Attention Effects On Distortion Product Otoacoustic Emissions With Contralateral Speech Stimuli, Genaya Kae Timpe

College of Education and Human Sciences: Dissertations, Theses, and Student Research

The purpose of the present study was to investigate the effect of attending to a speech stimulus on the amplitude of the distortion product otoacoustic emission (DPOAE). The distortion product otoacoustic emission is a measurement of the activity of the inner ear, specifically the outer hair cells in the ear. The activity of the outer hair cells depends upon the auditory nervous system; when it is stimulated, the outer hair cell activity is modified. Normal outer hair cells will create a large DPOAE amplitude. When a stimulus is presented to the opposite ear, the auditory nervous system acts upon the …

Asperger's Syndrome : A Review Of Literature, Tracy L. Gappa

Graduate Research Papers

This paper contains a review of literature on Asperger's Syndrome (AS). This disorder is characterized by deficits in social interaction skills and communication skills (such as the absence of eye contact or facial expressions). Individuals with AS also insist on routines in behaviors, and pursue a relatively narrow range of interests and activities. Etiology is thought to be multifactoral. Studies have indicated that AS may be influenced by genetic factors as well as pre-, peri-, and postnatal trauma. The disorder is also more common among boys than girls.

In this paper, the general clinical features of AS are reviewed, with …
