Summary The paper presents the result of a collective reflection inspired by the individual suggestions of 30 researchers working in different research areas. They are all familiar with the Experimental Phenomenology of Perception, and are aware of the importance that this approach might represent nowadays in their specific research field. The picture that emerges from this ‘mosaic’ stimulates us to consider the potential future developments of this approach if we accept that we need to push its borders beyond the traditional aims of the study of perception (as masterfully developed by the historic Italian Maestri of this approach). If we take this broader view, the Experimental Phenomenology of Perception can extend its perimeters from an analysis of strictly perceptual aspects to an analysis of cognitive and metacognitive aspects (such as aesthetic evaluations, the perception of risk, the experience of certainty/uncertainty in a reasoning process, the perception of proximity to/distance from the solution to a problem and meaning-making in language). The cognitive and metacognitive aspects referred to are grounded in and modelled on the perceiver’s experience of a given situation.

Summary Colour and space are pervasive topics in both perception and art. This article investigates the role of colour and pattern in relation to space and time in the art works by two artists: Frank Stella, a well-known Post-War American abstract painter, and Pieter Vermeersch, an emerging Belgian abstract painter, representing a contemporary trend to break the barriers between artistic disciplines. While Stella adheres to the Modernist logic of non-illusionistic, non-spatial, non-referential art as object, perceived instantaneously, Vermeersch explores ways to enhance the viewers’ spatial and temporal experiences through complex art installations with multiple objects and architectural elements interacting with each other and with the spaces in which they are embedded. We discuss these major themes in some representative art works, and in the way they are perceived and appreciated by contemporary viewers, investigated in four empirical studies: two laboratory experiments using well-controlled stimuli derived from at works, and two museum studies employing a variety of methods, including mobile eye-tracking and questionnaires.

Summary We report an effect of anomalous transparency that is similar to other phantom effects. In an experiment aimed at testing the combined role of (i) motion of the occluding surface and (ii) lightness contrast and polarity on the perception of anomalous transparency, we found that transparency is perceived only with low contrast, and enhanced when the occluding surface is moving. A tentative explanation is suggested, based on simultaneous lightness contrast as a segregation factor and on motion as an integration factor, and discussed in light of previous studies conducted in the theoretical framework of Gestalt theories in perception.

Abstract Prior to the discovery of linear perspective in the fifteenth century, European artists based their compositions more on imagination than the direct observation of nature. Medieval paintings, therefore, can be thought of as ‘mental projections’ of space rather than optical projections, and were sometimes regarded as ‘primitive’ by historians as they lacked the spatial consistency of later works based on the rules of linear perspective. There are noticeable differences in the way objects are depicted in paintings of the different periods. For example, human figures in pre-linear perspective works often vary greatly in size in ways that are not consistent with the laws of optics. Some art historians have attributed this to ‘hierarchical scaling’ in which larger figures have greater narrative significance. But there are examples of paintings that contradict this explanation. In this paper we will consider an alternative to the hierarchical scaling hypothesis: that medieval artists used relative size to elicit empathy and to reflect the perceptual structure of imagination. This hypothesis was first proposed by the art historian Oskar Wulff, but has largely been dismissed since. We argue that artists of this period, far from being naïve, used sophisticated techniques for directing the attention of the viewer to a particular figure in a painting and encouraging them to ‘see’ the depicted space from that figure’s point of view. We offer some experimental evidence in support of this hypothesis and suggest that the way artists have depicted space in paintings has an important bearing on how we imagine and perceive visual space.

Summary Amodal completion involves the impression of existence and properties of visually occluded parts of objects. One aspect of this phenomenon that has been somewhat neglected is the amodal completion of color, which involves the impression that amodally completed surfaces have a particular color. In this paper, this aspect is investigated by constructing a large number of displays with identical target figures embedded in systematically varying contexts, to find out which contexts are conducive for amodal completion of color and which are not. In this setup, the main effects of changes of contexts are changes of geometric and photometric features of junctions along the borders of the target regions, which can cause dramatic differences in the appearance of those regions. Generally, a certain arrangement of T-junctions supports the impression of amodal completion of color, and it can be argued that certain types of X-junctions support a variant of this effect as well.

Summary In the visual arts, the constructions of the spatial and chromatic structures of pictures can hardly be separated from each other. The phenomenological approach from the perspective of the arts provides an independent and worthwhile approach to the topic of colour and space. We address some matters of composition in design and, to some extent, in naturalistic painting. The phenomenological approach from the perspective of the arts reveals various topics that invite further investigation by the means of generic vision science. However, although such studies might lead to increased academic insight, a thorough inquiry by the means of experimental phenomenology might well lead to formal descriptions that come somewhat closer to possible applications in the visual arts.

Abstract In 1993, Agostini and Proffitt showed that perceptual belongingness (the subsumption of some sets of elements into a perceived whole) causes simultaneous lightness contrast to be seen in configurations in which the inducing elements are not adjacent to the target. The aim of the present research was to measure the strength of belongingness in determining the contrast phenomenon when the numbers of the inducing and induced elements and their relative positions are manipulated in Agostini-and-Proffitt-type configurations. In the first experiment, by using a forced choice paradigm, naïve observers indicated which gray disks arranged to form the letter T in two rows (organized with black/white inducers) appeared lighter/darker. In the second experiment, expert observers performed two nulling tasks: 1) the lightness of gray disk(s) was adjusted until it was perceived equal to that of gray target(s) aligned with white/black inducers; 2) the lightness of target(s) organized with white/black inducers was adjusted to match the target(s) organized with black/ white inducers. We found that also when there are few inducers, perceptual belongingness causes the contrast effect to propagate spatially on all the induced elements. Spatial position does not influence the induction effect. Low-level theories cannot account for these phenomena, but higher-level processes must be factored in to explain them.

Abstract We ran a pilot experiment to explore, using a new psychophysical method, the hypothesis proposed by Zietz and Werner in the ’30s, that a sound presented simultaneously with an afterimage can change its phenomenal appearance in non-synaesthetes. The method we adopted is able to directly collect and visualise the apparent changes in intensity of the afterimages, by recording observers’ interactions with a physical feedback mechanism (the paths that the observers generated by moving a cursor), without referring to verbal descriptions. These first findings support some of the most meaningful observations reported by Werner (1934) and Zietz (1931), according to which the colours of the afterimages ‘disintegrate’ at the hearing of a low sound and ‘concentrate’ for a high sound. This relationship is particularly evident with the Yellow stimulus, where the perceived colour intensity of its afterimage seems to have a faster negative change with a low-pitched tone sound, and an increase in intensity and duration when perceived simultaneously with a soprano sound. These data are also coherent with the crossmodal correspondences between both pitch and loudness in audition and lightness and brightness in vision reported in the literature.

Summary This article stages a confrontation between latent nominalist attitudes about inherent expression in perception—physiognomy—and new affective modes. In a classic analysis, Gombrich warned of the lack of veridicality of physiognomic perception, a sentiment endorsed by postmodern theories. At the same time, affect theory affirms a level of directly available intensities. Using the example of Rudolf Arnheim, it can be seen that the two are really specular opposites of each other, each merely valorizing different poles of the affect-cognition scale. Arnheim’s Gestalt theory shows how immediate percepts can have a generic structure, which is differentiated with further acquaintance. Arnheim, however, shows how perception can never account for all the power of expressive seeing. Perception and cognition is always embedded in a social matrix. Using an example of racist antisemitic propaganda used by Gombrich, the political implications of Arnheim’s position are demonstrated.
