Why it takes longer to produce discourse under an elaborated code

An elaborated code will arise wherever the culture or subculture emphasizes the 'I' over the 'we'...Meanings which are discrete and local to the speaker must be cut so that they are intelligible to the listener, and this pressure forces upon the speaker to select both among syntactic alternatives and encourages differentiation of vocabulary.

Bernstein, 1971, p. 170.
