Term
classical conditioning
Definition
a result of learning connections between differency events. eg gambling
Term
unconditioned stimulus
Definition
a stimulus that can reflexively elicit a response
Term
unconditioned response
Definition
a response relfexively elicited by an unconditioned stimulus
Term
conditioned stimulus
Definition
a stimulus that, after conditioning, is able to elicit a nonreflexive response
Term
conditioned response
Definition
a response that, after conditioning, is elicited by a conditioned stimulus.
Term
acquisition
Definition
the period during which an organism is learning the association of the stimuli
Term
extinction
Definition
the process by which classical conditioning is unlearned
Term
spontaneous recovery
Definition
after extinction, when the UCS elicits a weak CR
Term
generalization
Definition
the tendency for stimuli similar to the CS to elicit the CR
Term
second-order conditioning
Definition
a neutral stimulus is paired with a CS rather than an UCS. Stage 1 is a regular clasical conditioning. Stage 2 presents a new UCS just before presenting the CS.
Term
sensory preconditioning
Definition
two neutral stimuli are paired together and then on the of the neutral stimuli is paired with an UCS. Pair a flash of light and the bell. Then pair the bell with food. Eventually the light will be associated with food, too even without the bell.
Term
operant conditioning
Definition
based on learning the relationship between one's actions and their consequences
Term
law of effect
Definition
proposed by Thorndike that says if a response is followed by an annoying consequence, the animal will be less likely to emit the same response in the future.
Term
positive reinforcement
Definition
the probability that the desired response will be performed is increased by giving the organism something it wants (reward) whenever it makes the desired response.
Term
negative reinforcement
Definition
the probability that the desired response be performed is increased by taking away or preventing something undesirable whenever the desired response is made
Term
escape
Definition
a type of negative reinforcement in which the behavior removes something undesirable
Term
avoidance
Definition
a type of negative reinforcement in which the organism gets a warning that an aversive stimulus will soon occur, and the appropriate response completely avoids the aversive stimulus.
Term
punishment
Definition
the probability that a response will be made is decreased by giving the organism something undesirable whenever the response is made.
Term
discriminative stimulus
Definition
a stimulus condition that indicates that the organism's behavior will have consequences.
Term
partial reinforcement
Definition
a behavior acquired while receiving only occasional reinforcement
Term
fixed-ratio
Definition
the organism receives reinforcement only after a fixed number of responses, eg after every five lever presses an animal gets nom nom
Term
variable-ratio
Definition
the animal receives reinforcement after a varying number of responses. the most resistant to extinction and produces the most rapid response rate f
Term
fixed-interval
Definition
the animal will be reinforced on the first response after a fixed period of time has elapsed since the last reinforcement.
Term
variable interval
Definition
the animal will be reinforced for the first response made after a variable amount of time has elapsed since the last reinforcement.
Term
flooding
Definition
a form of therapy that forces the client to directly experience the feared object (the CS)
Term
implosion
Definition
a type of therapy that forces the client to imagine the feared object (CS)
Term
systematic desensitization
Definition
a type of therapy that forces the client to imagine the feared object (CS) while trying to ensure that the client stays relaxed by using deep relaxation and an anxiety hierarchy
Term
conditioned aversion
Definition
a type of therapy that pairs a desired CS with an aversive UCS
Term
contingency management
Definition
a general name for therapies that attempt to change the client's behavior by altering the consequences of the behavior
Term
behavioral contract
Definition
a written agreement that explicitly states the consequences of certain acts; useful in resolving interpersonal conflicts
Term
time-out
Definition
removing the client from the potentially reinforcing situation before he can receive reinforcement for the undesirable behavior
Term
premack principle
Definition
using a more preferred activity to reinforce a less preferred activity
Term
Problem solving (Thorndike)
Definition
problem solving due to trial and error
Term
problem solving (Kohler)
Definition
problem solving is insightful
Term
Cognitive maps
Definition
animals have mental maps of physical spaces
Term
observational learning
Definition
observing others' behavior can affect your own behavior
Term
preparedness
Definition
animals are prepared to learn connections between certain stimuli
Term
intinctual drift
Definition
instinctual ways of behaving are able to override behaviors learned through operant conditioning.
Term
altruism
Definition
a form of helping behavior where the animal's intent is to benefit other animals at some cost to itself
Term
reproductive fitness
Definition
takes into account the number of offspring that live to be old enough to reproduce... altruism is problematic
Term
inclusive fitness
Definition
takes into account the number of offspring that live to be old enough to reproduce and the number of other relatives who live to reproductive age... altruism is not problematic
