The Experimental Phenomenology of Perception. A Collective Reflection on the Present and Future of this Approach

The Experimental Phenomenology of Perception is a research approach in Psychology in Italy that is inspired by Gestalt Psychology, with its own specific theoretical differences. Several scholars have contributed to this approach, each with their own interpretation and willingness to integrate ideas from other approaches. The starting point for this approach is a careful investigation of the structure of perceptual phenomena, which some see as the final objective. The theoretical premises and methodologies of this approach have been rigorously discussed and are part of an established tradition of thought, although they can still be further developed. The question is whether this approach is the only way to contribute to contemporary Cognitive Sciences, or if there are other ways in which it can be important

Does Thinking in Opposites in Order to Think Differently Improve Creativity?

In this paper, we focus on the link between thinking in opposites and creativity. Thinking in opposites requires an intuitive, productive strategy, which may enhance creativity. Given the importance of creativity for the well-being of individuals and society, finding new ways to enhance it represents a valuable goal in both professional and personal contexts. We discuss the body of evidence that exists concerning the importance of the first representation of the structure of a problem to be solved, which determines the baseline representation and sets limits on the area within which a problem solver will explore. We then review a variety of interventions described in the literature on creativity and insight problem solving that were designed to overcome fixedness and encourage people to move away from stereotypical solutions. Special attention is paid to the research carried out in the context of problem solving, which provides evidence that prompting people to "think in opposites" is beneficial. We suggest that an extended investigation of the effects of this strategy in various types of tasks related to creativity is an interesting line of research to follow. We discuss the rationale supporting this claim and identify specific questions, both theoretical and methodological, for future research to address

The sensorial experience of wine for nonexperts: How the terms frequently used in Italian guidebooks are understood by standard consumers in Vietnam

Opposites are central to many areas in the fields of Psychology and Linguistics, but they are also fundamental to the technical scales used to describe wine (e.g., the Wine and Spirit Education Trust evaluation scales). The present study explores whether it is useful to refer to opposites in order to model Vietnamese standard (vs. expert) consumers' understanding of the wine descriptors frequently used in Italian texts. Sixty-four terms used in Product Specifications and popular Italian wine guidebooks to talk about the sensory properties of red and white wines (e.g., Hazy\u2014 Viet. \u110\u1ee5c; Bright\u2014Viet Sang; Complex\u2014Viet Nhi\u1ec1u h\u1b0\u1a1ng v\u1ecb; Immature\u2014Viet Ch\u1b0a ng\u1ea5u, etc.) were presented to 300 Vietnamese native speakers. They were asked to select what they considered to be the opposite property. Opposites were easily found by the participants, and, interestingly, they agreed with each other on those which were the most frequently chosen. Thought-provoking similarities and differences were revealed when these finding were compared with those of a twin study involving Italian participants. Practical Applications: In order to ensure effective marketing in the wine industry and to prevent misunderstandings, it is not only important that the dimensions underlying certain terms used by experts (i.e., sommeliers, oenologists, and wine experts) are similar to those understood by nonexperts (i.e., standard consumers), but it is also vital to ascertain whether nonexperts belonging to different cultures understand the same terms in a similar way. The results emerging from the present study suggest that it may be useful to use opposites to describe the sensory properties of wine to Vietnamese standard consumers, just as it is for Italian consumers. The research resulted in a list of terms which are understood in a similar way and another list with those which are understood differently. From an applicative point of view, this may be interesting for the marketing of wine in international contexts

Lung-deposited surface area concentration measurements in selected occupational and non-occupational environments

AbstractPrevious experimental and epidemiologic studies suggested that exposure to ultrafine particles (UFP) may result in adverse health effects. Metrics such as the number-concentration and especially the surface-area or lung-deposited surface area (LDSA) appear to be appropriate metrics of dose for predicting pulmonary inflammation of insoluble and poorly soluble ultrafine particles. Currently not much data including LDSA concentrations is available. The aim of this study was therefore to measure LDSA concentrations in a variety of occupational and non-occupational environments as well as in chamber tests. To this end, novel handheld online-monitors were deployed and evaluated for their suitability to be used in a variety of micro-environments and under different conditions. Chamber emissions tests included incense and candle burning, 3D printing and cigarette/e-cigarette smoking. The LDSA concentration was measured in occupational environments such as a canteen kitchen, a welding workshop and in a car. Measurements were also conducted in a private house with a wood-burning stove and with ongoing parallel cooking activities. Depending on the type of micro-environment, the ongoing activities or the material investigated in the chamber-tests, large differences were observed in terms of measured LDSA concentrations, some exceeding up to 1000 times that of the baseline concentration detected before activities initiated. In some of the investigated environments LDSA concentrations were measured for the first time. The data might therefore serve as reference for future studies. The handheld instrument used to measure this data worked well both for stationary measurements as well as for personal monitoring and proved to be an alternative to bulkier benchtop instruments

Opposition and Identicalness: Two Basic Components of Adults' Perception and Mental Representation of Symmetry

Symmetry is a salient aspect of biological and man-made objects, and has a central role in perceptual organization. Two studies investigate the role of opposition and identicalness in shaping adults’ naïve idea of “symmetry”. In study 1, both verbal descriptions of symmetry (either provided by the participants or selected from among alternatives presented by the experimenter) and configurations drawn as exemplars of symmetry were studied. In study 2, a pair comparison task was used. Both studies focus on configurations formed by two symmetrical shapes (i.e., between-objects symmetry). Three main results emerged. The explicit description of symmetry provided by participants generally referred to features relating to the relationship perceived between the two shapes and not to geometrical point-by-point transformations. Despite the fact that people tended to avoid references to opposition in their verbal definition of symmetry in study 1, the drawings that they did to represent their prototypical idea of symmetry manifested opposition as a basic component. This latter result was confirmed when the participants were asked to select the definition (in study 1) or the configuration (in study 2) that best fitted with their idea of symmetry. In conclusion, identicalness is an important component in people’s naïve idea of symmetry, but it does not suffice: opposition complements it

