Nurses working for telephone‐based medical helplines must maintain attentional focus while quickly and accurately processing information given by callers to make safe and appropriate treatment decisions. In this study, both higher levels of general occupational stress and elevated stress levels on particular shifts were associated with more frequent failures of attention, memory, and concentration in telephone nurses. Exposure to a stressful shift was also associated with a measurable increase in objectively assessed information‐processing errors. Nurses who experienced more frequent cognitive failures at work made more conservative decisions, tending to refer patients on to other health professionals more often than other nurses. As stress is associated with cognitive performance decrements in telephone nursing, stress‐reduction interventions could improve the quality and safety of care that callers to medical helplines receive.  相似文献

Popular stereotypes suggest that generational differences among workers present challenges for workplace managers. However, existing empirical research provides mixed evidence for generational differences in important values and attitudes. The current study extends generational effects research by examining differences in actual workplace behaviors. Drawing from commonly held generational stereotypes, the authors hypothesized that Baby Boomers would exhibit (Hypothesis 1) fewer job mobility behaviors and (Hypothesis 2) more instances of compliance‐related behaviors in comparison with both GenXers and Millennials, while (Hypothesis 3) GenXers would be less likely to work overtime in comparison with Baby Boomers and Millennials. A sample of 8,040 applicants at two organizations was used to test these predictions. Results provided support for Hypothesis 1 and Hypothesis 3 and partial support for Hypothesis 2, but the effect sizes for these relationships were small. It appears the effects of generational membership on workplace behavior are not as strong as suggested by commonly held stereotypes. Implications for future research and practice are discussed.  相似文献

A fast growing field, the study of infants at risk because of having an older sibling with autism (i.e. infant sibs) aims to identify the earliest signs of this disorder, which would allow for earlier diagnosis and intervention. More importantly, we argue, these studies offer the opportunity to validate existing neuro-developmental models of autism against experimental evidence. Although autism is mainly seen as a disorder of social interaction and communication, emerging early markers do not exclusively reflect impairments of the “social brain”. Evidence for atypical development of sensory and attentional systems highlight the need to move away from localized deficits to models suggesting brain-wide involvement in autism pathology. We discuss the implications infant sibs findings have for future work into the biology of autism and the development of interventions.  相似文献

Two important and related developments in children between 18 and 24 months of age are the rapid expansion of object name vocabularies and the emergence of an ability to recognize objects from sparse representations of their geometric shapes. In the same period, children also begin to show a preference for planar views (i.e., views of objects held perpendicular to the line of sight) of objects they manually explore. Are children's emerging view preferences somehow related to contemporary changes in object name vocabulary and object perception? Children aged 18 to 24 months old explored richly detailed toy objects while wearing a head camera that recorded their object views. Both children's vocabulary size and their success in recognizing sparse three-dimensional representations of the geometric shapes of objects were significantly related to their spontaneous choice of planar views of those objects during exploration. The results suggest important interdependencies among developmental changes in perception, action, word learning, and categorization in very young children.  相似文献

Abstract

The thesis that meaning is normative has come under much scrutiny of late. However, there are aspects of the view that have received comparatively little critical attention which centre on meaning’s capacity to guide and justify linguistic action. Call such a view ‘justification normativity’ (JN). I outline Zalabardo’s (1997) account of JN and his corresponding argument against reductive-naturalistic meaning-factualism and argue that the argument presents a genuine challenge to account for the guiding role of meaning in linguistic action. I then present a proposal regarding how this challenge may be met. This proposal is then compared to recent work by Ginsborg (2011; 2012), who has outlined an alternative view of the normativity of meaning that explicitly rejects the idea that meanings guide and justify linguistic use. I outline how Ginsborg utilises this notion of normativity in order to provide a positive account of what it is to mean something by an expression which is intended to serve as a response to Kripke’s semantic sceptic. Finally, I argue that Ginsborg’s response to the sceptic is unsatisfactory, and that, insofar as it is able to preserve our intuitive view of meaning’s capacity to guide linguistic action, my proposal is to be preferred.  相似文献

Pregnancy reflects a common experience for women in today's workforce, yet recent data suggest that some women scale back or leave the workforce following childbirth. Considering these effects on women's careers, researchers have sought to understand the underlying dynamics of these decisions. Here, we explore a paradoxical reason for weakened postpartum career attitudes: help that women receive during pregnancy. We integrate stereotype threat and benevolent sexism theories to explain how the effects of help on postpartum intentions to quit may be transmitted through reductions in work self-efficacy. In doing so, we consider the role of perceived impact—or the extent to which help interferes with versus enables women's perceived ability to continue performing their work role. Results of a weekly diary study of 105 pregnant employees suggest that work-interfering help led to decreased self-efficacy for work during the following week. Furthermore, there was an indirect effect of average help received at work during pregnancy on postpartum intentions to quit the workforce through reductions in work self-efficacy that was stronger insofar as help was work-interfering versus work-enabling. Taken together, our results highlight unintended negative consequences that occur when others provide ineffective support to women at work during pregnancy.  相似文献
