Neste texto, discuto a interpretação defendida por Moyal-Sharrock, segundo a qual as proposições eixo são maneiras de agir com o objetivo de oferecer uma proposta sobre como compreendê-las. Sustento que a posição de Moyal-Sharrock deixa algumas lacunas, porque não explica a origem das nossas certezas fundamentais. A sua leitura também carece de recursos para responder ao problema da demarcação, uma vez que não é claro como distinguir maneiras de agir que podem legitimamente cumprir o papel de fundamento não fundamentado das que não podem. Sem uma resposta para esse problema, a ameaça relativista é séria. Proponho, então, que as proposições eixo são maneiras de agir constitutivas de habilidades. Desenvolvo também uma abordagem ecológica das habilidades, a qual me possibilita explicar por que habilidades são embebidas-de-realidade e, por conseguinte, por que as maneiras de agir que as constituem são fundamentos não fundamentados legítimos. Com base nessa abordagem, ofereço uma resposta para o problema da demarcação que afasta a ameaça relativista.
A short entry on Social Affordances. Social affordances are possibilities for social interaction or possibilities for action that are shaped by social practices and norms.
Giovanni Rolla and I have just published a paper in Frontiers Psychology: An Enactive-Ecological Approach to Information and Uncertainty #openaccess Available here and here.
Information is a central notion for cognitive sciences and neurosciences, but there is no agreement on what it means for a cognitive system to acquire information about its surroundings. In this paper, we approximate three influential views on information: the one at play in ecological psychology, which is sometimes called information for action; the notion of information as covariance as developed by some enactivists, and the idea of information as minimization of uncertainty as presented by Shannon. Our main thesis is that information for action can be construed as covariant information, and that learning to perceive covariant information is a matter of minimizing uncertainty through skilled performance. We argue that the agent’s cognitive system conveys information for acting in an environment by minimizing uncertainty about how to achieve her intended goals in that environment. We conclude by reviewing empirical findings that support our view and by showing how direct learning, seen as instance of ecological rationality at work, is how mere possibilities for action are turned into embodied know-how. Finally, we indicate the affinity between direct learning and sense-making activity.
In this paper I claim that perceptual discriminatory skills rely on a suitable type of environment as an enabling condition for their exercise. This is because of the constitutive connection between environment and perceptual discriminatory skills, inasmuch as such connection is construed from an ecological approach. The exercise of a discriminatory skill yields knowledge of affordances of objects, properties, or events in the surrounding environment. This is practical knowledge in the first-person perspective. An organism learns to perceive an object by becoming sensitized to its affordances. I call this position ecological disjunctivism. A corollary of this position is that a case of perception and its corresponding case of hallucination—which is similar to the former only in some respects—are different in nature. I show then how the distinguishability problem is addressed by ecological disjunctivism.
Neste capítulo, apresento e sustento uma articulação da noção de habilidade corporal ou sensoriomotora a partir da psicologia ecológica e mostro como ela é relevante para o debate entre Dreyfus e McDowell sobre a lida habilidosa e também para o debate sobre se saber-fazer se reduz ou não a conhecimento proposicional. A metáfora correta para compreender habilidades corporais não é a do computador, mas a do rádio. Essas habilidades resultam de um processo de sintonização do organismo com o seu ambiente.
The extended mind thesis claims that at least some cognitive processes extend beyond the organism’s brain in that they are constituted by the organism’s actions on its surrounding environment. A more radical move would be to claim that social actions performed by the organism could at least constitute some of its mental processes. This can be called the socially extended mind thesis. Based on the notion of affordance as developed in the ecological psychology tradition, I defend the view that perception extends to the environment. Then I will expand the notion of affordance to encompass social affordances. Thus, perception can in some situations also be socially extended.
