Answer 1

Critical period

Step-by-step explanation:

The critical period in developmental psychology is the stage of the maturation stage. This is a critical period. In this period the stimuli do not get the information from the environment. This is a very sensitive period. In this period, there are two stages:

• The weak period
• The strong period

The strong period is more sensitive to the environment. Thus here Dr. MecGiver believes that this developmental stage is a critical period.
