"心理理论"的实验任务与研究趋向

20世纪80年代以来,“心理理论”已成为发展心理学的研究热点和最活跃、最多产的领域。本文介绍了“心理理论”的涵义,解释为什么称之为“理论”,在作者自己实证研究的基础上,对“心理理论”实验任务进行了总结分析。主要从实验任务的角度探讨心理理论研究中存在的问题和认知与神经机制方面的发展趋向。     

注意力资源限制与双任务的相互干扰机制

采用心理不应期研究范式, 两个反应时实验检测了注意力资源分配的特征以及双任务的相互干扰机制。每次实验中, 要求被试快速、相继对高低音辨别任务(T1)和Stroop任务(T2)作出选择性反应, T1和T2间采用6种不同的时间间隔(SOA), 以系统考察不同SOA条件下两个任务的反应时走势。结果发现：(1) 在重叠的双任务情境中, T1的中枢加工导致在T2上出现显著的PRP效应, T2的中枢反应选择对T1的反应选择和反应执行加工同样产生显著的影响。SOA以及T2的难度与复杂度实质性地影响了T1的反应选择和反应执行加工。(2) 当两个任务同时需要进行中枢反应选择加工时, 一个任务占用更多的注意资源将导致另一任务获得较少的注意资源, 注意资源量的多寡直接决定了该任务的加工效率。(3) 两个任务的加工相互影响、相互制约, 这种制约机制不仅仅存在于中枢反应选择阶段, 在反应执行阶段仍然存在。     

内隐序列学习与注意的关系

内隐序列学习与注意的关系是内隐学习研究领域中的一个热点问题。“双注意机制”理论、“抑制表达”理论和“干扰外显学习成分”理论,从不同的角度阐释了内隐序列学习与注意的关系,但支持证据和反对意见并存,论争激烈。该文试图在一定程度上整合这三种理论,提出了“动态需求”假设,认为内隐序列学习任务对注意的需求是动态变化的,随着内隐序列学习任务中外显学习成分比重的变大,其对注意资源的需求也会随之增加     

论执行功能及其发展研究

执行功能(executive function,EF)是一个还没有明确定义的概念,但又是一个重要的概念,通常是指个体对思想和行动进行有意识控制的心理过程。目前的主要观点包括神经心理学观点、抑制控制理论、高级认知能力理论(包括工作记忆理论、抑制及工作记忆理论)和认知复杂性和控制理论。主要的研究任务类型包括卡片分类任务、延迟反应任务、基于Stroop任务的冲突反应模式任务、心理理论任务、问题解决任务、“热”执行功能任务等。未来的研究应着重弄清执行功能的本质,结合认知神经科学阐明其与脑神经结构和功能的关系,并从区分“冷”执行功能和“热”执行功能的角度,探讨以情感激活为特点的“热认知”在执行功能中的作用。     

一般性注意资源限制对返回抑制的影响

通过探讨视空间和语义通道内的注意资源的限制对IOR的影响的4个实验,来验证“IOR的低级成分不受注意资源限制的影响和IOR的高级成分受注意资源限制的影响”的假设。实验1A和1B的结果表明,在基于空间位置的简单检测任务中,IOR的低级成分既不随语义通道内注意资源的减少而消减,也不随空间通道内注意资源的减少而消减。实验2A和2B结果表明,在基于客体特性的辨别任务中,IOR的高级成分既随语义通道内注意资源的减少而消减,又随空间通道内注意资源的减少而消减。因此,辨别任务中的IOR受一般性注意资源的限制。同时,实验结果还表明,IOR的高级成分对空间通道内的注意资源的需求要高于对语义通道内注意资源的需求     

注意促进效应：“一心两用”下的注意和记忆

注意促进效应表现为增加一个任务的注意资源会提高与之无关但是同时进行的记忆任务的表现。自提出后，研究者对其发生特点进行了大量研究，并提出了该效应的双任务交互模型。本文着重对近5年研究成果进行梳理，重新阐述了注意促进效应的产生机制，以及理论模型的新进展：双任务交互模型2.0，以期对“一心两用”下注意与记忆关系有更为全面和深入的认识。同时，从神经基础、测量指标和理论模型等方面提出了需要进一步探讨的问题。     

外表真实区别、表征变化和错误信念的任务分析

自20世纪80年代以来,“心理理论”已成为发展心理学的研究热点和最活跃、最多产的领域。为了分析和比较“心理理论”的实验任务,该研究以济南市3所幼儿园中的233名3—6岁儿童为有效被试。进行了“意外转移。和“欺骗外表”两种心理理论实验任务。得出如下主要结论：(1)意外转移任务中内隐错误信念显著难于标准错误信念,易化错误信念与标准错误信念的难度不存在显著差异。(2)欺骗外表任务中外表真实区别难度显著低于表征变化和错误信念。(3)意外转移任务的错误信念显著难于欺骗外表任务的错误信念。     

