Executive Function:
Stimulus control refers to a differential form or frequency of a performance in the presence of one stimulus which is not evident in the presence of another.
|
|
EXEMPLARS: Examples containing the critical stimulus or response features. For
example, the critical features of a bus are that it transports more
than six people on the ground, has wheels and an engine.
Exemplars would include public busses,
school busses and airport busses. Non-exemplars would be pedal boats, airplanes and horse
drawn wagons. 29 |

EXERCISE, LAW OF:

|
EXPECTANCY: A colloquial term referring to behavior that precedes a predictable
event. Expectancy depends on a history
with respect to that event (it cannot depend on an event that has
not yet occurred). |
|
EXPERIMENTAL ANALYSIS OF BEHAVIOR:
A scientific method designed to discover the functional relation between behavior and the variables that control it. 1, 14

|
EXPERIMENTAL ANALYSIS OF BEHAVIOR:
The method of investigation most commonly used in behavior analysis. The method involves breaking down complex environment-behavior relations into component principles of behavior. The analysis is verified by arranging experimental procedures that reveal the underlying basic principles and controlling variables. This involves intensive experimentation with a single organism over an extended period, rather than statistical assessment of groups exposed to experimental treatments.
|
|
EXPERIMENTAL CONDITION: That part of an experiment in which the independent variable is
present. The independent variable may be only part of the variables
constituting the experimental
condition. Also called treatment or independent variable
condition. |
|
EXPERIMENTAL CONTROL:
A reference to the management or control of different variables in a study, including independent and extraneous variables.
|
|
EXPERIMENTAL DESIGN:
The arrangement of experimental and control conditions so as to permit data-based comparisons about the effects of the independent variable on the dependent variable that will help answer the experimental question.
|
|
EXPERIMENTAL GROUP:
Those subjects exposed to experimental or treatment conditions so as to provide a basis for comparison to the performance of subjects exposed to control conditions.
