Craik (1986) has proposed that age-related deficits on memory tasks are proportional to the extent to which these tasks require the use of self-initiated operations. Because the number of required self-initiated operations vary among traditional episodic memory tasks, these tasks should display a gradation of age-related deficits. The objective of this study was to test this hypothesis. A secondary analysis (i.e. based on the results of previous studies) was performed on 22 studies in which verbal stimuli were used as targets on more than one episodic memory task. Of the 24 comparisons provided by the studies, 21 supported the gradation concept. This result suggests that the self-initiated operation hypothesis is valid.

Until now, family caregivers have been involved very little in the processes of assessing the quality of care delivered to a hospitalized relative. This study is the second phase of a broader research project whose aim is to develop measurement scales intended for elderly patients and their caregivers on their perceptions of the quality of services delivered in Geriatric Assessment Units. More specifically, the goal of this phase of the research is to document the criteria that caregivers use to judge the quality of these services: these criteria should constitute the content of the measurement scale that is intended for them. Four focus groups, bringing together 21 caregivers, allowed for the identification of 31 criteria of quality. These criteria have been classified according to six dimensions of quality: information, communication, attitude of staff, technical quality, continuity, and physical resources. The study highlights the dual concerns of participants: the well-being of the patient and support for caregivers. It shows that caregivers consider themselves to be clients of geriatric services.

The assessments of research in social gerontology in Quebec are already numerous. The need to continue to reflect on one's work is a sign of the uncertainty amongst Quebec researchers in social gerontology. Although research activities have been multiple in the past years and research in social gerontology has a few of the characteristics of an institutionalized scientific activity, the experience of research centres in gerontology has not always been a happy one; researchers have no definite place of work and scientific publications hardly get out of Quebec. Nevertheless, numerous works should be entitled to a Canadian and international circulation, and this exposure to the international trends of research in social gerontology would in turn profit Quebec researchers. Moreover, research in social gerontology is too exclusively concentrated in the field of social psychology, while the almost ideological rejection of quantitative methods appears largely unjustified. It is imperative that social research in gerontology in Quebec be diversified, but it is also important that researchers group together around research themes and that these groups be given adequate financial assistance by the funding agencies.

Explanatory frameworks in social gerontology often appear to represent variations on a theme. Regardless of subtype, linearity, ordinality, and universality are customarily assumed. This discussion advocates for an alternative model, an exploration of the utility of a new, transformative logic associated with chaos theory and related perspectives. As a metaphor, chaos theory can help gerontologists address contextualized change and non-linear dimensions of human aging processes.

In an age of globalization and privatization, local governments and municipalities are searching to define their social role and place. In an aging society such as Canada, arguing that promoting the legal rights of older persons should be part of the legal authority of the municipal government is not simple. It is easier to abide by the position that, without an efficient centralized machinery, social and environmental problems will remain unsolved or unaddressed.

This article presents a different understanding of the place of municipal government in Canada. The goal of this article is to present an original legal-policy argument: It is time for local communities and local governments in Canada to use their legal authorities to enact local bylaws that define and establish the rights of their older citizens. The argument maintains that local municipalities hold the legal power and the social potential to make a significant contribution in the legal sphere for promotion of the rights of older people, and that this power has been neglected.

The article supports the argument on three pillars: (1) an empirical analysis of bylaws in different municipalities across Canada; (2) a socio-legal analysis of the advantages of municipal law as a tool for social change; (3) a case analysis of a recent municipal legal reform in British Columbia.

The results of examining all hospitalizations of the elderly consequent to injury in one Canadian province indicate that 66.3% were for accidental falls and 21.3% were for “other accidents” and for adverse effects of therapeutic regimens. Nursing home residents were significantly more likely to be hospitalized for falls than community dwellers but very elderly institutionalized females, who comprise 40% of the nursing home population, used significantly fewer days than their community peers.

