Where brain, body, and world collide

Embodied perspective-taking enhances interpersonal synchronization: A body-swap study

Humans exhibit a strong tendency to synchronize movements with each other, with visual perspective potentially influencing interpersonal synchronization. By manipulating the visual scenes of participants engaged in a joint finger-tapping task, we examined the effects of 1st person and 2nd person visual perspectives on their coordination dynamics. We hypothesized that perceiving the partner's movements from their 1st person perspective would enhance spontaneous interpersonal synchronization, potentially mediated by the embodiment of the partner's hand. We observed significant differences in attractor dynamics across visual perspectives. Specifically, participants in 1st person coupling were unable to maintain de-coupled trajectories as effectively as in 2nd person coupling. Our findings suggest that visual perspective influences coordination dynamics in dyadic interactions, engaging error-correction mechanisms in individual brains as they integrate the partner's hand into their body representation. Our results have the potential to inform the development of applications for motor training and rehabilitation.

Aesthetics without Objects: Towards a Process-Oriented Aesthetic Perception

In this paper, I suggest an aesthetic model that is consistent with anti-foundational scientific knowledge. How has an aesthetics without foundation to be configured? In contrast to the conventional subject/object model, with idealistic and subjective aesthetics, but also with object-oriented assumptions, I suggest that aesthetics has to be characterized as relational aesthetics in terms of process-oriented perception and that this leads to an Aesthetics Without Objects (AWO) approach. The relational nature of processes means that they do not happen inter-, that is, between ontologically delimited and stable entities, but rather they correspond between relations. I will try to show that AWO matches well with the onto-phenomenological-epistemic and relational models proposed by recent theories in different fields of science, especially in the relational interpretation of quantum physics. The field of aesthetics, then, does not indicate perceptual fixed contents—either subjective or objectual properties—rather it emerges from a correspondence occurring in an engaged and situated perceptual movement, an agencing that is prior to any sharp distinction between a perceiver and a perceived. I propose to call haptic this perceptual agencing. In the first section, I describe the reasons according to which the adoption of AWO seems more correct and advisable, both with respect to contemporary scientific models and to the current ecological changes on the planet. In the second section, I portray some characteristics of AWO. In the third section, I argue that AWO calls for haptic perception. In the fourth section, I briefly draw some meta-aesthetics consequences concerning, on the one side, socio-political issues of AWO and, on the other side, the possibility for a theory in an anti-foundational model. I conclude with a proposal: a process-oriented aesthetics approach has to be understood mainly as an art of thinking. This means rethinking and re-evaluating the idea of aesthetics as an artisan thought.

What is driving consumer food waste: Socio-material assemblages of household consumption practices

This paper challenges conventional understandings of how we think about consumer food waste by investigating the food purchasing/wasting views and practices of 102 Colorado (USA) residents (67 households). The methods used in this study included the triangulation of surveys, self-reported pictures of food waste and related daily reports over a two-week period, and focus groups. Understanding who is, and what are, driving food waste is important if the aim is to create policy interventions that meaningfully mitigate loss. This paper approaches concepts like consumer sovereignty and agency through a non-essentialist lens, which is to say it repositions food waste as a mode of ordering as opposed to an outcome of discrete, self-evident products-e.g., attitudes, autonomous consumers. Doing this opens the analysis up to connections that might otherwise go unrecognized when those categories are assumed to be absolute and obvious. After presenting numerical data gleaned from online surveys, findings are organized around the following themes: humans-as-assemblage; storage devices-as-assemblage; and mobility-as-assemblage. The paper concludes synthesizing these themes while suggesting interventions mindful of these fluid socio-material coming-togethers.

Situating Machine Intelligence Within the Cognitive Ecology of the Internet

The Internet is an important focus of attention for the philosophy of mind and cognitive science communities. This is partly because the Internet serves as an important part of the material environment in which a broad array of human cognitive and epistemic activities are situated. The Internet can thus be seen as an important part of the ‘cognitive ecology’ that helps to shape, support and (on occasion) realize aspects of human cognizing. Much of the previous philosophical work in this area has sought to analyze the cognitive significance of the Internet from the perspective of human cognition. There has, as such, been little effort to assess the cognitive significance of the Internet from the perspective of ‘machine cognition’. This is unfortunate, because the Internet is likely to exert a significant influence on the shape of machine intelligence. The present paper attempts to evaluate the extent to which the Internet serves as a form of cognitive ecology for synthetic (machine-based) forms of intelligence. In particular, the phenomenon of Internet-situated machine intelligence is analyzed from the perspective of a number of approaches that are typically subsumed under the heading of situated cognition. These include extended, embedded, scaffolded and embodied approaches to cognition. For each of these approaches, the Internet is shown to be of potential relevance to the development and operation of machine-based cognitive capabilities. Such insights help us to appreciate the role of the Internet in advancing the current state-of-the-art in machine intelligence.

