Recent studies have attempted to understand the processes involved in joint attention because of its relevance to both atypical and normal development. Data from a recent study of young children with autism suggests that performance on a delay nonmatch to sample (DNMS) task associated with ventromedial prefrontal functions, but not an A‐not‐B/delayed response task associated with dorsolateral prefrontal cortex, was related to joint attention skills (Dawson et al., 2002). Recent research also suggests that joint attention is associated with dorsalmedial brain systems linked to self‐monitoring (Mundy, 2003). This study investigated the relations among joint attention, DNMS, and self‐recognition performance in a longitudinal study of 39 normally developing toddlers from 14 to 18 months. The results indicated that development on the DNMS and self‐recognition tasks, but not a means end task, predicted joint attention at 18 months. Further analysis showed that the model was only significant for initiating joint attention (IJA). The implications of these results for the neuro‐development of IJA are discussed.  相似文献

Antihomosexual prejudice, popularly referred to as homophobia, is a complex phenomenon whose roots traditionally have been traced to the cultural context. However, such theoretical explanations fall short of accounting for the power and endurance of this bias. By locating the threat of homophobia in the development of male core gender identity and female heterosexual object choice, the author suggests that heterosexual men's and women's responses to homosexuality may have different origins. She further argues that only by combining cultural with psychodynamic factors may the clinician develop a sufficiently empathic response to patients struggling with homophobic affects.  相似文献

Subjects imagined situations in which they reported enjoying themselves either alone or with others. Electromyographic (EMG) activity was recorded bilaterally from regions overlying thezygomatic major muscles responsible for smiling. Controlling for equal rated happiness in the two conditions, subjects showed more smiling in high-sociality than low-sociality imagery. In confirming imaginary audience effects during imagery, these data corroborate hypotheses that solitary facial displays are mediated by the presence of imaginary interactants, and suggest caution in employing them as measures of felt emotion.Avery Gilbert and Amy Jaffey had compelling insights throughout the course of study.

This study was designed to determine the extent of sandwiched families and the impact of dependency and proximity to task assistance provided to parent(s). Data were collected in Idaho, Oregon, Utah, and Michigan from a random sample of 40–65-year-old respondents. Fifteen percent are sandwiched between needs of aging parents and financially dependent children. Respondents are much more likely to be providing assistance to mothers than fathers. Parents are most likely to live near, but not necessarily with, the respondent. Spouses and partners' parents, however, are likely to live farther away. Task assistance provided most often to aging parent(s) includes help with transportation and shopping; financial assistance was reported least often. Income of respondent and dependency and proximity of parents are significantly related to providing assistance to parents. This study offers a unique glimpse at the relationships between personal characteristics, dependency, proximity, and task assistance issues as they pertain to the sandwich generation.  相似文献

The theory of higher-order asymptotics provides accurate approximations to posterior distributions for a scalar parameter of interest, and to the corresponding tail area, for practical use in Bayesian analysis. The aim of this article is to extend these approximations to pseudo-posterior distributions, e.g., posterior distributions based on a pseudo-likelihood function and a suitable prior, which are proved to be particularly useful when the full likelihood is analytically or computationally infeasible. In particular, from a theoretical point of view, we derive the Laplace approximation for a pseudo-posterior distribution, and for the corresponding tail area, for a scalar parameter of interest, also in the presence of nuisance parameters. From a computational point of view, starting from these higher-order approximations, we discuss the higher-order tail area (HOTA) algorithm useful to approximate marginal posterior distributions, and related quantities. Compared to standard Markov chain Monte Carlo methods, the main advantage of the HOTA algorithm is that it gives independent samples at a negligible computational cost. The relevant computations are illustrated by two examples.  相似文献

Although sociologists have long been interested in the stratification of emotions, the occupational stratification of anger has been investigated in only a few general population studies. Through analyses of data representative of workers in Toronto, we evaluate the hypothesis that workplace hierarchical position, defined by supervisory level, has an inverted u‐shaped association with the frequency of anger about work. We also evaluate the more specific hypothesis that the difference in work‐related anger between front‐line supervisors and nonsupervisory workers will be relatively larger among workers in the commodified services sector than other sectors. Results are generally consistent with our hypotheses. We find that both front‐line supervisors in the commodified services sector, and secondary supervisors in all employment sectors, report more frequent anger about work than do nonsupervisory workers. In contrast, higher level supervisors report anger about work at about the same frequency as nonsupervisory workers. These associations are only slightly reduced by controls for work stress and stressors. We discuss how supervisory relations might explain differences in anger about work among workers at different levels in organizational hierarchies.  相似文献

