Chapter 2 Flashcards
abolishing operation
a procedure that decreases the appetitiveness or aversiveness of a stimulus
appetitive stimulus
an event that an organism will seek out
aversive stimulus
an event that an organism will avoid
baseline
the normal frequency of a behavior prior to an intervention
changing-criterion design
a type of single-subject design in which the effect of the treatment is demonstrated by how closely the behavior matches a criterion that is systemically altered
Comparative design
A type of group design in which different species constitute one of the independent variables
Contingency
A predictive relationship between two events such that the occurrence of one event predicts the probable occurrence of the other
Control group design
A type of group design in which, at its simplest, subjects are randomly assigned to either an experimental (or treatment group) or a control group
Covert behavior
Behavior that can be subjectively perceived only by the person performing the behavior. Thoughts and feelings are covert behaviors. Also known as private events or private behavior.
Cumulative recorder
A device that records total number of responses overtime and provides a graphic depiction of the rate of response.
Dependent variable
That aspect of an experiment That is allowed to freely vary to determine if it is affected by changes in the independent variable
Descriptive research
Research that focuses on describing behavior and the circumstances behavior and the circumstances within which it occurred
Duration
The total amount of time that an individual repeatedly or continuously performs a certain behavior
Establishing an operation
A procedure that increases the appetitiveness or aversiveness of the stimulus
Experimental research
A research method in which one or more independent variables are systemically varied to determine their effect on a dependent variable
