Psychology and Sociology: Chapter 3 Flashcards
Habituation
repeated exposure to the same stimulus can cause a decrease in response
Dishabituation
the recovery of a response to a stimulus after habituation has occurred; often noted when late in the habituation of a stimulus, a second stimulus is presented
Classic conditioning
Type of associative learning that takes advantage of biological, instinctual responses to create associations between two unrelated stimuli
Unconditioned stimulus
any stimulus that brings about a reflexive response
Unconditioned response
the innate or reflexive response
Neutral stimulus
stimuli that don’t produce a reflexive response
Conditioned stimulus
a normally neutral stimulus that, through association, now causes a reflexive response called a conditioned response
Acquisition
the process of using a reflexive, unconditioned stimulus to turn a neutral stimulus into a conditioned stimulus
Extinction
refers to the loss of a conditioned response, and can occur if the conditioned stimulus is repeatedly presented without the unconditioned stimulus
Spontaneous recovery
after some time, presenting subjects again with an extinct conditioned stimulus will sometimes produce a weak conditioned response
Generalization
a broadening effect by which a stimulus similar enough to the conditioned stimulus can also produce the conditioned response
Stimuli discrimination
an organism learns to distinguish between similar stimuli
Operant conditioning
Examines the ways in which consequences of voluntary behaviors change the frequency of those behaviors
Behaviorism
the theory that all behaviors are conditioned
Reinforcement
The process of increasing the likelihood that an animal will perform a behavior
Positive reinforcement
increase the frequency of a behavior by adding a positive consequence or incentive following the desired behavior
Negative reinforcement
increase the frequency of a behavior by removing something unpleasant
Escape learning (negative reinforcement)
describes a situation where the animal experiences the unpleasant stimulus and, in response, displays the desired behavior in order to trigger the removal of the stimulus
Avoidance learning (negative reinforcement)
occurs when the animal displays the desired behavior in anticipation of the unpleasant stimulus, thereby avoiding the unpleasant stimulus
Primary reinforcer
stimulus that an animal naturally responds to
Conditioned reinforcer or secondary reinforcer
stimulus that an animal is conditioned to respond to when it is paired with a primary reinforcer
Discriminative stimulus
indicates that a reward is potentially available in an operant conditioning paradigm
Positive punishment
adds an unpleasant consequence in response to a behavior to reduce that behavior
Negative punishment
removing a stimulus in order to cause reduction of a behavior
Fixed ratio (FR) schedules
reinforce behavior after a specific number of performances of that behavior
Continuous reinforcement
a fixed-ratio schedule in which the behavior is rewarded every time it is performed
Variable-ratio (VR) schedules
reinforce behavior after a varying number of performances of the behavior, but such that the average number of performances to receive a reward is relatively constant
Fixed-interval (FI) schedules
reinforce the first instance of a behavior after a specified time period has elapsed
Variable-interval (VI) schedules
reinforce a behavior the first time that behavior is performed after a varying interval of time
Shaping
the process of rewarding increasingly specific behaviors that become closer to a desired response
Latent learning
learning that occurs without a reward but that is spontaneously demonstrated once a reward is introduced
Preparedness
animals are able to learn behaviors that coincide with their natural behaviors
Instinctive drift
when animals revert to an instinctive behavior after learning a new behavior that is similar
Modeling
people learn what behaviors are acceptable by watching others perform them
Mirror Neurons
located in the frontal and parietal lobes of the cerebral cortex and fire both when an individual performs an action and when that individual observes someone else performing that action
