Out of our skulls: How the extended mind thesis can extend psychiatry

The thesis that mental states extend beyond the skull, otherwise known as the extended mind thesis (ExM), has attracted considerable philosophical attention and support. It has also been accused of lacking practical import. At the same time, the field of psychiatry has remained largely unacquainted with ExM, tending to rely instead upon what ExM proponents would consider to be outdated models of the mind. ExM and psychiatry, therefore, have much to offer one another, but the connection between the two has remained largely unexplored. Here, I consider what implications ExM may have for psychiatry and, in so doing, reveal how psychiatry may lend practical import to ExM. First, I detail the possibility of the extension of one mental state relevant to psychiatry. I augment this example by surveying other possibilities for extension in the context of psychiatric diagnoses. I then consider ways in which such extensions might alter psychiatric diagnosis and treatment. Overall, I argue that recognition of the truth of ExM could alter the diagnostic status of certain individuals by correcting both false positives and false negatives, re-conceptualize certain aspects of treatment, help us re-envision psychiatric research, and potentially increase empathy towards those individuals considered to be mentally disordered or mentally different.     

Scaling properties of three-dimensional random fibre networks

Random fibre networks have unique mechanical properties and appear as the primary building blocks of many biological and structural materials. Although fibre networks are usually three-dimensional in nature, prior studies have mainly used simplistic two-dimensional models to characterize their properties. The present study creates a 3D strain-based nonaffinity measure and investigates the mechanical behaviour and scaling properties of 3D fibre networks. This measure is used to fully examine the influence of primarily characteristic length scales, i.e. mean segment length and bending length, on nonaffine mechanical behaviour of 3D filamentous networks. It is observed that all nonaffinity measure components exhibit a power-law variation with the probing length scale. Furthermore, it is found that while the degree of nonaffinity in both 2D and 3D systems decreases with increasing the probing length scale, the two power-law scaling regimes previously reported for 2D networks do not appear in 3D.     

Thinking sadly: In favor of an adverbial theory of emotions

Introspective as well as empirical evidence indicates that emotions shape our thinking in numerous ways. Yet, this modificatory aspect of emotions has received relatively little interest in the philosophy of emotion. I give a detailed account of this aspect. Drawing both on the work of William James and adverbialist conceptions of perception, I sketch a theory of emotions that takes these aspects into consideration and suggest that we should understand emotions as manners of thinking.     

On some common objections to a behavioral approach to psychological categories

This paper addresses several objections that have been leveled against a behavioral approach to psychological categories. It reconstructs and critically assesses (a) the so-called causal objection; (b) alleged counterexamples whereby one can exhibit the typical behaviors associated with a psychological phenomenon without exhibiting the latter, including Lewis’ “perfect actor” case and Kirk’s “zombie”; (c) alleged counterexamples whereby organisms can exemplify psychological phenomena without exhibiting any behavior associated with them, including Armstrong’s imagined brain in a vat, Putnam’s “super-super-spartans” scenario, and related cases; and (d) the holistic objection. Mistaken assumptions in each of these objections are pinpointed. The paper starts with a brief characterization of behaviorism about psychological categories and a summary of the particular version thereof supported here, which draws upon Ryle and Skinner, among others.     

Varieties of early modern materialism

ABSTRACT

This paper discusses how early modern materialism can be defined and delineated, before turning to a brief survey of the main philosophical resources early modern materialist theories draw on. Subsequently, I discuss competing overall narratives concerning early modern materialism, and conclude with a defence of the controversial view that material soul theories belong to materialism proper.     

Three Conceptual Models of Patient and Public Involvement in Standard-setting: From Abstract Principles to Complex Practice

Clinical practice guidelines have been critiqued for prescribing standardized care that neglects patients’ personal circumstances and knowledge in health care decisions. To make care more patient centred, standard-setters are urged to involve patients and the public in guideline development and use. Despite widespread principled support for such Patient and Public Involvement (PPI), the underlying principles guiding PPI in standardization of care are mired on confusion and contradiction. Based on the PPI literature in general, and informed by empirical research on guideline development, it is possible to identify three rationales that justify PPI in clinical standard setting. Each rationale gives rise to a conceptual model which outlines a distinct purpose of participation, who is to be included, and what they are expected to contribute. The Consumer Choice model aims to involve autonomous consumers to personalize clinical care. The Democratic Voice model aims for health care recommendations to better reflect collective values of citizens. The Lay Expertise model aims to re-contextualize universal evidence by including experiential patient knowledge. However, these models can and should not function as ‘Gold Standards’ to be consistently followed in practice. First, the models rely on two distinct types of representation, resulting in contradictory notions of how to be a good representative. Second, imposing models on practice requires a top-down control that is practically and politically problematic. Not only is control difficult to achieve, it may compromise the participatory ideal of participants co-determine practice, and may result in excluding the values and views of ‘real’ patients and public entirely.     

Religious identification and interreligious contact in Indonesia and the Philippines: Testing the mediating roles of perceived group threat and social dominance orientation and the moderating role of context

This study integrates three theoretical perspectives provided by social identity theory, realistic group conflict theory, and social dominance theory to examine the relationship between religious identification and interreligious contact. It relies on a unique dataset collected among Christian and Muslim students in ethnically and religiously diverse regions of Indonesia and the Philippines, where social cleavages occur along religious lines. Religious identification directly predicts a higher quality of interreligious contact, whereas it indirectly predicts a lower quantity and quality of contact, mediated by higher perception of group threat, and a higher quality of contact, mediated by lower social dominance orientation. Furthermore, these direct and indirect relationships are moderated by religious group membership and relative group size. We conclude that religious identification functions as a ‘double‐edged sword’ predicting both higher quality and lower quantity and quality of interreligious contact through various pathways and with a varying strength depending on intergroup context.     

父母的心理控制与儿童心理社会功能的关系

心理控制是一种侵入式教养,它是指父母使用引发儿童的内疚感、爱的撤回等方式侵入儿童思想和情感的教养行为,这种消极的、侵入式教养导致儿童产生诸多心理社会功能失调。跨文化研究发现,我国文化背景下父母的心理控制水平更高。社会环境、父母的人格和儿童的行为等因素都对父母的心理控制水平产生影响。父母的心理控制会对儿童的行为问题、自主性等一系列的心理社会功能产生消极影响。未来研究应立足中国特色文化,深入探讨儿童多重看护条件、儿童自身易感性等因素对心理控制效应的影响。     

宗教对信徒颜色认知的影响及作用机制:以中国台湾宗教信徒为例

采用自然分类法考察中国台湾佛教徒、道教徒、基督徒和非宗教信徒的基本颜色词分类,并做多维标度和聚类分析,以揭示宗教对信徒颜色认知的影响。结果发现,中国台湾三大宗教信徒对基本颜色词的分类既具有共性,又存在差异,宗教信徒与非宗教信徒的基本颜色词分类也存在着共性和差异,共性反映了汉语言和汉文化的影响,差异反映了宗教对颜色认知的影响。研究表明,颜色通过意象式传播方式影响信徒的颜色认知,支持颜色词与颜色认知的相互作用理论。
