视觉认知中的N170成分
The Component of N170 in Visual Cognition
 [PDF]

梁欣, 王权
Advances in Psychology (AP) , 2015, DOI: 10.12677/AP.2015.512099
Abstract:
N170是一个能够反映人脸或者字词等专家化刺激加工过程的事件相关电位,通常在刺激呈现后170 ms左右出现。目前关于N170的研究主要集中在人脸识别或者字词识别。发现对人脸和字词等专家化刺激具有敏感性。研究者们尝试用专家化理论去解释N170效应。N170还表现出偏侧化的特点。N170的研究范式繁多,可以从不同角度探讨N170成分。
N170 is a component of the event-related potential that reflects the processing of visual expertise stimulus such as faces and words, which shows increased negativity within 170 ms after stimulus presentation. The N170 is sensitive to visual expertise stimulus. Researchers are trying to explain the N170 effect with Visual Expertise Theory. The N170 also displays hemisphere lateralization. So far there are many research paradigms about N170, and these paradigms would provide different ways to explore the essence of N170 component.
论正字法规则性和熟悉性在语言认知中的作用
The Role of Orthographic Regularity and Familiarity Effect in Language Recognition
 [PDF]

张顺梅, 王权
Advances in Psychology (AP) , 2016, DOI: 10.12677/AP.2016.62014
Abstract:
语言认知是我们每天都要面对的事情,当我们面对大量以知觉形式呈现的语言符号时,如何将其转化为丰富的含义,是否有一些语言特性呢?本文通过查阅大量研究资料,从正字法规则性和熟悉性两个因素入手,阐述了正字法规则性和熟悉性在以词条的形式呈现的词汇认知中的作用以及在以句子呈现的语境条件下的作用,最后得出结论:正字法规则性和熟悉性在一定程度上可以影响词汇认知,但并非是影响语言理解的决定因素,在有语境的条件下,即使是无意义的字符串也可以进入语义加工通道。
Language cognition is something that we have to face every day. When we face a large number of linguistic symbols in the form of perception, questions are raised that how to convert it into a wealth of meaning, and whether there are some language peculiarities to help us understand the meaning. Through consulting a large number of materials, this paper expounds the role of ortho-graphic regularity and familiarity in cognitive vocabulary presented in the form of word list and in literature reading presented with the sentence context. Finally, the paper draws on that ortho-graphic regularity and familiarity are not the determining factors affecting language understanding though they have an effect on word recognition. And at least in a verbal context, semantic access may be attempted for any letter string, regardless of familiarity or regularity.
对称性视知觉的认知机制研究综述
A Review of Cognitive Mechanisms of Visual Symmetry Perception
 [PDF]

李健, 王权
Advances in Psychology (AP) , 2016, DOI: 10.12677/AP.2016.63028
Abstract:
人类视觉系统对于处理视觉输入刺激的两侧对称性十分敏感,许多研究者对对称性视知觉进行了广泛而深入的研究。从对称性知觉在视觉认知过程中的作用、对称性知觉的认知神经机制以及与之相关的认知模型等方面,文章总结近年来关于对称性知觉的实证和理论研究工作。结果显示,对称性知觉是一个包括通过多个滤波器进行预处理后,在高级视觉加工脑区进行信息整合,并在多个层面上与其他认知加工成分不断交互的开放性的视觉认知过程。
Human visual system is sensitive to the bilateral symmetry of the visual stimulus; many research-ers have done magnificent works on it. These researches include the attributes of symmetry per-ception, modulating factors in symmetry perception, the role of symmetry in perceptual organiza-tion, and its neural underpinnings. The purpose of the article is to outline and evaluate empirical and theoretical studies about human symmetry perception. This article mainly focuses on the role of symmetry perception in visual cognitive process and the cognitive model of symmetry perception. The result shows that symmetry detection is a versatile visual process that interacts with other cognitive processes, which include a preprocessing stage involving spatial filters followed by information integration across the visual field in higher-tier cortical areas.

 [PDF]

李丽军, 王权
Advances in Psychology (AP) , 2016, DOI: 10.12677/AP.2016.612161
Abstract:
本研究采用汉字作为材料,在语义启动比例一比三的条件下,两因素——汉字频率(高频、低频)和语义启动(启动、无启动)的被试内设计,使用同一字延迟判断任务,探究汉字字频与语义启动的作用。结果发现字频与语义启动出现了加法效应,支持多阶段激活模型。
This study uses Chinese characters as materials, in terms of semantic priming a scale of three, two factors concluding frequency (high frequency, low frequency) and semantic priming (start, no start) within subject design, and explores the effect of frequency and semantic priming of Chinese characters. The results show that word frequency and semantic priming are additive effect, and support the multistage activation model.

