Recognition of briefly presented familiar and unfamiliar faces
2009
Early processing stages in the perception of familiar and unfamiliar faces were studied in four experiments by varying the type of available facial information in a four alternative forced choice recognition task. Both reaction time and recognition accuracy served as dependent measures. The observed data revealed an asymmetry in processing familiar and unfamiliar faces. A markedly weak inversion effect and strong blurring effect suggest a limited usage of spatial relations within early processing stages of unfamiliar faces. Recognition performance for whole familiar faces did not deteriorate due to blurring or the presentation of isolated internal features, suggesting a low level of represe…
Children and Parental Barriers to Active Commuting to School: A Comparison Study
2021
The main objectives of this study were: to compare the barriers to active commuting to and from school (ACS) between children and their parents separately for children and adolescents; and to analyze the association between ACS and the children’s and parents’ barriers. A total of 401 child–parent pairs, from Granada, Jaén, Toledo and Valencia, self-reported, separately, their mode of commuting to school and work, respectively, and the children’s barriers to ACS. T-tests and chi-square tests were used to analyze the differences by age for continuous and categorical variables, respectively. Binary logistic regressions were performed to study the association between ACS barriers of children an…
Samotni ojcowie w percepcji dzieci
2019
Zagadnienie samotnego ojcostwa stanowi jeden z bardziej interesujących, aczkolwiek nadal mało zgłębionych, obszarów badań nad rodziną i rodzicielstwem. Celem tego opracowania jest poznanie sposobu, w jaki dzieci postrzegają swoich samotnie opiekujących się nimi ojców. W tym celu wykorzystano wyniki arbitralnie wybranych badań ilościowych i jakościowych, przeprowadzonych w ostatnich czterech dekadach. Jednym z wniosków, sformułowanych w prezentowanym artykule, jest stanowisko, że aktualny stan badań nad percepcją dzieci w zakresie oceny ich samotnie wychowujących je ojców jest niezadowalający. Istnieje zatem konieczność prowadzenia dalszych badań w tym zakresie.
Społeczna percepcja energetyki wiatrowej na przykładzie farmy wiatrowej Kuniów
2017
Przeprowadzono badania ankietowe wśród mieszkańców wsi Kuniów w południowo-zachodniej Polsce, dotyczące pozytywnych i negatywnych aspektów budowy oraz funkcjonowania farmy wiatrowej. Ocenie poddano farmę 2 elektrowni wiatrowych o mocy 2 MW każda, z wysokością wież 110 m, długością rotorów 45 m i odległością od zabudowy 620 i 1300 m. W ocenie ankietowanych głównymi pozytywnymi aspektami rozwoju energetyki wiatrowej są: czysta energia, tania energia oraz zwiększenie możliwości rozwoju gminy i wsi z podatków. Największe zagrożenia obejmują: degradację krajobrazu, zabijanie ptaków i nietoperzy, utratę siedlisk zwierząt, hałas, infradźwięki oraz wibracje. Postrzeganie energetyki wiatrowej po wyb…
In-mouth mechanism leading to the perception of fat in humans: from detection to preferences. The particular role of saliva
2013
In humans, the perception of fat in food is a complex process involving many sensory modalities (texture, aromaand flavour). Themouth is the first place in which the process of digestion begins. During this process, a bolus is formed in which saliva is significantly incorporated. For solids and semi-solid fatty matrices, saliva and the shear forces applied during mastication contribute to their breakdown and/or destabilisation in emulsified systems. These mechanisms are often dependent on the fat content of the food and thus play an important role in not only the perception of texture but also the release of compounds responsible for the flavour of “fat”. In addition, saliva is directly inv…
A Curvature Based Method for Blind Mesh Visual Quality Assessment Using a General Regression Neural Network
2016
International audience; No-reference quality assessment is a challenging issue due to the non-existence of any information related to the reference and the unknown distortion type. The main goal is to design a computational method to objectively predict the human perceived quality of a distorted mesh and deal with the practical situation when the reference is not available. In this work, we design a no reference method that relies on the general regression neural network (GRNN). Our network is trained using the mean curvature which is an important perceptual feature representing the visual aspect of a 3D mesh. Relatively to the human subjective scores, the trained network successfully asses…
Gender-Typed Sport Practice, Physical Self-Perceptions, and Performance-Related Emotions in Adolescent Girls
2020
Youth sport experience provides opportunities for physical, personal, and social development in youngsters. Sport is a social system in which socially constructed gender differences and stereotypes are incorporated, and specific sport activities are often perceived as gender characterized. The objective of this study was to examine the relationship between some salient physical and emotional self-perceptions and the type of sport practiced. A sample of 261 female athletes, aged 14–21 years (Mage = 15.59, SD = 2.00), practicing different sports, categorized as feminine (e.g., artistic and rhythmic gymnastics), masculine (e.g., soccer and rugby), or neutral (e.g., track and field and tennis),…
