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

Full text linkThe 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
Full text linkhis 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
Tertiary-Expressive Qualities for Design
No full textThis chapter deals with tertiary-expressive properties and aims to define, from a Gestalt psychology point of view, the key concepts for design practice.
In the first part of the chapter, a theoretical framework of the tertiary qualities is presented. Starting from Galileo Galilei’s epistemological distinctions between primary and secondary qualities, and the philosophical reflections on the categorization of experienced qualities of Edmund Husserl, I reach the scientific definition of “tertiary qualities” according to Gestalt psychologists. Besides the contributions of Wertheimer, Köhler, and Koffka, Metzger’s theoretical systematization of the “ways of being of qualities” is taken as a major reference, and the conceptual distinction between tertiary qualities, expressive qualities, aufforderungscharakter, and affordances is finally discussed.
The second part of the chapter aims to present the expressive properties in design practice. Two modalities of perceptual communication - the perceptual communication mediated by signs versus the perceptual communication through expressive qualities - are distinguished by means of three antinomies: i) indirect perception versus direct perception, ii) cross reference versus presence, and iii) subjectivity versus universality. Subsequently, it is analyzed how expressiveness is conveyed by single properties (such as shape, size, color, etc.), by objects, and by relationships between objects and their context. In particular, the cases of expressive plurivocal objects (i.e. objects that convey different expressive properties at the same time) are focused. The chapter continues by presenting several design cases with expressive properties in the intermodal and emotional fields, taking as examples both the design of products and communicative artifacts.
In the conclusions, the difference in the use of expressive properties in design and art is discussed
