Development concept is the process by which an organism transforms positively into a different stage of maturity. The development process may range from physical, social to psychological. Where else, Growth concept represents affirmative positive transformation in both the physical and mental prominence of a particular organism. It is characterized, by the process of noticeable change of an organism by becoming larger, longer and more numerous or more. Most important to note is that growth leads to a physical noticeable change.
Development has a deeper meaning than the term growth in sense that developments does not correlate with overall increase in size of the organism or its parts. For instance, in the early human development, the neurons in the brain develop to critical connections, which result into adult functions such as vision immediately after birth. This can be considered as development but not growth, because you can cannot observe it without using advanced instrument neither des it cause increase of size of anything ( Lawson 2007).
The major domain concepts of development include,
In reference to Allen & Marotz (2010) Physical Development seeks to explore the development of the body structure; development entails the development of sensory nerves, motor neurons and the nervous systems which consist of coordination, perception and movement. Physical development also entails the sensory development of vision, hearing, taste, touch, and smell and the coordination as well as the integration of perceptual input from the environmental systems by the nervous system.
Secondly, Cognitive Development is also part of human development ,it includes intellectual and mental development which involve Activities like thinking, perception, memorizing , reasoning, problem solving ability, abstract thinking and language learning skills. In addition, human development also includes Social Development which involves the child's interactions with others and the child’s involvement in social network (Allen & Marotz, 2010).
Moreover, the Emotional Development is also part of human development and also includes the development of personal traits and characters. The child learns how to use positive words and phrases, eye contact in appropriately and culturally accepted manner and get down to the level of the child by listening respectfully when they speak. Also they acknowledge their efforts and achievements by
Speaking warmly and evaluating their contributions ( Lawson 2007).
An analysis of each developmental milestones and the purpose they serve.
To be more precise any development process proceeds through some stages and each development stage differs. Marotz (2009) argues that, Each stage of development has its characteristics Psychologists .for the purposes of proper analysis of human development human life span is separated into stages and periods and identified specific changes that are expected to occur during each stage. The development from one stage occurs Gradually, this far the major age groups assigned to each stage of the development are, Infancy, early childhood ,later childhood, Adolescence, Young adulthood, mature adulthood and over Aged adulthoods .
Factors that might contribute to atypical development
Ideally, the basic factors which trigger human development and growth range from genetic factors to environmental factors. It is evident that, Genetic factors are responsible for cellular a change which is responsible body development such as the change in proportion of body, brain parts and the maturation aspect such as vision. Environmental factors such as diet and sickness are also known to be a major distrust affecting human development. Other facts contributing to human development include social, emotional and cognitive factors as well (Allen & Marot, 2010).
