Consider first the nature of primary linguistic data. This consists of a finite amount of information about sentences, which, furthermore, must be rather restricted in scope, considering the time limitations that are in effect, and fairly degenerate in quality (cf. note 1 4). For example, certain signals might be…

Once a newborn neuron has migrated, planting its cell body in a permanent position, it sends out a fine axon shoot with an enlarged tip known as a growth cone. At the end of the growth cone are about a dozen long tentacles that shoot out in all directions and act like…

At the time, the field of psychology was dominated by the theory of "behaviorism," which proposed that all our actions, from the simplest smile to the most sophisticated chess move, are learned…
