Definition
| The normal frequency of a behavior before some intervention. |

|
Term
|
Definition
| A descriptive research approach that involves intensive examination of one or a few individual. |
|
|
Term
| Changing-criterion Design |
|
Definition
| 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 systematically altered. |
|
|
Term
|
Definition
| A type of control group design in which different species constitute one of the independent variables. |
|
|
Term
|
Definition
| A predictive relationship between 2 events such that the occurrence of one event predicts the probable occurrence of the other. |
|
|
Term
|
Definition
| A type of experiment in which, at its simplest, subjects are randomly 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. |
|
|
Term
|
Definition
| 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." |
|
|
Term
|
Definition
| A device that measures total number of responses over time and provides a graphic depiction of the rate of behavior. |
|
|
Term
|
Definition
| That aspect of an experiment that is allowed to freely vary to determine if it is affected by changes in the independent variable. |
|
|
Term
|
Definition
| The prolonged absence of an even that tends to increase the appetitiveness of that event. |
|
|
Term
|
Definition
| Research that focuses on describing the behavior and the situation within which it occurs. |
|
|
Term
|
Definition
| The length of time that an individual repeatedly or continuously performs a certain behavior. |
|
|
Term
|
Definition
| A procedure that effects the appetitiveness or aversiveness of a stimulus. |
|
|
Term
|
Definition
| The relationship between changes in an independent variable and the changes in a dependent variable; a cause-and-effect relationship. |
|
|
Term
|
Definition
| That aspect of an experiment that is made to systematically vary across the different conditions in an experiment. |
|
|
Term
|
Definition
| The force or magnitude of a behavior. |
|
|
Term
|
Definition
| The measurement of whether or not a behavior occurs within a series of continuous interval, (Note that the number of times that the behavior occurs within each interval is irrelevant.) |
|
|
Term
|
Definition
| The force or magnitude of a behavior. |
|
|
Term
|
Definition
| A type of single-subject design in which a treatment is instituted at successive points in time for 2 or more persons, settings, or behaviors. |
|
|
Term
|
Definition
| A descriptive research approach that involves the systematic observation and recording of behavior in its natural environment. |
|
|
Term
|
Definition
| Behavior that has the potential for being directly observed by an individual other than the 1 performing the behavior. |
|
|
Term
|
Definition
| The frequency with which a response occurs in a certain period of time. |
|
|
Term
|
Definition
| A particular instance of behavior. |
|
|
Term
|
Definition
| A type of single-subject design that involves repeated alterations between a baseline period and a treatment period. |
|
|
Term
|
Definition
| The prolonged exposure to (or consumption of) an event that tends to decrease the appetitiveness of that event. |
|
|
Term
|
Definition
| A type of single-subject design in which behavior in a baseline condition is compared to behavior in a treatment condition. |
|
|
Term
|
Definition
| A research design that requires only 1 or a few subjects in order to conduct an entire experiment. Also known as "single case" or "small n" designs. |
|
|
Term
|
Definition
| The extent to which events are situated close to each other in space. |
|
|
Term
|
Definition
| The amount of time required to perform a complete episode of a behavior from start to finish. |
|
|
Term
|
Definition
| Any event that can potentially influence behavior. (The plural stimulus is "stimuli.") |
|
|
Term
|
Definition
| The extent to which events occur close enough together in time. |
|
|
Term
|
Definition
| The measurement of whether or not a behavior occurs within a series of discontinuous intervals. (The number of times that it occurs within each interval is irrelevant.) |
|
|
Term
|
Definition
| The physical form of a behavior. |
|
|
Term
