Positive in that the infant’s brain is open to learning new things and acquiring new skills as well as enriching influences. However, the young brain is prone to developmental problems especially when the environment is un-nurturing or impoverished. Research shows that the environment of an infant’s early years can have effects affecting the infant throughout life.
Muehlenbein, (2010) further says that due to advanced technology, effects relating to early brain development and the environment are now easier to study and understand. Patterns in brain activity that seem to be related to some types of negative early experiences can now be identified by neuroscientists. However, some scholars argue that even before the brain scanning tools allowing this study, some behaviors stemming from early stress, poverty, maltreatment and neglect could be seen even before technology.
The evidence provided by neuroscientists is of essence and should be paid attention to since it is crucial in helping people understand how exactly the environment affects brain development. Such knowledge will help children who are at risk and to reverse where possible the consequences of early adversity. Neuroscientists may also aid in our efforts to learn when experiences affect children. Understanding the patterns of specific periods of vulnerability is a better way of improving efforts towards intervention.
Brain development begins in the first three weeks after a child is conceived. At conception, it is the egg and the sperm that meet forming a single cell that determine the potential of the genes. Over 55% of the genes carry out the work of brain development. Cells in a thin layer develop on the embryo (Brestan & Lee, 2009). The cells merge to form a tube filled with liquid which is the foundation of the brain and the spinal cord. At this stage, the embryo produces neurons also called nerve cells and in the first month, the cells multiply to produce

There is much debate centered on the appropriate time in a person’s life of when to begin learning a second language. Neuroscience perhaps is the best field to resolve this debate. Through the use of neuroimaging techniques, neuroscientists have the ability to identify the structures of the brain involved in primary and second language acquisition.
With some of these studies taking shape and showing some considerable truth, specific developmental domain like social, emotional, physical and developmental period like that of infancy are now understood and easily analyzed. However, it is arguably true that the way a human being develops from infancy to adulthood involves both internal and external factors.
One such theory was regarding the theory of formation of new cells in mammalian brain. Till as late as 1980s, it was firmly believed that neurogenesis is restricted to the gestation period, and formation of no new cells takes place in adult mammalian brain.
Children use more brain than adults. In the journal Cerebral Cortex, the team said that the alterations in the activity of regional brain from infancy to teenage shows increased efficiency of the mature brains.
Living organisms always develop but the amount of change can either be easily noticed or not realized throughout the lifespan (Santrock, 2006). Moreover, development has been found to be linked (but not reliant) to age and as one gets older in age, then the rate of development can either be fast or slow.
3). This paper joins in the plethora of writers and attempts to define self-esteem as a trait and follows its development throughout the lifespan of individuals. Researchers and practitioners in their attempt to define self-esteem have unearthed a number of components to this one trait.
In this similar context, these changes are mostly identified in terms of emotional, physical, sociological and psychological attributes possessed by an individual. Various Developmental Changes that Occur in Each Stages of Life Physical Developmental Changes For any individual, physical activities relating to physical changes can be considered as a necessary component for maintaining a healthy life.
By the 17th - 20th day of gestation, the primitive embryo grows as the neural plate, which is a sheet of cells that finally develop into the nervous system of a man. The spinal cord is developed during third and fourth weeks. The cerebral hemispheres separate in the fifth week.
The infant is an actively dynamic being characterized with constant and gradual sequence of changes in development of the neuro-system as well as the physical growth. Internal and external forces, in a way, influence growth of every individual and produces differences
