Chapter 6: Learning Flashcards
Change in an organism’s behavior or thought as a result of an experience
Learning
Process of responding less strongly over time to repeated stimuli
Habituation
Form of learning in which animals come to respond to a previously neutral stimulus that had been paired with another stimulus that elicits an automatic response
Classical conditioning (Pavlovian conditioning)
A stimulus that elicits an automatic response
Unconditioned stimulus
UCS
Automatic response to a non neutral stimulus that does not need to be learned
Unconditioned response
UCR
Response previously associated with a non neutral stimulus that is elicited by a neutral stimulus through conditioning
Conditioned response (CR)
Initially neutral stimulus that comes to elicit a response due to association with an unconditioned stimulus
Conditioned stimulus (CS)
Process by which organisms display a less pronounced conditioned response to conditioned stimuli that differ from the original conditioned stimulus
Stimulus discrimination
Developing a conditioned response to a conditioned stimulus by virtue of its association with another conditioned stimulus
Higher-order conditioning
Difficulty in establishing classical conditioning to a conditioned stimulus we’ve repeatedly experienced alone, that is, without the unconditioned stimulus
Latent inhibition
Learning controlled by the consequences of the organism’s behavior
Operant conditioning
Grasping the underlying nature of a problem
Insight
Principle asserting that if a stimulus followed by a behavior results in a reward, the stimulus is more likely to give rise to the behavior in the future
The Law of Effect (Thorndyke)
Small animal chamber constructed by Skinner to allow sustained periods of conditioning to be administered and behaviors to be recorded unsupervised
Skinner box
Outcome or consequence of a behavior that strengthens the probability of the behavior
Reinforcement
Presentation of a stimulus that strengthens the probability of the behavior
Positive reinforcement
Removal of a stimulus that strengthens the probability of the behavior
Negative reinforcement
Outcome or consequence of behavior that weakens the probability of the behavior
Punishment
Stimulus that signals the presence of reinforcement
Discriminative stimulus
Pattern of reinforcing behavior
Schedule of reinforcement
Reinforcing a behavior every time it occurs, resulting in faster learning but faster extinction than only occasional reinforcement
Continuous reinforcement
Only occasional reinforcement of a behavior, resulting in slower extinction than if the behavior had been reinforced continually
Partial reinforcement
Pattern in which we provide reinforcement following a regular number of responses
Fixed ratio schedule (FR)
Pattern in which we provide reinforcement after a specific number of responses on average, with the number varying randomly
Variable ratio schedule (VR)
Pattern in which we provide reinforcement for producing the response at least once following a specified time interval
Fixed interval schedule (FI)
Pattern in which we provide reinforcement for producing the response at least once during an average time interval, with the interval varying randomly
Variable interval schedule (VI)
Conditioning a target behavior by progressively reinforcing behaviors that come closer and closer to a target
Shaping
Neutral objects that becomes associated with a primary reinforcer
Secondary reinforcer
Item or outcome that naturally increases the target behavior
Primary reinforcer
Learning that’s not directly observable
Latent learning
Mental representation of how a physical space is organized
Cognitive map
Learning by watching others
Observational learning
Cell in the prefrontal cortex that becomes activated when an animal performs an action or observes it being performed
Mirror neuron
Evolutional predisposition to learn some pairings of feared stimuli over others owing to their survival value
Preparedness
Tendency for animals to return to innate behaviors following repeated reinforcement
Instinctive drift
An individuals preferred or optimal method of acquiring new information
Learning style
