What is the critical period in brain development?

What are critical periods for brain development Why are these periods important?

A critical period is a developmental stage during which the nervous system is especially sensitive to environmental stimuli. If, during this period, the organism does not receive the appropriate stimuli required to develop a given function, it may be difficult or even impossible to develop that function later in life.

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.

What are critical and sensitive periods of development?

Sensitive periods generally refer to a limited time window in development during which the effects of experience on the brain are unusually strong, whereas a critical period is defined as a special class of sensitive periods where behaviors and their neural substrates do not develop normally if appropriate stimulation …

What is an example of critical period?

The term “critical period” is also used to describe physiological as well as behavioral phenomena. For example, the embryonic stage in humans is a critical period for certain types of growth (such as the appearance of the heart, eyes, ears, hands, and feet) which must occur for prenatal development to proceed normally.

What is critical period in psychology examples?

For example, the critical period for the development of a human child’s binocular vision is thought to be between three and eight months, with sensitivity to damage extending up to at least three years of age. Further critical periods have been identified for the development of hearing and the vestibular system.

Critical periods have identifiable starting and ending times, thereby tending to begin and end suddenly, rather than gradually(if at all.)

What is sensitive period in psychology?

What is the development of the brain?

Brain development is an aspect of neural development and comprises the processes that generate, shape, and reshape the brain itself, from the earliest stages of embryogenesis to the final years of life. The study of brain development aims to describe the anatomical development of the brain and to address the underlying mechanisms.
