NEUROLOGICAL THRESHOLDS!
“the nervous system’s responsiveness to stimuli”
How does a child respond to the world around them? Sights? Sounds? Touch? Smells? Movement? Body position? Taste?
A low threshold means that a low amount or intensity of stimuli is needed as the nervous system is easily activated for awareness and response. A child is described as hyperresponsive.
A high threshold means more intense stimuli is needed before the nervous system responds. A child is described as hyporesponsive.
Sensitization is the process that enhances the awareness of important stimuli, screening anticipated harm or danger in the environment while engaged in play or learning. We need to be able to respond quickly to risky situations that could hurt us.
Habituation is the process of recognising familiar stimuli that does not require further attention, allowing focused attention of the task at hand without becoming distracted, agitated or inattentive. There is comfort and security found in familiar sights, sounds, people, routines, textures, schedules and expectations that reassure us.
Modulation is the balance of activation needed so that a child can be alert to selected information while screening out other stimuli in order for functional participation in everyday life. The child selects the appropriate responses to environmental cues.
The children we see for occupational therapy may have difficulty processing sensory information … eg. alert to sensory information that interferes with tasks, unaware of sensory information, perceives something as dangerous when it isn’t, can’t get enough sensory information.
I’m sharing more about sensory processing and sensory based activities this month on so make sure you take a look. In the meantime, don’t forget to grab your FREE ticket to the Sensory Summit Online Conference (Oct 27-29). Let me know if you want a link! 🔗
