Unit 4 Flashcards
Albert Bandura
Conducted the Bobo doll experiment, which demonstrated that aggression is learned by observing and modeling others
Ivan Pavlov
Conditioned dogs to salivate at the sound of a bell after repeated pairings with food, thereby discovering classical conditioning
B.F Skinner
the behaviorist most responsible for developing operant conditioning theory
Edward Thorndike
behaviorist known for the law of effect, which served as the foundation for Skinner’s operant conditioning theory
Learning
Any relatively permanent change in behavior brought about by experience or practice
Behaviorists
Believed psychology should be the scientific study of observable behavior & all learning occurs through interactions with the environment
Classical conditioning
the process of repeatedly pairing an original (unconditioned) stimulus which naturally produces a reflexive (unconditioned) response, with a new (neutral) stimulus such that the new stimulus produces the same response
Neutral stimulus
Produces no effect until paired with an unconditioned stimulus
Unconditioned stimulus
A stimulus (UCS) is one that unconditionally, naturally, and automatically triggers an unconditioned response or reflex
Unconditioned response
An unlearned response that occurs naturally in reaction to the unconditioned stimulus
Conditioned stimulus
: The conditioned stimulus is a previously neutral stimulus that, after becoming associated with the unconditioned stimulus, eventually comes to trigger a conditioned response
Conditioned response
The conditioned response is the learned response to the previously neutral stimulus
Acquisition
initial stage of learning when a response is first established and gradually strengthened
Higher-Order Conditioning
A procedure in which the conditioned stimulus in one conditioning experience is paired with a new neutral stimulus, creating a second (often weaker) conditioned stimulus
Extincion
The occurrences of a conditioned response decreases or disappears, this happens when a conditioned stimulus is no longer paired with an unconditioned stimulus
Spontaneous recovery
Refers to the return of a previously extinguished conditioned response following a rest period
Stimulus generalization
The tendency for the conditioned stimulus to evoke similar responses after the response has been conditioned
Stimulus discrimination
The ability to differentiate between a conditioned stimulus and other stimuli that have not been paired with an unconditioned stimulus
Taste aversion
The avoidance of a certain food following a period of illness after consuming that food
Edward thorndike’s law of effect
According to this principle, actions that are followed by desirable outcomes are more likely to be repeated while those followed by undesirable outcomes are less likely to be repeated
Operant conditioning
Method of learning that occurs through rewards and punishments for behavior
Shaping
Procedure in which reinforcers gradually guide an animal’s actions toward a desired complex behavior
Reinforcement
any event that strengthens or increases the behavior it follows
positive reinforcement
Favorable events or outcomes that are presented after the behavior, response or behavior is strengthened by the addition of something
