In real life, behavior is influenced by dynamically changing contextual factors and is rarely limited to simple tasks and binary choices. For a meaningful interpretation of brain dynamics underlying more natural cognitive processing in active humans, ecologically valid test scenarios are essential. To understand whether brain dynamics in restricted artificial lab settings reflect the neural activity in complex natural environments, we systematically tested the auditory event-related P300 in both settings. We developed an integrative approach comprising an initial P300-study in a (...) highly controlled laboratory set-up and a subsequent validation within a realistic driving scenario. Using a simulated dialog with a speech-based input system, increased P300 amplitudes reflected processing of infrequent and incorrect auditory feedback events in both the laboratory setting and the real world setup. Environmental noise and movement-related activity in the car driving scenario led to higher data rejection rates but revealed comparable theta and alpha frequency band pattern. Our results demonstrate the possibility to investigate cognitive functions like context updating in highly adverse driving scenarios and encourage the consideration of more realistic task settings in prospective brain imaging approaches.

In a recent study, Becker and Elliott [Becker, C., & Elliott, M. A. . Flicker induced color and form: Interdependencies and relation to stimulation frequency and phase. Consciousness & Cognition, 15, 175–196] described the appearance of subjective experiences of color and form induced by stimulation with intermittent light. While there have been electroencephalographic studies of similar hallucinatory forms, brain activity accompanying the appearance of hallucinatory colors was never measured. Using a priming procedure where observers were required to indicate the presence (...) of one of eight target colors we compared electrophysiological correlates of hallucinatory color with brain states associated with other visual phenomena. Different target colors were accompanied by different patterns of EEG activation. However, in general, we found that the appearance of hallucinatory colors is preceded by a power decrease in the lower alpha band alongside an increase in gamma band frequencies. We argue that decreasing activity in the lower alpha band acts as a gating mechanism, inducing a switch in perception between different colors. The increasing gamma activation may correlate with the formation of a coherent conscious percept. (shrink)

Neuroarchitecture uses neuroscientific tools to better understand architectural design and its impact on human perception and subjective experience. The form or shape of the built environment is fundamental to architectural design, but not many studies have shown the impact of different forms on the inhabitants’ emotions. This study investigated the neurophysiological correlates of different interior forms on the perceivers’ affective state and the accompanying brain activity. To understand the impact of naturalistic three-dimensional (3D) architectural forms, it is essential to perceive (...) forms from different perspectives. We computed clusters of form features extracted from pictures of residential interiors and constructed exemplary 3D room models based on and representing different formal clusters. To investigate human brain activity during three-dimensional perception of architectural spaces, we used a mobile brain/body imaging (MoBI) approach recording the electroencephalogram (EEG) of participants while they naturally walk through different interior forms in virtual reality (VR). The results revealed a strong impact of curvature geometries on activity in the anterior cingulate cortex (ACC). Theta band activity in ACC correlated with specific feature types (rs (14) = 0.525, p = 0.037) and geometry (rs (14) = - 0.579, p = 0.019), providing evidence for a role of this structure in processing architectural features beyond their emotional impact. The posterior cingulate cortex and the occipital lobe were involved in the perception of different room perspectives during the stroll through the rooms. This study sheds new light on the use of mobile EEG and VR in architectural studies and provides the opportunity to study human brain dynamics in participants that actively explore and realistically experience architectural spaces.

IntroductionSpatial navigation is a complex cognitive function that declines in older age. Finding one’s way around in familiar and new environments is crucial to live and function independently. However, the current literature illustrates the efficacy of spatial navigation interventions in rehabilitative contexts such as pathological aging and traumatic injury, but an overview of existing training studies for healthy older adults is missing. This scoping review aims to identify current evidence on existing spatial navigation interventions in healthy older adults and analyze (...) their efficacy.MethodsTo identify spatial navigation interventions and assessments and investigate their effectiveness, four electronic databases were searched. Two independent reviewers conducted a screening of title, abstract and full-texts and performed a quality assessment. Studies were eligible if published in English, the full text was accessible, at least one group of healthy older adults was included with mean age of 65 years or older, three or more spatial navigation-related training sessions were conducted and at least one spatial ability outcome was reported.ResultsTen studies were included, only healthy older adults were assessed further. Studies differed in sample size, type of training, total intervention duration, and intervention period.ConclusionThe spatial navigation abilities addressed and the measures applied to elicit intervention effects varied in quantity and methodology. Significant improvements were found for at least one spatial ability-related outcome in six of 10 interventions. Two interventions achieved a non-significant positive trend, another revealed no measurable post-training improvement, and one study did not report pre-post-differences. The results indicate that different types of spatial navigation interventions improve components of spatial abilities in healthy older adults. The existing body of research does not allow conclusions on transferability of the trained components on everyday life spatial navigation performance. Future research should focus on reproducing and extending the promising approaches of available evidence. From this, valuable insights on healthy aging could emerge.Trial RegistrationThis scoping review was preregistered at Open Science Framework. (shrink)

