In contrast, unsupervised classification techniques such as finite mixture…

In this article, we examine the extent to which children with autism and children with learning difficulties can be discriminated from their responses to different patterns of sensory stimuli. Using an adapted version of the Short Sensory Profile (SSP), sensory processing was compared in 34 children with autism to 33 children with typical…

To identify classroom behaviors that differentiate primary-level students with learning disabilities (LD) from their nondisabled peers, two scales of 83 items each were devised and piloted. Two subscales and 18 individual items were found to discriminate students later classified as LD and those referred but not subsequently classified as LD.…

A discriminant analysis was performed to ascertain what psycho-educational assessment variables made the greatest predictive contribution to the classification of high school students referred for Child Study Team evaluation. Thirty-nine students classified as learning disabled were compared to 47 classified as ineligible for special services.…