连续报告任务中无效后线索对后线索效益的影响

本文采用连续报告任务,从非线索指示项目的角度入手,探讨无效后线索的存在是否会影响后线索效应的产生,以此进一步了解“后线索效益”的产生机制。结果表明,无论采用空间后注意线索,还是非空间的颜色后注意线索,都产生了“后线索效益”,即后线索确实提高了被试视觉工作记忆的表现。无效后线索的存在不会影响“后线索效益”的产生,该效益的理论解释符合优先提取说,即被试会利用后注意线索优先提取线索指示项目,产生更快和更准确的反应。     

仿真场景下类别空间关系判断中的注意分配

研究采用“提示-目标”的范式,并结合单、双任务的方法探讨仿真场景下类别空间关系判断中的空间注意分配。结果发现：提示影响类别空间关系判断效率,不同类型提示对类别空间关系判断的影响不同;类别空间关系判断还受到任务类型和判断类型的影响。由此得出以下结论：提示有助于注意资源的集中,提示越有效注意资源分配效率越高;注意分配受到第二任务要求的影响;决定注意分配策略的认知判断过程可能是持续存在的     

研究心理理论的新方法——失言识别任务

心理理论是对他人心理状态进行推论的能力。考察心理理论的经典范式是错误信念任务, 而青少年和成人在这种任务上可能出现天花板效应。为了测量青少年和成人的心理理论, Valerie E. Stone和她的合作者设计了失言识别任务。征求了Stone意见, 对失言识别任务的提出、构成、使用进行了介绍, 说明了该任务相对于经典范式的优势; 与此同时, 分析了失言识别任务范式存在的一些问题, 比如其效度指标问题, 与言语能力的分离问题, 失言识别任务与执行功能之间的分离等。未来研究可以尝试编制失言识别任务的本土化的量表, 并利用其探讨年长个体心理理论水平发展变化的规律。     

How to Understand the Completion of Art

There are a number of recent discussions on the question of when an artwork is complete. While it has been observed that a work might be complete in one way and not in another, the impact of this observation has been minimal. Discussion has been continued as if there is only one real sense of completion that matters. I argue that this is a mistake. Even if there were only one (or one most important) kind of completion, extant theories of completion would be bad candidates for that one kind. The best explanation of the failure of extant theories is that there are many kinds of completion, many corresponding senses of “completion,” and no kind of artwork completion is objectively more important than any other. We have a good reason to think that this is the case given the disparate interests we have when we ask completion questions. Once we have realized that those concerns track properties that are often unrelated, the question for theorists to answer becomes, “In how many ways can an artwork be complete?”     

On Using Ethical Theories to Teach Engineering Ethics

Many engineering ethics classes and textbooks introduce theories such as utilitarianism and Kantianism (and most others draw from these theories without mentioning them explicitly). Yet using ethical theories to teach engineering ethics is not devoid of difficulty. First, their status is unclear (should one pick a single theory or use them all? does it make a difference?) Also, textbooks generally assume or fallaciously ‘prove’ that egoism (or even simply accounting for one’s interests) is wrong. Further, the drawbacks of ethical theories are underestimated and the theories are also otherwise misrepresented to make them more suitable for engineering ethics as the authors construe it, viz. the ‘moral reasoning’ process. Stating in what various theories disagree would allow the students to frame the problem more productively in terms of motive–consequence or society–individual dichotomies rather than in terms of Kant–utilitarian.     

On the Explanatory Role of Correspondence Truth

An intuitive argument for scientific realism suggests that our successes in predicting and intervening would be inexplicable if the theories that generate them were not approximately true. This argument faces many objections, some of which are briefly addressed in this paper, and one of which is treated in more detail. The focal criticism alleges that appeals to success cannot deliver conclusions that parts of science are true in the sense of truth-as-correspondence that realists prefer. The paper responds to that criticism, in versions proposed by Michael Williams, Michael Levin, and, especially, Paul Horwich, by arguing that critics typically stop at a shallow level of psychological explanation. If we probe more deeply we discover a genuine explanatory role for correspondence truth.     

The Ethics of Treating Animals as Resources: A Post-Heideggerian Approach

This paper describes the phenomenological ethics implicit in Heidegger’s later work. It is argued that these phenomenological ethics take the form of a perfectionist ethics in which one consciously resists the temptation to nihilistically enframe other entities as Bestand. Despite Heidegger’s reputation as an inferior animal philosopher, it is then argued that we can employ this ethics to improve our relationship with non-human animals. Specifically, our use of them in the agricultural setting is examined to determine whether or not our current practices are ethical according to Heidegger’s normative model. Ultimately it is concluded that, more often than not, animals are harmed both ontically and ontologically by our modern farming practices. We are called on instead to try to dwell meditatively with other entities, to be-with them in such a way that respects them as inexhaustibly meaningful instantiations of being as such. This requires changes to the way in which we satisfy our needs as consumers.     

