Quanto grande è la mia testa? Contributi dalla fenomenologia sperimentale della percezione
No full textContrary to what happens as regards most of our body, visual perception of one’s head is possible only through the use of means such as mirrors, pictures, or videos.... In this paper a series of experiments investigating people’s naive perception of their head size is presented. Different conditions manipulating the absence or presence of direct visual information were studied. The results show that the perceived size of one’s head (in the absence of any direct visual information) is not dependent on the image we see when looking in a mirror. In the last part of the paper, the investigation is extended to a sample of self-portait
SULLE FORME MINIME DELL’ESPERIENZA PERCETTIVA: VARIAZIONI E CONTRARIETÀ NEL GANZFELD
No full textThe paper suggests a new view on the classical work by W. Metzger (1930), Optische Untersuchungen am Ganzfeld, that first experimentally investigated the perceptual experience for an observer in a homogeneous field of stimulation (Gan-zfeld). The work is generally discussed for its implications in space perception theories. In the present paper, the reports referred by Metzger are approached from a different perspective, i.e. looking at their contribution in answering a fundamen-tal question about the minimum perceptual organization: is it possible to defini-tively erase variation and opposition from our perceptual experience? The analysis reveals that variations developed along dimensions of opposition are still present to shape our perceptual experience even when an absolute invariance is reached at the stimulation level
Qualities and the Relationship of Antonomy in WordNet.
Full text linkAntonymy has been described from logical, semantic and linguistic perspectives, but an adequate definition of it has yet to be agreed upon. We will argue that antonymy it is a pervasive cognitive structure which needs a perceptual grounding. In this short paper we will focus on some theoretical assumptions forming the basis of Miller and colleagues’ work on Word-Net, concerning the connections between the organization of adjectives and the structure of the qualities which these adjectives express. This assumption is consistent with the results of some recent studies conducted in the field of Experimental Phenomenology of Perception.
The results of these studies support the hypothesis of the perceptual basis of contrariety and provide insights on the way the structure of perception shapes the organization of language
LA PERCEZIONE DELLA FORMA DEI GESTI IDENTICI E CONTRARI
No full textThe contribution of a perceptual approach to the analyses of identical and op-posite gestures was examined. Two experiments involved children aged 6 to 8 in gesture production tasks. The results revealed that subjects rarely solve the tasks of producing the same gesture and the opposite gesture using their own body as frame of reference (egocentric space). The external reference (exocentric space) and the spatial organization structured by the presence of two observers (relational space) turned out to be the frames of reference most frequently used. These findings sug-gest the inadequacy of the egocentric space to explain subjects’ responses in the imitative task and the influence of the specific spatial gestalt, and provide the first evidence of the perceptual shaping of gestures perceived as the opposite
The spatial path to contrariety.
No full textThe opening of this chapter is dedicated to the contrapposto, regarded as the epitome of the thesis put forward which states that contrariety has an intimate connection with the human embodied perception of space. Without trying to answer questions regarding the causative priority between the perception of space and the perception of contrariety, a theoretical framework is proposed and empirical evidence is provided in support of the theory that there is a complex architecture of bipolar dimensional structures in direct experiences of space. This evidence implies that metrical and topological models of contrariety (which can be analyzed experimentally) may be established to deal directly with the phenomenal experience of space and open a door to a new cognitive theory of contrariety
Contrariety in plane mirror reflections.
No full textIn reflections, identity and contrariety are face to face. In fact, the surface of a mirror creates a special phenomenal space where the joint experience of identity and contrariety is maximally present, although the optical rules which explain the physics of reflections do not acknowledge this fact. The debate on the mirror question (i.e. why a mirror reverses left and right but not up and down) which apparently highlights the inversion produced, has not taken the perceptual exploration of the phenomenon far enough. This chapter offers an experimental framework for an investigation into the two perceptual experiences of identity and contrariety and recognizes their role as basic components of the phenomenal geometry of mirror images
