In Roy's Adaptation Model, which subsystem processes information and responses to stimuli?

• A. Focal Stimuli
• B. Cognator Subsystem
• C. Contextual Stimuli
• D. Residual Stimuli

Answer: (B)

In Roy's Adaptation Model, information processing and the generation of coping responses to stimuli are handled by the Cognator Subsystem. This cognitive-emotional pathway interprets incoming stimuli, processes information, and produces adaptive actions such as perception, learning, judgment, and emotional coping. The other major subsystem, the Regulator, governs physiological regulation through neural, chemical, and endocrine processes, affecting bodily responses rather than cognitive-emotional processing. The stimuli categories—focal, contextual, and residual—describe what triggers the adaptive process, not how information is processed. For example, an alarm sound (a focal stimulus) prompts cognitive appraisal and coping choices managed by the Cognator, while the resulting physiological changes are within the Regulator's domain.
