Appunti per lo studio psicologico del tempo: dal dogma dell’istantaneità al tempo di compresenza
No full textNewPerceptual Organization within Temporal Displacement
No full textThe psychological present has an actual extension.
When a sequence of instantaneous stimuli falls in this short interval
of time, observers perceive a compresence of events in succession
and the temporal order depends on the qualitative relationships
between the perceptual properties of the events. Two experiments
were carried out to study the influence of perceptual grouping, with
and without temporal displacement, on the duration of auditory
sequences. The psychophysical method of adjustment was adopted.
The first experiment investigated the effect of temporal displacement
of a white noise on sequence duration. The second experiment
investigated the effect of temporal displacement, along the pitch
dimension, on temporal shortening of sequence. The results suggest
that the temporal order of sounds, in the case of temporal
displacement, is organized along the pitch dimension
The effect of symmetry on the perception of happiness and boredom in design products
No full textThe present research investigates the effect of symmetry on the perception of happiness and boredom in design products. Three experiments were carried out in order to verify the degree of the visual expressive value on different models of bookcases, wall clocks, and chairs. 60 participants directly indicated the degree of happiness and boredom using 7-point rating scales. The findings show that the participants acknowledged a different value of expressive quality in the different product models. Results show also that symmetry is not a significant constraint for an emotional design project
Why experimentum crucis is possible in psychology of perception
No full texthis paper examines the experimentum crucis under the light of the Duhem’s holistic thesis. This methodological instrument is not usable in physics, because physical theories are always logically connected to many assumptions. On the contrary, it is usable in psychological research oriented to perceptual laws, when these laws are, without any hy- pothetical term, isolated systems. An application of experimentum crucis in Experimental Phenomenology of perception is presented. In conclusion, the role of perceptual knowl- edge as an essential assumption in other scientific disciplines that have a high degree of theoricity is also underlined
Scientific Phenomenology in Design Pedagogy : The Legacy of Walter Gropius and Gestalt Psychology
No full textThis article examines the contribution of scientific phenomenology in design pedagogy through the theoretical relationships between the German art school Staatliches Bauhaus and the most important scientific phenomenological theories of the first half of the twentieth century. After showing the relationships between the Gestalt Theory and the principal teachers of the Bauhaus (Johannes Itten, Paul Klee, Wassily Kandinsky, László Moholy-Nagy, Josef Albers), the pedagogical epistemology of Walter Gropius is critically presented. The epoché, the intersubjective criterion and the anti-psychologism are examined. In conclusion, it is evidenced that Gropius was strongly influenced by Gestalt psychology. This undeclared influence was a necessary consequence of the fact that phenomenological attitude is a crucial operating modality for the concrete practice of design
Influence of bichord interval on perception of simultaneity
No full textThe present paper investigates the influence of the bichord interval between two pure-tones on perceptual simultaneity. In the experiment, 30 participants (musicians and non musicians) listened to tone pairs (bichords: C-D; C-E flat; C-F sharp; C-G) with different degrees of asynchronization and indicated whether two tones had been simultaneous or successive. The method of constant stimuli was used. An ANOVA showed that bichords intervals were perceived with different degrees of simultaneity (p< 0.0001). Tones that are less distant in frequency are not necessarily easier to perceive as simultaneous. This result suggests that judgement of simultaneity cannot be accounted for only in terms of frequency or temporal relationship between single stimuli at the physical level. The effect of a non temporal variable concerning the perceptual moment hypothesis is discussed
Perceived security: An experimental study of security doors
No full textThe feeling of security of your own home is given both by the minimization of the real risk of infringement and by the conditions for minimizing the psychological threats experienced by the user.
This study investigates the impact of visual design factors on perceived security of security doors. Experiment 1 verified the effect of different security door models on perceived security. For each model, participants indi- cated the perceived security on a 7-point rating scale. In the second experiment, 308 naïve participants estimated the perceived security of the security doors with ten morphological modifications (asymmetry; curved edges; reduced colorfulness; rhomboid panels; relief mullions; nails; engraved texture; electronic lock; double lock; bronze door handle). The influence of visual design factors on perceived security was confirmed in experiment 1. The results also show that asymmetry, nails doors and electronic lock increase perceived security significantly. Finally, the findings in relation to the design of security door are discussed
Experimental Phenomenology, a rhapsody
No full textExperimental Phenomenology can boast an ample repertoire of discoveries, that is facts which not only represent a foundation of incontrovertible empirical knowledge,
but also the explanandum on which other scientific disciplines can model new hypotheses in the abstract. Nevertheless, there is still an ambivalent attitude both of deference and diffidence towards Experimental Phenomenology. This attitude is the consequence of at least two factors: on
the one hand a mixture of prejudices and misunderstandings and, on the other, a failing of the discipline itself: the lack of a theory
A Study of Objects With Smooth or Sharp Features Created as Line Drawings by Individuals Trained in Design
No full textThere is a long history of studies of shape preference using simple abstract two-dimensional shapes. The evidence has confirmed a preference for symmetry, high contrast, and smoothness over asymmetry, low contrast, and angularity. However, the evidence about the role of culture and expertise is inconclusive. We asked a group of 56 expert designers (studying at the IUAV) to draw seven objects on paper and for each provide two versions: a smooth version and an angular version. These stimuli therefore show everyday objects, freely chosen by the authors, drawn with novel shapes. Next, we presented these stimuli to nonexperts. We collected ratings for seven characteristics (“ugly/beautiful, dark/light, complex/simple, heavy/light, old/modern, dangerous/safe, and asymmetrical/symmetrical”) from naive observers (n = 174). The analysis of the rating data confirmed a link between smoothness and beauty as well as a few other associations. We made the database (772 images) including the average ratings openly available to other researchers
