Sensory Integration Theory

Occupational Therapy Delineation Model of Practice for Children with Attention Deficit Hyperactivity Disorder

• This model of practice is based on the theoretical concepts relating to the child, environment, task, and the interaction among these key factors and the child’s participation in different occupations. A goodness-of-fit of those factors is necessary for successful participation in occupations.

Dynamic Systems Theory Model of Visual Perception Development

• The dynamic system theory model of visual perception aims to facilitate practitioners in understanding the development of visual perception from a dynamic systems theory perspective. This model views vision and ocular motor abilities as a part (instead of the foundation) of the complex interaction of components of the experience of vision.

Frame of Reference for Visual Perception

• This frame of reference adapts a top-down approach to identify visual perceptual factors that limit an individual’s daily participation, and adaptive and compensation approaches are used to facilitate engagement in meaningful occupation. It uses theories from cognition, developmental psychology, education, and Warren’s developmental hierarchy of visual perceptual skills. Visual Perceptual skill development is viewed to be developed from a hierarchy, starting from oculomotor control, visual fields, visual acuity.

Conceptual Model for Performance in Handwriting

• The Conceptual Model for Performance in Handwriting views that handwriting is important for one’s work and/or education domains of occupations. It considers the performance components, performance areas (functional performance), performance contexts, and the interactive relationship among them. Prerequisites to handwriting include performance components in sensory, perceptual, motor cognitive, and language functions, as well as integrations of these components.
