Sociolinguistics 4, Exercise 3: convergence and divergence

Convergence: shifting speech patterns to more closely resemble a partner's.
Divergence: accentuating the differences between you and another person.

Welsh speakers who strengthened their accents and used Welsh when their
identity was threatened: divergence. Motive: intergroup distinctiveness
(speech can signal a salient group distinctiveness to reinforce a social
identity).

A native French speaker using complex terms with a novice: the source
describes this as creating distance (divergence). Matching a motive is my
judgment: the closest is causal attribution, since the novice will judge
the speaker's intent from the choice. The source does not link this
example to a named motive.