DEFLATIONISM,CONSERVATIVENESS AND MAXIMALITY

We discuss two desirable properties of deflationary truth theories: conservativeness and maximality. Joining them together, we obtain a notion of a maximal conservative truth theory – a theory which is conservative over its base, but can’t be enlarged any further without losing its conservative character. There are indeed such theories; we show however that none of them is axiomatizable, and moreover, that there will be in fact continuum many theories of this sort. It turns out in effect that the deflationist still needs some additional principles, which would permit him to construct his preferred theory of truth.     

Contrasting Acquisition-Focused and Performance-Focused Models of Acquired Behavior

What is encoded during a learning experience? In a learning situation, a training (acquisition) phase is often followed by a test phase. Acquisition-focused models (most associative models) emphasize information processing that occurs during training and assume that only summary statistics (associative values) are retained to influence behavior during testing. Performance-focused models (a k a "computational" models) emphasize information processing that occurs at test and often assume fairly comprehensive memory of prior experiences. In this article, we contrast these two families of models. We note that neither family can claim unique support from the various learning phenomena commonly cited as favoring one or the other position. Within each family, there are highly diverse models that preclude blanket generalizations. However, the acquisition-focused view that subjects retain only summary statistics suggests unrealistically impoverished memories relative to the fairly veridical memories that clearly are formed. But this oversimplifying assumption of acquisition-focused associative theories is exactly what has made them superior to performance-focused models to date in stimulating research.     

Virtual HR: The impact of information technology on the human resource professional

Accelerated investment and innovation in information technology (IT) offers prospects for conducting business in ways that are radically different from the past. Despite the growing presence of IT within organizations, however, we do not have a clear understanding of how IT impacts the role of professionals. We address this issue by investigating how jobs in one professional occupational segment, human resources (HR) professionals are influenced by extensive use of IT within the human resource department. Specifically, we examine how HR professionals handle HR information as well as the expectations placed on them resulting from an increased reliance on IT. Our findings suggest that IT enables HR professionals to more efficiently access and disseminate information while it also influences what is expected of them. Implications and future directions are discussed.     

THE CONCEPT OF PHILOSOPHICAL EXPERIENCE

Abstract: We often speak about religious experience, and sometimes we speak about metaphysical experience. Yet we seldom hear about philosophical experience. Is philosophy purely a matter of theories and theses, or does it have an experiential aspect? In this article, I argue for the following three claims. First, there is something we might call philosophical experience, and there is nothing mystical about it. Second, philosophical experiences are expressed in something quite similar to what Kant called “aesthetic judgements.” Third, philosophical experiences are expressed by using words in what Wittgenstein called “secondary sense.” Finally, I try to show the educational significance of pursing philosophical experiences. Through articulating them one might find one's ground, and through articulating them in a less private and more universal form one might raise oneself to universality. Thus, in expressing philosophical experiences one aspires to speak in a universal voice.     

Kuhn’s notion of scientific progress: “Reduction” between incommensurable theories in a rigid structuralist framework

In the last two sections of Structure, Thomas Kuhn first develops his famous threefold conception of the incommensurability of scientific paradigms and, subsequently, a conception of scientific progress as growth of empirical strength. The latter conception seems to be at odds with the former in that semantic incommensurability appears to imply the existence of situations where scientific progress in Kuhns sense can no longer exist. In contrast to this seeming inconsistency of Kuhns conception, we will try to show in this study that the semantic incommensurability of scientific terms appears to be fully compatible with scientific progress. Our argumentation is based on an improved version of the formalization of Kuhns conception as developed in the 1970s by Joseph Sneed and Wolfgang Stegmüller: In order to be comparable, incommensurable theories need the specification of relations that refer to the concrete ontologies of these theories and involve certain truth claims. The original structuralist account of reduction fails to provide such relations, because (1) it is too structural and (2) it is too wide. Moreover, the original structuralist account also fails to cover important cases of incommensurable theories in being too restrictive for them. In this paper, we develop an improved notion of “reduction” that allows us to avoid these shortcomings by means of a more flexible device for the formalization of (partially reductive) relations between theories. For that purpose, we use a framework of rigid logic, i.e., logic that is based on a fixed collection of objects.     

Perception of ensemble statistics requires attention

To overcome inherent limitations in perceptual bandwidth, many aspects of the visual world are represented as summary statistics (e.g., average size, orientation, or density of objects). Here, we investigated the relationship between summary (ensemble) statistics and visual attention. Recently, it was claimed that one ensemble statistic in particular, color diversity, can be perceived without focal attention. However, a broader debate exists over the attentional requirements of conscious perception, and it is possible that some form of attention is necessary for ensemble perception. To test this idea, we employed a modified inattentional blindness paradigm and found that multiple types of summary statistics (color and size) often go unnoticed without attention. In addition, we found attentional costs in dual-task situations, further implicating a role for attention in statistical perception. Overall, we conclude that while visual ensembles may be processed efficiently, some amount of attention is necessary for conscious perception of ensemble statistics.
