ABSTRACT
Stimulus control therapy (SCT) for insomnia is based primarily upon an operant conditioning model of the development and maintenance of insomnia in which falling asleep is conceptualized as an instrumental act emitted to produce the reinforcement, sleep. Difficulty in falling asleep, then may be due to inadequate stimulus control (1). This could be either because of the lack of discriminative stimuli that facilitate sleep or the presence of stimuli that are associated with activities that interfere with sleep.
