Are High- and Low-Functioning Autism Meaningful Descriptions? This perspective, rooted in the psychoanalysis of Sigmund Freud and Jacques Lacan, describes autism as a singular subjective structure that is not reducible to the major structures of subjectivity elaborated in psychoanalysis so far: neurosis, perversion, and psychosis.

This review considers how atypical perceptual category learning can affect cognitive development in children with ASD and how atypical categorization may contribute to many of the socially problematic symptoms associated with this disorder. A more systematic and - at best - standardized assessment for hearing related sequelae of trauma is needed for a better understanding of the underlying pathophysiology and for developing more tailored treatment approaches as well. Hyperlexia, which, is distinguished by precocity rather than, dent level of skill, has also been frequently repor, Generally, a single special skill exists but, in some. There are also known cases of creation of savant skills over a lifetime, resulting in damage of the left hemisphere. By investigating a worldwide sample of tinnitus patients derived from the Tinnitus Research Initiative (TRI) Database, we aimed to identify differences in demographic, clinical and audiological characteristics between tinnitus patients with and without preceding trauma. Behav. Although Treffert's term, "savant syndrome," has achieved wide currency, many other labels have been proposed, and the older term, "idiot savant," remains in use, in both the professional and popular literature.

Specifically, it refers to being an “island of genius” in a sea of deficits, as the giftedness contrasts significantly with the person’s overall disability.

This explains the development of a special skill with reference to the normal population and the low incidence rate among the mentally retarded. This may be a reflection of a very low correlation between the abilities necessary for these skills and the abilities measured by an IQ test. Assessment included demographic data, tinnitus related clinical data, audiological data, the Tinnitus Handicap Inventory, the Tinnitus Questionnaire, the Beck Depression Inventory, various numeric tinnitus rating scales, and the World Health Organisation Quality of Life Scale (WHOQoL).

Still other childr, showed music ability, arithmetical genius or precise. In, diagnosis of mental retardation, the incidence of savant, study surveyed 583 facilities, and found a prevalence, rate of 1.4 per 1000, or approximately double the Hill, Whatever the exact figures, mental retardation an, other forms of developmental disability are more, common than autistic disorder, so a reasonable, estimate might be that approximately 50 per cent of, persons with savant syndrome have autistic disorder, and the other 50 per cent have other forms of, developmental disability, mental retardation or other, have savant syndrome and not all persons with savant, growth in the right brain as a result of impaired, male : female ratio in other disorders, includin, itself since left hemisphere dysfunction is often seen in, as dyslexia, delayed speech and stuttering, interference in the prenatal period describe, Considering all the abilities in the human reper, is interesting that savant skills generally narrow to five, often piano, with perfect pitch, although composing in, ability to compute prime numbers, for exampl, the absence of other simple arithmetic abilities, measure distances precisely without benefit of instr, ments, the ability to construct complex models, Other skills have been reported less often, prodigious language (poly-glot) facility; unusual, sensory discrimination in smell, touch or vision, including synaesthesia; perfect appreciation of.