We analysed a prospective cohort study to determine (1) if self-rated health (SRH) predicts mortality in older adults with and without depressive symptoms, and (2) to determine if there is an interaction between SRH and depressive symptoms on mortality. We followed 1,751 community-dwelling adults aged 65 and older over five years. Measurements included age, gender, education, the Center for Epidemiological Studies-Depression (CES-D), SRH, the Modified Mini-Mental State Examination (3MS), and the Older Americans Resource Survey (OARS). Our outcome measure was time to death. Analyses were conducted in those with, and those without, depressive symptoms. We constructed Cox regression models with an interaction term for the CES-D and SRH. The hazard ratio (HR) for mortality was 1.63 for those with depressive symptoms; it was 1.68 for those without. No significant interaction was found between depressive symptoms and SRH for mortality.

In the Person-Environment (P-E) Congruence model, psychological well-being is proposed to be a function of the degree of fit between the perceived environment and the important needs of the individual; and, that in more restricted environments, the relationship is stronger. The present study examined, cross-sectionally and longitudinally, the Congruence levels and well-being of elderly veterans (N = 165) in four microenvironments within a single instutition. Congruence was assessed using the multidimensional Environmental Perception, Preference and Importance Scale (EPPIS). Well-being was measured using the PGC Moral Scale, the Life Satisfaction Index A and a semantic differential self-concept scale. There were significant microenvironment differences on three of the 15 EPPIS dimensions; the P-E Congruence scores were predictive of well-being; and, the specific dimensions predictive of well-being varied across microenvironments, criterion of well-being and time. The data reinforces the notion that treatment programs must be individualized and that the P-E model, operationalized in the EPPIS, may serve as a viable clinical tool.

Secondary analysis of data from the Health and Activity Limitations Survey (HALS) in the metropolitan Montreal area shows that 3.5 out of 10 elderly persons living in a household had a disability. In this descriptive research, we locate the dependency level according to the attributes of the elderly and of their residence. Approximately three out of four elderly with a disability receive help and one out of three are assessed as needing more help. Assistance varies with the person who helps. The family mostly helps for everyday activities, friends for shopping, and private or governmental services for personal care and household tasks. Assistance varies also with the marital status of the elderly person. Finally, the presence of special devices is associated with type of housing.

The level of liver polyploidy was compared in three groups of humans: a young group aged 20–46, an older group aged 62–68 and the oldest group aged 70–79. The most important trend showed by the data was that there is a depletion of 2N and 4N cells, accompanied by an increase in 8N and 16N cells as a function of advancing age. There was a high degree of variability in the percentage of cells in each ploidy class from one individual to the next for all age groups. For this reason, polyploidy appears to be a less effective biomarker of aging in humans than it is in experimental animals.

Age differences in verbal and spatial learning and information processing were tested using a verbal word list learning task and a spatial analogue of this task. Recall was assessed across five learning trials and the same measures of information processing and organization strategy were derived from both tasks. Normal subjects divided into three age groups of 24 subjects each were compared on these instruments. Significant age group differences were found for total recall averaged across trials and type of task (verbal vs. spatial). Age was not differentially related to verbal versus spatial learning and age groups did not show different patterns of recall across trials. Age was related to a clustering measure which assessed organization of information according to verbal semantic categories or inherent spatial clusters. Younger subjects showed increased levels of clustering on earlier learning trials. Similar effects were observed for the verbal and spatial clustering measures. Age was not related to differences in organization according to temporal order of presentation of information. Results show similar age-related changes in verbal and spatial learning and provide evidence that spatial learning, like verbal learning, is dependent upon effortful information processing.

The performance of seven Parkinson patients on a discrete pursuit tracking task was studied under alleviated (medicated) and unalleviated (non-medicated) conditions, and compared with the performance of seven non-Parkinson subjects matched for age and gender. All subjects completed 2,000 responses on the tracking task, which provided variations in directional probability and the distance to be moved. Overall, results suggested that once given sufficient practice to learn a novel task, and when under drug control, Parkinson patients were not significantly different from their age-matched controls. Two exceptions where Parkinson patients evidenced slower responses were noted: (a) their ability to make decisions when movement direction was less predictable: and (b) when they had to readjust their motor responses after an unexpected movement error.

The transport and metabolism of glucose was compared in cultured skin fibroblasts derived from normal and Alzheimer disease affected individuals. No significant differences were observed in sugar transport, CO2 production, lactate production, trichloroacetic acid soluble and precipitable material between the test groups. It is concluded that altered glucose uptake or metabolism is not a general characteristic of all Alzheimer disease cultured fibroblasts.
