The Neurodynamics of Cognition: A Tutorial on Computational Cognitive Neuroscience

Computational Cognitive Neuroscience (CCN) is a new field that lies at the intersection of computational neuroscience, machine learning, and neural network theory (i.e., connectionism). The ideal CCN model should not make any assumptions that are known to contradict the current neuroscience literature and at the same time provide good accounts of behavior and at least some neuroscience data (e.g., single-neuron activity, fMRI data). Furthermore, once set, the architecture of the CCN network and the models of each individual unit should remain fixed throughout all applications. Because of the greater weight they place on biological accuracy, CCN models differ substantially from traditional neural network models in how each individual unit is modeled, how learning is modeled, and how behavior is generated from the network. A variety of CCN solutions to these three problems are described. A real example of this approach is described, and some advantages and limitations of the CCN approach are discussed.     

Human Cognition in Context: On the Biologic,Cognitive and Social Reconsideration of Meaning as Making Sense of Action

The aim of this special issue of IPBS has been to explore concrete and explicit alternatives to cognitivism. Indeed, in our editorial introduction we set out to give a brief survey of the numerous criticisms that have been made of understanding the mind this way (Ibáñez and Cosmelli, Integrative Psychological and Behavioral Sciences, 2008). Thus in what sense do the contributions here presented succeed in providing novel alternatives, moving into original and potentially generative domains of inquiry? While much remains to be done, we believe that they make significant headway in more than one sense. We do believe, however, that there is one locus that furnishes a convergence ground that is worth considering seriously: the problem of meaning. Meaning as making sense of contextualized action seems to cross the domains of intentionality, intersubjectivity and ecology of mind. The development of multilevel approaches, as the authors here exemplify, argues for a novel research agenda.     

Is a modular cognitive architecture compatible with the direct perception of mental states?

The Direct Social Perception Hypothesis maintains that we can perceive other people’s psychological states. Furthermore, it claims that doing so does not require any cognitive process that is simulative or theory-like, putting it in sharp contrast with mainstream accounts of social cognition. This paper contrasts the DSPH against the modular account of mindreading as proposed by Peter Carruthers and H. Clark Barrett. It maintains that the modularity view can respond to the challenges levelled by the DSPH, and that the positions are not as distinct as they originally appear. Finally, the paper discusses the role of non-folk psychological state concepts in our perceptions of other people.     

Empirically Informed Moral Theory: A Sketch of the Landscape

This introduction to the special issue on empirically informed moral theory sketches the more important contributions to the field in the past several years. Attention is paid to experimental philosophy, the work of philosophers like Harman and Doris, and that of psychologists like Haidt and Hauser.     

Effects of nicotine administration via a sublingual tablet on arousal and verbal ability in non‐smokers

Tobacco smoking or nicotine administration on its own can influence cognitive task performance. This study examined the effects of acute nicotine administration on verbal task performance and a physiological index of arousal. Healthy non‐smoking participants received either a 2‐mg sublingual nicotine tablet or placebo. Participants next completed various verbal tasks while heart rate recordings were taken concurrently. Nicotine increased heart rate relative to a pre‐administration baseline period, indicating that the new method of nicotine administration increased cardiovascular arousal. Nicotine was associated with reduced accuracy in a verbal matching task and reduced accuracy and increased reaction time in an anagram task, but had no effect on performance during an analogy or verbal fluency task. The data suggest that nicotine‐naïve individuals are unlikely to gain any benefit to their verbal ability from the single acute intake of nicotine, such as that obtained from cigarette smoking or by using nicotine replacement therapy products.

教育神经科学:探究人类认知与学习的一条整合式途径

教育神经科学是第二代认知科学对人的具身认知进行认识深化的必然产物,也是不同层面研究以整合态势来研究教育情境中人的认知过程及其发展的当然结果。在认知神经科学与教育已有的良好沟通下,教育神经科学就是要通过教育学家、心理学家、神经科学家等的合力,借助多种技术(包括脑成像技术),多视角、多层面地分析人的心理活动,以求最终达到科学改进教育理论及其做法的目的。不可否认,本研究领域还存在一些问题;但这并不会就此阻止教育学、心理学、神经科学加快合作与融合的步伐。     

Neural substrates for episodic encoding and recognition of unfamiliar faces

Functional MRI was used to investigate brain activation in healthy volunteers during encoding of unfamiliar faces as well as during correct recognition of newly learned faces (CR) compared to correct identification of distractor faces (CF), missed alarms (not recognizing previously presented faces, MA), and false alarms (incorrectly recognizing newly presented faces, FA). Encoding was associated with frontal, occipital/fusiform, thalamic, and cerebellar activation. CR produced activation in frontal and cerebellar regions, whereas CF activated frontal and occipitotemporal regions as well as the thalamus. In contrast, MA was associated with frontal and thalamic activation, and FA with frontal activation. The CR minus CF comparison showed left lateral prefrontal and parietal activation, while no suprathreshold positive signal changes were detected when subtracting the other conditions (CR minus MA, CR minus FA, and vice versa). These results support the view that the successful episodic retrieval of newly learned faces is based on a dorsal visual stream mechanism.     

Hope,Wholeness, and Helping the Flat to Grow Round

Abstract

The purpose of this article is to bridge the gap between neuroscience and psychotherapy so that there is greater understanding of how the objective biological processes of the brain affect interpersonal relationships and how relationship therapy can affect that biology. The research on emotional systems, implicit and explicit learning and memory are reviewed. Suggestions for therapeutic interventions include focusing on the changing the brain of each partner, reattaching through the therapeutic relationship, increasing physical activity, using nonverbal techniques, understanding the role of emotions in rational thinking, activating the left prefrontal cortex, using mindfulness techniques, and creating new experiences.
