Attempts to introduce Gestalt theory into the realm of visual neuroscience are discussed on both theoretical and experimental grounds. To define the framework in which these proposals can be defended, this paper outlines the characteristics of a standard model, which qualifies as a received view in the visual neurosciences, and of the research into natural images statistics. The objections to the standard model and the main questions of the natural images research are presented. On these grounds, this paper defends the (...) view that Gestalt psychology and experimental phenomenology provide a contribution to the research into perception by the construction of phenomenological models for an ecologically meaningful interpretation of the empirical evidence and the hypothetical constructs of the natural image research within the visual neuroscience. A formal framework for the phenomenological models is proposed, wherein Gestalt theoretical principles and empirical evidence are represented in terms of topological properties and relationships, which account for the order and structures that make the environment accessible to observers at a relevant behavioural level. It is finally argued that these models allow us to evaluate the principles and the empirical evidence of various natures which are integrated from different fields into the research into perception, and in particular into visual neurosciences.

In past and modern psychophysics there are several unresolved methodological and philosophical problems of human and animal perception, including the outstanding question of the relational basis of whole psychophysics. Here the main issue is discussed: if, and to what extent, there are viable bridges between the traditional “gestalt” oriented approaches and the modern perceptual-cognitive perspectives in psychophysics. Thereby the key concept of psychological “frame of reference” is presented by pointing to Hermann Ebbinghaus' geometric-optical illusions, on the one hand, and Max (...) Wertheimer's treatment of the traditional transposition phenomenon, on the other hand. A much-needed theoretical reorientation of future research may help to overcome the philosophical narrowness of present-day human and comparative psychophysics. (shrink)

Nous reformulons la question du naturalisme sur le terrain de la pratique scientifique en privilégiant une analyse épistémologique fine des méthodes, procédures et concepts employés en psychologie. L’enjeu devient alors opérationnel: celui de la mise en place d’un cadre exact et expérimental permettant de rendre compte de la phénoménologie de l’expérience.

Tertiary qualities have been studied primarily by Gestalt psychologists. My aim in this article is to revisit the theoretical assumptions regarding tertiary qualities. I start from the Galilean distinction of the qualities of experience, the Lockean subdivision of qualities, the subjectivist definition in aesthetics and the theoretical contribution of Gestalt theory, to show the theoretical value of ‘tertiary qualities’ in the current context of experimental psychological research. I conclude that tertiary qualities are a crucial keyword for an experimental psychology based (...) on the primacy of perception. Such a perspective is in favour of a neo-Gestalt Experimental Phenomenology. (shrink)

Cognitive neuroscience has come to be viewed as the flagship of the cognitive sciences and is transforming our understanding of the nature of mind. In this paper we survey several research fields in cognitive neuroscience (lateralization, neuroeconomics, and cognitive control) and note that they are making rapid progress on fundamental issues. Lateralization research is developing a comparative framework for evolutionary analysis, and is identifying individual- and population-level factors that favor brain asymmetries. Neuroeconomics is creating a research framework for studying valuation (...) mechanisms in the brain that allows investigation of more complex phenomena than traditional reward paradigms. And cognitive control research has cast light on the mechanisms of task learning and top-down control that enable fluid goal-directed behavior in complex situations. Reasons for the success of cognitive neuroscience are varied: technical advances (e.g., in molecular genetics and imaging) are part of the story, but the more important factors have to do with the power of integrating a bottom-up mechanistic approach with larger functional and evolutionary perspectives. The incorporation of a bottom-up component differentiates cognitive neuroscience from the multidisciplinary ambitions of classical cognitive science, which suffered from having limited access to mechanisms.

In this theoretical paper, the claim is defended that phenomenology of perception can be integrated into vision science. Different versions of theoretical and experimental phenomenology are presented to specify a minimal set of commitments. It is claimed that the phenomenological research into perception, be it delivered in the form of conceptual analysis or of experimental research, satisfies the epistemological and methodological substantive features of these commitments. As an empirical case for the contribution that the integration of phenomenology into vision science (...) could bring about, the paper presents a received view in the visual neurosciences and the objections against its elementarwise and reductionist stance. The relationships among models and mechanisms are discussed. It is argued that models endowed with linking propositions with phenomenological contents can provide the conceptual case for the integration of phenomenology into vision science to be carried out.
