If they do not experience a moving object during this critical period they will fail to become imprinted at all7.
Is early childhood a critical or sensitive period for language learning quizlet?

What is critical period in growth and development?
Also known as the sensitive period, the critical period is a time during early postnatal life when the development and maturation of functional properties of the brain, its ‘plasticity’, is strongly dependent on experience or environmental influences.How long is the critical period?
Although the critical period for humans varies considerably for specific visual tasks as evidenced in animal studies, the critical period for experience-dependent changes in humans is thought to begin soon after birth (within 6 months or earlier), peak around 1–3 years of age, and decline slowly until 8–10 years of age …

Why language acquisition is a must to take place in a critical period of child's development?
According to the critical period hypothesis, language can be acquired only within a critical period, extending from early infancy until puberty. The hypothesis is untestable for first language acquisition because no child can be intentionally deprived of language for experimental purposes.

What are critical periods in a child's brain development that neuroscientists have identified?
Children’s brains develop in spurts called critical periods. The first occurs around age 2, with a second one occurring during adolescence. At the start of these periods, the number of connections (synapses) between brain cells (neurons) doubles. Two-year-olds have twice as many synapses as adults.
