Mentoring is an essential part of success in the academic medical center. The provision of effective mentoring is key to the success of the increasing numbers of women entering medicine. However, the gender distribution within the hierarchy of medicine has not changed in that the power still resides with men in the system. Currently, men are attempting to mentor women, and so as the proportion of women in medicine continues to grow, they will become more influential in this setting and will become increasingly responsible for providing mentoring to men. In either case, effective communication across gender lines is an essential aspect of the mentoring process. Psychologists in academic medical settings can provide guidance to faculty and staff on the critical aspects of social development and communication, which may affect how women and men are mentored and the success of this mentoring process, whether across or within gender lines.  相似文献

Body image across the adult life span: stability and change   总被引:11,自引:7,他引:4  
Tiggemann M 《Body image》2004,1(1):29-41
By far, the majority of studies investigating body image in adults have drawn samples from college populations within a very narrow age range. The purpose of the present paper is to review empirical research on the body image of adults older than the typical college student. There are marked changes in appearance across the adult life span, especially for women, which lead to the expectation of concomitant changes in body image. In fact, the review found that body dissatisfaction was remarkably stable across the adult life span for women, at least until they are quite elderly. In contrast, the importance of body shape, weight and appearance decreased as women aged, underscoring an important distinction between evaluation and importance of the body. However, there are many large gaps and limitations in the current literature that will need to be addressed before a more complete understanding of the development of body image across the adult life span is achieved.  相似文献

Using experiences at Memorial University of Newfoundland as a basis, this essay suggests that leadership should be an expectation of professional academics in all the categories of their work, namely teaching, research and service. The desirability of developing the leadership of service in particular is advanced as an appropriate expectation for faculty members career progress. Developing a general leadership ethos is both philosophically appropriate and practically advantageous in collegial organisations.  相似文献

Perception, production, and understanding of sequences is fundamental to human behavior and depends, in large part, on the ability to detect serial order. Despite the importance of this issue across many domains of human functioning, the development of serial order skills has been neglected in developmental studies. The current article reviews evidence that the basic temporal and spatiotemporal skills that are necessary for the development of serial order skills emerge early in human development. The article then presents recent evidence from the authors laboratory showing that serial order perceptual skills emerge at the same time and improve rapidly. Consistent with a multisensory redundancy view of perception, when serial order perceptual abilities first emerge in infancy, they depend critically on the redundant specification of sequences in both the auditory and visual modalities. The findings suggest that infants ability to perceive the surface serial order characteristics of sequentially organized events provides the necessary antecedents to the development of more complex serial order skills that ultimately enable us to extract meanings from sequentially organized events and perform complex sequential actions.Edited by: Marie-Hélène Giard and Mark Wallace  相似文献

Four experiments examined the flexibility and stability with which children and adults organize locations into categories based on their spatiotemporal experience with locations. Seven-, 9-, 11-year-olds, and adults learned the locations of 20 objects in an open, square box. During learning, participants experienced the locations in four spatiotemporally defined groups (i.e., four sets of nearby locations learned together in time). At test, participants attempted to place the objects in the correct locations without the aid of the dots marking the locations. Children and adults displaced the objects toward the corners of the box consistent with the organization they experienced during learning, suggesting that they used spatiotemporal experience to organize the locations into groups. Importantly, the pattern of organization remained the same following a long delay for all four age groups, demonstrating stability. For adults, this organization shifted after a new pattern of spatiotemporal experience was introduced, suggesting that adults' categories based on spatiotemporal experience are quite flexible. Children only exhibited flexibility when the new pattern of spatiotemporal organization was consistent with available perceptual cues, demonstrating that the flexibility with which children organize locations into categories is intimately tied to both remembered and perceptual sources of information.  相似文献

Clinical interviews administered to third- to sixth-graders explored children's conceptualizations of rational number and of certain extensive physical quantities. We found within child consistency in reasoning about diverse aspects of rational number. Children's spontaneous acknowledgement of the existence of numbers between 0 and 1 was strongly related to their induction that numbers are infinitely divisible in the sense that they can be repeatedly divided without ever getting to zero. Their conceptualizing number as infinitely divisible was strongly related to their having a model of fraction notation based on division and to their successful judgment of the relative magnitudes of fractions and decimals. In addition, their understanding number as infinitely divisible was strongly related to their understanding physical quantities as infinitely divisible. These results support a conceptual change account of knowledge acquisition, involving two-way mappings between the domains of number and physical quantity.  相似文献

The Stroop paradigm was used to examine the role of phonological activation in semantic access and its development in reading Chinese characters. Subjects (age 7-23 years) of different reading ability were asked to name the display color of Chinese characters. The characters were displayed in four different colors: red, yellow, blue and green. There were five types of relationships between a character and its display color: semantically congruent, phonologically congruent, semantically incongruent, phonologically incongruent and neutral. In addition to the classical Stroop effects, interference and facilitation effects from the homophones of color characters were also observed. The younger children and those with lower reading ability exhibited stronger Stroop effects. These findings suggest that phonological codes are activated automatically in Chinese character recognition. Furthermore, there is more phonological activation in the semantic retrieval of children in lower grades and those with lower reading ability.  相似文献

Students report feeling safe to express and challenge their beliefs and assumptions in some classrooms and interactions but not in others. This paper proposes a definition of intellectual safety derived from student responses to their experience of safety or threat in college classrooms, and explores students' experience of intellectual safety in relation to epistemological development. Intellectual safety defined here has two components: epistemic fit or lack of fit between student and professor's epistemology, and moral climate. Students can be challenged in their world-views and feel either threatened, unsafe, and uncomfortable, or supported and safe despite possible discomfort. Experiencing an intellectually safe moral climate may create conditions and opportunities for epistemological reflection and change. Using concepts from moral theory, including moral type and moral perspectives of justice and care, I describe features of an intellectually safe moral climate during the cognitively and emotionally difficult time of epistemological development.  相似文献

Eating disorders (ED), including anorexia and bulimia nervosa, are chronic illnesses with periods of symptom exacerbation and remission. Because symptoms are usually present from 6 to 24 months before a diagnosis is made, aetiological agents are believed to be active well before symptoms appear. It is proposed that neuropsychological deficits in various cognitive domains preexist and underlie the aetiology of ED. This paper provides a comprehensive review of the literature relevant to neuropsychological deficits in ED patients and explores the relationship between cognitive deficits, psychosocial development, and the development of ED. Although the role of neuropsychological deficits in the evolution of ED requires further research, the proposed association has significant implications for clinical practice.  相似文献
