Sensory Development
Generally speaking, children who have efficient sensory systems are happy, engaged, and learn in numerous settings.
However, when children have difficulty integrating sensation many daily activities are impacted. "A.Jean Ayres, PhD, OTR, the pioneer of sensory integration theory, states that children who have poor sensory integration may seem typical in many ways, and they often have average or above average intelligence.”
Although they may have strengths in many areas they may also struggle with daily life and routines in the areas of play and social skills, movement and coordination, daily activities, and self-expression.
Sensory integration can be observed in all areas of development.
For example:
- Calming in response to rhythmic rocking or a parent’s touch
- Lifting a head up in response to sound or to play with someone
- Rolling, crawling, or walking to get an interesting toy
- Enjoying a varied diet rich with foods of all different flavors and textures
- Having an interest in exploring new and various environments
- Seeking and enjoying all sorts of playful movement
The following contain a list of behaviors that are signs of good sensory integration in children. The lists are organized by functional areas and not by importance. Make sure to check behaviors as your child is able to consistently demonstrate them.
One or two missing behaviors should not cause alarm. It is crucial to look at your child’s overall tendencies and clusters of behavior and acknowledge that all children develop at their own variable rate. However, if your child is frequently and consistently not demonstrating more than a few of the listed items in each AGE category, discuss your concerns with your healthcare professional.
