Punctuated equilibrium model refers to a group development theory that assumes groups change gradually over time but that the periods of slow growth are punctuated by brief periods of relatively rapid change.

Punctuation is the concept that each person in a transaction believes what he/she says is caused by what the other person says. Basically the individual holds the other responsible for his/her reactions.

This concept is often linked to therapeutic processes or moments of heightened emotional clarity.
