Sensation Integration Flashcards
Sensory Integration Dysfunction (SID)
Jane Ayers
Used as a specific theory and intervention approach that emerged within the OT field
We CANNOT observe sensory integration
We CAN observe behavior
We hypothesize on theory of neuroscience that integration occurs
Integration
The brain’s ability to effectively manage and interpret information in an organized manner
Highlights sensory processing of information that goes beyond the five senses (+ movement and balance sense)
Dynamic process of interactions organizing info externally and internally
5 senses
They tend to like music Feeding is a difficult issue Grinding teeth Mouth exploring for sensory input Don't like finger pain, sand, crafts, etc.
Dysfunction
The brain cannot analyze, organize, connect, or integrate sensory messages
Exaggerated responses to non-threatening situations
Cannot balance sensory information appropriately
Modulation
Balance of integration and dysfunction
The brain’s regulation of messages by facilitating or inhibiting responses
The NS responds to some stimuli while ignoring others; therefore, an adaptive response is performed
Consistent therapy is necessary for child’s success
Habituation
The process that represents to the NS that something familiar has occurred
Sensitization
The NS’s mechanism that enhances potentially important stimuli; detects harm or danger in a situation
HIGH (habituation)
POOR registration
Sensation SEEKING
LOW (sensitization)
SENSITIVITY to stimuli
Sensation AVOIDING
Sensation seeking
The combination of high neurobiological thresholds and an active self regulation strategy
Enjoys and generates extra sensory input
Adding spice to already seasoned food
Low registration
The combination of high neurological thresholds and a passive self-regulation strategy
Notices sensory stimuli much less than others
Doesn’t get jokes as quickly
Sensation avoiding
The combination of low neurological thresholds and an active self regulation strategy
Bothered by input more than others
Only will eat familiar foods
Sensory sensitivity
The combination of low neurological thresholds and a passive self regulation strategy
Detects more input than others
Afraid of heights and experiencing discomfort
Level I Sensory Integration
Primary sensory system
2 mos
Tactile sense (touch) Vestibular sense (balance and movement) Properties sense (Body px) Visual and auditory sense
Level II Sensory Integration
Foundation of perceptual motor
6-24 mos
Body perception
Bilateral coordination
Lateralization
Motor planning
Level III Sensory Integration
Perceptual motor
3 years old
Auditory processing
Visual perception
Eye-hand/foot coordination
Visual motor coordination
Level IV Sensory Integration
Academic readiness
6 years old
Academic skills
Complex motor skills
Regulation of behavior
Organized behavior
SMD Sensory
Over Responsiveness
Behavioral characteristics associated with sensory over-responsiveness may include…
Aggression Impulsivity Irritability Fussiness Unsociable Avoids group activities Upset by transitions
General Characteristics SMD
Over-reactiveness
Mud or glue on their hands
Crawling, walking barefoot
Feeling crumbs in or around mouth
Having hair, fingernails, or toe nails cut
Food textures
Background noises when trying to concentration
Playing in swings
Fragrances from perfume
SMD Sensory
Under Responsiveness
Indicators of sensory under-responsive behaviors…
Doesn’t cry when hurt or injured
Prefers sedentary activities
Often unaware of what is happening around them
Does not notice food on or around their mouth
Unaware of body sensations (hunger)
