OBJECTIVE Behavioral, electrophysiological, and imaging studies have found evidence that anxiety disorders are associated with left hemisphere dysfunction or higher than normal activation of right hemisphere regions. Few studies, however, have examined hemispheric asymmetries of function in social phobia, and the influence of comorbidity with depressive disorders is unknown. The present study u...

This article presents an overview of our studies in elderly and Alzheimer patients employing Kimura's dichotic digits paradigm as a measure for left hemispheric predominance for processing language stimuli. In addition to structural brain mechanisms, we demonstrated that attention modulates the direction and degree of ear asymmetry in dichotic listening. Elderly showed increasingly more difficu...

The notion of speech prosody dates back to MonradKrohn's (1947) case study of a woman who was unable to produce the phonemic tone contrasts in her native Norwegian dialect, even though she retained considerable musical ability. Languages that exploit phonologically relevant variations in pitch a t the syllable level are called tone languages (for review of the phonetics of tone languages, see G...

The controlled attention theory of working memory suggests that individuals with greater working memory capacity (WMC) are better able to control or focus their attention than individuals with lesser WMC. This relationship has been observed in a number of selective attention paradigms including a dichotic listening task (Conway, Cowan, & Bunting, 2001) in which participants were required to sha...

Unilateral temporal lobe ablations have become a common treatment procedure for intractable epilepsy. Five children, ranging in age from 11 to 16 years, received a battery of tests to evaluate possible postoperative changes in central auditory processing functions. Children were tested before surgery and at 1 year following surgery. Tests included the SCAN test for central auditory processing, ...