La menzogna è irrinunciabile per vincere in politica? Davi ci spiega quali sono i meccanismi di persuasione a cui ricorrono taluni politici per farsi eleggere e quali le responsabilità di quegli elettori che scelgono comunque di votare chi sostiene anche ciò che non può essere vero. È indubbio che la comunicazione politica si rifaccia al simbolismo e al linguaggio delle favole; non necessariamente per occultare la realtà, ma più direttamente per esprimere con maggiore efficacia il suo messaggio. Alle celebri favole (...) di 'Biancaneve', 'Cenerentola', 'Il brutto anatroccolo' sono ricorsi infatti uomini politici del calibro di Berlusconi, Prodi, Nixon, Carter, Mitterrand e partiti quali la Democrazia Cristiana; l'hanno fatto per conquistare voti ma anche per attivare ampi meccanismi di consenso che attingessero direttamente dall'inconscio collettivo. Le conseguenze - ammonisce l'autore - possono essere molto serie, come nel caso dell'attuale politica americana che ha portato la manipolazione e l'inganno a essere riconosciuti come tratti identitari della presidenza di George W. Bush. (shrink)

In _The Idealism of Freedom_, Klaus Vieweg argues for a Hegelian turn in philosophy: Hegel’s idealism of freedom contains a number of epoch-making ideas that articulate a new understanding of freedom, which still shape contemporary philosophy.

In this book, linguists and philosophers combine to offer a unique insight not only into Grice's contribution to philosophy of language, but on his theories of natural and non-natural meaning, implicatures and the semantic-pragmatic distinction.

We highlight the need to focus on the underlying determinants and production mechanisms to fully understand the nature of facial expression of emotion and to settle the theoretical debate about the meaning of motor expression. Although emotion theorists have generally remained rather vague about the details of the process, this has been a central concern of componential appraisal theories. We describe the fundamental assumptions and predictions of this approach regarding the patterning of facial expressions for different emotions. We also review (...) recent evidence for the assumption that specific facial muscle movements may be reliable symptoms of certain appraisal outcomes and that facial expressions unfold over time on the basis of a sequence of appraisal check results.

Societies change; and sociology has, since its inception, described and evaluated these changes. This article proposes a revised theory of collective learning processes, a conceptual framework which addresses ways in which people make sense of and cope with change. Drawing on Habermas’ classic proposal, but shifting the focus from argumentation towards storytelling, it explains how certain articulations allow for collective learning processes (imagining more inclusive orders), while others block learning processes (imagining more exclusive orders). More specifically, the article points to (...) narrative genres (romance, tragedy, comedy and irony) which organize feelings and shape the social bond, proposing that ironic and tragic stories have the potential to trigger collective learning processes, while romantic and comic stories tend to block them.

I show that in his De motu animalium Aristoteles proposes a teleology of the practical on the most general zoological level, i.e. on the level common to humans and self-moving animals. A teleology of the practical is a teleological account of the highest practical goals of animal and human self-motion. I argue that Aristotle conceives of such highest practical goals as goals that are contingently related to their realizations. Animal and human self-motion is the kind of action in which certain (...) state of affairs that realize values are mechanized. (shrink)

Zusammenfassung Der Beitrag analysiert auf der Basis theoretischer Überlegungen sowie empirischer Ergebnisse Möglichkeiten und Grenzen einer „interkulturellen Öffnung“ von Sportvereinen, worunter Strukturanpassungen verstanden werden, die auf die Inklusion und Integration von Personen mit Migrationshintergrund zielen. Es wird gezeigt, inwiefern eine nachhaltige interkulturelle Öffnung der Vereine von der programmatischen Anbindung an den Vereinszweck, von der kontinuierlichen Behandlung in den Kommunikationswegen, von spezifischen Personalentscheidungen und der Kompatibilität mit der Organisationskultur abhängig ist.

This important and challenging book is the fruit of many years of engagement with Aristotle’s thinking about the soul-body relation by one of the most distingui.

Appraisal theories of emotion have had a strong impact on the development of theory and experimental research in the domain of the affective sciences. While there is generally a high degree of convergence between theorists in this tradition, some central issues are open to debate. In this contribution three issues have been chosen for discussion: (a) varieties of relevance detection, (b) varieties of valence appraisal, and (c) sequential-cumulative effects of appraisal results. In addressing these issues, new theoretical ideas are suggested (...) and an update of recent research on the sequence of appraisal processes is provided. Special emphasis is placed on nonverbal signatures of appraisal processes. (shrink)

The goal of this paper is to propose a unified approach to the split scope readings of negative indefinites, comparative quantifiers, and numerals. There are two main observations that justify this approach. First, split scope shows the same kinds of restrictions across these different quantifiers. Second, split scope always involves low existential force. In our approach, following Sauerland, natural language determiner quantifiers are quantifiers over choice functions, of type <<,t>,t>. In split readings, the quantifier over choice functions scopes above other (...) operators (such as intensional verbs like must or can). Determiner quantifiers leave a choice-function trace when they move and this trace combines with the noun restriction, which is interpreted low. That split scope always involves low existential force is derived, without stipulation, from Kratzer’s idea that low existential force can be achieved via binding (into the noun restriction).

