Section II - Critical Periods in Human Development

We (humans) have all sorts of critical periods. Describe a critical period and explain why your example is an example of a critical period in human development.

As always, your subject line should identify the critical period you are discussing - and it should not duplicate anyone else's share.

Are there critical periods throughout life?

Examples need to be about human development. IF there are animal studies to support that human critical period, they can be shared - but the focus is on we humans.
