司马承祯《坐忘论》的养生观

司马承祯(公元646-735年),字子微,法号道隐,河内温(今河南温县)人。司马承祯为上清派茅山宗开创人陶弘景的四传弟子,师事潘师正,遂成为茅山宗第十二代宗师,传其符及辟谷导引服饵之术,享年八十九岁。一生历经唐代太宗、高宗、中宗、武后、睿宗、玄宗六朝,颇受唐代帝王礼遇,赠银青光禄大夫,谥“贞一先生”,玄宗亲为制碑文。司马承祯是道教学者,也是养生家。他精通医理,对养生有精到的论述,撰写了《坐忘论》、《修真秘旨》、《修生养气诀》、《服气精义论》、《天隐子》等养生专著,创建了一套以三戒、五渐、七阶为核心的养生理论。尤其在《坐忘…     

Suboptimal tradeoffs in information seeking

Explicit information-seeking actions are needed to evaluate alternative actions in problem-solving tasks. Information-seeking costs are often traded off against the utility of information. We present three experiments that show how subjects adapt to the cost and information structures of environments in a map-navigation task. We found that subjects often stabilize at suboptimal levels of performance. A Bayesian satisficing model (BSM) is proposed and implemented in the ACT-R architecture to predict information-seeking behavior. The BSM uses a local decision rule and a global Bayesian learning mechanism to decide when to stop seeking information. The model matched the human data well, suggesting that adaptation to cost and information structures can be achieved by a simple local decision rule. The local decision rule, however, often limits exploration of the environment and leads to suboptimal performance. We propose that suboptimal performance is an emergent property of the dynamic interactions between cognition and the environment.     

3-d interpolation in object perception: evidence from an objective performance paradigm

Object perception requires interpolation processes that connect visible regions despite spatial gaps. Some research has suggested that interpolation may be a 3-D process, but objective performance data and evidence about the conditions leading to interpolation are needed. The authors developed an objective performance paradigm for testing 3-D interpolation and tested a new theory of 3-D contour interpolation, termed 3-D relatability. The theory indicates for a given edge which orientations and positions of other edges in space may be connected to it by interpolation. Results of 5 experiments showed that processing of orientation relations in 3-D relatable displays was superior to processing in 3-D nonrelatable displays and that these effects depended on object formation. 3-D interpolation and 3-D relatabilty are discussed in terms of their implications for computational and neural models of object perception, which have typically been based on 2-D-orientation-sensitive units.     

Depression,Confidence, and Decision: Evidence Against Depressive Realism

This research examined how retrospective self-assessments of performance are affected by major depression. To test the validity of the depressive realism versus the selective processing hypotheses, aggregate posttest performance estimates (PTPEs) were obtained from clinically depressed patients and an age-matched comparison group across 4 decision tasks (object recognition, general knowledge, social judgment, and line-length judgment). As expected on the basis of previous findings, both groups were underconfident in their PTPEs, consistently underestimating the percentage of questions they had answered correctly. Contrary to depressive realism, and in partial support of the selective processing account, this underconfidence effect was not reduced but modestly exacerbated in the depressed patients. Further, whereas the PTPEs of the comparison group exceeded that expected on the basis of chance alone those of the depressed individuals did not. The results provide no support for the depressive realism account and suggest that negative biases contribute to metacognitive information processing in major depression.The results reported in this paper are based on an extension of the MSc dissertation of Tiffany Fu, conducted in partial fulfillment of the degree of MSc in Research Methods in Psychology, University of Reading, 2003

成人晚期自我觉知的日常问题解决能力及其与日常认知的关系

本研究采用老年人日常问题解决能力测验,对１８５名被试（５１￣７６岁）予以测定。研究发现：进入成人晚期以后,自我觉知的日常问题解决能力随年龄的增长呈现出一定的下降趋势,但未表现出显著的年龄组间差异,而其个体间差异却日益明显;再有,个体自我觉知的日常问题解决能力与日常认知之间存在较为一致的变化趋势。
