FEELING WITHOUT THINKING: LESSONS FROM THE ANCIENTS ON EMOTION AND VIRTUE-ACQUISITION

Abstract: By briefly sketching some important ancient accounts of the connections between psychology and moral education, I hope to illuminate the significance of the contemporary debate on the nature of emotion and to reveal its stakes. I begin the essay with a brief discussion of intellectualism in Socrates and the Stoics, and Plato's and Posidonius's respective attacks against it. Next, I examine the two current leading philosophical accounts of emotion: the cognitive theory and the noncognitive theory. I maintain that the noncognitive theory better explains human behavior and experience and has more empirical support than the cognitive theory. In the third section of the essay I argue that recent empirical research on emotional contagion and mirroring processes provides important new evidence for the noncognitive theory. In the final section, I draw some preliminary conclusions about moral education and the acquisition of virtue.     

Modeling and estimating recall processing capacity: Sensitivity and diagnostic utility in application to mild cognitive impairment

We investigate the potential for using latency-based measures of retrieval processing capacity to assess changes in performance specific to individuals with mild cognitive impairment (MCI), a reliable precursor state to Alzheimer’s Disease. Use of these capacity measures is motivated in part by exploration of the effects of atrophy on a computational model of a basic hippocampal circuit. We use this model to suggest that capacity may be a more sensitive indicator of the underlying atrophy than speed of processing, and test this hypothesis by adapting a standard behavioral measure of memory (the free and cued selective reminding test, FCSRT) to allow for the collection of cued recall latencies. Participants were drawn from five groups: college-aged, middle-aged, healthy elderly, those with a diagnosis of MCI, and a sample of MCI control participants. The measure of capacity is shown to offer increased classificatory sensitivity relative to the standard behavioral measures, and is also shown to be the behavioral measure that correlated most strongly with hippocampal volume.     

Chess as a Behavioral Model for Cognitive Skill Research: Review of Blindfold Chess by Eliot Hearst and John Knott

This multifaceted work on chess played without sight of the pieces is a sophisticated psychologist's examination of this topic and of chess skill in general, including a detailed and comprehensive historical account. This review builds on Hearst and Knott's assertion that chess can provide a uniquely useful model for research on several issues in the area of cognitive skill and imagery. A key issue is the relationship between viewing a stimulus and mental imagery in the light of blindfold chess masters' consistent reports that they do not use or have images. This review also proposes a methodology for measuring and quantifying an individual's skill shortfall from a theoretical maximum. This methodology, based on a 1951 proposal by Claude Shannon, is applicable to any choice situation in which all the available choices are known. The proposed “Proficiency” measure reflects the equivalent number of “yes—no” questions that would have been required to arrive at a best choice, considering also the time consumed. As the measure provides a valid and nonarbitrary way to compare different skills and the effects of different independent variables on a given skill, it may have a wide range of applications in cognitive skill research, skill training, and education.

Aristotle's De Anima: On Why the Soul is Not a Set of Capacities

Although it is common for interpreters of Aristotle's De Anima to treat the soul as a specially related set of powers of capacities, I argue against this view on the grounds that the plausible options for reconciling the claim that the soul is a set of powers with Aristotle's repeated claim that the soul is an actuality cannot be unsuccessful. Moreover, I argue that there are good reasons to be wary of attributing to Aristotle the view that the soul is a set of powers because this claim conflicts with several of his metaphysical commitments, most importantly his claims about form and substance. I argue that although there are passages in the De Anima in which Aristotle discusses the soul in terms of its powers or capacities, these discussions do not establish that the soul is a set of capacities.     

Working memory capacity predicts the beneficial effect of selective memory retrieval

Selective retrieval of some studied items can both impair and improve recall of the other items. This study examined the role of working memory capacity (WMC) for the two effects of memory retrieval. Participants studied an item list consisting of predefined target and nontarget items. After study of the list, half of the participants performed an imagination task supposed to induce a change in mental context, whereas the other half performed a counting task which does not induce such context change. Following presentation of a second list, memory for the original list's target items was tested, either with or without preceding retrieval of the list's nontarget items. Consistent with previous work, preceding nontarget retrieval impaired target recall in the absence of the context change, but improved target recall in its presence. In particular, there was a positive relationship between WMC and the beneficial, but not the detrimental effect of memory retrieval. On the basis of the view that the beneficial effect of memory retrieval reflects context-reactivation processes, the results indicate that individuals with higher WMC are better able to capitalise on retrieval-induced context reactivation than individuals with lower WMC.     

A sub-process view of working memory capacity: Evidence from effects of speech on prose memory

In this article we outline a “sub-process view” of working memory capacity (WMC). This view suggests that any relationship between WMC and another construct (e.g., reading comprehension) is actually a relationship with a specific part of the WMC construct. The parts, called sub-processes, are functionally distinct and can be measured by intrusion errors in WMC tasks. Since the sub-processes are functionally distinct, some sub-process may be related to a certain phenomenon, whereas another sub-process is related to other phenomena. In two experiments we show that a sub-process (measured by immediate/current-list intrusions) is related to the effects of speech on prose memory (semantic auditory distraction), whereas another sub-process (measured by delayed/prior-list intrusions), known for its contribution to reading comprehension, is not. In Experiment 2 we developed a new WMC task called “size-comparison span” and found that the relationship between WMC and semantic auditory distraction is actually a relationship with a sub-process measured by current-list intrusions in our new task.     

认知心理学视角下的医师告知义务探析

Ellis的ABC理论和Schachter的情绪认知理论及试验说明,个体的认知信念影响情绪和行为反应.也就是说,患者对疾病事件的认知评价直接影响着情绪和行为表现.因此,在认知心理学相关理论指导下,医师对患者履行告知义务时必须遵循准确性原则、个性化原则及艺术性原则等,让患者对疾病事件有充分的知情与信息掌握,帮助患者改变观察问题的角度,正确认知与评价疾病事件,进而以积极、健康的情绪和行为表现来配合医务人员的诊治.     

轻度认知功能障碍与颈动脉狭窄的相关性研究

为了探讨颈动脉狭窄与轻度认知功能障碍(MCI)的关系,选取轻度认知功能障碍病例89例,健康对照组100例,全部行颈动脉彩超检查及简易智能状态量表(MMSE),蒙特利尔认知量表(MoCA),临床痴呆量表(CDR),日常生活能力量表(ADL),汉密尔顿抑郁量表(HAMD)测评.结果发现轻度认知功能障碍组颈动脉狭窄发生率明显高于对照组,左侧发生率明显高于右侧.其中随着狭窄的严重程度增加,患者在延迟回忆、视空间与执行功能、计算力与注意力、语言能力方面评分显著下降.从这一结果可以看出轻度认知功能障碍与颈动脉狭窄密切相关.     

宗教研究的认知科学新取向

宗教认知科学是新近出现的从认知和进化的角度研究宗教的分支学科。主要有认知副产物和社会适应两种理论。认知副产物理论认为宗教信仰是人类认知倾向的副产物;社会适应理论认为宗教信仰促进群体的团结合作,是一个精巧的社会适应机制,有助于群体的自然选择。两种理论引发了系列的实验研究,由于宗教认知科学仍处于理论研究向实证研究的过渡阶段,未来需统一概念,加强实验范式的建立,更多地借助认知科学的方法和工具开展实证研究。
