Operant Conditioning
A consequence that increases the likelihood of a behaviour
Reinforcement
A stimulus that decreases the likelihood of a behaviour
Punishment
Introduction of a reinforcing stimulus in response to a desired behaviour
Positive Reinforcement
The removal of an unpleasant stimulus in response to a desired behaviour
Negative Reinforcement
Reinforcers and punishers that relate to a physiological need
Primary
Reinforces and punishers that require learning and social context to affect behavioural decisions
Secondary
When a learned behaviour allows a subject to escape the unpleasant stimulus
Escape Conditioning
When a learned behaviour allows the subject to avoid the unpleasant stimulus altogether by employing a specific response
Avoidance Conditioning
Describes how often and under what conditions a behaviour is reinforced
Reinforcement Schedule
Rewards are only given some of the times
Partial Reinforcement (intermittent Reinforcement)
Rewards are provided after a specified number of responses
I.e. A reward is given after every third time a mouse presses a lever
Fixed-Ratio
Partial Reinforcement
Rewards are provided after an unpredictable number of responses
I.e. A reward is given after a mouse presses a lever 3 tunes, then 5, then 2
Variable-Ratio
Partial Reinforcement
Rewards to a response are provided after a specified time interval has passed
I.e. A reward is given 20 seconds after the first time a mouse presses a lever
Fixed-Interval
Partial Reinforcement
Rewards to a response are provided after an unpredictable time interval has passed
I.e. A reward is given 3 minutes after the first time the mouse presses a lever, then 2 minutes after, etc..
Variable-Interval
Partial Reinforcement
Shaping behaviour towards a certain response by reinforcing successive approximations toward to desired behaviour
Shaping
Behaviours that are developmentally fixed
Innate Behaviour
Necessary for the associative learning if non-instinctual behaviours
Cognitive Processes
Witnessing another person’s actions, retaining information on that person’s behaviour, and later re-enacting what was learned through that observation in one’s own behaviour (Modeling)
Observational Learning
Neurons that fire both when a person is completing an action and when the person observes someone else completing the same action
Mirror Neurons
Feeling the emotions of others as though they are one’s own
Vicarious Emotions
The sum coordinated responses of organisms to the internal and external stimuli that they experience
Behaviour
All communication between people that does not involve words
Nonverbal communication
All interactions taking place between members of the same species
Social behaviour
