Categories are fundamental to everyday life and the ability to learn new categories is relevant across the lifespan. Categories are ubiquitous across modalities, supporting complex processes such as object recognition and speech perception. Prior work has proposed that different categories may engage learning systems with unique developmental…

Diversified emotional responses are generally referred as the evidence of showing categorical perception of major and minor modes. Yet it is uncertain whether the categorical performance is independent to the emotion tagging. This study therefore adopted a direct measure with the proper controlled stimuli to reexamine the categorial nature of…

Purpose: Age-related sensorineural hearing loss can dramatically affect speech recognition performance due to reduced audibility and suprathreshold distortion of spectrotemporal information. Normal aging produces changes within the central auditory system that impose further distortions. The goal of this study was to characterize the effects of…

Children interact with and learn about all types of sound sources, including dogs, bells, trains, and human beings. Although it is clear that knowledge of semantic categories for everyday sights and sounds develops during childhood, there are very few studies examining how children use this knowledge to make sense of auditory scenes. We used a…

This study investigated the developmental trajectories of three perceptual domains related to regional dialect competence: the linguistic domain, tested through an intelligibility in noise task; the objective indexical domain, tested through locality judgments and a free classification task; and the subjective indexical domain, tested through…

A pupil's ability to identify common organisms is necessary for acquiring further knowledge of biology. We investigated how pupils were able to identify 25 bird species following their song, growth habits, or both features presented simultaneously. Just about 19% of birds were successfully identified by song, about 39% by growth habit, and 45% of…

Development of the relation between skills of visual and auditory pattern classification was studied at the second grade, sixth grade, and adult age levels using visual and auditory representations of the same abstract information. Results showed evidence of common processing of pattern class structure for the modalities, patterns, prototypes, and…

Development of the ability to classify auditory patterns was studied at grades 2, 6, 10, and 12 and at adult age levels. Both accuracy and feature use in classification were consistent across age; the age changes that did occur appeared to be due to differences in perception rather than process. (JMB)

Speech perception outcomes in young children with cochlear implants are affected by a number of variables including the age of implantation, duration of implantation, mode of communication, and the presence of a developmental delay or additional disability. The aim of this study is to examine the association between degree of developmental delay…
