Plugging the Leaks in Neurath's Ship: A Defense of Naturalistic Epistemology

This paper examines the question whether foundational epistemology (“FE”) can be replaced by naturalized epistemology (“NE”). First, it argues that Quine's defense of NE is inadequate since it is only based on arguments showing the impossibility of the logical empiricist version of FE rather than on arguments for the impossibility of FE as such. Second, it proposes that a more promising argument for the impossibility of FE can be found in the Münchhausen-trilemma which aims at showing that ultimate foundations (and, hence, FE) are unattainable. However, Karl-Otto Apel has shown that this trilemma is unconclusive since it uncritically presupposes the premise that all argumentation is deductive in nature. Apel's argument implies that FE is possible if and only if it is possible to devise a non-deductive foundation (“NDF”). It is argued, however, that the possibility of NDF cannot be demonstrated. This leads to a situation called the Multatuli-dilemma: we cannot prove the possibility of ultimate foundations nor can we prove the impossibility of ultimate foundations. This dilemma shows that the discussion about the possibility of FE is pointless. Thus, it suggests that it is legitimate to replace FE by NE. Barry Stroud and Henri Lauener, however, argue that this replacement is not feasible since NE is not capable of refuting scepticism (Stroud) or justifying methodological rules (Lauener). But these objections are shown to be mistaken: First, epistemological scepticism is practically impossible and, hence, does not pose a serious threat to NE. Second, NE is capable of justifying methodological norms if and only if it makes use of so-called internal justifications. Thus, the final conclusion of this paper is that FE can be replaced by NE. This revised version was published online in August 2006 with corrections to the Cover Date.     

Why Do Conceptual Analysts Disagree?

The practice of a priori conceptual analysis requires that the concept being analyzed be available in the analyst's mind. The difficulties of analysis and the existence of disagreements among analysts are explained by distinguishing the implicit knowledge we have of these concepts from the explicit knowledge we seek. This view of disagreement assumes that those who disagree are typically attempting to analyze a single shared concept. In this paper, reasons are developed for replacing this guiding assumption with the alternative assumption that members of a conceptual community often have similar, but not identical, concepts. Adopting this alternative requires that we rethink the nature and aims of conceptual analysis.     

Evaluating Environmental Arrangement as Setting Events: Review and Implications for Measurement

Environmental arrangement alters the physical, social, or programmatic aspects of classrooms to increase task engagement, facilitate prosocial behaviors, and reduce or prevent the challenging behaviors of children and youth. Research shows specific arrangements can affect student engagement and deportment, but this literature is not well integrated theoretically or empirically with other effective behavior change tactics. This article proposes that some environmental arrangements may serve as setting events for child behavior change. Setting events and environmental arrangement were defined and critically outlined. A total of 43 physical environmental arrangement articles were reviewed as to the specific type of arrangement and research methodology. Several methodological problems (e.g., lack of measurement or control of antecedents, consequences, or environmental arrangements, manipulation of more than one environmental arrangement) precluded conclusions about the setting event function of environmental arrangements. Suggestions for future research on setting events and environmental arrangements are proposed.     

Greatness and misery in the teaching of the psychology of learning

Overshadowed by more popular disciplines, the study of learning seems to have lost its prominent place in the undergraduate psychology curriculum. In the first part of this essay, we argue that one reason for this state of affairs is the current content of psychology of learning courses, namely, its disproportionate emphasis on facts, procedures, and everyday examples at the expense of functional and conceptual investigations. In the second part of the essay, we outline an alternative approach to the teaching of learning, one that emphasizes basic contents such as the conceptualization of learning as a biological adaptation or the study of temporal regulation, critical methodological issues such as the logic of experimental designs or the difficulties of measuring behavior, and broad epistemological problems such as the role of hypothetical constructs, the advantages of quantitative reasoning, or the origins of knowledge and its integration. By using learning as a means towards more fundamental ends, the splendor of the discipline and its prominent place in the undergraduate curriculum may be restored.     

