1. intro to different models of sensory processing

sensory integration theory is based on several disciplines

neuroscience, behavioral science, occupational therapy

Other approaches to address sensory processing

SI theory, evaluation, strategies, modifications

Neurobehavioral and organizational processes: sensory processing

unimodal, multimodal (eating)

Neurobehavioral and organizational processes

Sensory processing

Sensory detection + sensory registration

Sensory modulation

Sensory discrimination

Organization of behavior and executive functions

sensory processing

Overarching construct to summarize various neural interactions in the brains associated with incoming sensory signals from the environment or body and subsequent responses resulting from that input

sensory registration in OT

a behavioral orientation to sensory input

sensory registration in neuroscience

firing one or more neurons

sensory registration behavioral science

conscious and non-conscious response

arousal in SI

neural reactions linked to the detection of input activating the sympathetic nervous system

Sensory modulation

requires filtering of sensory info. linked to arousal level

self-regulation in OT

linked to sensory strategies to control the level of alertness

sensory discrimination in OT

refers to interpreting and giving meaning to sensory information

body schema in SI theory

sensory-motor map (contributor to motor planning)

ideation

ability to conceptualize a novel action, generate an idea of what to do

motor planning

ability to organize a novel action, know HOW to do it or the organization of action in space and time

organization of behavior

Ability to organize actions in the present time and space as well as in future time and space

5 assumptions of sensory integration theory:

1. Sensory Nourishment

2. Developmental Process

3. Adaptive Environmental Interaction

4. Existence of Inner Drive and Intrinsic Motivation

5. Neuroplasticity

Sensory nourishment:

sensory input is required for healthy brain function

proximal sensory systems

vestibular, tactile, proprioceptive

Certain types of sensory input are especially influential for

regulation of arousal, formation of attachment, organization of actions

Developmental process:

More complex behaviors rely on the foundation provided by more simple behaviors; development is a spiraling process and sensory integration follows a developmental sequence

Adaptive environmental interaction

A successful environmental interaction both promotes sensory integration, and is evidence of sensory integration

adaptive response

successful responses to environmental challenges

requirements of an adaptive response

Environment that presents sensory information

Challenges to the child that are neither too great nor too small

Sensory integration within the child

Motivation to meet challenge that comes from the child

Organization of a response that meets the challenge

Inner drive

A drive to develop sensory integration is apparent in people

intrinsic motivation

motivation emerges from the satisfaction and enjoyment derived from performance

Neuroplasticity

potential for brain structure or function to change as a result of experience

The importance of adaptive responses in neuroplasticity

1. Neurological structures have the potential for change as results of experience

2. Changes in organization that occur throughout life in response to normal as well as abnormal conditions
