Two experiments were carried out using a same-different task with sets of four stimuli varying orthogonally in three dimensions. Sameness was defined by each of the three dimensions in turn, as well as by physical identity. Two types of dimensions, physical and cognitive, were studied. In Experiment 1, the numerals 6, 10, VI, and X, which vary in Length, System, and Name, were used. With simultaneous presentation, order of difficulty was from the physical dimension of Length to the cognitive dimension of Name. While overall difficulty was related to dimensional discriminability, internal evidence suggested that Name was not a dimension in the same sense as Length is, and that some stimulus pairs were simply easier to process than others, regardless of the response required (e.g., short stimulus pairs and Arabic numerals). With sequential presentation, Name was processed as fast as System, due largely to the fact that much faster responding occurred when an Arabic numeral was the second stimulus. Thus, with sequential presentation, Name provides a processing mechanism not provided by physical dimensions. In Experiment 2, the numerals 3, 4, 6, and 7, which vary in Magnitude, Oddness, and Curvilinearity, were used. The cognitive dimension of Magnitude was pro cessed most rapidly, and numerical distance between pairs of numbers dominated the results for “same” responses, regardless of the sameness rule used. Again, evidence was found for fast processing of some stimulus pairs (e.g., 3 4), regardless of the response required. Overall, these experiments are interpreted as indicating that cognitive factors such as stimulus familiarity may override aspects of physical discriminability with many dimensions and stimuli, that, even though a cognitive dimension can be used to generate a logically proper set of stimuli, it does not necessarily act as other, more physical dimensions do, and that clarification of the functional role of a dimension is more important than attempts to locate stages.  相似文献

The purpose of this article is to broaden our understanding of colic and to explore the effects of infant colic both on the mother's stress level and on her anxiety about separation from her infant. A “colic” group of 20 mother-infant dyads was compared with a second, control “noncolic” group of equal size. Significant group differences in the amount of time the infants cried, fussed, and were in a quiet/awake state were found. Although no difference in maternal trait anxiety was found, mothers in the colic group reported higher levels of stress associated with their infants' crying behavior. This stress was inversely related to the amount of time the infants slept during a 24-hour period. Mothers in the colic group also expressed significantly greater anxiety about separating from their infants for short periods of time; but the lack of freedom was significantly less of a problem for them than it was for mothers in the noncolic group. We conclude that mothers of difficult infants are more anxious about being separated from their infants, but do not appear to feel “trapped” by their extra maternal duties.  相似文献

Previous work has shown that bilingualism is associated with more effective controlled processing in children; the assumption is that the constant management of 2 competing languages enhances executive functions (E. Bialystok, 2001). The present research attempted to determine whether this bilingual advantage persists for adults and whether bilingualism attenuates the negative effects of aging on cognitive control in older adults. Three studies are reported that compared the performance of monolingual and bilingual middle-aged and older adults on the Simon task. Bilingualism was associated with smaller Simon effect costs for both age groups; bilingual participants also responded more rapidly to conditions that placed greater demands on working memory. In all cases the bilingual advantage was greater for older participants. It appears, therefore, that controlled processing is carried out more effectively by bilinguals and that bilingualism helps to offset age-related losses in certain executive processes.  相似文献

《黄帝阴符经》或《阴符经》是道教传统中一部极为主要的文本。虽然文本作者不详,而且篇幅短小、语义晦涩,但自唐代以来一直被当作奇书,引发多种注释与解读:内丹修炼抑或兵家谋略。本文以(唐)李荃注释本为主,阐述《阴符经》有关阴阳、生杀、机时、五贼、三盗等所涵盖的道家/道教的本体-宇宙观,并以此论述就有关暴力与战争议题所展示的道教伦理观。笔者认为,《阴符经》在重玄思辨中,强调道教"治身治国"的理念,其暗含的"义战"思想亦带有一定的黄老印记。  相似文献

The goal of this paper is to advance the measurement and theory of work–nonwork boundary management styles. Boundary management styles are defined as the approaches individuals use to demarcate boundaries and attend to work and family and other nonwork roles, given identity centralities and perceived boundary control. We argue that research should be augmented with a person-centered approach, which examines how psychological measures are integrated into configurations. Integrating role and boundary theories, we identify three main characteristics of work-nonwork boundary management: (1) cross-role interruption behaviors (work to nonwork, and nonwork to work interruptions); (2) identity centrality of work and family roles, and (3) perceived control of boundaries. Using a variable-centered approach, we refined and validated these measures to create an assessment (Work–Life Indicator) that captured boundary management profiles. The profiles reflect how interruption behaviors, identity centralities, and boundary control interrelate to cluster into profiles, a set of psychological characteristics organized into a pattern of work–nonwork boundary functioning. We identify boundary management profiles and examine their relationships to key work-family outcomes. Regardless of the level and direction of interruption behaviors and centrality of work–family identities, we found that low control boundary management profiles (reactors, job warriors) tended to experience more negative work and family outcomes than did high control profiles (fusion lovers, dividers, family guardians, eclectics).  相似文献

