Visual problem solving in the absence of lexical semantics: Evidence from dementia

Psychiatric Manifestations of Pick’s Disease

“…Only terminally is there a global dementia (Cummings & Duchen, 1981;Holland et al, 1985;Sjiigren et al, 1952). Both clinical data and data from neuropsychological testing support the idea that visuo-spatial function remains relatively intact in PD (Gustafson & Hagberg, 1975;Hagberg & Gustafson, 1985;Holland et al, 1985;Johanson & Hagberg, 1981;Knopman et al, 1982;Marin et al, 1985). The ability of Mr. A in Case 1 to shoot paper-wad baskets is an excellent example of this.…”

“…Hypersexuality has been noted. Marin et al (1985) discussed the case of a woman who would approach strangers and kiss them passionately, telling them how much she loved them. This woman's behavior is an excellent example of the marked personality changes that occur, with intact cognitive functioning, early in this disease, as demonstrated by her continued abilities to work, balance a checkbook, care for her home, and drive a car.…”

The naming impairment of living and nonliving items in Alzheimer's disease

“…75013 -Paris, France. naming impairment has not been supported by most clinical and experimental observations (Marin et al, 1983;Schwartz, 1990) but an important interaction between perceptual and semantic processing has been emphasized (Humphreys & Riddoch, 1987;Chertkow & Bub, 1990;Humphreys etal., 1990;Chertkow etal., 1992aChertkow etal., , 1992b. The prevalence of errors within the semantic sphere, the production of errors within a semantic hierarchy, and an important comprehension impairment demonstrated in multiple recognition with semantic distractors suggest that the nature of the problem is more at the level of semantic representations rather than at the lexical (word retrieval) level (Schwartz et al, 1979;Martin & Fedio, 1983;Chanoine, 1992;Chertkow et al, 1992a;Cummings & Benson, 1992;Hodges et al, 1992).…”
