Giulia Parovel, Effetti comici della causalità percettiva
Full text linkMentre le illusioni ottico-geometriche sono diffusamente note, lo sono molto meno altri fenomeni di organizzazione percettiva dotati di qualità più sottili e in un certo senso apparentemente "morfo-cognitive" delle semplici, anche se sorprendenti, variazioni apparenti di lunghezza, grandezza,
forma o chiarezza che ritroviamo nelle classiche illusioni. Mi riferisco infatti alle dimostrazioni sulla sensatezza e percepibilità - non inferita ma diretta, incontrata - di fenomeni quali
la causalità fenomenica, meccanica o psicologica, l'animacy, per considerare alcune ricerche sperimentali svolte da me e Stefano Guidi sulla risposta emozionale che la presenza o meglio la compresenza contraddittoria di questi ingredienti percettivi può sorprendentemente generare (PAROVEL & GUIDI 2015)
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Funes, o l'arte della percezione
No full textSaggio teoretico ispirato al racconto "Funes, o della memoria", di J. L. Borges, pubblicato nell'antologia Finzioni (1944). Il saggio è scritto sotto forma di racconto, e si concentra sul rapporto tra percezione visiva, intesa come esperienza fenomenica del mondo, e processi di pensiero e categorizzazione. E' un invito a concepire la percezione visiva come una forma di conoscenza le cui potenzialità sono spesso inosservate, e l'arte come uno strumento empirico funzionale ad accedere ed ampliare l'esperienza percettiva
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Percezione visiva, comunicazione, design
No full textOgni giorno percepiamo tante cose che non hanno una corrispondenza nella realtà fisica: come la linea dell’orizzonte tra cielo e mare, o la magia di un arcobaleno. Sentiamo però dire spesso che i sensi sono fallaci, a differenza degli strumenti fisici e matematici, e ammonire a diffidare di ciò che vediamo. Ma possiamo davvero affermare che il nostro sistema percettivo sbaglia? E se fosse invece la nostra aspettativa gnoseologica a essere mal riposta, o il nostro giudizio a ingannarci, anziché i sensi? Se, cambiando prospettiva, concedessimo ai fatti osservabili il diritto di essere propriamente e semplicemente ciò che sono: fenomeni, apparenze, modi di essere? Fatti da osservare e poi eventualmente riportare con carta e matita o in laboratorio per comprendere le leggi e la logica che li descrivono. Fatti interosservabili e investigabili empiricamente con i metodi della psicofisica classica, come le illusioni ottico-geometriche, la profondità pittorica, le illusioni di movimento, le qualità espressive
Paolo Bozzi's Experimental Phenomenology
Full text linkReview of the book Paolo Bozzi ́s Experimental Phenomenology, ed. by Ivana Bianchi & Richard Davies (2018), London: Routledge, 430 Pages. Paolo Bozzi (1930–2003), an Italian experimental psychologist and philosopher, was one of the most brilliant exponents of experimental phenomenology. His scientific and theoretical contributions to vision sciences, cognitive psychology and philosophy of perception are original and wide ranging. Moreover, his reflections and experimental findings are well expressed in an accessible and inspiring style, and can be attractive not only for academic readership but also for a wider one. Prior to this anthology, the majority of Paolo Bozzi’s publications (about 100 articles, book chapters and monographs) had not been translated into English, except for a few papers, and he is still not as well-known internationally as he should be, except to the scholars who have met and appreciated him. This edited volume, conceived by Ivana Bianchi (University of Macerata, Italy) and Richard Davies (University of Bergamo, Italy), is therefore welcome, as it translates and introduces part of the work of Paolo Bozzi to a wider world
Dynamics and expression in visual perception and art: emotions as relational structures
No full textFrom a phenomenological perspective, the entire observable world is a bearer of feelings, as in the case of a cheerful morning or a sullen sky. The issue of expressive qualities offers the possibility of considering emotions and feelings not only as events internal to the subjective sphere, as is implicit in traditional psychology, but also as ‘perceptual structures’ that can take place across the relationship between the observer and the observed.
This chapter aims to provide an organic overview of the main empirical findings in visual perception research in the area of expressive qualities. The focus is on the concept of 'relationship', which is presented as an organising tool capable of encompassing a variety of phenomena in a unified perspective. Indeed, the expressive relationships can be observed in a wide range of manifestations, in both static and dynamic scenarios. They are, for example, the relationship of an object to its environmental reference system (e.g., in the cases of obliquity and gravitational force, or self-propelled motion), the internal articulation of an object (e.g., as in different lines, shapes and trajectories), the relationship between two or more objects (e.g., the principle of ‘faceness’ and dynamic displays such as biological, causal, or intentional patterns), and the whole pattern of relations between various objects (e.g., the ‘atmospheres’). Furthermore, the same relationship between the observer and the observed can vary both on the side of the observed, who can exhibit different degrees of ‘demanding character’, and on the side of the observer, who can adopt different modes of perception, such as a ‘physiognomic’ or a ‘geometric-technical’ mode. In conclusion, the recognition of the role of relations as meaningful perceptual constraints has the important advantage that many expressive events can be operationalised and investigated using the classical methods of experimental psychophysics and experimental phenomenology - by systematically isolating and manipulating the variables involved. The growing body of work in visual aesthetics and in the topic of animacy and social perception reported here suggests that the study of expressiveness deserves a relevant place in experimental psychology alongside other more traditional areas of visual perception research
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
