Learning & Memory Flashcards
What is non-associative learning? What are the 2 types?
Learning about a stimulus (sight or sound) in an external world. Habituation and Sensitization.
What is habituation? What is dis-habituation?
A decrease in behavioral response due to familiarity of a stimulus. Increased response due to change in the familiar stimulus.
What is sensitization?
An increase in behavioral response due to exposure to a stimulus.
What is associative learning? What are the 2 types?
Learning through the association/relationship of 2 pieces of information. Classical conditioning and operant conditioning.
What is classical conditioning?
A neutral stimulus that elicits a response due to its association with a stimulus that produces a response.
What is second-order conditioning?
Pairing a new stimulus with a conditioned stimulus to create a new conditioned response.
What is extinction?
When a conditioned response is forgotten due to presenting the conditioned stimulus alone (w/o reward).
What is spontaneous recovery?
A weak response to a stimulus after extinction and a resting interval.
What is stimulus generalization?
When responses may be elicited by stimuli that is similar to the conditioned stimulus.
What is discrimination?
The ability to differentiate between a conditional stimulus and other stimuli.
What is fear conditioning?
When neutral stimuli becomes threatening stimuli.
What is operant conditioning?
The consequence of an action (response) determines whether the action will be performed again.
What is the Law of Effect and shaping?
The theory that behavior is govern by its consequence. Small rewards are used to target a bigger behavior.
What are the 4 types of reinforcement?
Primary reinforcement (unconditional stimulus) and secondary reinforcement (conditioned/learned stimulus).
Positive (increases a response by adding to the stimulus) and negative (increases a response by removing).
What are the 2 types of punishments?
Aversive/positive (decreasing a response by adding to the stimulus) and response cost/negative (decreasing a response by removing).
What is equipotentiality?
The idea that any conditioned stimulus paired with an unconditioned stimulus results in learning.
What is the partial reinforcement extinct effect? What are the 4 types of partial reinforcement? Which provide the highest response rates?
The idea that partial reinforcement experiences extinction less than continuous reinforcement. Fixed ratio (after a # of responses), variable ratio (after an average # of responses), fixed interval (after the 1st response and # of time), variable interval (after 1st response and average # of time). Variable ratio and variable interval.
How do biological factors relate to classical conditioning? (Contiguity and contingency)
Biological constraints allow for biological preparedness. The conditioned stimulus acts a predictor and the conditioned response prepares for the unconditioned stimulus.
Contiguity: learning only occurs when the conditioned stimulus is presented BEFORE the unconditioned stimulus.
Contingency: the conditioned stimulus should suggest the unconditioned stimulus will be offered.
How do biological factors relate to operant conditioning? (Contiguity and contingency)
Biological constraints allow for built-in predispositions. Tolman (1948): Learning involves both behavioral change and the acquisition of new knowledge (e.g. cognitive maps).
Contiguity: learning occurs when the reinforcement or punishment occurs immediately after a response.
Contingency: the reinforcement or punishment should occur more likely after the response. Otherwise, learned helplessness can occur.
What is observational (social) learning? What are the 2 types?
Learning through observing others (in relation to behaviorism). Modeling and vicarious learning.
What is modeling?
Learning through demonstration and then imitation. Modeling someone can be influenced by their attractiveness, status and similarity to oneself (and whether that similarity is achievable of oneself).
What are the words for fear associations and reward associations?
Phobias and addiction.
What neurotransmitter provides pleasure? Where in the brain?
Dopamine. In the nucleus accumbens.
What is encoding? When does it occur in the MSM model?
The process of a stimulus or event transforming into memory. The transference of STM to LTM.
