An event that an organism will seek out

An event that an organism will avoid

The normal frequency of a behavior before some intervention

A descriptive research approach that involves intensive examination of one or a few individuals

type of single-subject design in which the effect of the treatment is demonstrated by how closely the behavior matches a criterion that is systematically altered.

A type of control group design in which different species constitute one of the independent variables

A predictive relationship between two events such that the occurrence of one event predicts the probable occurrence of the other.

A type of experiment in which, at its simplest, subjects are randonly assigned to either an experimental ( or treatment) group or a control group; subjects assigned to the experimental group are exposed to a certain manipulation or treatment, while those assigned to the control group are not

Behavior that can be subjectively perceived only by the person performing the behavior. Thoughts and feelings are covert behaviors

A device that measures total number of responses over time and provides a graphic depiction of the rate of behavior.

That aspect of an experiment that is allowed to freely vary to determine if it is affected by changes in the independent variable.

The prolonged absence of an event that tends to increase the appetitiveness (an event that an organism will seek out) of that event.

Research that focuses on describing the behavior and the situation within which it occurs

The length of time that an individual repeatedly or continuously performs a certain behavior

A procedure that affects the appetitveness or aversiveness of a stimulus

The relationship between changes in an independent variable and changes in a dependent variable; a cause-and-effect relationship.

That aspect of an experiment that is made to systematically vary across different conditions in an experiment

The force or magnitude of a behavior

The measurement of whether or not a behavior occurs within a series of continuous intervals. (The number of times that it occurswithin each interval is irrelevant.)
