The dynamic interactional model of cognitive rehabilitation emphasizes that cognition is a continuous product of the dynamic interaction between the individual, task, and environment. Individual factor includes structural capacity (including physical limitation), strategies (including organized approach/routine/tactics), metacognitive processes (knowledge and regulation of own cognitive processes and capacities) and learner characteristics such as motivation and knowledge. These individual factors interact with other factors during information processing and learning. Information processing is broadly divided into three stages: input, elaboration, and output. Each stage requires specific sets of cognitive skills, and the control functions (executive function, metacognition) influence all stages. Type of environment (social, physical, cultural) influences an individual’s ability to process information and adapts to demands. It can mediate processing between task and the individual. The task mainly involves surface characteristics (e.g., number of items, type of stimuli, active postural requirement) and conceptual characteristics (e.g., underlying skills and strategies used to perform the task, underlying meaning of task). Within this dynamic interactional model of cognitive rehabilitation, assessments are divided into two types. Static assessments are used to identify and quantify cognitive deficits. Dynamic assessments are used to identify and specify the conditions that have the greatest influence on performance. They are also used to identify learning potential (awareness, responsiveness, etc.). For intervention, this model suggests that a functional approach is more appropriate for client with poor learning potential, and a multiple-context approach is more appropriate for patients with potential for learning.

Domain of occupation
This model is developed specifically for adults with brain injure, and so clients with developmental and mental disabilities may not be applicable.
