右侧脑发育不全遗忘症患者的启动效应与右侧皮层的分离

采用ＷＭＳ－ＣＲ、ＷＩＳＣ－ＣＲ和４项内隐记忆任务（偏好、自由联想、字根补笔和字辨认）观察一例右侧大脑发育不全患者和两组正常对照的知觉性启动效应和语义性启动效应。发现该患者智力发育迟滞、记忆功能严重障碍,但两种启动效应正常。显示右侧大脑皮层发育不全不影响两种启动效应任务操作,启动效应与右侧大脑皮层分离。不支持Ｋｅａｎｅ等人认为知觉性启动效应的神经学基础在大脑皮层的结论。结合先的研究结果认为知觉性启动效应可能与基底神经节有关,语义性启动效应可能与左侧大脑皮层有关。     

右侧基底节损伤遗忘症患者的知觉性启动效应与语义性启动效应的分离与定位

采用偏好、自由联想、字根补笔和字辨认等4项任务观察一例单纯性右侧基底节损伤遗忘症患者和两组正常对照的启动效应。结果发现：（1）该患者知觉性启动效应障碍,而语义性启动效应正常。认为知觉性启动效应的神经学基础可能在基底节。（2）该患者知觉性启动效应与语义性启动效应分离。认为神经组织的损伤可导致不同形式启动效应的分离,提出内隐记忆或启动效应的不同形式可能存在不同的神经学基础。     

On the relation between justification of solution method and correctness of solution in statistical problem solving

The relation between the justification of a choice of solution method and the correctness of that choice in statistical problem solving was investigated. In the first of two studies 16 subjects were asked to think aloud while solving two statistical problems. The results showed that an incorrect choice of solution method was more common when subjects did not justify their choice of solution as compared to when they justified their choice with domain-specific knowledge. Study 2 employed an experimental design. A group of 20 subjects were instructed to provide a justification for each choice of solution method, while another group of 20 subjects received no such instructions. The results showed no difference between the groups with respect to number of correct choices of solution method. A qualitative analysis of the justifications in the instructed group showed that the justifications for incorrect solution methods were more often incorrect than subjects' justifications for correct solution methods. The results in Study 2 suggested that the association found between incorrect choice of solution method and lack of justification in Study 1 was not in the first place due to a strategical deficiency on the part of the subjects but due to a lack of domain-specific knowledge.     

On the alleged explanatory impotence/conceptual vacuity of substance dualism

In the last decade, there has been a notable upsurge in property (PD) and generic substance dualism (SD). By SD I mean the view that there is a spiritual substantial soul that is different from but variously related to its body. SD includes Cartesian, certain forms of late Medieval hylomorphic (e.g., Aquinas'), and Haskerian emergent SD. Nevertheless, some form of physicalism remains the majority view in philosophy of mind. Several fairly standard objections have been raised against SD, and SDists have been preoccupied with these objections. As a result, a potent objection has not been given the attention it deserves. The purpose of this article is to fill that lacuna by raising the visibility of this objection and providing plausible responses to it. First, I shall clarify the explanatory–impotence challenge and, second, provide defeaters against it. Note that several of the issues to follow apply both to PD and SD. I will focus mostly on SD, but sometimes PD is a part of the discussion in that certain arguments for and against PD indirectly affect SD. When it is important for me to note that either SD or PD is specifically being addressed, I will notify the reader.     

Is Intuition Necessary for Defending Platonism?

G?del asserts that his philosophy falls under the category of conceptual realism. This paper gives a general picture of G?del’s conceptual realism’s basic doctrines, and gives a way to understand conceptual realism in the background of Leibniz’s and Kant’s philosophies. Among philosophers of mathematics, there is a widespread view that Platonism encounters an epistemological difficulty because we do not have sensations of abstract objects. In his writings, G?del asserts that we have mathematical intuitions of mathematical objects. Some philosophers do not think it is necessary to resort to intuition to defend Platonism, and other philosophers think that the arguments resorting to intuition are too na?ve to be convincing. I argue that the epistemic difficulty is not particular to Platonism; when faced with skepticism, physicalists also need to give an answer concerning the relationship between our experience and reality. G?del and Kant both think that sensations or combinations of sensations are not ideas of physical objects, but that, to form ideas of physical objects, concepts must be added. However, unlike Kant, G?del thinks that concepts are not subjective but independent of our minds. Based on my analysis of G?del’s conceptual realism, I give an answer to the question in the title and show that arguments resorting to intuition are far from na?ve, despite what some philosophers have claimed.     

汉语言语产生中的词长效应

采用启动条件下的词汇命名和图片命名范式, 探讨在汉语言语产生中词长效应的产生机制, 考察概念激活、词条提取和语音编码对词长效应的影响。实验1和实验2表明, 词条提取过程并不影响在词汇命名中的词长效应, 支持多词素词整词通达表征的理论。实验3显示, 概念激活和语音编码共同影响在图片命名中的词长效应, 被试对长词的命名时间显著地长于对短词的命名时间, 对下属水平概念的词汇提取显著地慢于对基本水平概念的词汇提取。研究结果支持多词素词语音编码的序列性和基本水平类别优先习得的观点。     

非熟练潮-粤双言者的语义通达：来自听觉词加工的证据

采用听觉跨语言启动的语义判断范式, 考察非熟练潮-粤双言者的两种方言之间的语义通达方式。结果发现, 无论是以潮语词为启动词, 还是以粤语词为启动词, 当二者具有翻译关系时, 启动词均促进对目标词的识别, 但L1对L2的启动量比L2对L1的启动量大。当启动词与目标词具有语义联想关系时, 启动词亦能促进对目标词的识别, 但L1→L2与L2→L1的启动量差异不显著。整个研究表明, 非熟练潮-粤双言者的两种方言的词汇独立表征, 语义共享表征; 第二方言的词汇能够直接通达语义表征, 不需要以第一方言的词汇为中介, 但双言的词汇表征与语义表征的联结强度仍然存在着不对称性。     

Ships That Pass In The Night.

A major source of tension between Staddon's The new behaviorism and Baum's Review is that the former was written for a general audience but the latter evaluates it as a technical work. Be that as it may, the central issue—Skinner's conception of the role of theory in behavior analysis—is inadequately portrayed in both the book and the review. The two primary sources of difficulty arise from failures to honor Skinner's distinction between experimental analysis and interpretation and to appreciate Skinner's views on events that are not observable at the behavioral scale of measurement.     

Why Parents Matter!: The Conceptual Basis for a Community-Based HIV Prevention Program for the Parents of African American Youth

The Parents Matter! Program (PMP) is a community-based family intervention designed to promote positive parenting and effective parent-child communication about sexuality and sexual risk reduction. Its ultimate goal is to reduce sexual risk behavior among adolescents. PMP offers parents instruction and guidance in general parenting skills related to decreased sexual risk behavior among youth (e.g., relationship building, monitoring) and sexual communication skills necessary for parents to effectively convey their values and expectations about sexual behavior—as well as critical HIV, STD, and pregnancy prevention messages—to their children. We briefly review the literature concerning parental influences on adolescent sexual risk behavior and present the conceptual model and theoretical foundation upon which PMP is based.
