A. True

b. False: the communication pattern that jack gibb called, "spontaneity," is essentially honesty, openness, and transparency.

Answer: a. True

Explanation:

Jack Gibb defined aspects of communication that come off as supportive or defensive. Supportive communication has an underlying tone of encouragement. In Defensive communication, one of the parties involved feels threatened. Each of these groups has 6 behaviors.

Spontaneity is one of the defining behaviours of supportive communication, along with Description, Problem Orientation, Empathy, Equality and Provisionalism. Spontaneity here means being straightforward, direct and honest. It uses a reliable, authentic and transparent form of conversation.
