any relatively permanent change in the behavior, thoughts, or feelings of an individual that results from experience.
a phenomenon in which a person gradually becomes more familiar with a stimulus and notices it less and less; in dishabituation, a once-familiar stimulus changes to become unfamiliar, so the person notices the stimulus once again.
an inherited, species-specific, stereotyped, and often relatively complex pattern of behavior.
a preprogrammed response in which a newborn animal looks for a particular kind of stimulus and then carries out the response; the specific stimulus that prompts the response is learned.
the learning progress whereby an originally neutral stimulus becomes associated with a particular psychological or emotional response that the stimulus did not originally produce.
an automatic physiological or emotional response to an unconditional stimulus.
an originally neutral stimulus that later will elicit a physiological or emotional response.
a response similar to the unconditioned response, but that is elicited from the conditioned stimulus rather than the unconditioned stimulus.
a phase of learning when the probability of the conditioned response decreases over time, eventually approaching zero.
a response to the observed similarity of a stimulus to the conditioned stimulus, which increases the likelihood that the conditioned response will occur following presentation of the stimulus.
a response to the observed difference between a new stimulus and the original conditioned stimulus, which makes it less likely that the new stimulus will lead to a conditioned response.
the process of increasing or decreasing the likelihood that an individual with produce an active behavior (an operant) as a result of interacting with the environment.
a stimulus event that increases the probability that the operant associated with it will be repeated.
a positive stimulus even that follows an operant and strengthens the associated behavioral response
the effect of a positive reinforcer (stimulus event) soon after the operant (response)
the effect of the removal or cessation of an unpleasant stimulus, such as physical or psychological pain or discomfort
an unpleasant stimulus event that is removed following an operant response, thereby leading to an increased probability that the operant will be repeated
the effect of the delivery of a stimulus event that decreases the probability of an associated response; results from either presenting an unpleasant stimulus or removing a pleasant one.
the use of punishment as a means of encouraging an individual to try to escape of avoid a situation
the goal of aversive conditioning; an individual learns to stay away from something.
a learned behavior in which an individual gives ip trying to escape from a painful situation after repeatedly failing to escape.
gradient of reinforcement
a phenomenon in which increases in the length of time between operant and reinforcer directly decrease the effect of the reinforcement.
a stimulus that gains reinforcing value through association with a primary reinforcer
a method for shaping behavior by gradually reinforcing operants that are increasingly more similar to the desired behavior.
a learning program in which reinforcement always follows a particular operant behavior
an operant-conditioning program in which a given operant is reinforced at some times but not at other times.
