<em>Inhibited temperament</em>

Inhibited temperament (also referred to as behavioral inhibition or BI) is <em>distinguished by fear, distress, or removal from new circumstances, surroundings, people, or items.
</em>
Kids with behavioral inhibition, <em>when faced with an unfamiliar scenario or person, usually stop their activity and retreat</em>.
When confronted with unfamiliarity, they are watchful of their surroundings and do not approach new items or people on their own.
