We present four case reports of elderly hearing-impaired persons demonstrating a binaural interference effect. Performance measures were poorer when stimulation was binaural than when it was monaural. In the first case the effect is shown for aided speech recognition scores. In the second case it is shown in topographic brain maps of the middle-latency auditory evoked potential. In the third an...

Positive psychology focuses were on the merits of individuals, such as optimism and positive attitude, and the subsequent cultivation of these virtues. Optimism or pessimism is a significant predictor of physical health outcomes. The present study examined whether optimism or pessimism is associated with the loudness dependence of auditory evoked potentials (LDAEP), a biological indicator of se...

INTRODUCTION Stuttering is a speech fluency disorder, and may be associated with neuroaudiological factors linked to central auditory processing, including changes in auditory processing skills and temporal resolution. OBJECTIVE To characterize the temporal processing and long-latency auditory evoked potential in stutterers and to compare them with non-stutterers. METHODS The study included...

Brain-stem auditory potential (BAEP) latencies were measured from individuals with normal or nearly normal hearing. Different age groups were studied separately. Males have 0.1-0.2 msec longer latencies of waves III and V and longer I-V IPLs than females in all age groups. The latencies of waves I, III and V increase 0.1-0.2 msec with increasing age, but the I-V IPL was the same in all age grou...

Human subjects were trained by traditional methods of instrumental conditioning to change the amplitude of a late component of the auditory evoked potential with and without oscilloscopic feedback of their performance.
