Significant racial health disparities in infant mortality, preterm birth, and infant neurodevelopment exist in the United States. These disparities highlight a critical public health problem: Children of color are at a developmental disadvantage before birth. In this article, we describe how pregnant women from marginalized communities are disproportionately more likely to experience chronic stress in the form of discrimination, historical trauma, and acculturation. We integrate these understudied forms of chronic stress into allostatic load and prenatal programming models to describe how they can affect the health of two generations: the pregnant woman and her child. We describe psychophysiological ramifications of this early-life stress in infants of color. The prenatal programming field has largely ignored the experiences of women of color, and we highlight the need for researchers to include, or focus exclusively on, diverse samples in their research to reduce disparities that are evident at birth. 相似文献

When to Self-Correct Spelling Words: A Systematic Replication 总被引:2,自引:2,他引:0
Previous studies have consistently demonstrated self-correction to be more effective than traditional approaches to spelling instruction. This investigation examined the comparative effects of self-correction after attempting each word and self-correction after attempting a list of 10 words by six fifth-graders with learning disabilities or attention deficit-hyperactivity disorder. An alternating treatments design showed self-correction after each word to be more effective for (a) acquisition of new spelling words as measured by weekly spelling tests for five of the six students, and (b) maintenance of spelling words as measured by 1-week maintenance tests for all six students. 相似文献

An ongoing assumption made by sleep researchers is that since dreams are more often recalled on awakening from rapid eye movement (REM) sleep, dreams must occur more often during this stage of sleep. An alternative hypothesis is that cognition occurs throughout sleep, but the recall of this mentation differs on awakening. When a dream is not reported on awakening, there is no method of establishing whether it did not happen or was forgotten. The aim of the present study was to investigate this issue using an eye movement (EM) signal verification technique. Participants were instructed to produce an EM signal whenever they heard a tone. Tones were presented at increasing volume during Stage 2 and REM sleep until EM signal verification was observed. Ninety seconds after signal verification, participants were awakened and asked if they remembered hearing the tone or responding with the EM signal. Such recollection of signal verified tone (SVT) presentations was significantly less after Stage 2 sleep (65%) compared to REM sleep (100%) presentations. Furthermore, SVT recall was significantly correlated with reported dream recall frequency, suggesting the same processes involved in recalling SVTs might also underlie dream recall. 相似文献

Crews: A Distinct Type of Work Team 总被引:1,自引:0,他引:1
Distinctions among different types of work teams have been emerging in the theoretical literature as a key to understanding important work team processes. This has been precipitated by an increased appreciation of the importance of a work team's operating environment on such processes. Moreover, such distinctions are felt to be useful to practice in such areas as team staffing, training, and establishing leadership requirements. The present study investigates the concept of crews and contrasts it with other types of work teams by empirically assessing crewness, the extent to which a work team can be classified as a crew. A new scale of crewness was developed and administered to various collectives of workers including fire fighter crew members and project team members in order to establish the unique qualities of crews to show that they are a distinct type of work team. Construct and discriminant validity evidence is offered in support of the crewness scale. Approaches for further investigation of this distinction are also provided in order to guide both research and practice in this area. 相似文献

Current accounts suggest that self-referential thought serves a pivotal function in the human ability to simulate the future during mind-wandering. Using experience sampling, this hypothesis was tested in two studies that explored the extent to which self-reflection impacts both retrospection and prospection during mind-wandering. Study 1 demonstrated that a brief period of self-reflection yielded a prospective bias during mind-wandering such that participants’ engaged more frequently in spontaneous future than past thought. In Study 2, individual differences in the strength of self-referential thought — as indexed by the memorial advantage for self rather than other-encoded items — was shown to vary with future thinking during mind-wandering. Together these results confirm that self-reflection is a core component of future thinking during mind-wandering and provide novel evidence that a key function of the autobiographical memory system may be to mentally simulate events in the future. 相似文献

This was a troublesome case, without complete consensus about the right thing to do. It seemed there were arguments on both sides: those who thought that the goal of comfort care without treatment was most consistent with his wishes, versus those who thought the additional testing and treatment might have produced a net benefit in spite of the burdens. Ultimately, the patient was placed in a facility with a do-not-resuscitate (DNR) order in effect and a plan for comfort care. He may live a few months or more. We all hope that whatever time he has is spent free of pain and symptoms, and that he is able to live a life of quality consistent with his wishes. The main story line is consistent with actual events; however, there have been changes in terms of gender, disease, and relationships that have been included to protect the anonymity of the patient. 相似文献

A national, Web-based survey of 1,219 African American, Latina/o, Asian American, and European American psychology graduate students revealed both similarities and differences in experiences and perspectives. Mentoring was found to be the strongest predictor of satisfaction across groups. Academic supports and barriers, along with perceptions of diversity within the academic environment, were also important predictors of satisfaction. Students of color perceived less fairness of representation of their ethnic group within psychology than European American students, and a greater linkage between aspects of the graduate school experience and their ethnicity. Limitations of the study and implications for future research and action are discussed. 相似文献

This paper reverses the conventional migration lens to focus on the understudied case of a growing population of Americans in Canada. What motivates these native-born US citizens to migrate; how do they adapt to life north of the 49th parallel; what is the nature of the ties they maintain to their US homeland? Drawing on fieldwork in Ottawa, Toronto, and Vancouver, this paper identifies similarities between Americans and other migrants, but also points to a pervasive attitude of nonchalance as a notable difference. Examining migrants of relative privilege in North American helps refine theory rooted in assumptions of marginalization and advances analyses of continental integration. 相似文献
