Semantic knowledge was investigated in patients diagnosed with Dementia of the Alzheimer's Type (DAT) by means of an off-line probe question battery and an on-line measurement of semantic priming in a lexical decision task (LDT) that varied the stimulus onset asynchrony (SOA). The patients' performance on the detailed probe questions showed that their semantic deficit was confined primarily to animate concepts, characterized by visual descriptive features. In the primed LDT, demented patients demonstrated increased semantic priming compared to age-matched controls. A trend was also found indicating that for both normal controls and DAT subjects the priming magnitude decreased as the SOA increased. These results are interpreted in terms of a distributed representation of semantic knowledge that is impaired in demented patients.

A rapidly growing senior population is facing loneliness, desolation andisolation in our ageist society. Age-linked detachment and a number of socialinteractors are closely related to general health, physical condition anddepression.Using standardized instruments, the UCLA Loneliness Scale (Russellet al., 1980), the Multidimensional Scale of Perceived Social Support (Zimetet al., 1988), and the Geriatric Depression Scale (Brink et al., 1982), this nonexperimental-study investigated the level of perceived loneliness, socialsupport and the causative relationship of these factors to the presence ofdepression among 50 independent, relatively healthy elders in a Montrealsenior centre.Findings suggest that loneliness is a major predictor of elderdepression. Lack of perceived social support could contribute to sensedloneliness and that depression may be present in healthy, independentelderly.Intergenerational workshops for seniors are suggested to improve lifesatisfaction through social interaction. Further goals are to modify myths,stereotypes and contradictory attitudes inherent to the cohort. / fr
