Reducing the Bias: How Perspective Taking Affects First- and Third-Person Perceptions of Media Influence
2017
Third- and first-person perceptions (TPPs/FPPs) are considered to be biased judgments of media influence on self and others. Research suggests that perspective taking, i.e., thinking from another person’s position, decreases perceptual gaps between self and others via assimilation. In a two-factorial experiment (n = 431), we test whether this effect of perspective taking (Factor 1) holds true for the presumed influence of desirable and undesirable messages (Factor 2). Results indicate that perspective taking significantly reduces TPPs in the case of an undesirable message but not FPPs that are provoked by the desirable message. The observable effect traces back to a change in presumed messa…
Practiced musical style shapes auditory skills
2012
Musicians' processing of sounds depends highly on instrument, performance practice, and level of expertise. Here, we measured the mismatch negativity (MMN), a preattentive brain response, to six types of musical feature change in musicians playing three distinct styles of music (classical, jazz, and rock/pop) and in nonmusicians using a novel, fast, and musical sounding multifeature MMN paradigm. We found MMN to all six deviants, showing that MMN paradigms can be adapted to resemble a musical context. Furthermore, we found that jazz musicians had larger MMN amplitude than all other experimental groups across all sound features, indicating greater overall sensitivity to auditory outliers. Fu…
Collaborative Policy Making and Stakeholder Engagement: A Resident–Based Perspective
2019
This study analyses residents’ perceptions and attitudes towards tourism and community engagement with tourism planning. Overall, residents think that the positive effects of tourism development outweigh the negative impacts. Despite this, they express concerns regarding the economic future of their area and that the tourism development in their area is mostly exogenously driven. Further, they do not feel involved in tourism planning but, quite surprisingly, they do not seems to be convinced that local authorities should encourage community participation in tourism decision making. Exploratory factor analysis and hierarchical and non-hierarchical cluster analysis were therefore conducted. F…
: une évaluation des perceptions des enseignants
2017
International audience; Le discours des experts et des organisations internationales, de même que les initiatives des politiques et mouvements en faveur de l'émancipation des personnes handicapées sont orientés vers la construction d'une école pour tous (Ainscow et al., 2003 ; Déclaration de Salamanque, 1994 ; Conférence de Dakar, 2000 ; Convention relative aux droits des personnes handicapées, 2006). L'inclusion scolaire implique des modifications et des bouleversements tant dans les pratiques enseignantes que sur le plan de l'organisation scolaire dans son ensemble. Il importe de s'intéresser aux perceptions des enseignants envers la politique nationale visant l'inclusion à l'école ordina…
Stakeholders’ Attitudes about the Transplantations of the Mediterranean Seagrass Posidonia oceanica as a Habitat Restoration Measure after Anthropoge…
2021
Anthropogenic impacts on Posidonia oceanica meadows have led to a decline of this ecosystem throughout the Mediterranean. Transplantations have often been prescribed as a compensation measure to mitigate the impacts caused by coastal maritime works. Here a Q methodology approach was used to investigate the stakeholders’ attitudes in four case studies of P. oceanica transplants realized in Italian waters. Twenty-two respondents were asked to score 37 statements, and the resultant Q-sorting was analyzed via an inverse PCA using the KADE software. Four discourses, corresponding to the significant axes in the factorial analysis were identified: science and conservation (F1), oriented at a rigor…
Identifying individuality and variability in team tactics by means of statistical shape analysis and multilayer perceptrons.
2012
Abstract Offensive and defensive systems of play represent important aspects of team sports. They include the players’ positions at certain situations during a match, i.e., when players have to be on specific positions on the court. Patterns of play emerge based on the formations of the players on the court. Recognition of these patterns is important to react adequately and to adjust own strategies to the opponent. Furthermore, the ability to apply variable patterns of play seems to be promising since they make it harder for the opponent to adjust. The purpose of this study is to identify different team tactical patterns in volleyball and to analyze differences in variability. Overall 120 s…
Day-ahead forecasting for photovoltaic power using artificial neural networks ensembles
2016
Solar photovoltaic plants power output forecasting using machine learning techniques can be of a great advantage to energy producers when they are implemented with day-ahead energy market data. In this work a model was developed using a supervised learning algorithm of multilayer perceptron feedforward artificial neural network to predict the next twenty-four hours (day-ahead) power of a solar facility using fetched weather forecast of the following day. Each set of tested network configuration was trained by the historical power output of the plant as a target. For each configuration, one hundred networks ensembles was averaged to give the ability to generalize a better forecast. The train…
Attentional vs computational complexity measures in observing paintings
2009
Because of the great heterogeneity of subjects and styles, esthetic perception delineates a special and elusive field of research in vision, which represents an interesting challenge for cognitive science tools. With specific regard to the role of visual complexity, in this paper we present an experiment aimed to measure this dimension in a heterogeneous set of paintings. We compared perceived time complexity measures - based on a temporal estimation paradigm - with physical and statistical properties of the paintings, obtaining a strong correlation between psychological and computational results.
An automatic system for humanoid dance creation
2016
Abstract The paper describes a novel approach to allow a robot to dance following musical rhythm. The proposed system generates a dance for a humanoid robot through the combination of basic movements synchronized with the music. The system made up of three parts: the extraction of features from audio file, estimation of movements through the Hidden Markov Models and, finally, the generation of dance. Starting from a set of given movements, the robot choices sequence of movements a suitable Hidden Markov Model, and synchronize them processing musical input. The proposed approach has the advantage that movement execution probabilities could be changed according evaluation of the dance executi…
Modelling the Effects of Internal Textures on Symmetry Detection Using Fuzzy Operators
2009
Symmetry is a crucial dimension which aids the visual system, human as well as artificial, to organize its environment and to recognize forms and objects. In humans, detection of symmetry, especially bilateral and rotational, is considered to be a primary factor for discovering and interacting with the surrounding environment. Rotational symmetry detecting can be affected by less-known factors, such as the stimulus internal texture. This paper explores how fuzzy operators can be usefully employed in modeling the effects of the internal texture on symmetry detection. To this aim, we selected two symmetry detection algorithms, based on different computational models, and compared their output…
