Pensare in maniera inventiva. Saggio introduttivo a Ottica e Pittura di H. von Helmholtz
2023
Il saggio ricostruisce il contesto filosofico e scientifico in cui von Helmholtz perviene all’idea che la ricerca in arte, filosofia e scienza comporti benefici reciproci. Si espone la teoria della percezione che von Helmholtz consolida per fornire una giustificazione epistemologica ai risultati della ricerca scientifica sulla percezione visiva e sonora, in cui ottica, psicologia e fisiologia ne definiscono i livelli di analisi. Si illustrano sistematicamente i problemi di percezione delle forme, della profondità, della luce e del colore rilevanti per la visione e la pittura, rendendo esplicito il collegamento tra la ricerca sperimentale di von Helmholtz, quella di Newton, Wollastone, Wheat…
Experimental Phenomenology in Contemporary pPerception Sciences
2008
A formal role is deemed for experimental phenomenology to be played for a common interdisciplinary framework in perception science to obtain. An systematic account of experimental results on the phenomenology of visual perception and their formalisation in terms of manifold relations is provided. A model for interdisciplinary reserach is suggested with phenomenological explanationa self-closedness traded off against inter-domain research.
Pensieri sull'educazione artistica
2021
In his Thoughts on Art Education, Arnheim describes the perceptual, cognitive and affective components underlying art production and enjoyment. He contends that those components dictate the lines along which educational and teaching plans are to be designed. Since the components underlying art involve the workings of mind as a whole and art is an outstanding instance of the class of structural problems, which arise in many fields, such plans may be intended as curricula that cut across many disciplines. Therefore, Art education gives a meaningful contribution to personality development. This new edition of Arnheim's work the result of an entirely new translation and is characterized by a cr…
Eidetics
2020
The term eidetics denotes the domain of eidetic imagery and its study. The standard phenomenon of eidetic imagery consists in seeing a stimulus that is no longer present, when the experimenter is allowed to infer from subjects’ reports or experimental protocols that “seeing” is different from remembering or experiencing an after-image. After a prolonged period from mid-1930 to about 1960 in which the interest in this phenomenon had died out, research was resumed on the grounds of findings which seemed to point at the ability of extracting information from no longer present stimuli, which showed to be different from sensory and recognition memory. The functional role of eidetic imagery in co…
Line
2020
In the Elements of Geometry, Euclid defines the line as “a length without breadth,” an element without width and depth. The concept of line occurs in propositions, both theorems and proofs, given the postulates that it is possible to draw a straight line between any two points and to extend continuously any line. In Euclid’s Optics, lines are the subject of theorems. Rubin studied the perceptual conditions that could have given an intuitive contribution to the definition of geometrical objects that like in Euclid’s geometry do not occur in experience, yet have a relation with visual constructions. Pictures exploit markings endowed with perceptual linearity and continuity which realize lines…
Perception / percept
2020
The term perception denotes the capacity of grasping something that to the common sense belongs to external world, which is the stable and persistent collection of things that are the natural and man-made furniture of the environment. Perception denotes also the capacity of sensing something, like warmth or pain, that is the effect of an external or internal cause localized on or inside one’s own body. Therefore, perception has subjective and objective factors as constituents of its conditions of satisfaction. The activity of perception is describable in terms of the percept, namely the objective constituent of its conditions of satisfaction
Analogy
2020
Analogy is a mode of reasoning that is employed in problem solving, logic, science and art. The scheme of analogical reasoning is centred on the detection of similarity or common features across domains. Copi and Cohen (2005), Keynes (1921), Carnap (1980) suggested what analogical reasoning consists of. De Finetti (1938) proposed an alternative treatment of analogy as inference on what is invariant across statistical distributions of distinct event kinds. In problem solving theory, cognitive models of the content and the structural mapping of analogy has been built. Science and art has provided important test beds for models.
Drawing
2020
A drawing is the result of the production of marks on a surface with suitable means to represent a scene, concrete or abstract objects for technological, scientific, artistic, communicative aims. Some theories claimed that drawing is founded on symbolic systems that are culture-dependent. Evidence has been found that the ability of recognizing what drawings represent is widespread across ages, cultures and species. Drawing may be founded on shared cognitive capacities. These capacities can be abstractly described as the graphic and the denotation system.
QUALI FENOMENI PER L’ESTETICA EMPIRICA?
2020
Empirical Aesthetics profits from the research in Cognitive Neurosciences and the target article collects multiple evidence on the neurobiological basis of art and aesthetic experience in order to submit that psychological models give a new definition of the field of Psychology of Arts, if they integrate this empirical evidence with the perceptual, emotional and cognitive capacities, which are assumed to give rise to art and aesthetic experience. The opinion article raises questions about the variety of phenomena in the field, the common methodology to experimental research on cognition and aesthetics, the manifold perceptual attributes which support art and aesthetic cognition, the potenti…
Visualization/Visibility
2020
The term visualization is employed to refer to the capacity of making visible properties, relations, objects and state of affairs which either are no longer presented through perception or depends upon concepts and theoretical definitions, which regard domains that lie outside the scope of perception. In the strict sense, visualization is the kind of experience akin to perception, which is enabled by the structure and the function of imagery. From a functional standpoint, then, the capacity of visualization relies on a not arbitrary mapping between visual-spatial representations and what they stand for. In this broader sense, it is connected with perception and rule-based qualitative reason…
