EXPERIMENTAL GROUP:
A group of subjects exposed to the presumed crucial value of the independent variable.
|
|
EXPERIMENTAL INTERACTION:
One experimental condition affects the results of another.
|
|
EXPERIMENTAL METHOD:
A general reference to the procedures for arranging, conducting, and interpreting experiments. In the case of a particular experiment, the actual procedures used, including measurement, experimental design, and data analysis. See Box 1.2.
|
|
EXPERIMENTAL PHASES:
Those portions of an experiment in which the experimental condition is present and potentially in contact with subject's behavior.
|
|
EXPERIMENTAL QUESTION:
A brief but specific statement of what the researcher wants to learn from conducting the experiment.
|
|
EXPERIMENTAL SETTING:
An inclusive reference to all features of the environment in which both control and experimental conditions will be implemented. May sometimes refer to all variables other than the independent variable.
|
|
EXPERIMENTAL SIGNIFICANCE: In determining experimental
significance we ask what the behavior would be if the
experimental intervention had not occurred. Did the treatment
result in a meaningful change in the behavior? 22 |
|
EXPERIMENTAL SPACE: The enclosure in which an operant conditioning experiment is
carried out and in which a simple, easily repeatable performance
can be reinforced and measured is referred to as an experimental space. An experimental space in which there is a lever which
a rat can press, or a key which a pigeon can peck, is frequently
referred to as a Skinner Box because it was first developed by B.
F. Skinner. |
|
EXPLANATORY FICTION: Is a statement that has the form of an explanation but whose
"cause" is really the same as its "effect." In an explanatory fiction the same set of facts is
described both by the behavior that is supposedly being explained
and by the explanation. An example is, "Sarah doesn't read as well
as you would expect from her reading aptitude scores because she is
an under-achiever in reading." Both "cause" and "effect" describe
the difference between Sarah's aptitude scores and reading
performance. |
|
EXPLANATORY RESEARCH:
A style of research in which the primary goal is to understand the nature or mechanisms of the relationship between the independent and dependent variable. See Demonstration research
