Can recovering alcoholics help hospitalized patients with alcohol problems?

Objective: The researchers evaluated the relative effectiveness of 2 interventions for patients with alcohol problems.

Study Design: A nonrandomized intervention study was used to compare usual care (control) with a 5- to 15-minute physician-delivered message (brief intervention) and with the physician message plus a 30- to 60-minute visit by a recovering alcoholic (peer intervention). Telephone follow-up was obtained up to 12 months after hospital discharge that focused on patient behaviors during the first 6 months following discharge.

Contribution of listeners' approaching motion to auditory distance perception.

Of the several sources of acoustic information for distance perception, those arising from motion of the listener or sound source have received little attention. This motion-related information (recently called acoustic tau) is described, and experiments evaluating its utilization are presented. Accuracy and consistency at walking to the locations of briefly presented sounds were better when people listened while walking than while standing still.
