Quantum dynamics of human decision-making

A quantum dynamic model of decision-making is presented, and it is compared with a previously established Markov model. Both the quantum and the Markov models are formulated as random walk decision processes, but the probabilistic principles differ between the two approaches. Quantum dynamics describe the evolution of complex valued probability amplitudes over time, whereas Markov models describe the evolution of real valued probabilities over time. Quantum dynamics generate interference effects, which are not possible with Markov models. An interference effect occurs when the probability of the union of two possible paths is smaller than each individual path alone. The choice probabilities and distribution of choice response time for the quantum model are derived, and the predictions are contrasted with the Markov model.

墨子游鲁齐越宋卫楚考

墨子在鲁国自创学说,曾与多人辩论;然后曾至齐、越、宋、卫、楚等地游说,宣传“非攻”等思想主张。墨子晚年游说楚之鲁阳文君,止其攻郑,并老死于楚之鲁阳。     

人格特质对意识提取和无意识提取影响的实验研究

运用加工分离程序,该研究考察了神经质和内外倾对意识提取和无意识提取的影响,结果表明:1)被试的意识提取和无意识提取均存在显著个体差异;2)当意识与无意识分离以后,所有被试的无意识提取贡献都显著大于意识提取;3)神经质被试对正性词以及内外倾被试对外向词的无意识提取均有明显个体差异;4)内—外倾被试对相关特质词的意识提取的个体差异不如无意识提取显著。     

Support for exclusionism as an independent dimension of social dominance orientation in mainland China

Three studies using exploratory and confirmatory factor analyses provided consistent evidence for a three-factor model of the social dominance orientation (SDO) in Mainland China. Support for exclusionism, which was not found in previous research, emerged as an independent SDO factor (Studies 1, 2, and 3). In Study 2, this factor predicted SDO difference between a high status group (managers) and a low status group (entry-level employees). In Study 3, this factor correlated positively with authoritarianism and negatively with altruism. These results provided evidence for the validity of this new SDO factor. The findings are discussed in terms of their relations to China's cultural tradition and contemporary economic development.

影响大学生人际关系主观因素的初步研究

用自编的大学生人际关系主观因素问卷对800名1-4年级本科生进行调查。结果表明,影响大学生人际关系的主观因素涉及人际安全、人际疑虑、人际张力和人际报复;大学生的人际安全因子得分为3.86,人际张力、人际疑虑和人际报复因子得分和总均分在1.8-2.6之间;人际张力、人际疑虑、人际报复因子存在显著的年级差异(p<0.01);男生在人际报复因子上的得分明显高于女生;理科生的人际张力、人际报复和主观因素总均分显著高于文科生,人际安全因子得分显著低于文科生。表明大学生的人际安全感较强,人际交往和相处中的负性体验较弱,但存在年级、性别、专业等方面的差异。     

轻度认知功能障碍患者工作记忆中 脑电能量及皮质联络功能的变化特征

探讨轻度认知功能障碍患者（MCI）工作记忆状态下脑电能量及皮质联络功能的变化特征。被试为从社区选取的35名轻度认知功能障碍患者和34名健康志愿者。采用简单计算回忆方法,结果发现工作记忆加工过程中会引起4.0~18.0Hz范围内功率值的改变,且MCI组高于正常对照组;MCI患者在中央、顶、颞叶的半球间相干系数均显著高于正常对照组。研究结果提示MCI患者可能存在中央、顶、颞叶皮层的功能减退,工作记忆状态下通过代偿机制仍能维持加工的有效性     

Subtyping adolescents with bulimia nervosa

Cluster analyses of eating disorder patients have yielded a "dietary-depressive" subtype, typified by greater negative affect, and a "dietary" subtype, typified by dietary restraint. This study aimed to replicate these findings in an adolescent sample with bulimia nervosa (BN) from a randomized controlled trial and to examine the validity and reliability of this methodology. In the sample of BN adolescents (N=80), cluster analysis revealed a "dietary-depressive" subtype (37.5%) and a "dietary" subtype (62.5%) using the Beck Depression Inventory, Rosenberg Self-Esteem Scale and Eating Disorder Examination Restraint subscale. The "dietary-depressive" subtype compared to the "dietary" subtype was significantly more likely to: (1) report co-occurring disorders, (2) greater eating and weight concerns, and (3) less vomiting abstinence at post-treatment (all p's<.05). The cluster analysis based on "dietary" and "dietary-depressive" subtypes appeared to have concurrent validity, yielding more distinct groups than subtyping by vomiting frequency. In order to assess the reliability of the subtyping scheme, a larger sample of adolescents with mixed eating and weight disorders in an outpatient eating disorder clinic (N=149) was subtyped, yielding similar subtypes. These results support the validity and reliability of the subtyping strategy in two adolescent samples.
