The ability to categorize is a ubiquitous property of human cognition. However, despite much progress in understanding how children learn to categorize, several important issues remain highly debated. The central issues in this debate concern the role of perceptual input and the role of linguistic labels in categorization and category learning. This chapter reviews recent evidence bearing on th...

A speaker's regional dialect is a rich source of information about that person. Two studies examined five- to six-year-old children's perception of regional dialect: Can they perceive differences among dialects? Have they made meaningful social connections to specific dialects? Experiment 1 asked children to categorize speakers into groups based on their accent; Experiment 2 asked them to match...

Data mining methodology has a tremendous contribution for researchers to extract the hidden knowledge and information which have been inherited in the data used by researchers. It is a processing procedure of extracting credible, novel, effective and understandable patterns from database. This paper is used to categorize the students into grade order in all their education studies and it helps ...

In daily life environmental sounds that are present around us include intricately mixed sounds emitted from different sources. This work aim is to contribute a method for sound source separation by means of the enhanced k-means clustering with adaptive genetic algorithm. At first removes the features from the input audio signal by means of Mel Frequency Cepstral Coefficients (MFCC) and spectral...

The degree to which overextension effects found with conjunctions of semantic categories, such as sports and games (J. A. Hampton, 1988), would generalize to categories of visual stimuli was tested in 4 experiments. Overextension occurs when participants categorize a stimulus in the conjunction of 2 categories but fail to categorize the same stimulus as belonging to 1 of the 2 constituent categ...

Learning to categorize objects is known to have systematic effects on how those objects are judged (e.g., similarity or same-different judgments). These so-called learned categorical perception (CP) effects have been demonstrated with a wide variety of stimuli, particularly visual stimuli. However, it does not appear that they have ever been explored with visual motion features that are arguabl...

It has been demonstrated that when people free classify stimuli presented simultaneously in an array, they have a preference to categorize by a single dimension. However, when people are encouraged to categorize items sequentially, they sort by "family resemblance," grouping by overall similarity. The present studies extended this research, producing 3 main findings. First, the sequential proce...

This paper presents Document Categorizer Agent that categorizes computer science academic papers in .pdf format such as journals and proceedings. In this paper, we propose the use of set of term stored in a database to categorize computer science papers. Few methods and algorithms from related work are considered in improving the categorization process. We have evaluated our document categorize...

Faces are rich in social information; they easily give away a person's sex, approximate age, feelings, or focus of attention. Past research has mostly focused on investigating the distinct facial signals and perceptual mechanisms that allow us to categorize faces on these individual dimensions. It is less well understood how the different kinds of facial information interact. Here we investigat...

The ability to discriminate visually based on race emerges early in infancy: 3-month-olds can perceptually differentiate faces by race and 6-month-olds can perceptually categorize faces by race. Between ages 6 and 8 years, children can sort others into racial groups. But to what extent are these abilities influenced by context? In this article, we review studies on children's racial categorizat...
