OBJECTIVE MEASUREMENT:
Recording behavioral data unbiased by the observer's feelings, interpretations, or other extraneous factors. 5
|
|
OBSERVATIONAL LEARNING: Learning based on observing the responding of another organism
(and/or its consequences). Observational
learning need not involve imitation (e.g., organisms may
come to avoid aversive stimuli upon seeing what happens when other
organisms produce them). |
|
OBSERVATIONAL LEARNING:
Acquiring new behavior by observing the actions of others. See also imitation.
|
|
OBSERVATIONAL RECORDING: See Direct observational recording. |
|
OBSERVED VALUES:
Values of the selected dimensional quantities that result from the operation of the transducer.
|
|
OBSERVER DRIFT:
A unintended change in the accuracy of an observer's performance.
|
|
OBSERVER DRIFT:
A point at which indexes of agreement between observers begin to diverge. 6
|
|
OBSERVING RESPONSE: A response that produces or clarifies a discriminative stimulus and
that may be maintained by the effectiveness of that stimulus as a
conditioned reinforcer. Observing
responses are sometimes only inferred (as when a pigeon's
head movements are assumed to bring a visual stimulus into view or
better focus), but conditions may be arranged to control them
(e.g., in matching-to-sample the pigeon may be more likely to
observe the sample if a peck on the sample key is required; in a
more explicit arrangement, pigeon's pecks on one key may produce
the stimuli correlated with the components of a multiple schedule
on a second key). |
|
OBTRUSIVE ASSESSMENT:
Measuring performance when the clients or subjects are aware of the ongoing observation.
|
|
OCCASION: An opportunity for a response or some other event, or the
circumstances under which a contingency operates, as when
discriminative stimuli set the occasion
on which responses have some consequence. When a stimulus is said
to occasion a response, the term serves
as a verb and distinguishes responses emitted in the presence of
discriminative stimuli from those elicited by stimuli in a reflex
relation. |
