ABSTRACT
Oscillators and entrainment are just as much a part of the Basic Auditory Toolkit of cognition as they are of the Basic Motor Control Toolkit. The kinds of rhythm that are found in human languages may reflect either audition or motor control, or both. And it may be hard to tell which is the primary source. Language is both motor and perceptual, yet, fundamentally, neither. Language is an abstract, medium-independent structure – a system that is shared to varying degrees by members of a speech community. All of this is what is meant by saying that language is a cognitive system (van Gelder and Port, 1995).
