This prospective study evaluates emotional functioning and illness representations in 68 unaffected women (34 carriers/34
noncarriers) 1 year after predictive testing for BRCA1/2 mutations when offered within a multidisciplinary approach. Carriers had higher subjective risk perception of breast cancer
than noncarriers. Carriers who did not have prophylactic oophorectomy had the highest risk perception of ovarian cancer. No
differences were found between carriers and noncarriers regarding perceived seriousness and perceived control of breast and
ovarian cancer. Mean levels of distress were within normal ranges. Only few women showed an overall pattern of clinically
elevated distress. Cancer-specific distress and state-anxiety significantly decreased in noncarriers from pre- to posttest
while general distress remained about the same. There were no significant changes in distress in the group of carriers except
for ovarian cancer distress which significantly decreased from pre- to posttest. Our study did not reveal adverse effects
of predictive testing when offered in the context of a multidisciplinary approach. 相似文献

鬼谷子的测谎心理思想其目的在于帮助统治者考察权变、征召远近人才、谋划国家事物、献说陈情、决安危、定亲疏、察同异、辨真伪。其基本依据的是阴阳观。他认为阴阳是宇宙变化的一贯之道,把握了阴阳之道,就获得了开启人内心隐秘的基本原理。其所遵循的原则是:知己知人原则,隐秘性原则,把握时机原则。其具体技术有捭阖术,即根据阴阳变化原理提出的开启和闭藏的技术;钩言术,即通过语言表达的动静状态窥探他人内心情报的方法;飞箝术,是以激励、褒扬的言语诱导对方获得实情而抓住对方心理的一种测谎技术。揣摩术,又分揣术和摩术。揣术是根据情感的两极变化和惯常行为表现推测对方心理真实情报的方法。摩术是指将内在情感与外在符验相结合进行推测、切磋、体会获得对方真实情报的方法。 相似文献

McGinn RE 《Science and engineering ethics》2003,9(4):517-542
A survey on ethical issues in engineering was administered over a five-year period to Stanford engineering students and practicing
engineers. Analysis of its results strongly suggests that important disconnects exist between the education of engineering
students regarding ethical issues in engineering on the one hand, and the realities of contemporary engineering practice on
the other. Two noteworthy consequences of these gaps are that the views of engineering students differ substantially over
what makes an issue an ethical issue, while practicing engineers exhibit significant disagreement over what is the most important
non-technical aspect of being a responsible engineering professional in contemporary society. These divergences impede the
recognition of ethical issues and of specific moral responsibilities of engineers in concrete professional practice. It is
argued that the use of suitably refined and probing surveys of engineering students and practicing engineers about ethical
issues in engineering is an important although neglected empirical approach to the study of engineering ethics. Such an approach
can enhance the prevailing case study method and combat over-tidy theoretical-analytical approaches to the subject.
When a train arrives at a station in the London Underground, a public announcement cautions passengers to “mind the gap”,
i.e. heed the space between the station platform and the carriage while entering or exiting.

The Motivations to Volunteer: Theoretical and Practical Considerations 总被引:10,自引:0,他引:10
Why do significant numbers of people engage in the unpaid helping activities known as volunteerism? Drawing on functional theorizing about the reasons, purposes, and motivations underlying human behavior, we have identified six personal and social functions potentially served by volunteering. In addition to developing an inventory to assess these motivational functions, our program of research has explored the role of motivation in the processes of volunteerism, especially decisions about becoming a volunteer in the first place and decisions about continuing to volunteer. 相似文献

From an initial sample of 1,278 Italian students, the authors selected 537 on the basis of their responses to a self-report bully and victim questionnaire. Participants' ages ranged from 13 to 20 years (M = 15.12 years, SD = 1.08 years). The authors compared the concurrent psychological symptoms of 4 participant groups (bullies, victims, bully/victims [i.e., bullies who were also victims of bullying], and uninvolved students). Of participants, 157 were in the bullies group, 140 were in the victims group, 81 were in the bully/victims group, and 159 were in the uninvolved students group. The results show that bullies reported a higher level of externalizing problems, victims reported more internalizing symptoms, and bully/victims reported both a higher level of externalizing problems and more internalizing symptoms. The authors divided the sample into 8 groups on the basis of the students' recollection of their earlier school experiences and of their present role. The authors classified the participants as stable versus late bullies, victims, bully/victims, or uninvolved students. The authors compared each stable group with its corresponding late group and found that stable victims and stable bully/victims reported higher degrees of anxiety, depression, and withdrawal than did the other groups. The authors focus their discussion on the role of chronic peer difficulties in relation to adolescents' symptoms and well-being. 相似文献

Yurevich A 《Integrative psychological & behavioral science》2007,41(1):21-27
The author presents several arguments against Toomela’s (Culture of science: Strange history of the methodological thinking
in psychology. Integrative Psychological and Behavioral Science, 2007a, doi:, History of methodology in psychology: Starting point, not the goal. Integrative Psychological and Behavioral Science, 2007b, doi:) pessimistic thesis: “The last 60 years of research in psychology seems to have gone astray.” Nevertheless he admits that
Toomela’s article despite the excessively categorical assessments contained in it and the undue pessimism crowing its conclusion,
represents a substantial contribution to the highlighting of socio-cultural impact on various models of psychological cognition,
which lurks behind the international unification of globalizing science.

This study investigated the relevance of anxious attachment to the differentiation of psychologically distressed and non-psychologically distressed cardiac patients. Attachment is a biologically based behavioral system in which proximity to a special other is sought or maintained to achieve a sense of safety and security. Anxious attachment, as the name denotes, fails to achieve the function of attachment in the sense of individuals having little or no confidence in the availability of their attachment figures. Empirically, three scales (feared loss of the attachment figure, proximity seeking and separation protest) capture the features of anxious attachment as elaborated by Bowlby. These scales were administered to 178 cardiac rehabilitation patients drawn from the cardiac rehabilitation program of the Calgary General Hospital. The results indicate that feared loss and proximity seeking differentiated psychologically distressed from non-psychologically distressed patients. The implications of this finding for the understanding of psychologically distressed cardiac patients are discussed. 相似文献
