Research interests

The primary focus of my work is problem of time and temporal patterns. Temporal patterns are a major problem for cognitive science since conventional symbolic models deal naturally only with static systems or with patterns specifiable in absolute durations (like milliseconds). Thus my research focuses on auditory pattern perception, speech and linguistics. I have addressed such topics as the temporal structure of words and phrases in English, Japanese, German, Arabic, etc. I am convinced that only models based on dynamical systems offer the right properties for handling time in a way that will be useful for an animal living in a physical world. Some kinds of connectionist models and other models based on differential equations have the right kind of dynamical properties. This work is compatible with a view of general cognition that is based on dynamical systems theory rather than symbol-based computational models.

Facilities

The Auditory Cognition Laboratory has a wide variety of equipment for synthesis and processing acoustic signals. In addition to appropriate audio equipment (tape players, DAT, amplifiers, speakers, headphones, etc), the laboratory also has a number of SUN and Silicon Graphics workstations with software for sound synthesis and acoustic analysis of speech and other audio signals.
