Temporal restriction in apparent motion of two objects by presenting multipartite subframes

Two experiments tested whether proper perception of motion can be realized with a multipartite subframe stimulus. In order to elucidate the constructive processes of visual motion, two motion stimuli were used which differed according to their hierarchical levels of reference. It was found that: (a) stable motion was perceived so long as the temporal interval between the neighboring frames comprising several subframes was held between 30 and 120 ms; (b) visual unification of subframes was properly achieved independently of the number of subframes insofar as the temporal constraint mentioned above was satisfied; (c) when stimuli consisted of two motions of different hierarchical level of reference, perception of the higher-level motion required the prior perception of the lower-level motion.     

Structured propostions and sentence structure

It is argued that taken together, two widely held claims ((i) sentences express structured propositions whose structures are functions of the structures of sentences expressing them; and (ii) senteces have underlying structures that are the input to semantic interpretation) suggest a simple, plausible theory of propositional structure. According to this theory, the structures of propositions are the same as the structures of the syntactic inputs to semantics they are expressed by. The theory is defended against a variety of objections.I have benefitted from discussions with Michael Jubien, Michacl Liston, Paul Teller, Howard Wettstein, Mark Wilson and especially David Copp. The comments of Mark Richard and an anonymous referee for Journal of Philosophical Logic on an earlier draft resulted in a much improved paper. Various circumstances resulted in this paper appearing after King [1995], though the latter was written later and amends the present view in several ways. See notes 9, 13, 15 and 33 of King [1995].     

网络游戏中化身参照的加工优势：来自行为与ERPs的证据

采用R/K范式和事件相关电位技术(ERPs)分别从加工结果和加工过程考察网络游戏中化身参照的加工优势。实验1采用R/K范式比较40名玩家在不同参照条件下的记忆成绩。结果发现：化身参照的总再认正确率、R反应再认正确率和辨别力d'都显著优于他人参照, 初步证实化身参照的记忆加工优势。实验2借助ERPs内隐地考察网络游戏中20名玩家的化身参照在加工时间进程上的神经机制。结果发现：加工化身名字比熟悉他人名字诱发更大的P2 (160~260 ms)和P3 (370~600 ms)波幅, 比外国熟悉他人名字的P3潜伏期更短。结果表明, 相比较其他信息, 玩家不仅能够迅速注意到化身相关信息, 还对化身相关信息进行了更加精细和深入地加工。综上所述, 无论是记忆结果还是加工时间进程, 都存在网络游戏中的化身参照加工优势。     

I Was Pleased a Moment Ago: How Pleasure Varies with Background and Foreground Reference Points

The pleasure of an outcome is often evaluated relative to salient reference points. In the background, increasing sequences of positive outcomes are more enjoyable than decreasing sequences. In the foreground, outcomes that could have been worse are often more enjoyable than those that could have been better. How does pleasure vary when both background and foreground reference points are salient? Using a repeated gambling task in which participants make a choice, learn the outcome, watch their cumulative earnings change, and rate the pleasure of the outcome, we explore this question. Pleasure depends on background and foreground reference points, but the immediate events tend to dominate. The relatively narrow focus on the most recent reference points leads to myopic pleasure. We offer a modified version of decision affect theory to account for the results and explore the implications for consumer satisfaction.     

职中和高中学生的自我概念与内外参照模型

通过自我概念量表,对职业高中和普通高中一年级学生进行问卷调查,用多因素多元方差分析比较了这两类学生自我概念的差异;对学科成绩与学科自我概念做了分组相关分析,并做了,比较。结果表明：(1)职中生的自我概念显著低于高中生。(2)职中生与高中生的学科自我概念与学科成绩之间的关系有同有异,但都符合内外参照模型。     

中国老乡心理效应的理论探索与实证研究

老乡心理的本质是祖籍族群认同。中国人的老乡心理表现在离开家乡到外地后对家乡的怀念、对家乡人的依恋、对家乡方言的认同、老乡之间的相互帮助行为乃至老乡之间的组织行为。研究发现, 老乡心理效应由语言认同、文化认同、情感认同、习俗认同、地域认同等成分组成, 必备条件由中心因素和外围因素构成, 中心因素包括离家在外、地缘切近、文化趋同和相互扶持。采用群体参照效应的研究范式, 考察在本地和外地上学的大学生对老乡的参照效应, 发现被试在外地时, 参照本省(市)人加工的回忆成绩显著优于其他参照条件, 对本省(市)人表现出参照效应; 被试在本地时, 各参照条件下回忆成绩没有差异。老乡心理是形成区域心理性格的基础, 也是区域文化差异与人格差异相互作用的重要标志。老乡心理是民族认同、国家认同的心理基础。老乡认同的核心是社会文化认同, 社会文化认同以语言认同为内核。     

负期望条件下的末期效应：情绪动机诱发风险寻求

风险决策中, 末期效应指“个体在重复多轮决策任务的末尾冒险倾向升高”的现象, 但其内在机制尚不明确。三个研究的结果发现, 在实验室环境和自然环境下, 不同期望(负期望值和等期望值)条件下被试在最后一轮的投资均会显著增加, 末期效应稳定出现, 且不受到最后一轮决策前被试所拥有的代币数量的影响。即, 就算在风险选项收益更小的情况下, 被试也会倾向于在最后一轮选择高风险选项, 且这一效应是参照点独立的, 这说明末期效应的出现是源于对情绪满足感的追求。未来研究可从这一点切入, 进一步研究情绪影响风险决策过程的机制。     

老年人的朋友参照效应

采用自我参照效应范式探讨老年人朋友参照效应的特点。城市老年人和农村老年人各36人参加实验1, 结果表明：(1)城乡老年人都表现出朋友参照效应; (2)与农村老年人相比, 城市老年人朋友参照效应指标显著高于自我参照效应指标。城市教育程度较高与教育程度较低老年人各36人参加实验2, 结果发现, 与城市教育程度较低的老年人相比, 城市教育程度较高的老年人朋友参照效应指标高于自我参照效应指标, 表明教育程度对朋友参照效应有显著影响。由此推断, 老年人会将朋友包含于自我图式之内, 并且教育程度会影响朋友在自我图式中的地位。     

物体相似性对空间表征的影响：来自眼动的证据

以三维场景图片为实验材料,采用眼动追踪技术,通过两个实验考察了对称场景中物体相似性对空间表征的影响。结果表明：（1）无相似物体条件下,场景本身的内在结构对空间表征有重要影响,对称轴方向可以作为空间表征参照方向;（2）存在部分相似物体条件下,物体的相似性会影响空间表征参照方向的选择,并且相似物体方向也是空间表征的参照方向之一。
