Computational explanation in neuroscience

According to some philosophers, computational explanation is proprietary to psychology—it does not belong in neuroscience. But neuroscientists routinely offer computational explanations of cognitive phenomena. In fact, computational explanation was initially imported from computability theory into the science of mind by neuroscientists, who justified this move on neurophysiological grounds. Establishing the legitimacy and importance of computational explanation in neuroscience is one thing; shedding light on it is another. I raise some philosophical questions pertaining to computational explanation and outline some promising answers that are being developed by a number of authors.     

Theory and Method of Marriage Therapy in Contemporary Africa

This paper describes the theory and practice of marriage therapy in use by the author in his marital therapy process across two regions of Africa. The approach is grounded on an inclusive theoretical perspective inspired by the notion of the basic virtues of a healthy marriage as understood in Africa, and the place of the role theory approach in intervening between opposing parties. The theme developed is that a viable contemporary African marriage therapy practice is derivable from this indigenous model. The major discussion highlights the key guiding orientations and processes in implementing such a practice. A comparative view of the Euro-American emphasis in couple therapy is presented as a background for identifying the difference between the Western and the African perspectives.An initial version of the paper was presented as a Guest Lecture to the members of Staff and Graduate Students of the School of Psychology of the University of KwaZulu-Natal, in Durban, South Africa. The author is grateful to Prof. Inge Petersen and her team of staff of the school for their invitation and encouragement.     

A general theoretical framework for the design of artificial emotion systems in Autonomous Agents

Autonomous Agents (AAs) capable of exhibiting emotional behaviors have contributed to the development of natural human-machine interactions in several application domains. In order to provide AAs with emotional mechanisms, their underlying architecture must implement an Artificial Emotion System (AES), a computational model that imitates specific facets of human emotions. Although several AES have been reported in related literature, their design is generally supported on several emotion theories, leading researchers to model and integrate isolated emotion components and mechanisms into the architectures of AES. This theoretical foundation of AES contributes to ambiguities in the analysis and comparison of their underlying architectures, which demands the definition of standards, design guidelines, and integrative frameworks. In this paper, we present a psychologically inspired theoretical framework designed to serve as a platform for the unification of AES' components, the comparison of AES, and the design and implementation of AES in AAs. We analyze common emotion-related requirements of AES, emotion components involved in the design of this type of computational model, and emotion theories that drive the design of most AES. The validation of this framework demonstrates its compatibility with current AES and its feasibility as a model for unifying multiple emotional theories.     

语言的隐喻视角下人类认知框架建构

随着以计算机隐喻为核心的第一代认知科学的弊端日益凸显,强调感知体验为认知构建核心作为主流思想的第二代认知科学在近几年获得了迅速发展。语言作为人类联结自身体验和外界事物的桥梁,在个体认知框架建构中意义重大。而人类语言的隐喻认知能力是构成认知系统的核心要素,也是人类思维活动反映抽象概念的重要方式。文章通过对语言的隐喻认知视角下人类认知框架建构机制的探讨,在指出当前研究中存在的缺陷和不足的基础上为将来研究提供相关思路。     

The dynamic framework of mind wandering revisited: How mindful meta-awareness affects mental states’ constraints

The dynamic framework of mind wandering (Christoff, Irving, Fox, Spreng, & Andrews-Hanna, 2016) is reviewed and modified through integrating the construct of mindful meta-awareness. The dynamic framework maintains that mind wandering belongs to a family of spontaneous thought phenomena. The key defining feature of mind wandering is ‘spontaneity’ which characterizes the dynamic nature of thoughts in the framework. The argument is made that incorporating the mindful meta-awareness construct modifies the dynamic framework as follows: (1) the framework’s criteria for mind wandering do not hold anymore as meta-awareness changes the relationship between thoughts and constraints, and (2) lucid dreaming can be categorized as unguided thought while at the same time being dependent on deliberate constraints. Finally, the application of this modified framework will be discussed in terms of the treatment of mental disorders related to spontaneous thought alterations, in particular depression and nightmares.     

I3模型视角下个体行为的表达机制

I³模型塑造了一个解释个体行为的理论框架, 认为所有的行为都来自刺激、驱力和抑制三个因素的组合, 任何一个因素都可以独立于其余两个而变化, 其结构是由一个结果(行为)、一个中介(行为倾向)和三个因素(刺激、驱力和抑制)组成的12条路径的综合模型。这12条路径通过描述18个问题来预测个体在具体背景下的行为机制, 比如攻击行为、进食行为等。为有效促进该理论的应用, 文章对该理论的合理性、科学性、独特价值, 以及存在的问题进行评价, 并进一步提出未来的研究方向。     

Ethical Problems in Planning for and Responses to Pandemic Influenza in Ghana and Malawi

Ethical problems are addressed in various ways within countries in planning for and response to pandemic influenza. Here we report on a qualitative study, in which 46 policymakers in Malawi and Ghana were interviewed on how they identified and resolved ethical problems. The study results revealed that ethical problems involving conflicts of values and choices were raised in reference to the extent and role of resources (inequities) and nature of public health interventions (intrusive measures), including the extent and processes of decision making, reasoning, and justification. There is a need for an ethical framework within pandemic preparedness plans to resolve and avert these problems.     

The functional‐cognitive framework for psychological research: Controversies and resolutions

The scientific goals, values and assumptions of functional and cognitive researchers have propelled them down two very different scientific pathways. Many have, and continue to argue, that these differences undermine any potential communication and collaboration between the two traditions. We explore a different view on this debate. Specifically, we focus on the Functional‐Cognitive (FC) framework, and in particular, the idea that cognitive and functional researchers can and should interact to the benefit of both. Our article begins with a short introduction to the FC framework. We sweep aside misconceptions about the framework, present the original version as it was outlined by De Houwer (2011) and then offer our most recent thoughts on how it should be implemented. Thereafter, we reflect on its strengths and weaknesses, clarify the functional (effect‐centric vs. analytic‐abstractive) level and consider its many implications for cognitive research and theorising. In the final section, we briefly review the articles contained in this Special Issue. These contributions provide clear examples of the conceptual, empirical and methodological developments that can emerge when cognitive, clinical, personality and neuroscientists fully engage with the functional‐cognitive perspective.     

The influence of the human TMJ eminence inclination on predicted masticatory muscle forces

Aim of this paper was to investigate the change in masticatory muscle forces and temporomandibular joint (TMJ) reaction forces simulated by inverse dynamics when the steepness of the anterior fossa slope was varied. We used the model by de Zee et al. (2007) created in AnyBody™. The model was equipped with 24 musculotendon actuators. Mandibular movement was governed by the trajectory of the incisal point. The TMJ was modelled as a planar constraint canted 5° medially and the caudal inclination relative to the occlusal plane was varied from 10° to 70°. Our models showed that for the two simulated movements (empty chewing and unilateral clenching) the joint reaction forces were smallest for the eminence inclination of 30° and 40° and highest for 70°. The muscle forces were relatively insensitive to change of the eminence inclination for the angles between 20° and 50°. This did not hold for the pterygoid muscle, for which the muscle forces increased continually with increasing fossa inclination. For empty chewing the muscle force reached smaller values than for clenching. During clenching, the muscle forces changed by up to 200 N.
