Ch 6 Powerpoint Flashcards
What are unlearned behaviors?
Instincts and reflexes
Instincts and reflexes are innate behaviors that organisms are born with, helping them adapt to their environment.
Define reflexes.
Motor/neural reactions to a specific stimulus
Reflexes involve specific body parts and primitive centers of the CNS, such as the spinal cord and medulla.
What are instincts?
Behaviors triggered by a broader range of events
Instincts are more complex than reflexes and involve the movement of the organism as a whole.
How is learning defined?
A relatively permanent change in behavior or knowledge that results from experience
Learning involves acquiring skills and knowledge through both conscious and unconscious processes.
What is associative learning?
When an organism makes connections between stimuli or events that occur together in the environment.
What is classical conditioning?
Process by which we learn to associate stimuli and, consequently, to anticipate events.
Who discovered classical conditioning?
Ivan Pavlov.
What is an unconditioned stimulus (UCS)?
Stimulus that elicits a reflexive response.
What is an unconditioned response (UCR)?
A natural unlearned reaction to a stimulus.
What is a neutral stimulus (NS)?
Stimulus that does not naturally elicit a response.
What is a conditioned stimulus (CS)?
Stimulus that elicits a response after being paired with an unconditioned stimulus.
What is a conditioned response (CR)?
The behavior caused by the conditioned stimulus.
Define higher-order conditioning.
An established conditioned stimulus is paired with a new neutral stimulus, leading to the new stimulus also eliciting the conditioned response.
What is acquisition in classical conditioning?
The initial period of learning when an organism learns to connect a neutral stimulus and an unconditioned stimulus.
What is extinction in classical conditioning?
Decrease in the conditioned response when the UCS is no longer presented with the CS.
What is spontaneous recovery?
The return of a previously extinguished conditioned response following a rest period.
What is stimulus discrimination?
When an organism learns to respond differently to various stimuli that are similar.
What is stimulus generalization?
When an organism demonstrates the conditioned response to stimuli that are similar to the conditioned stimulus.
What is habituation?
Learning not to respond to a stimulus that is presented repeatedly without change.
Who was John B. Watson?
A psychologist who used classical conditioning principles in the study of human emotion.
What was the Little Albert study?
A study where Little Albert was conditioned to fear furry stimuli.
What is operant conditioning?
A theory proposed by B.F. Skinner where organisms learn to associate a behavior and its consequences.
What does the law of effect state?
Pleasant consequences increase the likelihood of a behavior, while unpleasant consequences decrease it.
Define positive reinforcement.
Something is added to increase the likelihood of a behavior.
