We systematically compared beliefs about animal (e.g., "lion"), artifactual (e.g., "hammer"), and institutional (e.g., "police officer") categories, aiming to identify whether people draw different inferences about which categories are subjective and which are socially constituted. We conducted two studies with 270…

Comprehensive understanding of complex biological systems necessitates the use of computational models because they facilitate visualisation and interrogation of system dynamics and data-driven analysis. Computational model-based (CMB) activities have demonstrated effectiveness in improving students' understanding and their ability to use and…

Visual appearance is one of the main cues children rely on when categorizing novel objects. In 3 studies, testing 128 3-year-olds and 192 5-year-olds, we investigated how various kinds of information may differentially lead children to overlook visual appearance in their categorization decisions across domains. Participants saw novel animals or…

This paper studies conceptions of woodwind students regarding learning and teaching music, within the framework of implicit theories. It analyzes whether there are differences related to participants' instruction level, and whether it is possible to identify profiles according to their conceptions. Sixty-eight students from three different levels…

From an integrative approach, this work focuses on the role of conceptual mechanisms, such as comparison and conceptual-based inference, and sociopragmatic support in young children's taxonomic categorization. "Experiment 1" assessed whether 3-, 4-, and 6-year-old children succeed in detecting taxonomic relations on their own. A…

We conducted three experiments to study the role of instrumental (e.g. "knife-bread") and categorical (e.g. "cake-bread") relations in the development of conceptual organization with a priming paradigm, by varying the nature of the task (naming--Experiment 1--or categorical decision--Experiments 2 and 3). The participants were 5-, 7- and…

Embodied views of cognition propose that concepts are grounded in sensorimotor experience. Diverse aspects of sensorimotor experience, like action and context information, could play a key role in the formation and processing of manipulable object concepts. Specifically, contextual information could help to link specific actions experienced with…

The current study evaluated the relative roles of conceptual knowledge and executive control on the development of "categorical flexibility," the ability to switch between simultaneously available but conflicting categorical representations of an object. Experiment 1 assessed conceptual knowledge and executive control together; Experiment 2…

Children's worlds are increasingly populated by intelligent technologies. This has raised a number of questions about the ways in which technology can change children's ideas about important concepts, like what it means to be alive or smart. In this study, we examined the impact of experience with intelligent technologies on children's ideas about…

Two studies investigated the relationship between learning names and learning concepts in preschool children. More specifically, we focused on the relationship between learning the names and learning the intended functions of artifacts, given that the intended function of an artifact is generally thought to constitute core conceptual information…

Research into children's ideas showed that children's interpretations of natural phenomena often differ from those of scientists. The aim of our study was to identify children's ideas of various age classes (7/8-14/15) about birds. A questionnaire with 31 multiple choice and open ended questions and eight photographs were administered to 495…

Generic sentences (such as "Birds lay eggs") are important in that they refer to kinds (e.g., birds as a group) rather than individuals (e.g., the birds in the henhouse). The present set of studies examined aspects of how generic nouns are understood by English speakers. Adults and children (4- and 5-year-olds) were presented with scenarios about…

When children learn categories, they do not learn isolated facts but rather systems of knowledge. These systems of knowledge are composed of property-property (e.g., things with wings tend to have feathers), property-role (e.g., things with eyes tend to eat), and role-role (e.g., things that eat tend to sleep) correlations. Research has shown that…

Visual preference procedures were used to investigate development of perceptually based subordinate-level categorization in 3- to 7-month-old infants. Experiments 1 and 2 demonstrated that 3- to 4-month-olds did not form category representations for photographic exemplars of subordinate-level classes of cats and dogs (i.e., Siamese vs. Tabby,…

Previous research has shown that 3- to 4-month-old infants form a global categorical representation for cats that includes female lions, whereas 6- to 7-month-old infants differentiate between cats and lions. Three experiments using familiarization-novelty preference procedures attempted to determine whether the differentiation of a global…