This paper discusses Aristotle's notion of the practical syllogism. It is argued that the notion of ‘practical’ reasoning in the sense of reasoning which implies motion in one sense or the other is alien to Aristotle's philosophy of nature. All (at least in type) the relevant passages will be discussed. The outcome is that there are three different contexts in which it would be justified to speak of practical syllogisms: (i) human deliberation, (ii) the illustration of the triggering cause of (...) animal motion, and (iii) the teleological ex post explanationof human action. (i) is genuine, but non-deductive reasoning which does not immediately result in action/motion, whereas (ii) is not genuine reasoning, but an analogy with deductive reasoning. Finally, the relation between (i) and (ii) in Aristotle's theory of animal motion will be discussed. (shrink)

The aim of this chapter is to explain Aristotle’s definition of the vegetative part of the soul in the De anima from a methodological point of view. I discuss Aristotle’s conception of the soul and his conception of “parts of the soul” before I turn to his definition of the vegetative part of the soul in De anima II 4. I argue that the definition of the vegetative capacity is deliberately abstract so as to cover its various activities under one (...) common heading. I also argue that the De anima deliberately avoids a positive and determinate description of the activity of the soul that is properly responsible for the vegetative functions, and that Aristotle offers such a positive and determinate description in his works dedicated to the actions and affections “common to body and soul”.

Images are objects of work in the laboratory. On its face, this work is achieved through talk Yet the talk attached to these images makes reference to other images, which are drawn from varcous environments. In this article, four such environments are identified: the domain of laboratory practice; the context of invisible physical reactions; the future image as it will appear in publication; and the domain of case precedents and reference scenarios from the field. The work of image analysis brings (...) the outside of the image into it and takes the inside out. Thus it can be seen that images are not just taken, they are designed and made. (shrink)

How do animals make themselves move? Unlike most modern theories, Aristotle answers this question through a general theory of animal movement valid for both humans and animals. This book interprets this theory and analyses its fundamental concepts.

Plato's depiction of the world soul's cognitive activity in Timaeus 37 A 2‐C 5 offers a general account of intellectual cognition. He gives this account by describing the activity of an ideal cognitive agent, involving the very same comparative mechanism that governs human intellectual activity, namely, the active production of a propositional grasp of sameness and difference that things have in relation to each other in several respects. Plato depicts the world soul's intellectual activity as entirely devoid of immediate forms (...) of cognition such as perception and/or intellectual intuition: everything the world soul cognizes is the outcome of its active comparison of things with each other. In particular, there is no direct cognitive grasp of the being of things. The paper ends with a suggestion as to how to understand Plato's account of the world soul's activity as an instance of the ‘like is known by like’ principle of cognition. (shrink)

Among scholars it is common to assume that Aristotle’s practical syllogism does two jobs. It is often taken to explain both animal motion and human deliberation. I will call this the “two-jobs view of the practical syllogism”. In what follows, I will argue that the two-jobs view of the practical syllogism is not working. I will then try to give a very brief and incomplete sketch of how to conceive of a non-two-jobs view of the Aristotelian practical syllogism. Finally, I (...) will discuss two possible problems for the non-two-jobs view. (shrink)

A definition of emotion common to the affective sciences is an urgent desideratum. Lack of such a definition is a constant source of numerous misunderstandings and a series of mostly fruitless debates. There is little hope that there ever will be agreement on a common definition of emotion, given the sacred traditions of the disciplines involved and the egos of the scholars working in these disciplines. Our aim here is more modest. We propose a list of elements for a working (...) definition of emotion and discuss the justification for the inclusion of elements from our respective perspectives (philosophy and psychology). This working partial definition may at least serve as a litmus test to examine theories of emotion, old and new, across disciplinary boundaries. (shrink)

Zusammenfassung Der Beitrag untersucht den Gebrauch von Moral in der Kommunikation zwischen Trainer und Ath­leten im Spitzensport. Dabei wird moralische Kommunikation aus systemtheoretischer Perspektive als soziale Tatsache konstruiert, um im Lichte dieser Konstruktion konkrete Beispiele aus den Sport­arten Handball und Hockey analysieren und im Hinblick auf ihre Funktionen und Folgen reflektie­ren zu können. Die Ergebnisse dieser Analysen münden in Empfehlungen an Trainer, die zu einem sensiblen Umgang mit Moral raten, da insbesondere dem polemogenen Charakter moralischer und moralisierender Kommunikation Rechnung zu (...) tragen ist.
