Since birth, infants develop the ability to perceive a wide range of intersensory relations among various kinds of amodal temporal information. This study addresses the development of the ability to perceive duration-based intersensory relations. Three groups of infants, four, seven and 10 months old, participated in two trials of an intersensory…

Infants with visual impairment often require additional interaction from adults to reinforce behaviors that lead to competency at mealtimes, but parental and professional confidence in teaching these skills is often limited. In the following collective case study, the authors, a speech/language pathologist (S/LP), occupational therapist (OT), and…

This study summarises the findings based on two case study sensory gardens in the United Kingdom, in terms of the educational development and social interaction of children with special needs and the staff who care for them. The aim was to observe and record the users' behaviour when engaging with features in the sensory garden. The data…

In normal-hearing children the latency of the P1 component of the cortical evoked response to sound varies as a function of age and, thus, can be used as a biomarker for maturation of central auditory pathways. We assessed P1 latency in 245 congenitally deaf children fit with cochlear implants following various periods of auditory deprivation. If…

One of the important nutrients during pregnancy is vitamin A or related compounds called retinoids. Although it is well-known that vitamin A deficiency may be detrimental to foetal development, overdosage of retinoids might cause developmental defects, particularly affecting the central nervous system development of the foetus, causing hindbrain…

Research is reviewed regarding cluttering (a speech language disorder typified by problems of fluency, articulation, receptive and expressive language, and perceptual motor skills), and the concept is advanced that cluttering is a syndrome of learning disability symptoms. (CL)

This article presents a case study of a Japanese adolescent with autism who strongly perceived inanimate things (Kanji characters) as real persons. Physiognomic perception is investigated as a characteristic mode of autism, and its effects are discussed. It is concluded that the poor cognitive-language ability of some autistic people may shape…

Over half the world's population speaks a tone language, yet infant speech perception research has typically focused on consonants and vowels. Very young infants can discriminate a wide range of native and nonnative consonants and vowels, and then in a process of "perceptual reorganization" over the 1st year, discrimination of most…

This study compared improvements in visual function of 20 Spanish children with low vision, ages 4 to 6 years. Children received either the Barraga and Morris program or the Frostig program, or placebo control or no treatment. No significant differences between treatment groups were found. (DB)

Highlights similarities and differences between the art making of normally developing and mentally retarded individuals. Defines pathological art as outsider art that can never be creative in the sense of relating to the artistic domain and engaging in a creative dialog with other artists that shape that domain. (MJP)

Presents a series of pictures drawn by an autistic adult over a period of years. The pictures represent recollections of a day in his childhood. This representation is notable because of its consistent theme, as well as its reflection of the ability to reexperience and enjoy pleasant past memories. (MJP)

Reviews two long-term case studies examining the art produced by two artistically gifted Down Syndrome patients. Their work shows a unique personal style characterized by flat, nonperspective compositions, canonical and mixed profile shapes, and symmetry. Both artists depict androgynous persons in their untutored drawings. Includes drawing samples…

Reviews the work of neurobiologist, David Marr, concerning artistic ability and autism. Summarizes Marr's theory of perceptual vision illuminating the relationships among object, observer, perceptual process, and image. Briefly reviews the cases of four autistic people with extraordinary drawing skills. (MJP)
