A cognition paradigm clash: Simon,situated cognition and the interpretation of bounded rationality

Simon’s notion of bounded rationality is deeply intertwined with his activity as a cognitive psychologist and founder of so-called cognitivism, a mainstream approach in cognitive psychology until the 1980s. Cognitivism, understood as ‘symbolic information processing,’ provided the first cognitive psychology foundation to bounded rationality. Has bounded rationality since then fully followed the development of cognitive psychology beyond symbolic information processing in the post-Simonian era? To answer this question, this paper focuses on Simon’s opposition during the 1990s to a new (paradigmatic) view of cognition called situated cognition, which has since put into question the entire view in cognitive psychology of humans as symbolic information processors. This paper then reads the cognitivism/situated cognition debate through the lens of current bounded rationality research in economics, in order (i) to inquire into whether it has tackled the issues in that controversy; (ii) to envisage possible new foundations for a cognitive psychology-based bounded rationality.

基于使用的认知模型与商务语言动态性探析

本文从认知语言学的理论框架和基本知识点出发，从五个方面重点探讨了语言基于使用的认知模型的特点及其意义，以期更好地理解该模型的内涵和理论价值，并用于语言分析。这五个方面分别是语言知识的动态语义建构、语言知识的网络辐射结构、知识结构的图示化表征、语言的构式化体验结构，以及语言知识的文化观照。同时，结合以上研究，我们对商务语言的动态性特点做了针对性分析。     

认知工具与劣构问题解决探析

基于计算机的认知工具多维度地支持了人类的认知和思维发展。日常生活中,人们在不断地解决各种问题,其中多数是劣构问题,这些问题不同于学校教育中的良构问题。解决劣构问题能够发展人类的高级思维技能,形成专业技能和智慧。＂工欲善其事,必先利其器＂,认知工具作为人类思维的工具,促进了人类解决问题的效力。

基于TMS320VC5402的语音检测器

本文介绍的语音检测器以DSP芯片TMS320VC5402为核心，对短波电台接收到的信号进行分析和处理。数字语音信号采用串行输入／输出方式，语音检测算法则采用对语音信号进行降噪处理后，再进行短时平均幅度差和短时能量计算的方法。该语音检测器的电路简洁小巧，语音检测准确度高。     

Compulsory Ethics Education and the Cognitive Moral Development of Salespeople: A Quasi-Experimental Assessment

This study investigated several basic research questions suggesting a positive relationship between education and cognitive moral development. More specifically, these research questions examined the relationship between government mandated ethics education and cognitive moral development by testing the efficacy of a compulsory ethics intervention. Kohlberg's (1969, 1984) Cognitive Moral Development Theory was applied to test the efficacy of compulsory ethics education on the moral development of real estate salespeople used comparative statistical measures of ethical reasoning ability.The results of this research, while somewhat counterintuitive, suggest that the value of compulsory ethics education as an intervention to improve the moral reasoning of real estate salespeople is highly questionable. However, the results of the study do provide new insights into the relationship between ethics education and cognitive moral development.
