In his ecological approach to perception, James Gibson introduced the concept of affordance to refer to the perceived meaning of environmental objects and events. this paper examines the relational and causal character of affordances, as well as the grounds for extending affordances beyond environmental features with transcultural meaning to include those features with culturally-specific meaning. such an extension is seen as warranted once affordances are grounded in an intentional analysis of perception. toward this end, aspects of merleau-ponty's treatment of perception (...) are explored. finally, a resolution of the apparent tension between the relational and perceiver-independent nature of affordances is presented.

The goal of this study is to characterize observers’ abilities to discriminate between endogenous and exogenous changes. To do so, we developed a new experimental paradigm. On each trial, participants were shown a dot pattern on the screen. Next, the pattern disappeared and participants were to reproduce it. Changes were surreptuously introduced in the stimulus, either by presenting participants anew with the dot pattern they had themselves produced on the previous trial or by presenting participants with a slightly different dot (...) pattern . We analyzed awareness of the changes and behavioral adaptation to them in a dynamical manner. We observe signal attenuation in the presence of endogenous change, dissociation between self-attribution reports and behavioral effect of agency. We discuss the source of this sensitive attenuation as well as the relation between a minimal or core self and an extended, narrative or autobiographical self. (shrink)

The endeavor to naturalize the philosophy of biology brings the problem of agency to the forefront, along with renewed attention to the organism and organicism. In this article, we argue for a mutualist approach to agency that starts to unravel layers of this complex issue by focusing on perception and action at the core of all biological agency. The mutuality of animals and their surroundings is seen as distinct from the typical concepts of organism, preexisting environment, and their interactions. Mutuality (...) means a deep ontological and epistemological compatibility between the organism and its surround. We suggest that the concept of direct perception developed and empirically researched in the tradition of the ecological approach, launched by James J. Gibson, offers a promising path to approach agency within an ecological–mutuality framework. At the core of our definition of agency is the animal’s ability to self-initiate actions and activities. Animals are the source of their own actions and activities within the mutual, co-defining relation to their surround. The place of agency related to mutuality has not been elaborated sufficiently thus far, in either biology or ecological psychology. In this article, our goal is to argue for the necessity of placing agency into an ecological–mutuality framework and of further research in this direction in line with Marjorie Grene’s call to assimilate Gibson’s theory of knowledge into biology.

Central to contemporary cognitive science is the notion that mental processes involve computations defined over internal representations. This view stands in sharp contrast to the to visual perception and cognition, whose most prominent proponent has been J.J. Gibson. In the direct theory, perception does not involve computations of any sort; it is the result of the direct pickup of available information. The publication of Gibson's recent book (Gibson 1979) offers an opportunity to examine his approach, and, more generally, to contrast (...) the theory of direct perception with the computational/representational view. In the first part of the present article (Sections 2direct perceptioncase study”: the problem of perceiving the three-dimensional shape of moving objects is examined. This problem, which has been extensively studied within the immediate perception framework, serves to illustrate some of the inherent shortcomings of that approach. Finally, in Section 5, an attempt is made to place the theory of direct perception in perspective by embedding it in a more comprehensive framework. (shrink)

Human performance in natural environments is deeply impressive, and still much beyond current AI. Experimental techniques, such as eye tracking, may be useful to understand the cognitive basis of this performance, and “the human advantage.” Driving is domain where these techniques may deployed, in tasks ranging from rigorously controlled laboratory settings through high-fidelity simulations to naturalistic experiments in the wild. This research has revealed robust patterns that can be reliably identified and replicated in the field and reproduced in the lab. (...) The purpose of this review is to cover the basics of what is known about these gaze behaviors, and some of their implications for understanding visually guided steering. The phenomena reviewed will be of interest to those working on any domain where visual guidance and control with similar task demands is involved. The paper is intended to be accessible to the non-specialist, without oversimplifying the complexity of real-world visual behavior. The literature reviewed will provide an information base useful for researchers working on oculomotor behaviors and physiology in the lab who wish to extend their research into more naturalistic locomotor tasks, or researchers in more applied fields who wish to bring aspects of the real-world ecology under experimental scrutiny. Part of a Research Topic on Gaze Strategies in Closed Self-paced tasks, this aspect of the driving task is discussed. It is in particular emphasized why it is important to carefully separate the visual strategies driving from visual behaviors relevant to other forms of driver behavior. There is always a balance to strike between ecological complexity and experimental control. One way to reconcile these demands is to look for natural, real-world tasks and behavior that are rich enough to be interesting yet sufficiently constrained and well-understood to be replicated in simulators and the lab. This ecological approach to driving as a model behavior and the way the connection between “lab” and “real world” can be spanned in this research is of interest to anyone keen to develop more ecologically representative designs for studying human gaze behavior.

Theorizing about perception is often motivated by a belief that without a way of ensuring that our perceptual experience correctly reflects the external world we cannot be sure that we perceive the world at all. Historically, coming up with a way of securing such epistemic contact has been a foundational issue in psychology. Recent ecological and enactive approaches challenge the requirement for perception to attain epistemic contact. This article aims to explicate this pragmatic starting point and the new direction of (...) inquiry that this opens up for psychology. It does so by detailing the development of James J. Gibson’s ecological psychology. Securing epistemic contact has been a leitmotiv in Gibson’s early work, but subsequent developments in Gibson’s works can teach us what it takes to adopt a pragmatic approach to psychology. We propose a reading of the developments in Gibson’s original works that shows that, since perception is a mode of acting, perception aims for pragmatic contact before allowing for epistemic contact. Amplifying these pragmatist lines of thought in Gibson’s works we end by considering situations where an individual is adapted to the intricacies of specific social practices. These situations show how pragmatic contact can also afford attaining epistemic contact. (shrink)
