Environmental contaminants can alter the course of neural development, with consequences that appear in behavior. Such effects extend into adulthood and sometimes accelerate the rate of aging, even when exposure ceases by birth. The neurotoxicant methylmercury provides an interesting case study that reveals much about how disrupted neural development has lifelong consequences. Methylmercury also provides an example of the assessment and management of risks associated with exposure to developmental neurotoxicants. 相似文献

Since the first offender rehabilitation treatments, all theoretical approaches have been focusing on reducing risk factors that may influence recidivism, without satisfactory results. Recent resilience research has instead shown the important mediating or moderating role of protective factors and provided the theoretical principles for the Good Lives Model Comprehensive. This holistic model suggests the importance of integrating the reduction of risk factors with the reinforcement of protective factors in offenders' treatment programs. This combined action is considered the main condition through which offenders are motivated to change their life and develop a sense of agency on their current life conditions. This article presents a pilot study, aimed at analyzing the feasibility of a psychosocial intervention, based on graphic workshops. The purpose of the intervention is helping prisoners strive toward adaptation in jail, and facilitating the redesign of their life beyond bars. Drawing activities allowed prisoners to enhance their own internal and external resources, and recognize risk and protective factors that could influence their successful reintegration into society. The main limit of this study is directly linked to the setting of the penitentiary institution where the study was conducted, which is characterized by a high prisoners' turn over. 相似文献

The aim of the study was to determine whether the memory capacity of individuals with age-associated memory impairment (AAMI) over a period of approximately 3½ years declines more, if at all, than the memory capacity of persons without AAMI. Four computerized and three non-computerized memory tests, a naming test, and a test of visuo-motor speed were administered twice. Two estimates of intellectual capacity were made, one at the first examination and the other 3½ years later. One person in the AAMI group (n=44) developed vascular dementia. The group of AAMI subjects did less well on two of the seven memory tests after 3½ years than they did initially; the control group (n=18) had lower scores on one memory test at follow-up than they had previously. The data suggest that the memory capacity of subjects with AAMI is not pathologically impaired. The general intellectual level significantly influences whether an individual with memory complaints will be classified AAMI or not. People with high intelligence are less likely than people with lower intellectual capacity to fulfill the AAMI criteria. This suggests that AAMI lacks in construct validity. 相似文献

Individual differences in spatial memory among young and aged rats were assessed using memory tasks related to integrity of the hippocampus and the neostriatum. Relationships were then examined between measures of spatial memory and regional choline acetyltransferase (ChAT) activity, a marker for cholinergic integrity. Twenty-four-month-old Long-Evans rats were impaired in comparisons with 6-month-old rats on measures of place learning, working memory, reference memory, and perseveration in water-maze tasks. Aged rats that were impaired on one measure of memory, however, were not necessarily impaired on other measures. ChAT activity in the ventromedial and dorsolateral neostriatum of aged rats was significantly reduced in comparisons with young rats whereas no difference was found in the hippocampus. Aged rats with the most ChAT activity in the anterior ventromedial neostriatum performed best on the place-learning and reference memory tasks but also made the most perseverative errors on the working memory task. In addition, young and aged rats with the most ChAT activity in the anterior dorsolateral neostriatum were those with the least accurate working memory. No relationships were found between ChAT activity in the hippocampus and spatial memory. Thus age-related memory impairment has components that can be segregated by measuring relationships between cholinergic integrity in subregions of the anterior neostriatum and memory tasks with different strategic requirements. 相似文献

Robert Kastenbaum has argued that we need to take a life-span approach to the lives of artists in order to determine what factors affected their creativity. To that end, I briefly review the lives of four writers, Jane Austen, E. M. Forster, Barbara Pym, and Henry Roth. Each followed a different pattern: Austen wrote productively until her early death; Forster ceased to write novels after his midlife success; Barbara Pym continued to write until her death from cancer; and Henry Roth restarted his moribund career in his seventies. These differences suggest that creativity is closely connected to life events and the artist's psychological state of mind. 相似文献

Creativity and Aging: Personal Journals and the Creation of Self 总被引:1,自引:0,他引:1
Harry J. Berman 《Journal of Aging and Identity》1998,3(1):3-9
This article considers the writing of personal journals as a process through which an individual constructs a linguistic representation of one's self, with the self constituting a narrative. Rather than a fixed narrative, one's life exists as a narrative subject to revision and reinterpretation. Through journal writing, then, one constructs and reconstructs his or her identity. Berman finds the value in personal journals not only in the themes that surface but also in the creative process they reveal. In this article, he examines passages from five journalists that demonstrate this process of creating and revising meaning in one's life. 相似文献

Libertarianism vs. Marxism: Reflections on G. A. Cohen‘s Self-Ownership, Freedom and Equality 总被引:1,自引:0,他引:1
Jan Narveson 《The Journal of Ethics》1998,2(1):1-26
Self-Ownership, Freedom and Equality is G.A. Cohens attempt to rescue something of the socialist outlook on society from the challenge of libertarianism, which Cohen identifies with the work of Robert Nozick in his famous book, Anarchy, State, and Utopia. Sympathizing with the leading idea that a person must belong to himself, and thus be unavailable for forced redistribution of his efforts, Cohen is at pains to reconcile the two. This cannot be done – they are flatly contrary. Moreover, equality is a nonsense principle, calling for such things as equal distribution of natural resources. But resources, as goods, are not natural: all require work to utilize. The only thing exchanged on markets is services, and estimates of value received are relevantly made only by those party to the exchanges in question. Imposition from above on voluntary exchange can only be socially counterproductive. 相似文献

Event-Related Potentials (ERPs) were collected concurrently with stimulus presentation during a source monitoring task. Younger adults were less likely than older adults to make source monitoring errors and their ERP records showed far greater discrimination between target stimuli and familiar but nontarget foils. Older adults not only made more source errors but produced high amplitude late positivities to the nontarget foils even when these foils were correctly rejected. Under divided attention conditions, younger adults performance was similar to that of the older adults both behaviorally and electrophysiologically. These data illustrate the role that attentional resources play in the ability to inhibit response tendencies and suggest that age differences in source monitoring may be more related to attentional control than inefficiencies in the encoding of contextual information. As well, they suggest that the ERP late positivity may represent a more general response to item salience rather than serve as an index of recollection as is the current view. 相似文献

We propose the savanna theory of happiness, which suggests that it is not only the current consequences of a given situation but also its ancestral consequences that affect individuals’ life satisfaction and explains why such influences of ancestral consequences might interact with intelligence. We choose two varied factors that characterize basic differences between ancestral and modern life – population density and frequency of socialization with friends – as empirical test cases. As predicted by the theory, population density is negatively, and frequency of socialization with friends is positively, associated with life satisfaction. More importantly, the main associations of life satisfaction with population density and socialization with friends significantly interact with intelligence, and, in the latter case, the main association is reversed among the extremely intelligent. More intelligent individuals experience lower life satisfaction with more frequent socialization with friends. This study highlights the utility of incorporating evolutionary perspectives in the study of subjective well‐being. 相似文献
