The mechanism by which is micro-aggression delivered may go in several ways: interactional (verbal, nonverbal), behavioural or in environmental form.
Verbal and non-verbal micro-aggressions are purposeful and deliberate communications that are meant to cause long-term debilitating and depressing effects in the victim.
Example of verbal micro-aggression is saying: “You are so smart for a girl.”
On the other hand, non-verbal micro-aggression could be rolling eyes only when woman co-worker speaks during meeting.
