Prior knowledge and exemplar frequency.
New concepts can be learned by statistical associations, as well as by relevant existing knowledge. We examined the interaction of these two processes by manipulating exemplar frequency and thematic knowledge and considering their interaction through computational modeling. Exemplar frequency affects category learning, with high-frequency items learned more quickly than low-frequency items, and...
متن کاملExemplar dynamics: Word frequency, lenition and contrast
Over the last decades, a considerable body of evidence has accumulated that speakers have detailed phonetic knowledge of a type which is not readily modelled using the categories and categorical rules of phonological theory. One line of evidence is systematic differences between languages in fine details of pronunciation. For example, it is known that Spanish and English differ systematically i...
متن کاملInterest and Prior Knowledge
This paper selectively reviews research on the relationship between topic interest and prior knowledge, and discusses the optimal association between these variables. The paper points out that interest has a facilitating impact on learning, and at least part of this effect must be ascribed to prior knowledge. While the interest-knowledge association may account for about 20 percent of the varia...
متن کاملExemplar Frequency Affects Unsupervised Learning of Shapes
Exposure to the spatiotemporal statistics of the world is thought to have a profound effect on shaping the response properties of the visual cortex and our visual experience. Here we ask whether subjects’ discrimination performance on a set of parameterized shapes changes as a function of the distribution with which the shapes appear in an unsupervised paradigm. During training, subjects perfor...
متن کاملIntelligence, Prior Knowledge, and Learning
Intelligence test scores can account for achievement differences in many content areas to a considerable extent. An individual’s IQ results from complex interactions between genes and environmental stimulation, foremost schooling. The amount of variance in intelligence to be explained by genes is the higher the more successful a society is in providing cognitively stimulating environments for e...
