The effects of rise time and center frequency on the auditory brainstem response (ABR) elicited by high-frequency tone bursts were examined in six normal-hearing adults. Tone bursts with rise times of 0.1, 0.25, 0.5, and 1.0 msec, duration of 2 msec, and center frequencies of 8, 10, and 12 kHz were used in this study. The absolute latencies of waves I, III, and V were obtained in all subjects, ...

This study evaluated the effects of stimulus repetition rate, phase, and frequency on the auditory brainstem response (ABR) in normal-hearing neonates and adults. In both neonates and adults, the results clearly showed large ABR wave V latency differences between condensation and rarefaction for low-frequency stimuli. Phase dependent latency effects are believed to be a result of the phase-sens...

In order to elucidate why many elderly listeners have difficulty understanding speech under reverberation, we investigated the relationship between word intelligibility and auditory brainstem responses (ABRs) in 28 elderly listeners. We hypothesized that the elderly listeners with low word intelligibility scores under reverberation would show degraded subcortical encoding information of reverbe...

Traditionally the study of fish hearing is achieved either by psychophysical method (e.g., behavioral training) or invasive electrophysiological recording (e.g., microphonics, single unit recording). A non-invasive, the auditory brainstem response (ABR) recording method is developed to study fish hearing. With the use of the ABR method and the removal of gas from various gas holding structures,...

In the face of the ever-growing popularity of social media, psychologists continually encounter new dilemmas regarding our ethical and professional principles. Negotiating the balance between the intrinsically public nature of social media participation and the highly private nature of the therapeutic relationship can be a challenge. Psychologists working with children and adolescents are of pa...

OBJECTIVE To determine the extent to which practicing veterinarians in King County, Washington, engaged in commonly recommended practices for the prevention of zoonotic diseases. DESIGN Cross-sectional survey. Sample Population-Licensed veterinarians practicing clinical medicine in King County, Washington. PROCEDURES A survey was sent between September and November 2006 to 454 licensed vete...

The governing bodies for psychiatry, psychology, and social work all publicly support culturally competent mental health care and have called for increased awareness of the importance of racial, ethnic, and cultural identity in mental health treatment and outcomes. However, since 1960 the population of people identifying as American Indian in the United States has grown faster than can be expla...

Private information retrieval (PIR) is a way for clients to query a remote database without the database holder learning the clients’ query terms or the responses they generate. Compelling applications for PIR are abound in the cryptographic and privacy research literature, yet existing PIR techniques are notoriously inefficient. Consequently, no such PIRbased application to date has seen real-...
