Term
observational learning
Definition
learning by observing others and imitating their behavior
Term
latent learning
Definition
learning that occurs but is not demonstrated until there is incentive to do so
Term
instinctual drift
Definition
the tendency for an animal to drift back from a learned operant response to an innate, instinctual response to an object
Term
overjustification effect
Definition
a decrease in an intrinsically motivated behavior after the behavior is extrinsically reinforced and then the reinforcement discontinued
Term
intrinsic motivation
Definition
the desire to perform a behavior for its own sake
Term
extrinsic motivation
Definition
the desire to perform a behavior for external reinforcement
Term
Yerkes-Dodson law
Definition
a law describing the relationship between the amount of arousal and the performance quality on a task- increasing arousal up to some optimal level increases performance quality on a task, but increasing arousal past this point is detrimental to performance
Term
arousal theory
Definition
the theory of motivation which proposes that our behavior is motivated to maintain an optimal level of physiological arousal
Term
incentive theory
Definition
a theory of motivation which proposes that our behavior is motivated by incentives, external stimuli that we have learned to associate with reinforcement
Term
drive-reduction theory
Definition
a theory of motivation which proposes that our behavior is motivated yo reduce drives created by unsatisfied bodily needs to return the body to a balanced internal state
Term
motivation
Definition
the set if integral and external factors that energize our behavior and direct it toward goals
Term
variable-interval schedule
Definition
a partial schedule of reinforcement in which the time that must elapse on each trial before a response will lead to the delivery of a reinforcer varies from triall to trial
Term
fixed-interval schedule
Definition
a partial schedule of reinforcement in which a reinforcer is delivered after the first response is given once a set interval of time has elapsed
Term
variable-ratio schedule
Definition
a partial schedule of reinforcement in which the number of responses it takes to obtain a reinforcer varies on each trial but averages
Term
fixed-ratio schedule
Definition
a partial schedule of reinforcement in which a reinforcer is delivered each time a fixed number of responses are made. the fixed number can be any number greater than one
Term
partial-reinforcement effect
Definition
the finding that operant responses that are reinforced on partial schedules are more resistant to extinction that those reinforced on a continuous schedule
Term
partial schedule of reinforcement
Definition
reinforcing the desired operant response only part of the time
Term
continuous schedule of reinforcement
Definition
reinforcing the desired operant response each time it is made
Term
stimulus generalization
Definition
giving the operant response in the presence of stimuli similar to the discriminative stimulus. the more similar the higher that response rate
Term
stimulus discrimination
Definition
learning to give the operant response only in the presence of the discriminative stimulus
Term
discriminative stimulus
Definition
the stimulus that has to be present for the operant response to be reinforced
Term
spontaneous recovery
Definition
the temporary recovery of the operant response following a break during extinction training
Term
extinction
Definition
the diminishing of the operant response when it is not longer reinforced
Term
acquisition
Definition
the strengthening of a reinforced operant response
Term
cumulative record
Definition
a record of the total number of operant responses over time that visually depicts the rate of responding
Term
shaping
Definition
training a human or animal to make an operant response by reinforcing successive approximations of the desired response
Term
behavior modification
Definition
the application of classical and operant conditioning principles to eliminate undesirable behavior and teach more desirable behavior
Term
secondary reinforcer
Definition
a stimulus that gains its reinforcing property through learning
Term
primary reinforcer
Definition
a stimulus that is innately reinforcing
Term
negative punishment
Definition
punishment in which an appetitive stimulus is removed
Term
negative reinforcement
Definition
reinforcement in which an aversive stimulus is removed
Term
positive punishment
Definition
punishment in which an aversive stimulus is presented
Term
positive reinforcement
Definition
reinforcement in which an appetitive stimulus is presented
Term
aversive stimulus
Definition
unpleasant
Term
appetitive stimulus
Definition
pleasant
Term
punishment
Definition
the process by which the probability of a response is decreased by the presentation of a punisher
Term
reinforcement
Definition
the process by which the probability of a response is increased by the presentation of a reinforcer
Term
punisher
Definition
a stimulus that decreases the probability of a prior response
Term
reinforcer
Definition
a stimulus that increases the probability of a prior response
Term
law of effect
Definition
a principle developed by Edward Thorndike that says that any behavior that results in satisfying consequences tends to be repeated and that any behavior that results in unsatisfying consequences tends not to be repeated
Term
operant conditioning
Definition
learning to associate behaviors with their consequences. behaviors that are reinforced will be strengthened, and behavior that are punished will be weakened.
Term
stimulus discrimination
Definition
the elicitation of the conditioned response only by the the conditioned stimulus or only by a small set of highly similar stimuli that includes the conditioned stiumus
Term
stimulus generalization
Definition
the elicitation of the conditioned response to stimuli that are similar to the conditioned stimulus. THe more similar the stimulus the stronger the response
Term
spontaneous recovery
Definition
a partial recovery of strength of the conditioned response following a break during extinction training
Term
extinction
Definition
the diminishing of the conditioned response when the unconditioned stimulus no longer follows the conditioned stimulus
Term
acquisition
Definition
acquiring a new response to the conditioned stimulus
Term
trace conditioning
Definition
a classical conditioning procedure in which the conditioned stimulus precedes the unconditioned stimulus but is removed before the unconditioned stimulus is presented so the two stimuli do not occur together
Term
delayed conditioning
Definition
a classical conditioning procedure in which the conditioned stimulus precedes the unconditioned stimulus and remains present until after the unconditioned stimulus is presented so that the two stimuli occur together
Term
conditioned response
Definition
the response that is elicited by the conditioned stimulus in classical conditioning
Term
conditioned stimulus
Definition
the stimulus that comes to elicit a new response
Term
unconditioned response
Definition
the response in a reflex that is automatically elicited by the unconditioned stimulus
Term
unconditioned stimulus
Definition
the stimulus in a reflex that automatically elicits and unconditioned response
Term
reflex
Definition
a stimulus-response pair in which the stimulus automatically elicits the response
Term
classical conditioning
Definition
acquiring a new response to a previously neutral stimulus that reliably signals the arrival of an unconditioned stimulus
