Concepts and Theories of Human Development

For centuries scientists and philosophers have studied on concepts of child and development. There are mainly three paradigms in development; cognitive, behavior and social aspects of it. When we try to understand how a child acts and what is the meaning of development, first we have to define what is being child? Child is defined as:
1.     Biologically, a child is a human between the stages of birth and puberty. The legal definition of child generally refers to a minor, otherwise known as a person younger than the age of majority.
2.     Child may also describe a relationship with a parent (such as sons and daughters of any age) or, metaphorically, an authority figure, or signify group membership in a clan, tribe, or religion; it can also signify being strongly affected by a specific time, place, or circumstance, as in "a child of nature" or "a child of the Sixties". [1]
So, what can we understand from these dictionary definitions? We can assume that stages of child development are universal. Approximately every child gets through from the same stages averagely in the same age. It is for sure that, a child development depends on nature features like heredity, maturation or genes. However, one thing that we can’t assume is, every child in the same age group will have the same characteristics and same level of maturation. Development also derives from nurture. Environment, experience or learning has great influence on child development. In the second definition of a child, it is directly related with nurture concept. In social learning theory, Albert Bandura (1977) states behavior is learned from the environment through the process of observational learning.  Children observe the people around them behaving in various ways. [2] Likewise, in social learning theory environment has a huge impact on the formation of the child’s evolution.

While child is developing, there is a continuous process of learning. Learning can be defined as persistent change in behavior. Fully comprehending of learning can be ensured by some questions like; ‘Which behavior has changed? , ‘How it changed?’ or ‘Is it a quantitative/qualitative change?’.

However, nature and nurture are not the only aspects that have an influence on development of a child. And all the other perspectives form developmental systems. For example, think about twins. Twins have the same genes and heredity, therefore nature is not a discriminating factor for them. Also, assume that they grow up in the same environment. Then, again nurture can’t be count as the distinctive factor. So, what concept makes twins two different characterized person? In this point Thelen&Smith notion the ‘Dynamic System’. In this system of development, all layers of development interact with each other and individuals self-regulate themselves according to their environment. It is not about the cause and effect relationship, but it is about the individual’ active participation in the evolutionary process. Instead of the Dynamic System, Bronfenbrenner argued that individuals could be affect from the layers of development; eventually they determine the way they develop themselves.

Furthermore, ‘Life-Span’ theory is about life long learning and adaptation of individuals to their environment. Besides, ‘Action Theory’ cares about individuals being active in their social surroundings. Plasticity and ontogeny of individuals are important factor in this theory. Aside from, ‘Life-Course Theory’ sees human development as an interpersonally relational process. The distinctive features of life-course theory are associated with the link that Elder drwas between individual development and the social relationships within which the person’s ontogeny is dynamically collaborative.[3]

In addition to theories of development, many concepts should be considered in order to understand how development occurs and what concepts influence it’s occurrence.
