Readers construct at least two interrelated representations when they comprehend a text: (a) a representation of the explicit ideas in a text and the relations among them (i.e., a propositional representation) and (b) a representation of the context or situation to which a text refers (i.e., a discourse model). In a recent study, found evidence that readers' representations were structured according to propositional relations, but only in the left hemisphere. Both hemispheres, however, appeared to represent contextually relevant semantic information. The goal in the current study was to examine further the organization of explicit text concepts in the two hemispheres. We used an item-priming-in-recognition paradigm in combination with a lateralized visual-field manipulation. We found evidence for a propositionally structured representation in the left hemisphere, that is, priming effects that reflected the linear distance between primes and targets in the propositional structure of passages. We also found that the right hemisphere represented explicit text concepts, but we found no evidence that these concepts were organized structurally. In a second experiment, we found our item priming effects reflected the representation of text information in memory and did not reflect lexical-semantic priming at test. 相似文献

Although authorities advocate breastfeeding as the ideal form of infant nutrition, breastfeeding rates remain low among employed mothers in the United States. Utilizing a work-family conflict framework, specific time-based, strain-based, and behavior-based conflicts that can occur for women combining breastfeeding and employment are explored. Research indicates that these conflicts often lead to decreased breastfeeding durations, which result in costs for employers, mothers, and infants. The review links workplace interventions (e.g. prenatal education, lactation programs, support systems, job flexibility, and child care) to the types of conflict (e.g. time, behavior, and strain-based) that each intervention can reduce.

This article is based on a partial replication of a previous study in which the Childrens Personal Attributes Questionnaire (CPAQ) was administered to a European American sample of children. The sample of the current study included 328 African American adolescents who completed the CPAQs short form. Psychometric analysis indicated acceptable reliabilities on two of the three subscales, and gender differences were found. A factor analysis yielded three factors, each of which represented a combination of items from the three original subscales. In general, the results closely parallel those reported with European American samples. The findings are discussed in terms of the CPAQs suitability for an African American adolescent sample. 相似文献

Having a self is associated with important advantages for an organism.These advantages have been suggested to include mechanisms supporting elaborate capacities for planning, decision-making, and behavioral control. Acknowledging such functionality offers possibilities for obtaining traction on investigation of neural correlates of self-hood. A method that has potential for investigating some of the brain-based properties of self arising in behavioral contexts varying in requirements for such behavioral guidance and control is functional brain imaging. Data obtained with this method are beginning to converge on a set of brain areas that appear to play a significant role in permitting conscious access to representational content having reference to self as an embodied and independent experiencer and agent. These areas have been identified in a variety of imaging contexts ranging from passive state conditions in which they appear to manifest ongoing activity associated with spontaneous and typically 'self-related' cognition, to tasks targeting explicitly experienced properties of self, to demanding task conditions where activity within them is attenuated in apparent redirection of cognitive resources in the service of task guidance and control. In this paper, these data will be reviewed and a hypothesis presented regarding a significant role for these areas in enabling degrees of self-awareness and participating in the management of such behavioral control. 相似文献

Genetic Evaluation and Counseling of Couples with Recurrent Miscarriage: Recommendations of the National Society of Genetic Counselors 总被引:1,自引:0,他引:1

The objective of this document is to provide recommendations for genetic evaluation and counseling of couples with recurrent miscarriage (RM). The recommendations are the opinions of the multidisciplinary Inherited Pregnancy Loss Working Group (IPLWG), with expertise in genetic counseling, medical genetics, maternal fetal medicine, internal medicine, infectious disease, cytogenetics, and coagulation disorders. The IPLWG defines RM as three or more clinically recognized consecutive or non-consecutive pregnancy losses occurring prior to fetal viability (<24 weeks gestation). These recommendations are provided to assist genetic counselors and other health care providers in clinical decision-making, as well as to promote consistency of patient care, guide the allocation of medical resources, and increase awareness of the psychosocial and cultural issues experienced by couples with RM. The IPLWG was convened with support from the March of Dimes Western Washington State Chapter and the University of Washington Division of Medical Genetics. The recommendations are U.S. Preventive Task Force Class III, and are based on clinical experiences, review of pertinent English-language published articles, and reports of expert committees. This document reviews the suspected causes of RM, provides indications for genetic evaluation and testing, addresses psychosocial and cultural considerations, and provides professional and patient resources. These recommendations should not be construed as dictating an exclusive course of medical management, nor does the use of such recommendations guarantee a particular outcome. The professional judgment of a health care provider, familiar with the circumstances of a specific case, should always supersede these recommendations. 相似文献

A sample of 95 Latino career counseling clients of a social services agency voluntarily completed a demographic questionnaire, the American-International Relations Scale (Sodowsky & Plake, 1991), and a questionnaire designed to assess career self-efficacy (Bandura, 1977, 1986; Betz & Hackett, 1981). Acculturation and English language use predicted career self-efficacy, unlike years of residence in the United States, age, and educational level (p < .05). The Implications of the results to career counseling for Latinos are discussed. 相似文献

This study examined the relationship between quality of leader–member exchange and follower perceptions of work stress. It was proposed that followers in higher quality exchanges were less likely to perceive work stressors than followers in exchanges of lower quality. Data collected from 215 employees of a midsized public university substantially supported this proposition. Quality of leadermember exchange was negatively related to role conflict, role ambiguity, low job scope, lack of career progress, and lack of participation experienced by followers. 相似文献
