Summary Prägnanz was suggested by Max Wertheimer in the 1920s as subsuming all “Laws of Gestalt” as they apply to visual awareness. Thus, it assumes a prominent position in any account of Gestalt phenomena. From a phenomenological perspective, some visual stimuli evidently “have more Prägnanz” than others, so Prägnanz seems to be an intensive quality. Here, we investigate the intricacies that need to be faced on the way to a definition of formal scales. Such measures naturally depend both upon the (...) stimulus and upon the observer. Structural complexity bottlenecks of visual systems play a role, as well as the relevance to biological fitness, that is the affinity to the optical user interface. This positions the notion of Prägnanz squarely within the realm of biology. Indeed, the familiar “releasers” of ethology are singular cases of extremely high Prägnanz. (shrink)

Summary This article questions certain assumptions concerning film form made by the recent psychological film research and compares them to those of precursors of film psychology like Hugo Münsterberg and Rudolf Arnheim, as well as the principles of Gestalt psychology. It is argued that principles of Gestalt psychology such as those of ‘good form’ and good continuation are still underlying the psychological research of film, becoming particularly apparent in its approach to continuity editing. Following an alternative Gestalt genealogy that links (...) Gestalt theory with more recent dynamic models of brain activity and with accounts of brain complexity and neuronal synchronisation, the article concludes that psychological research on film needs to shift the focus from form to transformation, both in conceiving the perceptual and cognitive processing of films and in approaching film aesthetics more broadly.

Summary This article presents the person–environment analysis as a framework for participatory and holistic research. By using common methods of qualitative research and analysis, it is possible to capture the present situation of a person. The person–environment analysis is built on Kurt Lewin’s field theory and a further development of its system of visual representation of the life space. It is argued that the person–environment analysis offers a frame to represent the perceived subjective situation of a person, which can be (...) used in research, yet offers the possibility of counseling and intervention.

Summary This 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 hypothetical term, isolated systems. An application of experimentum crucis in Experimental Phenomenology of perception is presented. In conclusion, the role of perceptual knowledge as an essential assumption in other (...) scientific disciplines that have a high degree of theoricity is also underlined. (shrink)