Complexity As Key to Designing Cognitive-Friendly Environments for Older People

The lived environment is the arena where our cognitive skills, preferences, and attitudes come together to determine our ability to interact with the world. The mechanisms through which lived environments can benefit cognitive health in older age are yet to be fully understood. The existing literature suggests that environments which are perceived as stimulating, usable and aesthetically appealing can improve or facilitate cognitive performance both in young and older age. Importantly, optimal stimulation for cognition seems to depend on experiencing sufficiently stimulating environments while not too challenging. Environmental complexity is an important contributor to determining whether an environment provides such an optimal stimulation. The present paper reviews a selection of studies which have explored complexity in relation to perceptual load, environmental preference and perceived usability to propose a framework which explores direct and indirect environmental influences on cognition, and to understand these influences in relation to aging processes. We identify ways to define complexity at different environmental scales, going from micro low-level perceptual features of scenes, to design qualities of proximal environments (e.g., streets, neighborhoods), to broad geographical areas (i.e., natural vs. urban environments). We propose that studying complexity at these different scales will provide new insight into the design of cognitive-friendly environments.

Culture and the Individual

In this paper, I want to suggest a framework for the study of action that does notturn ‘culture’ and ‘psychological phenomena’ into two sides ofa dichotomy, but which is sensitive to the context of action. This is called for in view of what seem to be genuinely interesting developments in our thinking about ourselves: for example,theoretical and empirical attempts to re-unite brain, body, words and world in such a way thatit is no longer interesting to speculate merely about what is ‘in’, and opposed towhat is ‘outside’, the individual. Briefly, I propose a definition of culture thatseems to offer productive empirical possibilities. After this I suggest an empirical focus on task, participant(s) and situation, by way of explicating the resources and constraints operating during action-in-context.

Relating Psychology and Neuroscience: Taking Up the Challenges

Advances in brain research have invigorated an ongoing debate about the relations between psychology and neuroscience. Cognitive science has historically neglected the study of neuroscience, although the influential subfield of cognitive neuroscience has since attempted to combine information processing approaches with an awareness of brain functioning. Although cognitive neuroscience does not necessarily support a reductionist approach, certain philosophers of mind have suggested that psychological constructs will eventually be replaced with descriptions of neurobiological processes. One implicitly popular response to this proposal is that neuroscience represents a level of implementation that is separate from a level of cognition. Although recent work in the philosophy of mind has gone some way to explicating the concept of psychological and neuroscience approaches as different levels, it is suggested here that a tidy framework of levels is somewhat tenuous. A particular challenge comes from the metatheoretical position of embodiment, which places the mind within the body and brain of an active organism which is deeply embedded in the world. In providing an integration of brain, body, mind, and culture, embodiment exemplifies an important line of defense against claims of the possible reduction of psychology by neuroscience.

Dynamical aspects of behavior generation under constraints

Dynamic adaptation is a key feature of brains helping to maintain the quality of their performance in the face of increasingly difficult constraints. How to achieve high-quality performance under demanding real-time conditions is an important question in the study of cognitive behaviors. Animals and humans are embedded in and constrained by their environments. Our goal is to improve the understanding of the dynamics of the interacting brain-environment system by studying human behaviors when completing constrained tasks and by modeling the observed behavior. In this article we present results of experiments with humans performing tasks on the computer under variable time and resource constraints. We compare various models of behavior generation in order to describe the observed human performance. Finally we speculate on mechanisms how chaotic neurodynamics can contribute to the generation of flexible human behaviors under constraints.

Pragmatic ability and disability as emergent phenomena

A holistic approach to pragmatic ability and disability is outlined which takes account both of the behaviour of individuals involved in the communicative process, and also of the underlying factors which contribute to such behaviour. Rather than being seen as resulting directly from a dysfunction in some kind of discrete pragmatic "module" or behavioural mechanism, pragmatic impairment and also normal pragmatic functioning are instead viewed as the emergent consequence of interactions between linguistic, cognitive and sensorimotor processes which take place both within and between individuals.
