Explanation:
In psychology, the critical period can be defined as the period in which some sort of transformation takes place in a limited time. <u>The critical period is that phase of life which is </u><u>important for the development</u><u> of certain skills psychologically. This period is also necessary for the development of an organism so that it can progress in a normal manner.</u>
It is the period during which the sensitivity of the nervous system is high. The critical period is also known as the optimal or the sensitive period.
So, the correct answer is the last option.
The correct answer is the physical environment
There are several factors that contribute to change and innovation in a society: factors internal to the society itself or external factors of the environment that surrounds it. Nowadays, the extreme importance of the relationship between society and its environment has become very clear. The environment is not only a crucial source for the maintenance of society with its climatic and geographic characteristics in general, its natural wealth, its sources of energy, its flora and fauna, all functioning as a set of conditions in relation to which the society must adapt. In this process, society can interact with its environment in different ways and directions: either contributing to improve or to worsen and impair its living conditions. Changes in the environment end up forcing changes in society. Societies, throughout history, have needed to adjust to changes in the environment. This is an unquestionable adaptation process.
The environment to which a society must adapt also includes other societies with which it maintains contact. A major change in one tends to trigger a chain process with consequences for the others and forcing adjustments and innovations.
But there are other sources of change. The dynamics of forces within societies, which are part of the human condition itself, prevent society from remaining permanently stable. First, in the transmission of cultural heritage from one generation to another, changes of various types occur. As we saw earlier, individuals are not passive in forming habits, learning customs and receiving information as they grow and develop. Human beings are apparently, by their very nature, motivated to try new patterns of action. Motivation is often the simple curiosity that can be intensified by the cultural world. Or, the motivation may be simple material self-interest. Men seek to maximize their rewards, that is, to earn more and better as a result of their actions. In this way, experimentation and innovations are inevitable.
