Distinguishing between cognitive and somatic trait and state anxiety in children

The study was conducted to develop self-report measures of cognitive and somatic trait and state anxiety for children and to evaluate the utility of distinguishing between cognitive and somatic anxiety. Sixty-seven fourth grade children anticipated and then performed a mathematics task either in a high- or low-stress condition. While the children anticipated performing the task, measures of seven cognitive behaviors were obtained by means of both a think aloud procedure and a questionnaire. The results of the study indicated that reliable trait and state measures of cognitive and somatic anxiety were successfully developed. Further, the trait measures of cognitive and somatic anxiety were found to be relatively impervious to induced anxiety states. As expected, cognitive trait anxiety but not somatic trait or state anxiety was found to be related to task performance. High cognitive state and/or trait anxiety was found to be associated with more preoccupation and performance denigration as well as taking less of an analytic attitude toward the situation. Somatic trait and state anxiety were found to be associated with preoccupation. In general, the results support the construct validity of the measures developed and the utility of distinguishing between cognitive and somatic anxiety in children.     

Positive evaluation of stressful experiences

Two studies were conducted to test the hypothesis that the more stressful an experience is, the more positively it will be evaluated. Stressfulness was manipulated in the two studies by means of threat of shock, and both self-report and physiological measures of stress indicated that these manipulations were highly successful. In both studies subjects who were exposed to the more stressful situation evaluated their experience as significantly more worthwhile and somewhat more interesting than did subjects exposed to the less stressful situation. Furthermore, as expected, subjects did not like the high stress experience more than the low stress experience. Implications and qualifications of these findings are discussed.     

Counterfactual Production and Achievement Orientation in Competitive Athletic Settings1

Two studies examined the impact of achievement orientation on counterfactual production in competitive sporting situations. In Study 1, participants created counterfactuals after reading 4 vignettes. Results indicated that participants reading about winners created more subtractive and downward counterfactuals than did participants reading about losers, while participants reading about losers created more additive and upward counterfactuals than did participants reading about winners. In Study 2, using participants in 3-on-3 basketball games, achievement orientation interacted with game outcome to produce adaptive responses for participants who held a mastery orientation and maladaptive responses for participants who held an outcome orientation. In addition to achievement orientation, the margin of victory played an important role in determining the type of counterfactual produced. The implications of these findings are discussed.     

Risk-sensitive foraging theory and operant psychology.

Hastjarjo, Silberberg, and Hursh (1990) have presented data on the foraging behavior of rats and discussed it in terms of risk-sensitive foraging theory. Because risk-sensitive foraging theory is comprised of several different models, it does not lead to general predictions about when an organism should prefer a foraging option with high variance to a foraging option with low variance. Any comparison of data with the predictions of the theory must be based on an appropriate model. I draw attention to various experiments that are potentially relevant to the results reported by Hastjarjo et al. and show how the time period over which the organism must survive can influence a model's predictions about risk sensitivity.

推理判断中双重加工过程的协作与转换机制

推理判断中双重加工理论的发展经历了不同发展阶段, 早期主要对两个加工过程的定义及特征的关注, 当前转向对两者间的协作及转换机制的研究。本研究梳理了双重加工过程协作及转换机制的代表性模型及其相关实验支持证据, 综合归纳为以下三类模型：序列加工模型(Serial processing model)、平行竞争模型(Parallel competitive model)以及混合模型(Hybrid model), 并比较和论述了三类模型在两个加工过程的转换和协作机制、冲突探查的加工机制、偏差反应的解释机制上的异同, 以及三类模型各自面临的问题。     

全球生命伦理学:共识的瓦解(上)——对全球性道德的探求:生命伦理学,文化战争和道德多样性

探究道德差异的核心问题以及哪种道德意见被我们采纳,比如为了建立医疗保健伦理模式与决策方法比较传统与后传统、家族本位与个人本位之间的关系。考虑到以道德多元化定义当代人类处境,关于卫生保健政策和生命法则的反思是明智的。这个反思强调了俗世伦理学的道德多元化和为对自由和责任进行俗世化思考的结论之间分歧的意义。