Sensory modality profiles of antonyms

Adjectives that are used to describe sensory experiences are often used to express more than one modality. The adjective sweet, for instance, may primarily be associated with taste (i.e., taste is the dominant modality of sweet), but it can also be used for smell, sound or sight, and possibly even for touch. It has also been shown that some sensory modalities combine more easily than others. Many adjectives that are used to describe taste, for instance, can also be used for smell, but, less likely, for sound. These associations between sensory modalities as they are expressed in language are the topic of this study. We looked at the distribution of the combinations of dominant modalities in pairs of antonymic sensory adjectives (e.g., sweet-sour), and how the dominant modality of the adjectives in these pairs differed from that of the adjectives in isolation. In our dataset, there was a sizeable number of pairs consisting of adjectives with differing dominant modalities. Within those pairs, we observed that adjectives with the dominant modality sight can also be used for touch and vice versa. Similarly, adjectives with the dominant modality of smell can also be used for taste and vice versa. Finally, adjectives with the dominant modalities sight and touch can both also be used for hearing and for taste, but not the other way around. These results contribute to our understanding of how language is used to describe sensory experiences, and, with that, how sensory experiences may be shaped by the words that we use to describe them

Characterisation of mainstream and passive vapours emitted by selected electronic cigarettes

AbstractElectronic cigarettes have achieved growing popularity since their introduction onto the European market. They are promoted by manufacturers as healthier alternatives to tobacco cigarettes, however debate among scientists and public health experts about their possible impact on health and indoor air quality means further research into the product is required to ensure decisions of policymakers, health care providers and consumers are based on sound science. This study investigated and characterised the impact of ‘vaping’ (using electronic cigarettes) on indoor environments under controlled conditions using a 30m3 emission chamber. The study determined the composition of e-cigarette mainstream vapour in terms of propylene glycol, glycerol, carbonyls and nicotine emissions using a smoking machine with adapted smoking parameters. Two different base recipes for refill liquids, with three different amounts of nicotine each, were tested using two models of e-cigarettes. Refill liquids were analysed on their content of propylene glycol, glycerol, nicotine and qualitatively on their principal flavourings. Possible health effects of e-cigarette use are not discussed in this work. Electronic cigarettes tested in this study proved to be sources for propylene glycol, glycerol, nicotine, carbonyls and aerosol particulates. The extent of exposure differs significantly for active and passive ‘vapers’ (users of electronic cigarettes). Extrapolating from the average amounts of propylene glycol and glycerol condensed on the smoking machine filter pad to the resulting lung-concentration, estimated lung concentrations of 160 and 220mgm−3 for propylene glycol and glycerol were obtained, respectively. Vaping refill liquids with nicotine concentrations of 9mgmL−1 led to vapour condensate nicotine amounts comparable to those of low-nicotine regular cigarettes (0.15–0.2mg). In chamber studies, peak concentrations of 2200μgm−3 for propylene glycol, 136μgm−3 for glycerol and 0.6μgm−3 for nicotine were reached. Carbonyls were not detected above the detection limits in chamber studies. Particles in the size range of 20nm to 300nm constantly increased during vaping activity and reached final peak concentrations of 7×106particlesL−1. Moreover, the tested products showed design flaws such as leakages from the cartridge reservoirs. Possible long term effects of e-cigarettes on health are not yet known. E-cigarettes, the impact of vaping on health and the composition of refill liquids require therefore further research into the product characteristics. The consumers would benefit from harmonised quality and safety improvements of e-cigarettes and refill liquids

Pleasures of the Mind: What Makes Jokes and Insight Problems Enjoyable

In this paper, a parallel analysis of the enjoyment derived from humor and insight problem solving is presented with reference to a \u201cgeneral\u201d Theory of the Pleasures of the Mind (TPM) (Kubovy, 1999) rather than to \u201clocal\u201d theories regarding what makes humor and insight problem solving enjoyable. The similarity of these two cognitive activities has already been discussed in previous literature in terms of the cognitive mechanisms which underpin getting a joke or having an insight experience in a problem solving task. The paper explores whether we can learn something new about the similarities and differences between humor and problem solving by means of an investigation of what makes them pleasurable. In the first part of the paper, the framework for this joint analysis is set. Two descriptive studies are then presented in which the participants were asked to report on their experiences relating to solving visuo-spatial insight problems (Study 1) or understanding cartoons (Study 2) in terms of whether they were enjoyable or otherwise. In both studies, the responses were analyzed with reference to a set of categories inspired by the TPM. The results of Study 1 demonstrate that finding the solution to a problem is associated with a positive evaluation, and the most frequent explanations for this were reported as being Curiosity, Virtuosity and Violation of expectations. The results of Study 2 suggest that understanding a joke (Joy of verification) and being surprised by it (Feeling of surprise) were two essential conditions: when they were not present, the cartoons were perceived as not enjoyable. However, this was not enough to explain the motivations for the choice of the most enjoyable cartoons. Recognizing a Violation of expectations and experiencing a diminishment in the cleverness or awareness initially attributed to the characters in the cartoon were the aspects which were most frequently indicated by the participants to explain why they enjoyed the joke. These findings are evaluated in the final discussion, together with their limitations and potential future developments
