工作记忆成分的年龄相关差异对算术策略运用的预测效应

采用选择/无选范式,借助工作记忆成套测验,在两位数乘法估算问题中探讨了工作记忆系统各成分对不同年龄段个体算术策略运用的预测效应。结果显示:(1)工作记忆的不同成分与年龄之间存在明显的相关。表现为,除视空模板成分外,其他各成分得分随着年龄增长而呈现上升趋势;(2)估算策略运用中,年龄与策略选择显著相关,表现为随着年龄增长,策略选择表现明显提高;(3)估算策略运用中,不同年龄个体的工作记忆不同成分和策略选择表现出不同的联系,中央执行均显示出显著的预测效应,语音环路和视空模板的预测效应均不显著。不同年龄个体的工作记忆不同成分对策略执行的预测效应均不显著。上述发现对于深刻理解工作记忆系统在算术认知策略运用中的作用机制具有重要理论含义。     

When Is More Better?

Abstract— We examine three determinants of the relationship between the magnitude of a stimulus and a person's subjective "value" of that stimulus: the process by which value is assessed (either by feeling or by calculation), the evaluability of the relevant magnitude variable (whether the desirability of a given level of that variable can be evaluated independently), and the mode of evaluation (whether stimuli are encountered and evaluated jointly or separately). Reliance on feeling, lack of evaluability, and separate evaluation lead to insensitivity to magnitude. An analysis invoking these factors provides a novel account for why people typically become less sensitive to changes in the magnitude of a stimulus as magnitude increases.     

体外循环所致炎性肺损伤机制及保护进展

肺损伤是体外循环心内直视手术的主要并发症之一。肺损伤的机制十分复杂,主要是全身炎性反应和缺血/再灌注损伤所致。肺保护的方法多种多样,其目的是降低全身炎性反应,减轻或避免缺血/再灌注损伤。本文探讨体外循环肺损伤的机制和保护进展。

信息的实在性与非实在性

If taking information as a philosophical concept, we will find an important philosophical problem: whether or not is it of reality? This problem also produces such a paradox: If we accept its reality, we will eliminate the difference between information and matter, and attribute information to a physical phenomena,or clear up the independent features, value and significance of information. But if we deny the reality of information, we will deny the objectivity of information or existence of any objective in...     

From glamour-oriented idolatry to achievement-oriented idolatry: A framing experiment among adolescents in Hong Kong and Shenzhen

The present study examined the framing effect of two modes of idolatry among a sample of 1095 secondary school students in Hong Kong and Shenzhen. Two experimental conditions were set up: in the glamour frame condition, subjects were exposed to frames that enhanced perfection and mystification of idols' personal or ideological characteristics; in the achievement frame condition, subjects were exposed to frames that enhanced emulation and identification of idols' pro-social behaviours or desirable dispositional traits. The experiment selected a prominent pop music and movie star well known in Chinese societies, Andy Lau, as the target idol. Subjects showed a consistently and significantly greater desire to glorify, idealize, identify with, emulate, and attach to Andy Lau in the achievement frame condition than in the glamour frame condition. The finding suggests that an achievement frame can heighten young people's adoration of an idol by emphasizing the idol's achievement processes. This suggestion is favourable to the possibility of transforming an idol into a role model for young people to learn to pursue career success.     

Confucian Moral Cultivation,Longevity, and Public Policy

By investigating the link between the Confucian ideal of longevity and moral cultivation, I argue that Confucian moral cultivation is founded on the ideal of harmony, and, in this connection, it promotes a holistic, healthy life, of which longevity is an important component. My argument is internal to Confucianism, in the sense that it aims to show these concepts are coherently constructed within the Confucian philosophical framework; I do not go beyond the Confucian framework to prove its validity. Finally, I show that if these Confucian beliefs are true, they have serious implications for public policy-making in contemporary societies.
