情绪语音调节面孔表情的识别：ERP证据

采用事件相关电位（ERP）技术考察了情绪语音影响面孔表情识别的时间进程。通过设置效价一致或不一致的“语音-面孔”对,要求被试判断情绪语音和面孔表情的效价是否一致。行为结果显示,被试对效价一致的“语音-面孔”对的反应更快。ERP结果显示,在70-130ms和220-450ms,不一致条件下的面孔表情比一致条件诱发了更负的波形;在450-750ms,不一致条件下的面孔表情比一致条件诱发更正的后正成分。说明情绪语音对面孔表情识别的多个阶段产生了跨通道影响。     

乳头体和隔区在大鼠条件性味觉痕迹的形成和保存中的作用

本工作是在前一工作的基础上,进一步研究分别电损毁有关回路的乳头体、隔区,对以糖精水为条件刺激。氯化锂腹腔注射引起中毒作为非条件刺激的条件性糖精厌恶痕迹的形成和保存的影响。结果表明,无论是损毁乳头体,或者隔区,对条件性糖精厌恶痕迹的形成和保存均无影响。说明在本实验条件下,这种条件性味觉痕迹的形成与保存,不依赖边缘系统的乳头体、海马、隔区这些回路的参与,这就进一步说明味觉信号的记忆确有其不同于视、听觉信号的记忆的机制的。     

青少年学生自立人格的结构——基于中国人人格量表（QZPS）的结果

以中国人人格量表(QZPS)的项目为基础,经由大学生、高中生和初中生自己的挑选,编制出了探索青少年学生自立人格结构的<大学生问卷>、<高中生问卷>、<初中生问卷>和<青少年学生问卷>.分别对大学生、高中生和初中生进行调查和探索性因素分析后发现:①<大学生问卷>、<初中生问卷>与<青少年学生问卷>显示的自立人格都为个人责任(坚韧严谨)、个人主动(追求卓越)、人际开放(宽容随和)和人际主动(积极活跃);②<高中生问卷>显示的自立人格包括个人主动(追求卓越)、人际主动(积极活跃)、人际开放(宽容随和)、人际责任(坦诚记恩)和个人责任(坚韧严谨).最后,对青少年学生自立人格特质的分领域聚焦性等问题进行了讨论.     

Peat Bogs,Sperm, and Family Values: Teaching Naturalism Charitably

Introductory courses dealing with sex, gender and sexuality often assign excerpts from Thomas Aquinas as an exemplar of the naturalist view. Given that most novice students tend to side against such naturalism uncritically, they need to be exposed to a more charitable account of the biological considerations motivating a stance like Aquinas.’ With that in mind, this article presents accessible arguments aimed at restoring deliberative balance in the classroom.     

On Adjoint and Brain Functors

There is some consensus among orthodox category theorists that the concept of adjoint functors is the most important concept contributed to mathematics by category theory. We give a heterodox treatment of adjoints using heteromorphisms (object-to-object morphisms between objects of different categories) that parses an adjunction into two separate parts (left and right representations of heteromorphisms). Then these separate parts can be recombined in a new way to define a cognate concept, the brain functor, to abstractly model the functions of perception and action of a brain. The treatment uses relatively simple category theory and is focused on the interpretation and application of the mathematical concepts.
