【摘要】 在解析难度与知识作业难度操作定义的基础上,通过脑电实验证实:脑电功率谱与反应时两项实验效应指标可客观反映知识作业难度的变化趋势,反应时数据揭示主观赋值数量关系服从Stevens定律,并可作为修订主观判定量表的精确效标。同时,本文实验结果支持认知科学的实验研究方法与测试手段在经济与管理问题的研究中具有广泛应用前景的观点。更多还原

【Abstract】 On the basis of parsing difficulty and defining the difficulty of knowledge task,the difficulty of knowledge task can be expressed by the two indexes of brain electrical power spectrum and RT(response time) of EEG(electroencephalogram) experiment,and RT data proved that quantitative relationships of subjective evaluation obeyed Stevens Law,for validity criterion to recense scale of subject determinant.The RT data point the relationships of subjective evaluation of power function.Besides,the results approve the point that questions of management can be study with cognitive science experiment.更多还原
