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

Objective

To describe an immobility reaction (IR) that was not previously reported at or immediately after birth in human newborns.

Method

We analyzed 31 videos of normal term vaginal deliveries recorded from Time 0 of birth defined as the as the moment that lies between the birth of the thorax and the pelvis of the infant. We searched for perinatal factors associated with newborn's IR.

Results

IR at birth was observed in 8 of the 31 newborns. The main features of their behavior were immobilization, frozen face, shallow breathing and bradycardia. One of the 8 newborns had sudden collapse 2 h after birth. We found significant relationships between maternal prenatal stress (PS) and IR (p = .037), and a close to significant one between infants’ lividness at Time 0 and IR (p = .053). The first breath of the 31 newborns occurred before and was not associated with the first cry (p < .001).

Discussion

The main features of IR at birth are similar to those of the universal most severe response to severe stress or danger. The relationship with PS suggests that children who had IR at birth might be at risk for similar disorders as those associated with PS. Sudden neonatal collapse of one of the IR newborns needs further research to determine if they are at risk for sudden infant death syndrome.

Conclusion

This first report of an IR reaction at birth in human infants could open up new paths for improving early neonatal care. Further research is needed for maternal PS, stress hormones, umbilical cord blood pH measurements in IR newborns. The challenge of education and support for parents of IR newborns is outlined.  相似文献

The purpose of this study was to examine whether anxious shyness and regulated shyness, initially identified in the Chinese culture, is found in South Korean children, and to explore whether these two forms of shyness were differentially related to children's psychosocial functioning. Participants were 544 fourth to sixth grade children (251 girls, M age = 11.38 years old) who were recruited from an elementary school in Bucheon City, South Korea. Children's anxious and regulated shyness were measured using peers' nominations and teachers' ratings, whereas their social preference and social impact were assessed using peers' nominations. Parents rated their children's temperamental shyness and effortful control, and children self‐reported their loneliness and interpersonal concerns. The results of confirmatory factor analysis replicated the two factor model of shyness found in previous studies of Chinese children. Anxious shyness and regulated shyness were positively associated and were similarly related to temperamental shyness. Anxious shyness was negatively related to effortful control and social preference, and positively associated with self‐reported loneliness and interpersonal concerns, whereas regulated shyness was positively related to effortful control and social preference and negatively associated with loneliness and social impact. These results were generally consistent with prior Chinese findings and provided preliminary support for the construct validity of anxious and regulated shyness in another Asian culture that emphasizes interdependence and modesty.

Recent years have seen a rejuvenation of interest in studies of motivation–cognition interactions arising from many different areas of psychology and neuroscience. The present issue of Cognitive, Affective, & Behavioral Neuroscience provides a sampling of some of the latest research from a number of these different areas. In this introductory article, we provide an overview of the current state of the field, in terms of key research developments and candidate neural mechanisms receiving focused investigation as potential sources of motivation–cognition interaction. However, our primary goal is conceptual: to highlight the distinct perspectives taken by different research areas, in terms of how motivation is defined, the relevant dimensions and dissociations that are emphasized, and the theoretical questions being targeted. Together, these distinctions present both challenges and opportunities for efforts aiming toward a more unified and cross-disciplinary approach. We identify a set of pressing research questions calling for this sort of cross-disciplinary approach, with the explicit goal of encouraging integrative and collaborative investigations directed toward them.  相似文献

The research base linking meaning with physical health is significantly underdeveloped in comparison to that linking subjective well-being and physical health. We address this deficit by first providing an overview of the study of meaning, and then examining evidence of its positive relationship to physical health in a systematic review of relevant literature. We searched PsycINFO and PubMed databases for studies of varying design and populations, excluding studies that did not have clear measures of meaning and physical health and/or did not address their relationship. Overall, higher levels of meaning are clearly associated with better physical health, as well as with behavioral factors that decrease the probability of negative health outcomes or increase that of positive health outcomes. Methodological challenges and future directions are discussed.  相似文献

This study compared structural and individual factors related to persons who are homeless and how these factors affected their ability to utilize and benefit from available services. A qualitative case study design was used to conduct in-depth interviews with two participants receiving hospice care in a residence for the homeless. Results support previous findings that chronic homelessness is the result of multiple structural and individual factors that occur over time. Contrary to the literature on chronic homelessness, however, both participants were unique in their history of employment and strong desire to work, despite having limited work skills. Responses from both participants underscored the value of daily structure and meaningful occupation in residential addiction treatment.  相似文献
