Cognition refers to various mental processes such as attention, memory, executive functions, comprehension, and perception. Occupational therapists use a dynamic interactional approach to evaluate and treat cognitive impairments. This approach views cognition as the dynamic interaction between a person, their tasks, and their environments. Occupational therapists evaluate clients through standardized and dynamic assessments to understand their cognitive strengths and limitations. Therapists then develop individualized interventions focused on building awareness, teaching strategies, and modifying tasks and environments to improve clients' cognitive performance and participation in daily activities.
