DEVELOPMENT OF A TEST FOR EVALUATING THE CONCEPTUAL KNOWLEDGE OF CHEMICAL EQUILIBRIUM CONSTANT AMONG UNIVERSITY STUDENTS AND ITS APPLICATION TO SPANI…
2014
This article outlines a procedure that was used to develop a written test for evaluating the conceptual knowledge of chemical equilibrium constant among university students. The concepts in the subject matter were carefully defined through propositional statements. Students' understanding of the topic was determined through interviews. These data were used to produce nine multiple choice questions. Each question was designed to identify misconceptions related to the chemical equilibrium constant. The test was evaluated by foure associate professors and was administred to a total of 196 spanish university students. This test has a Cronbach's alpha reliability of 0.63 and its content validity…
Spilling the beans: The development of conceptual knowledge about food and its links with food rejection in young children (3-7-years-old)
2021
Insufficient dietary variety in children leads to significant nutrient deficiencies and health issues, both in childhood and later life (DeCosta et al., 2017). Cognitive mechanisms, such as categorization and conceptual knowledge, play an important role in understanding and appropriately accepting or rejecting foods (Mura Paroche et al., 2017). The food domain lends itself to many concepts and categories, such as taxonomic (i.e., lamb is meat), thematic (i.e., lamb goes on a plate), or script (i.e., lamb is eaten at dinner). Such knowledge aids accurate recognition, understanding, and appropriate interaction when confronted with foods situated in context. If conceptual knowledge is underdev…
A categorization and executive functions approach of food rejection in young children
2021
Food neophobia and pickiness are two strong psychological obstacles to young children’s consumption of fruits and vegetables, which are necessary components of a diet that facilitates normal and healthy development. It is therefore of critical importance to investigate the cognitive underpinnings of these two kinds of food rejection to promote the adoption of healthy eating behaviors. Food acceptance and rejection appear to be partly conditioned by children’s knowledge of the food domain. Knowledge allows children to recognize a given food, categorize it, and make inference-based decisions on its properties and possible consequences of consumption. Underdeveloped knowledge may cause food st…
Les expertises dans le domaine du vin : cas du concept de vin de garde
2010
Wine expertise : the case of "vin de garde" concept. This work aimed to investigate different types of knowledge and skills involved in wine expertise. This work is based on the “vin de garde” concept, we first broadened the study of this concept, and we identified gustatory (astringency and acidity) and olfactory (woody, burnt, vanilla and prune notes) clues used by wine professionals from Bourgogne to judge the aging potential of red wines from Bourgogne. The expertise is investigated through two studies. In the first study, we examined if the environment in which professionals practise leads to specific perceptive skills and conceptual knowledge regarding wines with an aging potential. W…
Preserved knowledge maps of countries: Implications for the organisation of semantic memory
2004
We describe two patients with selectively preserved knowledge of the category of countries. Following a series of cerebra infarcts, patient DB presented with severe perceptual impairment, including dense apperceptive agnosia, prosopagnosia, an topographical agnosia. Despite these deficits, he could effortlessly name countries from their outline maps. Patient WH, who suffered from semantic dementia, had severe naming and comprehension difficulties, with extremely sparse residual semantic knowledge. Remarkably, the category of countries was preserved. First, we argue that, for both patients, this category preservation occurs at a semantic level. Second, we discuss our findings in the context …
