My principal area of research has been to explore the dynamics of attentional processes in acoustical presentations. This research includes topics such as the detection of signals in time, the basis for developing temporally-based expectations, and the effects of such processes on the effectiveness and efficiency of information processing both for normal populations and for individuals with Attention Deficit Hyperactivity Disorder (ADHD).

I am also interested in auditory perceptual illusions such as spectral motion aftereffects, the tritone paradox, psychology of music, and lateralization of global versus local processing of acoustical stimuli. For more information, check out the links below.

Specific research projects include: a) examining the relative contributions of various cues to rhythm perception and inference of musical meter; b) the importance of harmonic-structure and the timing of harmonic events for inference of musical meter; c) the affects of alcohol consumption on temporal and spatial integration in the auditory system as evidenced through detection and discrimination tasks; d) positive- and negative-priming of frequency- temporal locations; e) spectral motion after-effects and the tritone paradox.
