3. sensory processing challenges pt 2

sensory discrimination

includes detection and recognition, linked to attention, cog, and memory

detection

ability to discriminate between a positive stimulus and null stimulus

recognition

ability to distinguish between different stimuli

body schema

internal representation of our body structure and how our body functions

body awareness

conscious awarness

praxis in neuroscience

ability to plan and perform skilled movements using a movement scheme based on a stored complex representation

praxis in peds

developmental coordination disorder and dyspraxia

supplementary motor area

responds to proprioceptive input, active before movement begins. supports feedforward motor planning

pre-motor

responds to visual input and somatosensory input. sets readiness potentials in the body, head, and eyes for fine motor skills

motor planning

feedback, feedforward continuum

feedback

stationary (tactile, proprioceptive, visual systems)

feedforward

moving (vestibular, proprioceptive, visual systems)

somatodyspraxia

related to tactile discrimination and proprioceptive processing. motor planning difficulties (feedback)

bilateral integration and sequencing disorder

related to vestibular and proprioceptive processing. bilateral motor coordination difficulties. feedforward motor planning

Sensory processing of children with developmental coordination (DCD)

Somatosensation: children with DCD performed poorer on tests measuring tactile processing and visual motor skills

Praxis and ASD

Praxis is strongly correlated with social, communicative, and behavioral impairments characteristic (dyspraxia a core feature)

Imitation is important in the development of

interpersonal relations, sharing, language, intention, and empathy
