Ayres's theoretical framework for what she called Sensory Integration Dysfunction was developed after six factor analytic studies of populations of children with learning disabilities, perceptual motor disabilities and normal developing children. [81] Ayres created the following nosology based on the patterns that appeared on her factor analysis:
Alice in Wonderland Syndrome (AIWS), also known as Todd's Syndrome or Dysmetropsia, is a neurological disorder that distorts perception.People with this syndrome may experience distortions in their visual perception of objects, such as appearing smaller or larger (), or appearing to be closer or farther than they are.

Some children appear to be unable to process tactile input. For example, they may seem insensitive to pain or dislike being touched.
DAMP is diagnosed on the basis of concomitant attention deficit/hyperactivity disorder and developmental coordination disorder in children who do not have a severe learning disability or cerebral palsy.

Social workers obtain literacy history from the home, and then observe the child during classroom activities, they look for social interactions. Psychologists review a child's phonological memory by having him or her repeat series of words, numbers, letters, and sounds. They also look for response from the child to environmental and social factors.
This has been tested by having children with and without reading disabilities perform on tasks related to the transient systems, where the children with reading disabilities did very poorly. It has also been found in postmortem examinations of the brains of people with reading disabilities that they have fewer neurons and connections in the ...
