The instructor who asks the class, "What is a

Learning about a
discriminative stimulus that was a consistent predictor of the relationship between an instrumental response and an outcome was found to be context dependent when training was conducted within a context that was informative to solve an alternative discrimination (group I), but not when training was conducted within a non-informative context (group NI).
Advantageously, the timeout ribbon procedure has certain set characteristics (e.g., a reinforcement rich time-in, a conspicuous
discriminative stimulus, targeting low-intensity inappropriate behaviors) and empirical support.
During the Pre period, the tank and the plane were presented without the
discriminative stimulus for 4 s (see top panel of Figure 1).
The control of appetitive instrumental responding does not depend upon classical conditioning to the
discriminative stimulus. The Quarterly Journal of Experimental Psychology Section B: Comparative and Physiological Psychology, 33, 21-31.
The registers in the phase of assessment seemed to have a predominance of point-event categories (mainly

The mand is a

Consider a trial with set size 1: The experimenter says "2" and the subject responds with "2." This can be interpreted and symbolized in the usual way in terms of the three-term contingency: The experimenter's response "2" is a verbal
discriminative stimulus ([S.sup.DV]) that occasions the verbal response "2" ([R.sup.V]).
These results suggested that the presence of a communication card may function as a
discriminative stimulus for a specific topography of manding, but that training with the card did not inhibit the use of other mands when the card was absent.
