The recognition of facial expressions in the first two years of life: mechanisms of development 总被引:3,自引:0,他引:3
C A Nelson 《Child development》1987,58(4):889-909
In recent years the infant's ability to recognize facial expressions of emotion has attracted considerable attention from developmental psychologists. The rationale guiding much of this research has been that this ability plays an important role in later socioemotional development. In the present article, the research relating to this topic is reviewed and synthesized. It is concluded that the recognition of facial expressions develops slowly over the first 2 years of life, and that even at the end of the second year the infant's understanding of facial expressions is still quite rudimentary. Following this review is a discussion of 2 unresolved issues regarding the development of this ability. 1 issue relates to the biological/experimental basis on which the ability to recognize facial expressions develops. Research with primates is brought to bear on this point, and useful analogues with human infants are sought. From this research it is suggested that a component of the ability to recognize facial expressions is unlearned, although experience of some as yet undetermined nature affects this biological readiness. The second issue relates to the possible neurological mechanisms that mediate this ability. Research with primates, normal adults, and brain damaged adults is used to support the speculation that a posterior region of the right hemisphere is responsible for mediating the recognition of facial expressions. 相似文献

This paper focuses on football fan rivalry in an African context using the case of Highlanders and Dynamos Football Clubs in Zimbabwe. It explores the intertwined historical, political and ethno-regional causes of this rivalry reflecting on how football reproduces underlying fractures that exist in society. Fan rivalries are an integral part of football across the world. Clashes between rival football teams are often highly charged encounters, resulting in cases of violence. As such the worst instances of football hooliganism are usually experienced during matches between rival football teams. Through the use of indepth interviews, internet research, key informant interviews and observation, we highlight the various dimensions and explanations of this rivalry. Often football becomes an outlay of wider societal conflicts. The stadium offers space for the playing out of these rivalries. Football rivalries thus offer a mirror into the socio-political tensions in society. Football in Africa is fraught with ethnic, racial, class and gender identities which often form the basis of rivalries. 相似文献

Published evaluations of career preparation of alumni from long-standing postdoctoral fellowship programs in the biomedical sciences are limited and often focus on quantitative analysis of data from extant publicly available sources. Qualitative methods provide the opportunity to gather robust information about specific program elements from structured postdoctoral training programs and the influence of this training on subsequent career paths of alumni. In-depth interviews with a subset of the National Cancer Institute’s Cancer Prevention Fellowship Program (CPFP) alumni (n = 27), representing more than 25 years of the program’s history and multiple career sectors, were conducted to assess alumni reflections on the training environment and career preparation during their time in the CPFP. NVivo software was used to analyze data and identify major themes. Four main themes emerged from these interviews, including: the value of structured training curriculum, mentorship, transdisciplinary environment, and professional identity. Even when reflecting on training that occurred one to two decades earlier, alumni were able to highlight specific components of a structured postdoctoral training program as influencing their research and career trajectories. These results may have relevance for those interested in assessing how postdoctoral training can influence fellows throughout their careers and understanding salient features of structured programs. 相似文献

Businesses have long relied on a variety of strategies to improve quality, efficiency, and service. Some ideas that have persisted over time are Six Sigma and Lean. While Six Sigma, originally intended for manufacturing, focuses on quality and Lean mainly addresses waste, many of the tools and principles involved can also apply to libraries. This article will review the literature on Lean and Six Sigma as they are used in business and then as they have been used in libraries. The resulting discussion will cover how the principles can be applied to better connect with stakeholders by mapping processes and discovering what is value added (VA) versus nonvalue added (NVA), anticipating failure modes using the failure mode and effects analysis (FMEA) framework, and implementing control plans to maintain quality processes and service. 相似文献
