First, there is the unified principle of reinforcement: The same conditioning process is responsible for selecting respondent and operant relations, and, in both cases, the reinforcing stimulus (US) strengthens relations between stimuli and responses that occurred systematically in a contiguous way.
If we defend, for instance, that the unit of selection in an operant contingency is a relation between a response class and a reinforcing stimulus (R-US), and that the unit of selection in a respondent contingency is a relation among stimuli (US-CS), any attempt of unification of the processes would be impossible.
A reinforcing stimulus following some behavior increases the likelihood of that behavior occurring in the future.
According to this "formula," the occurrence of some behavior is highly probable (other conditions being present) when a certain antecedent (discriminative) stimulus is present as the result of a past history of the behavior being contingently followed by a reinforcing stimulus under some schedule of reinforcement.
A modified non-exclusionary timeout, the timeout ribbon procedure, combines contingent observation and the removal of a reinforcing stimulus
The therapist acts as an eliciting stimulus of consumer respondent behavior, a discriminative stimulus for operant behavior, and a reinforcing stimulus
for effective behavior.
the lever) was predictive of a strengthened reinforcing stimulus (i.
Next, if the absence or removal of lever B was serving as the reinforcing stimulus, then it would seem logical that the presence of lever B would serve as an inhibitory stimulus.
If we consider the relatively simple situation where only one operant response is to be examined and the antecedent stimulus conditions are constant, there are at least two things we may specify: the number of responses that must occur, and the time that must elapse before a reinforcing stimulus is presented contingent upon the next instance of the operant response.
In most case the establishing operation (see below) of food deprivation has been used, and delivery of small amounts of palatable food have been used as the response-contingent reinforcing stimulus.
In the laboratory, specific learning histories are established such that subjects have more than one response in their repertoire that has produced a specific reinforcing stimulus
For example, the Picture Exchange Communication System (PECS; Bondy & Frost, 1994) avoids the use of verbal prompts in the first stages of training to reduce the likelihood that responding will come under the stimulus control of the verbal prompts as opposed to the reinforcing stimulus
The process involves the occurrence of responses followed by the presentation of a reinforcing stimulus
, the outcome of which is an increase in the frequency of occurrence of responses belonging to the same class.
In a conditional discrimination trial a reinforcing stimulus
is presented for choosing one of the comparisons in the presence of a given sample and not in the presence of another sample.
The definition of the unit specifies the relations of the sample (first term) and comparison (second term) stimuli with the defined response (third term) and a reinforcing stimulus
