Abstract
The target article presented a model to stimulate further
research and ultimately, a more definitive theory of the ontogeny
and phylogeny of hierarchically organized sequential activity.
Methodologically, it was intended to stimulate methods for integrating
data from different neuropsychological techniques. This response to
Givon and Swann focuses on several substantive areas: (1) the role
of automaticity in hierarchically organized activity and its neural
substrate, (2) the neural ontogeny of planning, (3) cognitive and
neural architecture for language functions, and (4) the role of
environmental input and interaction in the ontogeny and phylogeny
of language, tools, and brain.
