ATTENTION OF HEALTHY AND HYPERACTIVE PRESCHOOL CHILDREN-ELECTRODERMAL ACTIVITY DURING AUDITORY STIMULA TION

Comparing auditory sustained attention in children with auditory processing disorder and normal children

Introduction: Auditory processing disorder (APD) is a type of abnormal perceptual processing of auditory information within the central auditory nervous system that could be influenced by cognitive factors, such as attention. Attention is one of most important cognitive functions in the development of learning in children, so it is important to recognize and evaluate a variety of attention defi...

Auditory sensitivity in preschool children.

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-k...

Effects of methylphenidate (Ritalin) on selective attention in hyperactive children.

This study investigated the effect of methylphenidate (Ritalin) on the selective attention of hyperactive children designated as favorable or adverse responders to stimulant medication. Using a type II incidental learning paradigm, it was found that children in the drug condition recalled more central and less incidental stimuli than those children in the placebo condition. While no differentia...

Brain development in healthy, hyperactive, and psychotic children.

S erious and chronic childhood psychiatric disorders have long been assumed to reflect relatively subtle abnormalities of brain development. Although diagnostic brain imaging is well established in pediatric neurology, it has not yet permitted quantitative assessment of brain abnormalities in children with psychiatric illnesses. Recent advances in brain magnetic resonance imaging (MRI) allow re...
