Psicologia della percezione
No full textLa capacità di percepire gli oggetti presenti nel nostro campo visivo è immediata e automatica. E’ talmente efficiente che, in genere, non ci poniamo domande sul suo funzionamento. Ci interroghiamo soltanto quando la percezione ci inganna, quando, per esempio, notiamo con sorpresa che non è il nostro treno a muoversi, ma quello sul binario a fianco, o la luna, che ci appare grande all’orizzonte, è la stessa che vediamo più piccola in alto nel cielo.,
Questo libro racconta il funzionamento della percezione. All’inizio si parla di sensazione, si continua con gli organi di senso, occhio e orecchio, per arrivare ai meccanismi dell’attenzione. Una parte è dedicata alle principali teorie della visione e ai fenomeni percettivi, con riferimenti pittorici e musicali. Infine, con un approccio più applicativo, sono trattati argomenti relativi alla comunicazione visiva e alla fruizione di immagini d’arte
Aesthetic evaluation of design objects at an implicit and explicit level between laypeople and experts
No full textCan the preference for industrial design objects be also achieved automatically? The aim of the study is to verify if different levels of expertise on industrial design (laypeople vs. design students) can orient the preference towards different styles of design objects (classic objects vs. modern objects), at an implicit and explicit level. Implicit and explicit preferences are often mediated by assessor features.
The Implicit Association Test (IAT; Greenwald, McGhee & Schwartz, 1998) was used to assess the automaticity of the evaluation. Participants (44 laypeople and 40 design students) performed a categorization task of pictures (5 classic and 5 modern chairs) and words (5 positive and 5 negative aesthetic words). Reaction times were registered.
The explicit evaluation of the stimuli was assess through a 7 points Likert scale for the adjectives beautiful, typical, familiar, complex and interesting.
In both measurements, implicit and explicit preferences for classic and modern objects were moderate by expertise: experts were more aesthetically oriented towards modern objects while laypeople towards classical ones. According to the model of Processing Fluency (Reber, Schwarz e Winkielman, 2004) the more one is fluent in the processing of an object, the more positive the aesthetic evaluation will be
Percezione dell'ambiente e disegno: un approccio integrato di analisi delle forme e dei contenuti
No full textTiles are not just for floors
No full textThe aim of the paper is to describe Sergio Lombardo’s artworks called “Tiles” in term of perceptual analysis: from the figure/ground articulation as one of the most basic principle of organization of our perceptual field to the different types of symmetry used for the tessellations of a flat surface
The perception of space and the illusion of perspective
No full textThis paper deals with some aspects related to the perception of space and the most important indexes of the perception of three-dimensionality. Physiological indexes (such as accomodation, convergence, and binocular disparity), and pictorial indexes (such as texture density gradients, occlusion, etc.) are reported. The interest will be focused on the representation of space in two-dimensional surfaces, with particular attention towards the linear perspective. The discover of linear perspective in western art, in the 1400’s, opened up an important field of artistic research. The representation of the three-dimensional world on a flat two-dimensional surface has been one of the most challenging aspects of the visual art for several centuries. The importance of linear perspective will be discussed also with respect to the interpretation of various visual illusions
