Flavour: From food to perception
2016
Revue; This book will cover all aspects of flavour perception, including aroma, taste and the role of the trigeminal nerve, from the general composition of food to the perception at the peri-receptor and central level. This book will answer to a growing need for multidisciplinary approaches to better understand the mechanisms involved in flavour perception.The book presents the bases of anatomy of sensory perception. It will provide the requisite basic knowledge on the molecules responsible for flavour perception, on their release from the food matrix during the eating process in order to reach the chemosensory receptors, and on their retention and release from and transformation by bodily …
Introduction: The World as a Stereogram
2014
This paper presents the historically most important theories of how visual perception is made spatial in the cognitive processing of the sensory input to the eye. All of them involve active engagement of the mind. Firstly, in the medieval theories physiological processes developed three-dimensional imagery in the brain, and active mental processing was needed to build coherence in the perceptual experience as a whole but not to yield the basic idea of spatiality. Secondly, according to Descartes, the eyes produced a unified two-dimensional visual image that was neurally transmitted to the inner surface of the brain. The innate conception of three-dimensional spatiality was superimposed inte…
Whatever next? Predictive brains, situated agents, and the future of cognitive science
2012
In the target article, Andy Clark addresses the question of how a probabilistic predictive coding model of the mind relates to our personal level mental lives. This question, he suggests, is “potentially the most important” (MS46). The question is important indeed, but Clark’s answer fails to capitalize on another possible advantage of this approach. Clark suggests that there is a disconnect between the way the world appears to us, on one hand, and the way that it is represented in the brain, on the other. He deals with this disconnect by limiting the scope of the theory, by pointing out that he is discussing a theory of how brains encode and process information, not a theory about how thin…
Perceptual semantics: A three-level approach
2010
In this work we suggest a model according to which semantics has been already generated during the perception through the interaction of three dynamic levels of perceptual organization. We consider perceptual grouping as the first order processing. Shape formation is considered as the second order processing. Both grouping and shape formation can be considered as two complementary and interrelated processes of perceptual organization. The third — partially overlapping — level is meaning assignment. Most of the results are supported by empirical evidence based on new visual illusions of shape and meaning and are consistent with several other proposals (e.g., [1], [2] and [3]).
In Defense of Position Uncertainty
2015
The authors comments on the article "Orthographic coding in illiterates," by J. A. Dunabeitia, et al. There is a high degree of flexibility in letter-position coding during visual word recognition and reading. This phenomenon is explained based on the presence of perceptual noise in the information used for locating the positions of objects, namely, letters, across space.

Seeking for the Grasp : An Iterative Subdivision Model of Conceptualisation
2019
Concepts are fundamental collective constructs of individual items that are capable of abstracting meaningfully homogeneous groupings of phenomena. This capability is a prerequisite for communication and action and gives structure to learning and memory. Our study is aligned with the vast paradigm that assumes embodied cognition, rooted in Merleau-Ponty (Phenomenology of perception (trans: C. Smith). Routledge and Kegan Paul, London, 1962), seminally articulated by Varela et al. (Embodied mind: cognitive science and human experience. MIT Press, Cambridge, MA, 1991) and existing today in a number of variants that have been reviewed by Wilson (Six views of embodied cognition. Springer. Psycho…
Subliminal Perception, Microgenesis, and Personality
1986
Publisher Summary In person perception, the interpersonal dimension is useful, as is implicated in communicating personal contents. The problem of consciousness is intimately connected with that of knowledge based on subjective experience and perception by means of which it is mediated. This chapter presents the theories that incorporate the subject–object relationships into a comprehensive observational framework. They also emphasize the coherence of subject and environment. The perceiver is viewed as an active subject; the rhythmic properties of all living phenomena are highlighted. The long-term effect of “selective visual exposure” in the early stages of development upon functional cell…
Investigating metaphors of musical involvement : Immersion, flow, interaction and incorporation
2018
The concept of immersion, despite being relatively unknown within music research, presents a potentially productive way for understanding the well acknowledged phenomenon of "being drawn into music". This paper 1) discusses immersion as a metaphor for conceptualizing musical involvement by drawing on the research into video games and virtual reality and 2) aims to clarify the metaphor of immersion by utilizing the concept of image schema to analyze it in relation to alternative metaphors of flow, interaction and incorporation. The theoretical stance of the paper is based on the paradigm of enactive cognitive sciences, which stresses the bodily, constructive and interactive nature of experie…
Brain Biophysics: Perception, Consciousness, Creativity. Brain Computer Interface (BCI)
2018
The paper presents connections between perception, awareness, and creativity from the biophysical point of view. Attention was drawn to human senses’ limitations and their influence on cognition. The role of interfaces connecting brain with computer and particular role of Brain Computer Interface (BCI) are indicated which the authors believe will be the next stage of human brain supporting technology evolution. It will enable the growth of perception, awareness, and creativity, and consequently lead to social development.
