Sensory Processing, by Cynthia Kim (Musings of an Aspie blog). A very thorough article linking to several others she has written on the subject, titled Sensory Sensitivities and Atypical Sensory Processing, The Difference Between a Sensory Sensitivity and Disliking Something, Sensory Sensitivities: Understanding Triggers, Sensory Diet, Tactile Defensiveness, Sensory Seeking, Sensory Sensitivities Survey Responses, Lost in Space, and Interoception. Very detailed and very readable!