Underage drinking continues to be an important public health problem and a challenge to the substance abuse prevention field. Community-based interventions designed to more rigorously control underage access to alcohol through retailer education and greater enforcement of underage drinking laws have been advocated as potentially effective strategies to help address this problem, but studies designed to evaluate such interventions are sparse. To address this issue we conducted a randomized trial involving 36 communities to test the combined effectiveness of five interrelated intervention components designed to reduce underage access to alcohol. The intervention was found to be effective in reducing the likelihood that retail clerks would sell alcohol to underage-looking buyers, but did not reduce underage drinking or the perceived availability of alcohol among high school students. Post hoc analyses, however, revealed significant associations between the level of underage drinking law enforcement in the intervention communities and reductions in both 30-day use of alcohol and binge drinking. The findings highlight the difficulty in reducing youth drinking even when efforts to curtail retail access are successful. Study findings also suggest that high intensity implementation of underage drinking law enforcement can reduce underage drinking. Any such effects of enhanced enforcement on underage drinking appear to be more directly attributable to an increase in perceived likelihood of enforcement and the resultant perceived inconveniences and/or sanctions to potential drinkers, than to a reduction in access to alcohol per se.  相似文献

Many previous studies have linked religiosity to social trust. Yet much of this relation remains insufficiently understood, which is partly due to the fact that religiosity is a multidimensional phenomenon. In this article, we identify several of those dimensions, including the integration in religious communities, the importance of God in people's lives, and the religious context. These dimensions give rise to different mechanisms that produce both trust‐enhancing and trust‐reducing effects. Data from the European Values Survey (2008) were used to test the resulting hypotheses, using multilevel logistic regression models. We conclude that the micro effects are ambivalent: integration in religious communities furthers trust, whereas religious socialization and the importance of God lower trust. On the macro level, we find a strong effect of Protestantism, which is in line with previous studies, but that remains puzzling since the individual‐level difference between Protestants and the other religious traditions was found to be very small. In addition, in contrast to other studies, we found that religious diversity increases social trust.  相似文献

Risk Perception and Affect   总被引:4,自引:0,他引:4  
ABSTRACT— Humans perceive and act on risk in two fundamental ways. Risk as feelings refers to individuals' instinctive and intuitive reactions to danger. Risk as analysis brings logic, reason, and scientific deliberation to bear on risk management. Reliance on risk as feelings is described as "the affect heuristic." This article traces the development of this heuristic and discusses some of the important ways that it impacts how people perceive and evaluate risk.  相似文献

The importance of autonomy and choice to nursing home residents' well-being has been well established. This paper examines the complex role of regulation as it affects the autonomy of nursing home residents. Nonstandardized interviews with residents, family members, nursing staff members, and administrators were conducted at three nursing homes in suburban Maryland. These anecdotal interviews identified the most problematic areas where regulations enforce barriers to autonomy and control. These areas include: scheduling of activities of daily living, food portions, physical environment, and documentation. Suggestions for possible improvements are discussed.  相似文献

This study examined the development of aggressive and oppositional behavior among alcoholic and nonalcoholic families using latent growth modeling. The sample consisted of 226 families assessed at 18, 24, 36, and 48 months of child age. Results indicated that children in families with nonalcoholic parents had the lowest levels of aggressive behavior at all time points compared to children with one or more alcoholic parents. Children in families with two alcoholic parents did not exhibit normative decreases in aggressive behavior from 3 to 4 years of age compared to nonalcoholic families. However, this association was no longer significant once a cumulative family risk score was added to the model. Children in families with high cumulative risk scores, reflective of high parental depression, antisocial behavior, negative affect during play, difficult child temperament, marital conflict, fathers’ education, and hours spent in child care, had higher levels of aggression at 18 months than children in low risk families. These associations were moderated by child gender. Boys had higher levels of aggressive behavior at all ages than girls, regardless of group status. Cumulative risk was predictive of higher levels of initial aggressive behavior in both girls and boys. However, boys with two alcoholic parents had significantly less of a decline in aggression from 36 to 48 months compared to boys in the nonalcoholic group.  相似文献