Urban-associated changes can have immediate or long-term consequences on animal populations. Such changes may be assessed through parasite prevalence and abundance in wildlife hosts, as urbanization can influence parasitism and disease transmission in wildlife. Snakes are widespread and diverse vertebrates that often persist in urban environments; however, parasitism of snakes in urban environments has yet to be studied, leaving the roles of snakes in parasite transmission uncharacterized. Field ecology, microscopy, molecular techniques, and geographic information science (GIS) were integrated to characterize parasitism of snakes in an urban old-growth forest park. The species, sex, mass, length, location, and prevalence of ecto-, hemo-, and fecal parasites were determined for 34 snakes of 6 species. Ectoparasites (mite), hemoparasites (Hepatozoon spp.), and fecal parasites (Entamoeba spp., Trichomonas spp., Strongloides spp., and an unidentified helminth) were detected in snakes and 64.7?% of snakes were infected by at least one of these parasites. Parasite infections were generally not related to the sex, age, or body condition of snakes. The locations of infected snakes were used to produce risk maps indicating where parasite prevalence is predicted to be greatest. The analysis of these maps indicated that snakes with fecal parasites were closer than non-infected snakes to the edge of the forest. This study confirms that snakes may be important parasite hosts or reservoirs in parasite transmission pathways in urban environments and it provides an integrative multidisciplinary approach that may be used to monitor parasitism dynamics in other urban wildlife areas.  相似文献

Drawing on Canadian police data on homicide involving domestic dispute calls from 1960 to the present (n = 20), as well as on in‐depth interviews with police officers (n = 33) working in rural and remote communities, the authors reexamine the argument that police attendance at domestic disturbance calls can pose a special threat to officer safety. Although some scholarship suggests that purported risks have been overstated, the authors argue that location may be a critical factor in reducing or heightening not only risks to officers, but also to victims. Although intended as an exploratory work, situated within the context of cultural support for domestic violence in rural communities, the authors raise both interesting policy implications, as well as potential avenues for future research. En partant de données de la police canadienne sur les homicides impliquant des disputes familiales de 1960 à nos jours (n = 20), ainsi que sur des entrevues en profondeur avec des agents policiers (n = 33) travaillant dans des régions rurales et des communautés éloignées, les auteurs ré‐examinent l'argument voulant que les interventions policières lors d'appels liés à des problèmes domestiques posent un risque spécial pour les agents policiers. Même si certains spécialistes suggèrent que ces risques sont exagérés, les auteurs affirment que le lieu pourrait être un facteur important par rapport au niveau de risque pour les agents policiers, ainsi que les victimes. Même s'il s'agit d'une recherche exploratoire, se situant dans le contexte du soutient culturel de la violence domestique dans les communautés rurales, les auteurs s'intéressent à la fois aux implications en termes de gestion et aux directions possibles en termes de recherches futures.  相似文献

This study uses content analysis to provide a qualitative exploration of how life roles are affected by frequent (i.e. at least weekly) gambling, based on in-depth interviews with a community sample of 161 non-treatment-seeking frequent gamblers. Over half (51.6%) of the participants indicated problems associated with gambling and 131 examples were identified. The majority of problems were relational (50.4%), followed by financial (19.8%), work (13.7%), and school related (8.4%). Slightly less than half of participants (41.7%) reported losses due to gambling and 92 examples were provided. The most frequently reported loss was identity related (54.3%), which included self-esteem/shame (38.0%), estrangement from family (34.0%), estrangement from friends (16.0%), and estrangement from work colleagues (6.0%). Additional losses included health (29.3%) and financial (8.7%). Almost two-thirds of participants (64.6%) reported difficulty concentrating in family (18.4%), work (16.8%), and school (9.6%) activities, whereas general concentration problems comprised an additional 48.8% of the examples provided. Half of participants (49.1%) discussed behavioral withdrawal due to gambling, which included withdrawal from work (44.3%), relationships (24.5%), school (15.1%), and personal (6.6%) activities. These findings paint a complex picture of how gambling interferes with different life roles for some frequent gamblers, identifying important areas for future research and practice.  相似文献