Advances in Psychology (AP) , 2016, DOI: 10.12677/AP.2016.62015
Abstract:
以视觉输入刺激进行的词汇加工能够诱发一个早期的事件相关电位(ERP)正成分P200,该成分起始于150 ms,结束于275 ms并在200 ms达到顶峰。P200成分作为一种内源性成分,其反映的词汇认知加工的内容和过程仍然存在较大的争论,P200可能既与字形加工,也与语音加工有关,且词汇加工和亚词汇加工都能诱发明显的P200;P200成分的复杂性更表现在它容易受到实验范式和任务的影响。将来的研究可以在实验范式和任务以及中英文材料在P200成分差异两方面进行拓展。
The visual P200 is a positive going electrical potential of the event-related potential measured at the human scalp which peaks at about 200 ms varying between about 150 ms and 275 ms induced by visual input stimuli. Research on the visual P200 is still keeping unclear about the time course and stage of lexical processing. The P200 may reflect the orthographic processing and phonologic processing simultaneously. Moreover, it both relates to lexical processing and sub-lexical processing. It appears to be easily modulated by a large and diverse number of cognitive tasks and paradigms. In conclusion, future research should be focused on experimental materials, research method and the difference between Chinese and English language system, etc.

Advances in Psychology (AP) , 2014, DOI: 10.12677/AP.2014.45093
Abstract:
运用自我参照研究中的R/K判断范式与UCLA孤独量表(第三版),采用2(孤独程度) × 3(参照条件)双因素实验设计,检验大学生的自我参照效应、朋友参照效应和自我包括朋友模型,初步探讨孤独感对大学生记忆参照效应的影响。结果显示:参照条件的主效应显著,自我参照大于朋友参照、鲁迅参照,朋友参照大于鲁迅参照,即大学生表现出自我参照效应和朋友参照效应,体现了自我编码、朋友编码的优势;但并未充分表现出自我包括朋友模型,一定程度上反映了大学生自我发展中的独立性;孤独感与参照条件的交互作用不显著,表明大学生表现出较为稳定的记忆参照模式。
The research adopted the R/K paradigm and the UCLA Loneliness Scale (the third edition) within a 2 (the degree of loneliness) ×3 (the condition of reference) two-factor design to test the self-ref- erence effect, the friend-reference effect, whether the self included friends of college students, and preliminarily tried to investigate whether the loneliness had an impact on memory-reference. Ac-cording to the results, we could come to the conclusion that the main effect of the reference-con- dition was significant such that the self-reference condition was higher than the friend-reference condition or the LuXun-reference condition, and the friend-reference condition was higher than the LuXun-reference condition, which meant that there were self-reference effect & the friend-ref- erence effect and reflected the advantage of self-reference coding and friend-reference coding; but it could not prove the model that the self included friends fully, which suggested college students were independent in the development of self; the interaction between the memory-reference and the loneliness was not significant, which meant the mode of the memory-reference was stable on some degree.

Abstract:
目的:探讨当代大学生的团体依恋与孤独感的关系。方法:用团体依恋问卷(ECR-G)和UCLA孤独感量表对301名本科大学学生进行调查研究。结果:性别变量和专业变量在团体依恋总分及其维度上的差异均不显著;年级变量在团体依恋上的得分具有显著差异;团体依恋与孤独感存在显著的正相关(R = 0.026**)。大学生团体依恋的团体依恋回避维度对孤独感有预测作用。
Objective: To investigate the relationship between group attachment and loneliness of college students. Methods: UCLA Loneliness Scale and the designed questionnaires about group attach- ment were used to investigate 301 college students. Results: There were no significant differences in gender variable or discipline variable among the group attachment and its two dimensions. Significant differences could be found in grade variable among the total share of group attachment. There was a significant positive correlation between the group attachment and loneliness of college students (R = .026**). The group attachment avoidance dimension of the group attachment could forecast the loneliness dependence.

The results suggest that the three dimensions of im-pulsiveness are all related with psychological health. This result suggests that we can improve the psychological health standard of the undergraduate students so that the impulsiveness would be controlled.
汉字模糊度、字频和语义启动在N400上的交互作用:N400的IA模型的证据
孙海静,王权
心理学报 , 2012,
Abstract: 通过两个实验, 采用事件相关电位技术, 记录大学生被试在同一字判断任务中的脑电波形。两个实验涉及三个因素, 包括模糊度、字频和语义, 语义和字频为被试内设计, 以启动字-靶字(模糊)-探测字的呈现序列为一个测试(trial), 要求被试判断靶字和探测字是否是同一个字。两个实验除了靶字的模糊度不同外, 其他材料完全相同。结果发现, 实验1字频和语义启动间存在交互作用, 其中低频条件下无语义启动比语义启动的N400波幅更偏负, 高频条件则无这种差异; 实验2中只存在语义启动效应, 字频与语义启动间不存在交互作用; 综合两个实验的ERP结果, 模糊度、字频和语义启动三者间存在交互作用, 且高频而非低频条件下模糊度与语义间也有交互作用, 无启动条件下字频和模糊度间也存在交互作用。本研究因此支持N400的IA模型(交互激活模型), 不支持核证模型和词汇后加工理论。
