Genetic testing for inherited cancer risk has recently improved through the advent of multi-gene panels and the addition of deletion and duplication analysis of the BRCA genes. The primary aim of this study was to determine which factors influence the intent of individuals with a personal history of breast and/or ovarian cancer and negative or uncertain BRCA1 and BRCA2 testing to return to a hereditary cancer program for additional genetic risk assessment, counseling, and testing. Surveys were sent to 1197 individuals and 257 were returned. Of those participants who were planning to return to clinic, most cited having family members who could benefit from the test result as the primary motivation to return. Many participants who were not planning to return to clinic cited the cost of testing as a barrier to return. Cost of testing and concerns about insurance coverage were the most commonly cited barriers for the group of participants who were undecided about returning to clinic. Results from this study may be used to guide re-contact efforts by clinicians to increase patient uptake to return to clinic for up-to-date genetic risk assessment, counseling, and testing. 相似文献

This study investigated how spatial updating strategies affected the selection of reference frames in path integration. Participants walked an outbound path consisting of three successive waypoints in a featureless environment and then pointed to the first waypoint. We manipulated the alignment of participants’ final heading at the end of the outbound path with their initial heading to examine the adopted reference frame. We assumed that the initial heading defined the principal reference direction in an allocentric reference frame. In Experiment 1, participants were instructed to use a configural updating strategy and to monitor the shape of the outbound path while they walked it. Pointing performance was best when the final heading was aligned with the initial heading, indicating the use of an allocentric reference frame. In Experiment 2, participants were instructed to use a continuous updating strategy and to keep track of the location of the first waypoint while walking the outbound path. Pointing performance was equivalent regardless of the alignment between the final and the initial headings, indicating the use of an egocentric reference frame. These results confirmed that people could employ different spatial updating strategies in path integration (Wiener, Berthoz, & Wolbers Experimental Brain Research 208(1) 61–71, 2011), and suggested that these strategies could affect the selection of the reference frame for path integration. 相似文献

个人影响力在群体决策整合过程中的作用:对SDS理论的扩展 总被引:4,自引:0,他引:4
以往社会决策图式理论没有考虑决策群体中成员的地位、成员的价值取向和专长知识分布等决策者影响力因素对群体决策整合过程的影响。本文在考虑上述诸因素影响的前提下构建了决策者影响力函数,通过投资决策模拟实验,综合使用决策影响力函数和个体偏好分布来预测群体决策的结果。研究表明综合运用决策者影响力函数和修改后的社会决策图式理论比传统的理论能更准确和有效的预测群体决策。 相似文献

无意识工作激励是指由外部环境自动诱导出个体努力行为的过程,并且这种自动诱导的过程无法被个体所内省。目前已经被发现的无意识工作激励过程包括自动化评价,无意识行为模仿,态度、特质和刻板印象的激活,以及无意识目标激活等。从内在机制来看,镜像神经元理论可解释无意识行为模仿,无意识行为选择模型可用来解释无意识目标激励。未来应侧重研究无意识工作激励与有意识工作激励的关系,发展新的研究方法,并更深入地探索无意识工作激励的内在机制。 相似文献

A crucial prediction of perceptual load theory is that high perceptual load can eliminate interference from distractors. However,
Lavie et al. (Psychol Sci 14:510–515, 2003) found that high perceptual load did not eliminate interference when the distractor was a face. The current experiments examined
the interaction between familiarity and perceptual load in modulating interference in a name search task. The data reveal
that high perceptual load eliminated the interference effect for unfamiliar distractors that were faces or objects, but did
not eliminate the interference for familiar distractors that were faces or objects. Based on these results, we proposed that
the processing of familiar and natural stimuli may be immune to the effect of perceptual load. 相似文献

土地等基本自然资源的约束会造成实际经济增长水平趋于下降.本文基于新古典增长模型,就长三角地区的土地资源对经济发展的增长阻力进行了实证分析.计量结果显示,在1978-2006年间,由于土地资源的消耗而造成长三角地区总体经济增长速度平均每年下降了0.52%;上海和江苏的土地"尾效"分别为0.21%和0.18%.改变上述状况的一个有效途经就是调整经济增长中的要素结构,减少土地和资本的依赖程度,通过技术创新推动长三角地区的经济增长. 相似文献

小学生阅读迁移机制的初步研究--字词表征还是内容表征 总被引:2,自引:0,他引:2
探讨文章字词与内容在小学生篇章阅读迁移中的作用。结果发现,阅读水平和阅读条件均对阅读迁移效果有显著主效应。阅读水平低的被试的阅读准确性提高得更大;完全重复条件和词汇重复条件在阅读时间和准确性上都没有显著差异,完全重复条件下的阅读时间和准确性均比意义重复及无相关条件的阅读时间和准确性提高得更多;词汇重复条件下的阅读时间和准确性显著高于意义重复条件下的成绩;词汇相同的阅读准确性也显著高于无相关条件下的阅读准确性。据此,我们可以初步得出小学生的篇章阅读迁移主要依赖词汇表征,即词汇表征是小学生篇章阅读迁移的主要机制。 相似文献
