Answer:
Emotional autonomy
Step-by-step explanation:
Emotional autonomy is a term that refers to the ability to have significant control over one's life and to be able to take decisions and relinquish the interpersonal dependency on others.
This term also refers to the affective disengagement of the adolescent from his or her parents that makes him/her spend more time with friends.
In this example, Peter is noticing changes in the expression of affection and distribution of power in relation with his parents. He is less likely to rush to them with a problem and is spending more time with friends.
We can observe that Peter is starting to have control over his own life and he's taking decisions by himself (instead of rushing to his parents with a problem), thus this is an example of Emotional autonomy that Peter is developing.
