“…Several of these involve dynamic properties of stimuli which are much easier to appreciate given modern computerised methods for generating visual content. Although many of the new principles can be appreciated by demonstrations, modern vision scientists typically quantify their data using measures of phenomenological psychophysics (Strother, Van Valkenburg, & Kubovy, 2002), which quantify the reported perceptual outcomes, as well as indirect measures which reflect effects of grouping on task performance. For some principles, this has led to a robust understanding of the conditions under which they occur and factors that affect their functioning.…”

Perceptual grouping refers to the process of determining which regions and parts of the visual scene belong together as parts of higher order perceptual units such as objects or patterns. In the early 20 th century, Gestalt psychologists identified a set of classic grouping principles which specified how some image features lead to grouping between elements given that all other factors were held constant. Modern vision scientists have expanded this list to cover a wide range of image features but have also expanded the importance of learning and other non-image factors. Unlike early Gestalt accounts which were based largely on visual demonstrations, modern theories are often explicitly quantitative and involve detailed models of how various image features modulate grouping. Work has also been done to understand the rules by which different grouping principles integrate to form a final percept. This chapter gives an overview of the classic principles, modern developments in understanding them, and new principles and the evidence for them. There is also discussion of some of the larger theoretical issues about grouping such as at what stage of visual processing it occurs and what types of neural mechanisms may implement grouping principles.

“…They were asked to indicate the orientation of the perceived organization by selecting one of four icons on a response screen. In this four-alternative forced-choice (4AFC) task, participants' responses were a, b, c, or d, corresponding to the vectors a, b, c, or d. This method has been called phenomenological psychophysics (Kubovy & Gepshtein, 2003;Strother, Van Valkenburg, & Kubovy, 2003). Unlike traditional psychophysical tasks (i.e., those aimed at establishing detection or discrimination thresholds), the task has no incorrect response.…”

The authors conducted 3 experiments to explore the roles of curvature, density, and relative proximity in the perceptual organization of ambiguous dot patterns. To this end, they developed a new family of regular dot patterns that tend to be perceptually grouped into parallel contours, dot-sampled structured grids (DSGs). DSGs are similar to the dot lattices used to study grouping by proximity, except that only one of the potential organizations is rectilinear; the others are curvilinear. The authors used the method of M. Kubovy and J. Wagemans (1995) to study grouping by proximity in DSGs. They found that in the competition between the most likely organizations, one rectilinear and the other curvilinear, the latter is more salient. This phenomenon cannot be explained by contemporary accounts of grouping by proximity or contour integration.

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. Abstract:We reformulate the issue of naturalism within the realm of scientific practices by suggesting that a fine-grained epistemological analysis of the methods, procedures and concepts of psychology is needed. The outcome of this attempt turns out to be operational as it concerns the construction of an exact and experimental approach that allows one to account for the phenomenology of mental states and processes.
