On the optimality of serial and parallel processing in the psychological refractory period paradigm: Effects of the distribution of stimulus onset asynchronies

Within the context of the psychological refractory period (PRP) paradigm, we developed a general theoretical framework for deciding when it is more efficient to process two tasks in serial and when it is more efficient to process them in parallel. This analysis suggests that a serial mode is more efficient than a parallel mode under a wide variety of conditions and thereby suggests that ubiquitous evidence of serial processing in PRP tasks could result from performance optimization rather than from a structural bottleneck. The analysis further suggests that the experimenter-selected distribution of stimulus onset asynchronies (SOAs) influences the relative efficiency of the serial and parallel modes, with a preponderance of short SOAs favoring a parallel mode. Experiments varying the distribution of SOAs were conducted, and the results suggest that there is a shift from a more serial mode to a more parallel mode as the likelihood of short SOAs increases.

"儒"的自我理解——荀子说儒的意义

No matter what the original meaning of “Ru” was, looking at it from the perspective of the history of philosophy, the image of “Ru” as portrayed by other schools in the Warring States period was infused with the characteristics of Confucianism of that time. The self-understanding of Warring States Confucians expressed by their employment of the character “Ru” clearly displayed Ru’s character as well as the main points of the Ru school, namely Confucianism. In particular, the words and thoughts of Xunzi, the great Confucian master, on “Ru”, epitomize Pre-Qin Confucian’s understanding and expectations of themselves, and also reflect the Confucian new pursuit in facing the age of the unification of Qin.

制度伦理思想的传统溯源

制度伦理的兴起,在今天的中国是与社会主义市场经济的建立与发展紧密相联的。市场经济从根本上改变了传统社会的生产方式,从而动摇了传统德性伦理的生存土壤,致使德性伦理的边缘化。但由此就认为制度伦理是现代社会的产物,是市场经济的唯一形式显然又是有失偏颇的。追溯制度伦理文化的传统根源,对于我们弘扬民族文化和培育民族精神有一定的现实价值和借鉴意义。     

Post natal depression,the mother's conflict and parent – infant psychotherapy

This paper sets out to consider a psychodynamic approach to postnatal depression. In particular, it examines the advantages of psychodynamic parent?–?infant psychotherapy both as a treatment model, and also as a way of thinking that can help to formulate a theory of the postnatal period. An illustration is provided in the clinical account of the therapy of a couple and their nine-week-old infant. The author draws on this example, and on findings from psychoanalytic theory, infancy research, evolutionary biology and anthropology to suggest an integrated understanding of the postnatal state of mind and its challenges.
