Sugar: The master of disguise
Guedes, D.; Prada, M.Sugar is almost everywhere. You can find it in your favorite treats, like candies, cookies, ice cream, or soda. But sugar is also hidden in places you may not expect, like yogurt, breakfast cereals, or even bread. In this article, you will learn more about how sugar sneaks into our daily foods, its effects on our bodies and minds, and how to spot it so you can make smarter choices to keep a healthy diet.
Some sweeteners are tastier than others?! Examining the impact of knowing the t...
Prada, M.; Guedes, D.; Doros, A.; Saraiva, M.Cues related to a product's composition can influence consumer perceptions of food items. For example, information about the type of sweetener used may affect perceptions of healthfulness, caloric content, and expected taste. This study builds on this topic by examining the effect of consumer awareness of sweetener ingredients on their evaluation of lemonade. Participants (n = 101) tasted five samples of lemona...
Como implementar estudos normativos
Guedes, D.; Prada, M.Este capítulo visa: (a) enquadrar as motivações para o desenvolvimento de estudos normativos; (b) descrever as etapas de desenvolvimento de bases de estímulos e respetivos dados normativos; (c) identificar principais cuidados e boas práticas no desenvolvimento e disseminação de estudos normativos.
What does sustainability sound like? Crafting soundscapes that reflect environm...
Rodríguez, B.; Guedes, D.; Graça, J.; Reyes, L. H.; Garrido, M. V.; Prada, M.; Reinoso-Carvalho, F.This paper presents a series of studies examining how soundscapes can convey the abstract and multidimensional concept of sustainability. A pilot study identified sensory and affective descriptors linked to sustainability (e.g., natural, responsible), which were then used to determine psychoacoustic properties (e.g., pitch, consonance) capable of communicating these descriptors. Based on these properties, ten i...
Tasting in tune: The influence of music on taste evaluation under visual maskin...
Guedes, D.; Prada, M.; Garrido, M. V.This study investigates the effect of music on the evaluation of drinks presented unmasked (in open cups) or masked (in closed cups with opaque lids). Participants tasted five drink samples (varying in color and flavor) while listening to a sweet (SW) and a non-sweet (NS) soundtrack (within participants). Listening to the SW (vs. NS) soundtrack significantly increased the reported sweetness of drinks, whereas t...
O pré-registo como prática de ciência aberta
Guedes, D.; Rodrigues, D. L.O pré-registo consiste na submissão de um plano de investigação previamente à sua implementação. Esta submissão resulta num registo datado (timestamped) onde se especificam as questões ou hipóteses de partida, bem como os métodos de recolha e análise de dados que se prevê utilizar. Este procedimento enquadra-se no conjunto de práticas de ciência aberta, cujo objetivo é aumentar a transparência e acessibilidade ...
Dentro ou fora da norma: Estudos normativos no contexto da validação de estímulos
Prada, M.; Guedes, D.A investigação em Psicologia requer frequentemente a utilização de materiais de diferentes naturezas como imagens, palavras, sons ou vídeos. Por exemplo, um/a investigador/a interessado/a em implementar uma tarefa de decisão lexical saberá que tem de selecionar um conjunto de estímulos verbais que incluem tanto palavras como sequências de letras que se assemelham a palavras (i.e., pseudo-palavras). Obviamente q...
Normative ratings for the Kitchen and Food Sounds (KFS) database
Prada, M.; Guedes, D.; Garrido, M. V.; Saraiva, M.Sounds are important sensory cues for food perception and acceptance. We developed and validated a large-scale database of kitchen and food sounds (180 stimuli) capturing different stages of preparing, cooking, serving, and/or consuming foods and beverages and sounds of packaging, kitchen utensils, and appliances. Each sound was evaluated across nine subjective evaluative dimensions (random order), including st...
Disentangling cross-modality and affect in “sonic seasoning”: The effect of mus...
Guedes, D.; Garrido, M. V.; Lamy, E.; Prada, M.The presence of music while eating can influence how foods are perceived. One line of inquiry has focused on the potential of music to evoke taste-related associations (such as perceiving a song as “sweet”) to enhance the perception of congruent taste/flavor attributes in foods. However, music is also an expression of emotion, and its influence on mood has been put forward as an alternative explanation to why m...
Sweet music influences sensory and hedonic perception of food products with var...
Guedes, D.; Prada, M.; Lamy, E.; Garrido, M. V.Reducing sugar intake is an important nutritional goal in most developed countries. Despite the health consequences of excessive sugar consumption (e.g., non-communicable diseases), individuals are often reluctant to shift dietary habits due to the high hedonic appeal of sugar-rich products. Manipulating the intrinsic sensory attributes of foods (such as color or aroma) has been put forward as a promising frame...