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解,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。     

Stimulus generalization along a dimension based on a verbal concept

The present study examined generalization along a dimension based on a verbal concept of occupational status. The status dimension was scaled by students who placed occupation names into five status categories, Category 1 representing highest status and Category 5 the lowest status. In two experiments, key presses by students were occasionally reinforced when a slide showing an occupation name from Status Category 3 was present. For half the subjects, key presses were not reinforced during a name from Category 1; for the other half, presses were not reinforced during a name from Category 5. Occupation names from all status categories were later singly presented. In this generalization test, subjects typically divided the dimension into two parts, responding alike to all names within each part. The results suggest that generalization along a dimension in humans is mediated by a subject's verbal classifications of stimuli.     

Individual differences in harm-related moral values are associated with functional integration of large-scale brain networks of emotional regulation

Emotions affects moral judgements, and controlled cognitive processes regulate those emotional responses during moral decision making. However, the neurobiological basis of this interaction is unclear. We used a graph theory measurement called participation coefficient (‘PC’) to quantify the resting-state functional connectivity within and between four meta-analytic groupings (MAGs) associated with emotion generation and regulation, to test whether that measurement predicts individual differences in moral foundations-based values. We found that the PC of one of the MAGs (MAG2) was positively correlated with one of the five recognized moral foundations–the one based on harm avoidance. We also found that increased inter-module connectivity between the ventromedial prefrontal cortex, dorsolateral prefrontal cortex and middle temporal gyrus with other nodes in the four MAGs was likewise associated with higher endorsement of the Harm foundation. These results suggest that individuals' sensitivity to harm is associated with functional integration of large-scale brain networks of emotional regulation. These findings add to our knowledge of how individual variations in our moral values could be reflected by intrinsic brain network organization and deepen our understanding of the relationship between emotion and cognition during evaluations of moral values.     

Without Intuitions

This paper criticizes Analytic philosophy with its reliance on intuitions in pursuit of conceptual analysis. Rejecting naturalism as an alternative philosophical method, I offer in its place a pragmatic and revisionary conception of philosophical method. I explain the method of Analytic philosophy and show why reliance on intuitions is essential to that method, which is unable to provide substantive answers to philosophical problems. I further show that reflective equilibrium or wide analysis requires some criterion of intuition choice and that this criterion can be applied directly to definitions themselves.     

提取干扰对不同类型内隐记忆的影响

以往研究关于提取阶段的干扰是否会影响内隐记忆存在着异义, 其中一个重要因素可能源于所采用的内隐记忆测验类型的差异。本研究采用学习-测验范式, 通过4个实验, 分别考察了提取干扰对识别式知觉内隐测验、识别式概念内隐测验、产生式知觉内隐测验和产生式概念内隐测验的影响, 以期对提取干扰和内隐记忆之间的关系有着更全面的了解。结果表明: (1)词汇判断任务(识别式知觉)和语义分类任务(识别式概念)的启动效应在提取干扰下消失了, (2)而产生式词汇判断任务(产生式知觉)和产生式语义分类任务(产生式概念)在提取干扰下仍发现了明显的启动效应, 但与无干扰条件相比, 启动效应量也有着明显的减少。由此可见, 不同类型的内隐记忆都会受到提取干扰的影响, 相比于产生式启动, 识别式启动更容易受到提取干扰的破坏。     

Do liberals and conservatives use different moral languages? Two replications and six extensions of Graham,Haidt, and Nosek’s (2009) moral text analysis

Do liberals and conservatives tend to use different moral languages? The Moral Foundations Hypothesis states that liberals rely more on foundations of care/harm and fairness/cheating whereas conservatives rely more on loyalty/betrayal, authority/subversion, and purity/degradation in their moral functioning. In support, Graham, Haidt, and Nosek (2009; Study 4) showed that sermons delivered by liberal and conservative pastors differed as predicted in their moral word usage, except for the loyalty foundation. I present two high-powered replication studies in religious contexts and six extension studies in politics, the media, and organizations to test ideological differences in moral language usage. On average, replication success rate was 30% and effect sizes were 38 times smaller than those in the original study. A meta-analysis (N = 303,680) found that compared to liberals, conservatives used more authority r = 0.05, 95% confidence interval = [0.02, 0.09] and purity words, r = 0.14 [0.09, 0.19], fewer loyalty words, r = −0.08 [−0.10, −0.05], and no more or less harm, r = 0.00 [−0.02, 0.02], or fairness words, r = −0.03 [−0.06, 0.01].
