Chapter 2 Flashcards
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 before some intervention
case study approach
a descriptive research approach that involves intensive examination of one or few individuals
changing-criterion design
a type of single-subject design in which the effect of the treatment is demonstrated by how closely the behavior matches the criterion that is systematically altered
Comparative Design
a type of control 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 experiment in which, at its simplest, subjects are randomly assigned to either an experimental 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
Covert Behavior
behavior that can be subjectively perceived only by the person performing the behavior. Thoughts and feelings are covert behaviors.
Cumulative Recorder
a device that measures total number of responses over time and provides a graphic depiction of the rate of behavior
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
Deprivation
the prolonged absence of an event that tends to increase the appetitiveness of that event
Descriptive Research
research that focuses on the describing the behavior and the situation within which it occurs
Duration
the length of time that an individual repeatedly or continuously performs a certain behavior
Establishing Operation
a procedure that affects the appetitiveness to aversiveness of a stimulus
