Auditory sensitivity in preschool children.

چکیده
Thresholds for octave-band noises with center frequencies of 0.4, 1, 2, 4, and 10 kHz, and 1/3-octave-band noises with center frequencies of 10 and 20 kHz, were obtained from children 3-5 years of age and from a comparison group of adults. Thresholds for all frequencies decreased between 3 and 5 years of age. Thresholds decreased further between 5 years of age and adulthood, except for the 20-kHz stimulus, for which children had lower thresholds than adults. These results are discussed in terms of possible age-related changes in the mechanical properties of the ear and in the efficiency of neural coding.

متن کاملCoherent motion detection in preschool children at family risk for dyslexia
We tested sensitivity to coherent motion (CM) in random dot kinematograms in a group of 5-year-old preschool children genetically at risk for dyslexia, compared to a group of well-matched control children. No significant differences were observed, either in a group analysis or in an individual deviance analysis. Nonetheless, CM-thresholds were significantly related to emerging orthographic skil...
متن کاملHyperglycemia and Red Cell Distribution Width for Prediction of Mortality in Preschool Children with Community Acquired Pneumonia (CAP)
Background Community acquired pneumonia (CAP) is a major infectious cause of mortality in preschool children especially in developing countries. Red Cell Distribution Width (RDW) has been associated with poor outcomes of CAP. We aimed to determine whether admission stress hyperglycemia and RDW can predict mortality in preschool children with CAP for early identification of patients at risk of ...

Background : Body mass index (BMI) is one of the most popular anthropometric techniques to identify obesity. The purpose of this study was to evaluate the sensitivity and specificity of BMI percentiles of Center of Disease Control (CDC2000) in determining obesity in preschool children in comparison to real obesity ( based on body fat index FMI) and compare the status of overweight and obesity...
متن کاملAuditory-Visual Speech Perception in School and Preschool Children
The development of auditory-visual speech perception was investigated in pre-school children, school children and adults. Results show a link between auditory-visual speech perception and language-specific speech perception in school children. In addition it was found that speechreading ability in early childhood was predicted by cognitive abilities. Additionally, adults’ and preschool children...
