Stimulus control is said to occur when an organism behaves in one way in the presence of a given stimulus and another way in its absence. For example, the presence of a stop sign increases the probability that "braking" behavior will occur. Typically such behavior is brought about by reinforcing the behavior in the presence of one stimulus and omitting reinforcement in the presence of another stimulus. Many theorists believe that all behavior is under some form of stimulus control. Verbal behavior is a complicated assortment of behaviors with a variety of controlling stimuli. ==Characteristics== The controlling effects of stimuli are seen in quite diverse situations and in many aspects of behavior. For example, a stimulus presented at one time may control responses emitted immediately or at a later time; two stimuli may control the same behavior; a single stimulus may trigger behavior A at one time and behavior B at another; a stimulus may control behavior only in the presence of another stimulus, and so on. These sorts of control are brought about by a variety of methods and they play a large role in systematic accounts of behavioral processes.〔Catania, A. C. "Learning" 3rd ed, 1992, Prentice Hall, Englewoood Cliffs, NJ.〕 In simple, practical situations, as if, for example if one were training a dog, one might aim for a restrictive form of stimulus control, such that * The behavior occurs immediately when the conditioned stimulus is given. * The behavior never occurs in the absence of the stimulus. * The behavior never occurs in response to some other stimulus. * No other behavior occurs in response to this stimulus. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「stimulus control」の詳細全文を読む スポンサード リンク
