Individuals constantly modulate their exploratory movements and adapt their internal hypotheses to incoming sensory information to achieve a thorough and realistic percept. Perception depends on the exploratory movements as well as influencing them. While this seems to be common sense, scientifically we know very little about the temporal dynamics during haptic exploration. To address this, we investigated the exploratory force modulations of two groups of healthy young adults during the exploration of grated surfaces with differing detection difficulty during successive (n = 20) and random stimulus presentation (n = 20). Results showed that exploratory force depended on stimulus properties and increased with increasing detection difficulty. Both experiments yielded the same direction of results with slightly smaller effects in the random stimulus presentation group. Across exploration time average fingertip force also increased. The biggest increase occurred systematically at the beginning (within the first 40 percent) of exploration time per stimulus indicating that most critical information is received during the initial contact phase and is directly transformed into the exploration procedure and force application. Furthermore, video-analyses and comparisons to our high temporal resolution data revealed strong dynamic changes in pressure application during test stimulus exploration with differences in the force dynamics and exploration strategies of simple and difficult stimuli.

Master of Science / Food Science Institute - Food, Nutrition, Dietetics and Health / Edgar Chambers IV / Sensory perception and hedonic response to foods and beverages depend not only on the characteristics of the food or beverage product, but also on the physiological and psychological state of the person consuming it. Physical exercise provokes physiological changes in human subjects including dehydration through sweat loss and depletion of energy stores, and emotional changes including increased fatigue and vigor; as such it is expected to affect the sensory and hedonic response to foods consumed immediately post-workout. Exercise and proper diet are both well-recognized components of a healthy lifestyle; it is therefore critical to understand how an acute bout of exercise or a chronic training regimen might affect the eating behavior of the exerciser. This review examines published studies -- both interventional and observational -- on the effect of acute and chronic physical exercise on thirst, hunger, perception and liking of the five basic tastes, and macronutrient choice. This review also touches on macronutrient choice and psychological factors of food choice such as compensatory eating and food restraint. Results suggest that acute exercise of a certain threshold intensity effects consistent perceptual and hedonic changes across the population: immediate hunger suppression, osmoregulatory thirst, increased palatability of salt, increased perception and palatability of sweetness, and decreased perception and palatability of sourness. Effects on bitter and umami appear more limited. However, individual metabolic and psychological variation modulate these effects, and the effects of chronic exercise are complicated by concurrent lifestyle changes and not properly understood through observational studies alone.

The value of architecture lies in our sensory perception, our experience of the space. If the space creates an awareness of the present through the sensory exchange between our body, mind, and the architecture, then it is committed to memory as a place. The perception of a space cannot be controlled by the architect, it is subjective. The architect can control the idea or philosophy of the design as well as the formal aspects such as structure, materiality, spatial organization and proportion. Through these formal aspects the architect strives to make the intention physical. Successful architecture should facilitate this sensory exchange or communication on many scales. It should speak directly to us through it's immediate physical manifestation and spatial experience as well as through it's ability to make a grander connection to it's situation. As stated in Questions of Perception- Phenomenology of Architecture, "Architecture, more fully than other art forms, engages the immediacy of our sensory perceptions. The passage of time; light, shadow, and transparency; color phenomena, texture, material, and detail all participate in the complete experience of architecture."The essence of a library is a place for introspection and study or even meditation. Therefore silence is a significant aspect of this project in regard to producing a structure that is quiet and subtle in its forms and spaces. / Master of Architecture

Esta pesquisa de mestrado dispõe-se a estudar as relações existentes entre a percepção sensorial têxtil e o corpo vestido, sob a perspectiva de mulheres videntes e não videntes, buscando as semelhanças e diferenças entre essas formas de percepção para assim refletir sobre a ação dos sentidos na interação com o produto têxtil e, mais especificamente, a influência da visão na percepção tátil. Para isso, foram realizadas pesquisas teóricas e práticas que abordam a relação simbólica do tecido com a sociedade, tendo como base a observação de um grupo formado por 45 mulheres com cegueira total congênita, adquirida e também por mulheres dotadas do sentido da visão. Os diálogos estabelecidos na relação do universo feminino e do têxtil como matéria-prima base para a criação das roupas e como as diversas variações de tecidos e suas funções em contato com a pele estimulam diferentes sensações, buscando enfatizar a importância da percepção e sua influência nas preferências e escolhas de consumo de produtos de moda. Com o objetivo de analisar como é possível estabelecer diferentes formas de perceber o tecido e o corpo que o veste e a maneira como auxiliam na formação da identidade visual como elemento constitutivo de uma cultura contemporânea / This dissertation proposes to study the relations between the textile sensorial perception and the dressed body under the perspective of seeing and non-seeing women, researching the similarities and differences from these ways of perception and, specifically, the visions influence over the textile perception. For this, it was made several theoretical and practical researches that approaches the fabrics symbolic relation with the society, which was based on the observation of a group with 45 women with congenital total blindness, by women who have acquired it and also by seing women. The dialogues stated in the relation between the feminine universe and the textile as an element to the creation of clothes and how different tissues and its functions in contact with the skin stimulates different sensations, seeking to emphasize the importance of the perception and its influence on personal preferences and fashion produts consumptions choices. It was analyzed how it is possible to connect different ways of perceiving the fabric and the body that wears it so that assists on the formation of the visual identity as an element to institute a contemporary culture
