该研究以多属性职业选项为材料,采用计算机化的信息板技术初步考察了焦虑型个体在多属性决策过程中的信息加工特点,结果表明焦虑型个体与非焦虑个体的决策过程有所不同。主要表现在与非焦虑型的决策者相比,焦虑型的被试在决策过程中对职业属性的加工时间更长,加工的信息也更多;在决策前后他们对完成决策任务的信心水平评估都很低,但是在搜索模式上焦虑型的决策者与非焦虑型的决策者没有差别。在研究的讨论部分对焦虑型个体决策过程中信息加工特点的原因进行了分析。 相似文献

By means of more than a dozen user friendly packages, structural equation models (SEMs) are widely used in behavioral, education,
social, and psychological research. As the underlying theory and methods in these packages are vulnerable to outliers and
distributions with longer-than-normal tails, a fundamental problem in the field is the development of robust methods to reduce
the influence of outliers and the distributional deviation in the analysis. In this paper we develop a maximum likelihood
(ML) approach that is robust to outliers and symmetrically heavy-tailed distributions for analyzing nonlinear SEMs with ignorable
missing data. The analytic strategy is to incorporate a general class of distributions into the latent variables and the error
measurements in the measurement and structural equations. A Monte Carlo EM (MCEM) algorithm is constructed to obtain the ML
estimates, and a path sampling procedure is implemented to compute the observed-data log-likelihood and then the Bayesian
information criterion for model comparison. The proposed methodologies are illustrated with simulation studies and an example.

临床医生如何应对社会发展对医疗的影响 总被引:1,自引:0,他引:1
目前我国的网络及教育均有了长足的进步,信息量迅速增加,信息技术得到了充分的发展,人们获取信息的手段更加便捷,信息不对称较以前有了很大的变化,这些都对医学产生了重大的影响。临床医生必须及时认识到这种变化及发展,及时改变自己的学习、思维及医疗行为模式,这样才能根据不同情况做出最适合的医疗决策,才能更好地履行自己的职责。 相似文献

James E. Huchingson's Pandemonium Tremendum draws on a surprisingly fruitful analogy between metaphysics and thermodynamics, with the latter motivated through the more accessible language of communication theory. In Huchingson's model, God nurtures creation by the selective communication of bits of order that arise spontaneously in chaos. 相似文献

Televised advertising disclosures are supposedly designed to supply consumers with important information for decision-making. From the perspective of models of information processing, however, these disclosures may well be improperly conceived and executed. Disclaimers presented in other media are also challenged, though television represents a special case because of consumers' inability to control the processing situation (e.g., to study the disclaimer at length if desired) and because of the extensive use of disclaimers in this medium. In this study, televised advertising disclosures are examined experimentally and found generally to be ineffective. Resultant suggestions for researchers and policy-makers are developed. 相似文献

Two experiments were conducted to assess whether responses to helpers who used insensitive emotional support vary as a function
of the interaction between sex of participant and helper. We hypothesized that women would evaluate an insensitive female
helper and her behavior more negatively than they would an insensitive male helper. In Experiment 1, participants (N = 137) read conversations in which male or female helpers sought to comfort emotionally distressed friends. In Experiment
2, participants (N = 87) engaged in face-to-face interactions in which they were comforted by either a male or female helper who used insensitive
comforting messages. Overall, the results imply that women with deficient emotional support skills may be at high risk of
rejection by same-sex peers.
A preliminary report of Experiment 1 was presented at the biennial meeting of the International Association for Relationship
Research, Madison, WI, July, 2004. 相似文献

群际情境下向上社会比较信息对自我评价的影响 总被引:8,自引:1,他引:8
以大学生为被试作了两个实验,研究群际情境下向上社会比较信息对自我评价的影响。实验1的结果表明,对于多数派群体的成员来说,来自内群体的向上社会比较信息会提高其自我评价,即产生同化效应,而来自外群体的向上社会比较信息会降低其自我评价,即产生对比效应;对于少数派群体的成员来说,无论向上社会比较信息来自内群体还是外群体,都对其自我评价几乎不产生影响。实验2表明,多数派群体成员在自我评价上的内群体同化效应依赖于群际对比。 相似文献
