Set 2 Flashcards
Escape Extinction
Withholding the removal of an aversive stimulus following a response, when this removal was previously contingent on the response, resulting in a decrease in the probability of the response.
Compound Schedule
A combination of two or more schedules of reinforcement.
Cumulative Record
A graph of the running total number of responses made. New responses are added on to the old total so that the data line can only go up. The slope depends on the rate of responding. The more rapid the responding, the steeper the climb. A horizontal line indicates no responding.
Environment
The entire constellation of stimuli that can affect behavior.
Establishing Operation
An event that increases the efficacy of a reinforcer and increases the likelihood of behavior maintained by that reinforcer.
Fixed Interval Schedule (FI)
A schedule in which reinforcement is arranged for the first response after a set period of time. In fixed-interval schedules, the time is constant from one interval to the next and performance is characterized by a pause after the reinforcer delivery followed by a gradual or abrupt transition to a moderate rate of responding.
Fixed Ratio Schedule (FR)
A schedule in which reinforcement is arranged for the last of a specified number of responses. In a fixed-ratio schedule, the number is constant from one reinforcer to the next; performance is characterized by a break-and-run pattern (pauses after the reinforcer and then a relatively high and constant response rate).
Functional Relation
A relation between two variables in which the manipulation of one variable results in a change in the other.
Response Class
A collection of responses that share a common functional relation with a class of stimuli.
Intermittent Reinforcement
Reinforcement that does not follow every response.
Interval Schedule
A schedule in which reinforcement is arranged for the first response after a period of time and the periods of time vary across schedule completions.
Mixed Schedule
A compound schedule in which two or more component schedules operate in alternation with no stimuli differentially signaling them.
Motivating Operation
An event that alters the effectiveness of a reinforcer and likelihood the responses maintained by that reinforcer. This is an umbrella term that includes both establishing and abolishing operations.
Multiple Schedule
A compound schedule in which two or more component schedules operate in alternation, each in the presence of a particular stimulus.
Pre-Ratio Pause (PRP)
The pause in responding that occurs after reinforcement and before responding on some intermittent schedules (e.g., FR, FI). Sometimes also called a post-reinforcement pause.
