Answer:
Sensitive Period
Explanation:
Sensitive Period is a period or a stage of developmental changes in which an organism is vulnerable to precise and certain kinds of stimuli in their environment. At this stage, it is easier and quicker to learn particular skills and to acquire certain abilities. When those stimuli that triggered such learning skill and abilities are absent, the learned skills does not deteriorate. We can therefore conclude that, the absence of those stimuli does not always produce irreversible consequences.
