John Bowlby He developed the concept of a ‘theory of attachment’, suggesting that we are born pre-programmed to form attachments to others, as without this babies could not survive.

What is Lenneberg critical period hypothesis?

Lenneberg argued that language acquisition needed to take place between age two and puberty – a period which he believed to coincide with the lateralisation process of the brain. (More recent neurological research suggests that different time frames exist for the lateralisation process of different language functions.

What happens during the critical period?

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.

What is a critical period in early brain development?

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 a sensitive period during development?

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.

A good example of a sensitive period is a time when: children learn language easily. In Bronfenbrenner’s ecological-systems approach, the _______refers to interaction among the systems.

What is the most critical time period for brain development?

One of the main reasons is how fast the brain grows starting before birth and continuing into early childhood. Although the brain continues to develop and change into adulthood, the first 8 years can build a foundation for future learning, health and life success.

What is the difference between a critical period and a sensitive period?

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 …

Is there a critical period for attachment?

This theory also suggests that there is a critical period for developing an attachment (about 0 -5 years). If an attachment has not developed during this period, then the child will suffer from irreversible developmental consequences, such as reduced intelligence and increased aggression.
