If the object is missing, and the response is "about" that object, what is the discriminative stimulus for that response?
The objective of the experiment was to examine whether an instruction that guided the participant to emit a vocal response with a qualifying autoclitic of assertion and prediction "is", between the presentation of a conditional stimulus and the choice of discriminative stimulus in MTS tasks, would influence the formation of conditional discriminations and the formation of stimuli equivalence.
The right hand of Figure 2 presents mean percentage of correct responses to the key discriminative stimulus Z throughout the 8 trials of training in context A in groups I and NI.
For example if a client is having difficulties with pronouncing certain words or longer expressions, the model discriminative stimulus provides a standard that can be used for correcting the problem.
Researchers established a clear discriminative stimulus with the students, removed that stimulus (and all access to reinforcement) when students displayed the targeted inappropriate behavior and returned that stimulus after a set amount of time.
Participants received instrumental discriminative training in which giving a specific instrumental response (R1 or R2) in the presence of a discriminative stimulus (e.g.
Skinner (1957) defined the tact as "a verbal operant in which a given response form is evoked (or at least strengthened) by a particular object or event or a property of an object or event." According to Skinner's technical analysis, the unique relation to a discriminative stimulus, rather than to a specific establishing operation, is obtained by (1) many different reinforcers or (2) generalized reinforcers.
To this end, we highlight studies published in the Pavlovian associative literature as well as in at least one seldom-cited study published in the Journal of the Experimental Analysis of Behavior (JEAB) supporting the view that CS relations embedded in the three-term operant contingency [SD]: [R]-[S.sup.R+]) can act independently of the discriminative stimulus functions of the [S.sup.D]--and appear to be neither necessary nor sufficient for sustaining operant discriminative control.
Figure 2 shows that clinicians' most significant activities during assessment were: (a) collecting information or assessing (repetition of discriminative stimulus + discriminative stimulus + ...

A man who walks into his house and announces to his wife that "Bhutto was assassinated yesterday" (a tact) has a conditioning history of talking about Bhutto with his wife, a current stimulus that may include an announcement on the radio, TV news, or a newspaper, and the presence of his wife who is the audience (discriminative stimulus).
Time delay procedures typically involve the presentation of a discriminative stimulus (e.g., a flashcard with the word "LAUNDRY" on it) followed by the delivery of an instructional cue (e.g., "What word is this?") followed by the provision of the controlling prompt (i.e., stating the correct response; e.g., "laundry").
