Acoustic experience alters the aged auditory system.

Objectives: Presbyacusis, one of the most common ailments of the elderly, is often treated with hearing aids, which serve to reintroduce some or all of those sounds lost to peripheral hearing loss. However, little is known about the underlying changes to the ear and brain as a result of such experience with sound late in life. The present study attempts to model this process by rearing aged CBA mice in an augmented acoustic environment (AAE).

Relational-Interdependent self-construal as a function of bulimic symptomatology.

The present study compares differences in the levels of relational-interdependent self-construal among asymptomatic, symptomatic, and bulimic participants in a natural groups' design. Asymptomatic (n = 169), symptomatic (n = 73), and bulimic (n = 21) participants completed the Questionnaire for Eating Disorder Diagnoses (Q-EDD). Contrast tests were conducted to examine group differences in relational-interdependent self-construal as a function of bulimic symptomatology.
