A time when a certain type of development is most likely to happen and happens most easily is called:

_____ Period

Thank you in advance for the help! (:

It's a cross word puzzle and I have no hints. I was thinking it is a period where children undergo development. I am unsure what the period is called though.

The term you are looking for is "Critical Period." In developmental psychology, a critical period refers to a specific time frame during an organism's development when it is particularly sensitive to certain experiences. During this window of opportunity, specific skills, behaviors, or abilities are more easily acquired or developed. This concept was first introduced by the biologist Konrad Lorenz and has since been extensively studied in various areas of development, such as language acquisition, sensory perception, and socialization. To find this answer, you can search for "developmental psychology critical period."

There's no way to tell from this.

If you list what your text indicates (maybe a list of periods) and indicate what YOU THINK the answer is, a tutor may be able to help.
