Aging and memory for expected and unexpected objects in real-world settings.

Adult age differences in the consistency effect were examined in 3 experiments. The consistency effect refers to items inconsistent with expectations being better remembered than items consistent with expectations. Younger and older adults walked into an office room and viewed objects that varied in their consistency with expectation. Immediate and delayed recognition tests on item information (i.e., distractors were defined by their semantic identity) revealed that both age groups recognized unexpected items better than expected items. However, when recognition of token information was requested (i.e., distractors were defined by their physical appearance), younger adults, in contrast to older adults, exhibited consistency effects. Also, under divided attention, young adults revealed the same pattern of data as did elderly adults under full attention. The results are discussed in terms of capacity-related differences in distinctive encoding.     

论葛洪的"君道"思想

葛洪《抱扑子外篇》卷五之《君道》,以儒家思想为主线,论述了"君臣"治国执政之道。葛洪的"君道"治政思想具有独特见解和系统观点,其基本思想和观点是儒道治政思想和理念的概括和总结,也是中国传统文化思想和内容的有机组成部分,具有重要的理论价值和现实意义。     

"气韵本乎游心"——道家"气"思想的心学意义

本文分别从认识论、实践论、心性论三个层面论述了道家气思想对气韵本乎游心这一美学命题的哲学基础性影响,归纳出道—气—心—性—德—虚静—美的命题,认为虚静之心无论对于宗教修炼还是艺术创作都是根本的起点和最终的极境,人之身心正是在虚静中才能体悟到道家之道、道教美学之美、内丹之仙、中国艺术之气韵。     

马修·阿诺德的“天人之策”

马修.阿诺德的《文化与无政府状态》既是一部文化批评名著,也是一部政治学名作。作者应时势之需要,赋予文化以政治教化的功能,以此来纠偏中产阶级的市侩习气,驯化底层民众的反抗精神,以力求社会摆脱陷入无政府状态的可能。阿诺德的对策固然有迂阔不实的一面,可他从文化角度去解决社会问题,对于20世纪新左派知识分子倡导的文化政治多有启发。     

Age-related changes in working and reference memory performance and locomotor activity in the Wistar rat

Wistar rats of three age groups were tested in an automated tunnel-maze system of variable geometry to investigate whether changes in spontaneous locomotor activity and in learning and memory develop differentially or in a correlated fashion as a function of age. Senescent (30 months) as well as mature-adult (17 months) rats showed an age-correlated decline of locomotor activity as compared to the mature-young (5 months) group. Both working-memory (measured as within-trial arm discrimination performance) and reference-memory (measured as avoidance of "blind alley" visits) were severely affected in the senescent group, whereas the middle-aged animals suffered only from a working-memory deficit. The findings provide evidence that locomotor deficits do not necessarily interfere in the assessment of age-related changes in cognitive performance. Furthermore the results support the hypothesis that working and reference memory have different underlying physiological correlates and that these neuronal systems are differentially affected by the aging process.
