抑郁倾向对合作的影响：双人同步近红外脑成像研究

抑郁人群不但表现出注意、记忆等个体认知层面的负性偏向, 还伴随有明显的社会认知障碍。已有研究在抑郁对社会认知的影响方面还考察得不多。本研究采用囚徒困境范式考察抑郁倾向对社会合作的影响。结果显示, 高抑郁倾向组比低抑郁倾向组的合作率更低, 双侧背外侧前额叶的激活更弱, 抑郁对右侧背外侧前额叶及眶额叶的脑间同步性有调节作用; 低抑郁被试与低抑郁被试配对时右侧颞顶联合区脑间同步性强于高抑郁被试与高抑郁被试配对, 或者高抑郁被试与低抑郁被试配对时的右侧颞顶联合区脑间同步性, 该效应当且仅当双方的选择相同时显著。结果表明, 抑郁群体在社会奖赏加工、冲突控制及心理理论脑区均存在功能性缺陷, 这些结果为理解抑郁人群合作意愿下降提供了脑成像证据。     

偏差声音干扰刺激对视觉注意网络系统的影响

结合注意网络测量工具和听视ODDBALL干扰范式,考察偏差声音干扰刺激的出现对注意网络系统不同功能的影响。结果发现,声音刺激序列下,视觉线索唤醒效应均消失; 标准声音刺激下,不存在线索的脱离和转移效应; 偏差声音刺激下,出现线索脱离和转移效应。研究表明,注意网络中的警觉功能具有超通道加工机制,偏差刺激下视觉注意系统中注意定向和线索转移效应的出现表明偏差干扰效应主要由偏差刺激引起的注意脱离和注意转移损耗部分引起。     

作为自由的法则：康德与“自律”观念的演绎

作为与纯然实践理性相结合的意志能力,康德的自律观念不仅具有独立于感性偏好的消极意旨,而且更强调确立普遍法则保障平等自由的积极取向,从而展现出独特的思想内涵。同时,在其具有普遍性、形式性特征的定言命令表述中,康德亦基于自律及其表征的人性目的使其呈现出规范性的价值旨趣,此阐释方式乃是回应相关论证以及指责的重要思想资源。此外,该方式还促使自律观念在行动中与道德法则相互契合一致,并通过其对自由的绝对价值以及道德人格理想的彰显,使定言命令论证的有效性得以可能。     

作为Liberal Arts的大学理念

现在,中国有学者在讨论大学理念,这是重要的问题.从晚清办京师大学堂至今,中国现代教育已有百余年的历史,这期间,所谓"大学理念"的问题一直混乱不堪,中国的大学教育走过的是不堪回首的曲折历程,有很多值得认真总结的经验教训.     

我们要给机器人以“人权”吗？

早先带有贬义的“机器人”，而今有人竟在考虑为它“立法”、为它争“人权”了。假如有一天你在敲打键盘时被控告为“攻击”、你要与新一代吸尘器一同去投票站参加选举，那该是何等尴尬。若机器人不断“进化”、“升级”、“自我复制”、“结婚生子”，当它们的智慧与才能有一天大到足以与人抗衡的地步，它们就可能转而与人类较量一番。 让机器人拥有“人权”，就是企图违背“机器人三大法则”，就是企图放纵机器人，就是间接地在危害人类。     

非目标工作记忆表征下颜色关联和抽象关联的注意捕获和抑制

采用工作记忆—视觉搜索双任务范式,探讨在非目标工作记忆表征下,颜色关联和抽象关联干扰子的注意捕获和抑制现象。实验一结果发现,颜色关联干扰子在快速反应阶段捕获注意,随后被成功抑制;抽象关联干扰子仍能捕获注意。实验二消除知觉凸显后,结果发现颜色关联条件的抑制消失,干扰子重新捕获注意。结果表明,有效抑制策略受不同关联干扰子加工先后顺序的影响,选择性抑制颜色关联干扰子,而颜色特征的凸显有助于抑制策略形成。     

Suicide and Its Association with Individual,Family, Peer,and School Factors in an Adolescent Population in Southern Taiwan

A representative sample of 10,233 adolescent students was recruited to examine the rate of suicidal attempt and its correlates in the adolescents living in southern Taiwan. Five questions from the Kiddie Schedule for Affective Disorders and Schizophrenia (Kiddie‐SADS‐E) were used to inquire about the participants' suicidality. The associations between suicidal attempt and multidimensional factors were examined by using logistic regression analysis: 9.1% of the participants reported a suicidal attempt in the preceding year. Female gender, low self‐esteem, weekly alcohol use, illicit drugs use, depression, high family conflict, low maternal education level, poor family function, low connectedness to school, low rank, poor feeling in peer group, and drop out from school were associated with adolescent suicidal attempt. The rate of suicidal attempt was found to be high in Taiwanese adolescents, and multidimensional factors were correlated to adolescent suicidal attempt.     

The influence of time units on the flexibility of the spatial numerical association of response codes effect

The Spatial Numerical/Temporal Association of Response Codes (SNARC/STEARC) effects are considered evidence of the association between number or time and space, respectively. As the SNARC effect was proposed by Dehaene, Bossini, and Giraux in 1993, several studies have suggested that different tasks and cultural factors can affect the flexibility of the SNARC effect. This study explored the influence of time units on the flexibility of the SNARC effect via materials with Arabic numbers, which were suffixed with time units and subjected to magnitude comparison tasks. Experiment 1 replicated the SNARC effect for numbers and the STEARC effect for time units. Experiment 2 explored the flexibility of the SNARC effect when numbers were attached to time units, which either conflicted with the numerical magnitude or in which the time units were the same or different. Experiment 3 explored whether the SNARC effect of numbers was stable when numbers were near the transition of two adjacent time units. The results indicate that the SNARC effect was flexible when the numbers were suffixed with time units: Time units influenced the direction of the SNARC effect in a way which could not be accounted for by the mathematical differences between the time units and numbers. This suggests that the SNARC effect is not obligatory and can be easily adapted or inhibited based on the current context.
