This study sought to analyze senior dental students' cognitive structure concerning the topic of "enamel", which is fundamentally important for understanding oral health, since it offers basic scientific concepts for clinical and preventive practices and is the main subject of several courses during dentistry training. The strategy used to analyze students' cognitive structures was Novak's Conc...

The purpose of this paper is to describe a fuzzy cognitive map based on the random neural network model, and to illustrate its application in the modeling of process. This model is based on the probability of activation of the neurons/concepts in the network. Our model carries out inferences via numerical calculation instead of symbolic deduction. The arcs define dynamic relationships between c...

In cognitive psychology, concepts are those data structures that are stored in long-term memory and are used by default in human beings’ higher cognitive processes (categorization, inductive and deductive reasoning...). Most psychologists of concepts assume that these mental representations share many scientifically important properties, and the psychology of concepts is expected to describe th...

Using an ontology to automatically generate questions for ordinary people requires a structure and concepts compliant with human thought. Here we present methods to develop a pragmatic, expert-based and a basic-level ontology and a framework to evaluate these ontologies. Comparing these ontologies shows that expert-based ontologies are most easy to construct but lack required cognitive semantic...

there has been an increasing concern about inactive drivers who would easily lead to road accidents and fatalities once return to driving. this study investigated the re-usability of traffic signs for inactive drivers with consideration of driver factors and cognitive sign features. fifty-seven hong kong chinese, who possessed a full driving license but had not driven for an extended period, co...

Bayesian networks are commonly used in cognitive student modeling and assessment. They typically represent the item-concepts relationships, where items are observable responses to questions or exercises and concepts represent latent traits and skills. Bayesian networks can also represent concepts-concepts and concepts-misconceptions relationships. We explore their use for modeling item-item rel...

Language is a cognitive map of concepts. A cognitive dictionary maps our shared reality as represented by linguistic competence of all speakers. COG offers a systematic description of concepts defined by their language usage. The ‘usage’ is formalized and the paper describes format and rules employed in constructing this new type of lexicographic COG databases. A concept “entry” is a descriptio...

In Cognitive Science, conceptual blending has been proposed as an important cognitive mechanism that facilitates the creation of new concepts and ideas by constrained combination of available knowledge. It thereby provides a possible theoretical foundation for modeling high-level cognitive faculties such as the ability to understand, learn, and create new concepts and theories. Quite often the ...
