What is Sensory Defensiveness?

Sensory Defensiveness is a constellation of symptoms that are the result of aversive or defensive reactions to non-noxious stimuli across one or more sensory modalities. It is an over reaction of our normal protective senses. Individuals with sensory defensiveness have their own response style. There may be patterns of avoidance, sensory seeking, fear, anxiety or even aggression. 

Social Emotional Disorders Related to Sensory Defensiveness are the pattern of learned behaviors that create habits and interaction styles that are protective and defensive in nature. These stress and anxiety reaction can continue after the primary symptoms of sensory defensiveness are no longer present.
