The critical period hypothesis (CPH) states that the first few years of life constitute the time during which language develops readily and after which (sometime between age 5 and puberty) language acquisition is much more difficult and ultimately less successful.

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.
What is the critical period? 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.
The best known example of a critical period in animal development is that young ducks will become imprinted on any moving object in their immediate environment at approximately 15 h after hatching. If they do not experience a moving object during this critical period they will fail to become imprinted at all7.
Parent Tip. Recent brain research indicates that birth to age three are the most important years in a child’s development.
A 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.
The term Critical Period, coined by John Fiske (philosopher) in 1888 with his book ‘The Critical Period of American History’, refers to the 1780s, a time right after the American Revolution where the future of the newly formed nation was in the balance.
A critical period is a time during an organism’s life span when it is more sensitive to environmental influences or stimulation than at other times during its life.
Accordingly, adolescence is considered as a crucial stage in human life that needs utmost parental care, guidance, and empathy.
Bowlby concluded that all children need to have a warm, intimate and continuous relationship with their mother or a permanent mother substitute. Moreover he believed that there is a critical period for this relationship to develop, from 6 to 30 months.
According to Bowlby, there are four phases of attachment during infancy: preattachment phase, attachment-in-making phase, clear-cut attachment phase, and formations of reciprocal relationships phase.
While there are no specific critical periods for instinctual growth in human development such as with the gosslings, children need critical moments to attach with parents.
For example, the first 3 days of life are thought to constitute a critical period for imprinting in ducks, and there may be a critical period for language acquisition in human infants.
Examples of putative critical/sensitive periods in biobehavioral development include the establishment of social and food preferences (imprinting), shaping the structure and function of sensory systems, and possibly the area of language and language acquisition.
What is Critical Period. A critical period is a phase during which the brain cell connections are more plastic and receptive to the influence of a certain kind of life experience. These connections, called synapses, can form or strengthen more easily during this period.
In the first five years of life, experiences and relationships stimulate children’s development, creating millions of connections in their brains. In fact children’s brains develop connections faster in the first five years than at any other time in their lives.
Children are more likely to experience abuse and neglect during their first three years of life than at any other age. Because a child’s developing brain is most flexible during the earliest months and years of life, this time period sets the foundation for lifelong health and wellbeing.
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 …
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.
This is a crucial time in a child’s development because this period lays the foundations for the child’s learning and well-being throughout their life. It is therefore considered to be the most important phase of development in life, that which shapes the adults and consequently the society of tomorrow.
More specifically, the “Critical Period” refers to the period of time following the end of the American Revolutionary War in 1783 to the inauguration of George Washington as President in 1789. During this time, the newly independent former colonies were beset with a wide array of foreign and domestic problems.
Chomsky (1969) asserts that environmental factors must be relatively unimportant for language emergence, as so many different factors surround children acquiring L1. Instead, Chomsky claims language learners possess innate principles building a ‘language acquisition device’ (LAD) in the brain.
The Critical Period
New state governments were established in most states, expanding voting and officeholding rights. Lawmakers let citizens decide which churches to support with their tax monies. Several states adopted bills of rights guaranteeing freedom of speech, assembly, and the press, as well as trial by jury.
Sensitive periods are periods of psychological development in the child. This period is a time of limited duration. During the sensitive periods, the child has very powerful capacities. The child is able to do great things and make very important acquisitions, like language and movement.
The term `critical period’ is sometimes used when there is an abrupt decline in plasticity and no residual plasticity after this period is over, whereas the term `sensitive period’ is used when there is a more gradual decline and some (reduced) plasticity remaining throughout life.
The difference between critical periods and sensitive periods is subtle. Theorists who believe in critical periods believe that children who do not get special stimulation during their window of receptivity are going to be “stuck” forever and never gain the abilities they should have gained in that period.
In developmental psychology and developmental biology, a critical period is a maturational stage in the lifespan of an organism during which the nervous system is especially sensitive to certain environmental stimuli.
The most important phase of life is the first few years when you are a child. That’s when the brain grows really fast – faster than any other time in our life. The brain makes [more than 1 million] new connections every second!
Bowlby suggested that there was a sensitive period for the formation of the attachment relationship. This period is from approximately six months to twenty-four months of age and coincides with the infant’s increasing tendency to approach familiar caregivers and to be wary of unfamiliar adults.
For example, Schaffer and Emerson suggested that attachments develop in four stages: asocial stage or pre-attachment (first few weeks), indiscriminate attachment (approximately 6 weeks to 7 months), specific attachment or discriminate attachment (approximately 7-9 months) and multiple attachment (approximately 10 …
Of the four patterns of attachment (secure, avoidant, resistant and disorganized), disorganized attachment in infancy and early childhood is recognized as a powerful predictor for serious psychopathology and maladjustment in children (2,18–24).
