Recently, the media have expressed concern about the apparent concentration and social isolation of immigrants in central and inner suburban neighborhoods in large Canadian cities. This paper compares and contrasts the frequency and nature of neighborhood-based social contacts among three cohorts of immigrants distinguished by their period of arrival in Canada and Canadian-born individuals. We begin by outlining the family, friend, and acquaintance relationships that immigrants build and argue that their networks are culturally diverse and dominated by acquaintances. In this context, intense friendships rarely develop between neighbors, even for recent newcomers. Rather, neighboring consists mainly of casual interactions between individuals that often involve the provision of mundane forms of assistance. Despite their fleeting and routine qualities, social relations with neighbors lead the vast majority of people to express strong levels of belonging to their neighborhoods. As a consequence, we argue that the neighborhood is an underestimated locale for understanding social inclusion. 相似文献

Prior research examining maintenance in cross-sex friendships focuses heavily on platonic (i.e., nonsexually active) friendships with limited research examining sexually involved cross-sex friendships (i.e., “friends with benefits relationships”). In this study, we investigated differences in relational maintenance behaviors between sexually and nonsexually active cross-sex friendships types. In an online survey, 531 emerging adult participants from large southwestern and southeastern universities identified either a friends with benefits or platonic opposite sex friendship and then completed items asking them to report the frequency with which they enacted each of 36 relationship maintenance behaviors. Overall, participants involved in casual sex friendships engaged in the least, and those who transitioned from a friends-with-benefits relationship to a romantic relationship engaged in the most frequent relationship maintenance. Platonic friendships employed more frequent maintenance than casual-sex friendships but less than either true friends with benefits or participants who transitioned to a romantic relationship. 相似文献

Social behaviors, such as joint attention, social referencing, and protocommunicative acts, which emerge toward the end of the first year of life, have commonly been taken as evidence of considerable social understanding, even an "implicit" theory of mind. We identify the theoretical assumptions that this "commonsense view" entails and argue against this view of these behaviors by suggesting that the phenomena are entirely compatible with an account which does not attribute to the infant an understanding that others have psychological relations to objects or that self and others are equivalent in their potential for such psychological relations. We end by arguing that the account we propose potentially provides a developmental solution to the problem of how the child develops a theory of mind that is equally applicable to self and other without postulating the existence of considerable innate knowledge. 相似文献

Mental calculation is an important everyday skill involving access to well-learned procedures, problem solving, and working memory. Although there is an active literature on acquiring concepts and procedures for mental arithmetic, relatively little is known about the role of working memory in this task. This paper reports two experiments in which dual-task methodology is used to study the role of components of working memory in mental addition. In Experiment 1, mental addition of auditorily presented two-digit numbers was significantly disrupted by concurrent random letter generation and, to a lesser extent, by concurrent articulatory suppression, but was unimpaired by concurrent hand movement or by presentation of irrelevant pictures. Although the number of errors increased with two of the dual tasks, the incorrect responses tended to be quite close to the correct answer. In Experiment 2, the numbers for addition were presented visually. Here again, random generation produced the largest disruption of mental arithmetic performance, while a smaller amount of disruption was observed for articulatory suppression, hand movement, and unattended auditorily presented two-digit numbers. The overall levels of performance were better and the absolute size of the disruptive effects shown with visual presentation was very small compared with those found for auditory presentation. This pattern of results is consistent with a role for a central executive component of working memory in performing the calculations required for mental addition and in producing approximately correct answers. Visuospatial resources in working memory may also be involved in approximations. The data support the view that the subvocal rehearsal component of working memory provides a means of maintaining accuracy in mental arithmetic, and this matches a similar conclusion derived from previous work on counting. The general implications for the role of working memory in arithmetic problem solving will be discussed. 相似文献

After discussing the nature of corporate symbols and the factors involved in understanding them, this paper reports two studies. We test various conjectures about the process of comprehension using a single, complex corporate symbol. Three sources of information are shown to contribute to an individual's understanding of the symbol: (1) the purpose ofthe communication; (2) the properties of the symbol–graphical and referential; and (3) the context in which the symbol is seen. We also show that the process is constrained in predictable ways. We consider these studies to be a step in the development of a psychological theory to inform the process of designing symbols. 相似文献

Four studies used an attributional approach to examine interpersonal attraction. Underlying causal dimensions were predicted to influence differentially two components of attraction, dating and complimenting. In the first study, 24 subjects indicated whether they would date physically attractive stimulus persons. Complimenting was examined in the second and third studies, with 24 subjects rating the likelihood of complimenting attractive opposite-sex stimulus persons and 32 subjects rating the likelihood of complimenting same-sex stimulus persons. For these studies the reason for the stimulus person's attractiveness varied in controllability (volitional versus nonvolitional) and stability (temporary versus permanent). Consistent with predictions, controllability influenced likelihood of complimenting but not dating. In addition, compliments were more likely when the reason for attractiveness was unstable than when stable. Conversely, dating was more likely when attactiveness was stable than when unstable. However, stability had less influence on men responding to women than on either men responding to men or women responding to both sexes. Similar results were obtained in a fourth study in which 56 subjects recalled incidents where they complimented or dated others for their physical attractiveness. 相似文献

Body-weight maintenance is required in a variety of behavioral and physiological studies. A PC-based animal-weighing system is described; it features automated data collection and allows for accurate control of body weight in test animals via manipulation of food intake. Major system components are a PC XT-compatible computer, Lotus 1-2-3 and National Instruments Measure software, and a digital electronic balance. The system is controlled by Lotus macros, which present menus to the user. Menus provide for the basic operations of the system, including establishing new data files, collecting weight data, printing, and transferring files to a laboratory minicomputer. The optional weight-maintenance algorithm calculates the amount of food necessary to maintain target body weights. Some important aspects of this algorithm, including maintenance-feeding and gain parameters, can be manipulated to reduce weight oscillation in test animals or to accommodate the maintenance of body weight of different animal species. The system facilitates acquisition and recording of weight data, minimizes the frequency of error, and reduces variability both within and across animals when body-weight maintenance is required. 相似文献
