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

The Sandwich Generation: Dependency, Proximity, and Task Assistance Needs of Parents 总被引:2,自引:1,他引:1
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

Deterrence in the workplace: perceived certainty, perceived severity, and employee theft 总被引:5,自引:0,他引:5
Hollinger RC Clark JP 《Social forces; a scientific medium of social study and interpretation》1983,62(2):398-418
The phenomenon of employee theft is examined empirically, utilizing a deterrence paradigm. Employees selected randomly from three different industry sectors and metropolitan areas were asked to self-report their involvement in a number of property theft activities within the employment setting. Using a weighted least-squares logit regression analysis, the study found that the perception of both the certainty and severity of organizational sanctions were related to employee theft. Males reported more theft than did females, but contrary to previous research, no gender/certainty or gender/severity interactions were observed. The best-fit model did, however, contain two significant first-order interactions: age/certainty and age/severity. These interactions strongly suggest that younger employees are not as deterrable as their older peers, especially under conditions of both high certainty and high severity of punishment. While a number of possible explanations might account for differential deterrability according to age, a commitment to or stakes in conformity explanation is proposed. 相似文献

The question which, unfortunately, often goes unanswered, is whether a company's process of corporate planning is optimal. Furthermore, even if they wished to answer such a question there is little in the literature which can provide them with a direct, and explicit evaluative model. This paper examines the development of planning and the many different contributors towards its theoretical underpinning. Whilst recognizing that planning is a field which is a ‘semantic's jungle’ the authors carefully pick their way through the mine-field of misunderstanding and misquotation and clearly establish a base-line for evaluation and indeed propose a detailed methodology. It is hoped that this paper will be a fore-runner of many which will assist the executive in his important evaluative role concerning alternative planning approaches. 相似文献

Near-miss outcomes during gambling are non-win outcomes that fall close to a pay-out. While objectively equivalent to an outright
miss, near-misses motivate ongoing play and may therefore be implicated in the development of disordered gambling. Given naturalistic
data showing increases in heart rate (HR) and electrodermal activity (EDA) during periods of real gambling play, we sought
to explore the phasic impact of win, near-miss and full-miss outcomes on physiological arousal in a controlled laboratory
environment. EDA and HR were monitored as healthy, student participants (n = 33) played a simulated slot-machine task involving
unpredictable monetary wins. A second gambling distortion, perceived personal control, was manipulated within the same task
by allowing the participant to select the play icon on some trials, and having the computer automatically select the play
icon on other trials. Near-misses were rated as less pleasant than full-misses. However, on trials that involved personal
choice, near-misses produced higher ratings of ‘continue to play’ than full-misses. Winning outcomes were associated with
phasic EDA responses that did not vary with personal choice. Compared to full-misses, near-miss outcomes also elicited an
EDA increase, which was greater on personal choice trials. Near-misses were also associated with greater HR acceleration than
other outcomes. Near-miss outcomes are capable of eliciting phasic changes in physiological arousal consistent with a state
of subjective excitement, despite their objective non-win status. 相似文献

The purpose of this article is to briefly describe the application and funding process at the National Institutes of Health (NIH). We target our discussion to demographic and population science at the Eunice Kennedy Shriver National Institute of Child Health & Human Development (NICHD), but the general strategies are applicable to social and behavioral scientists for all NIH funding opportunities. 相似文献
