Psychology
In the context Attachment theory, the relationship between the parents and children and how it influence the development of children. This is the most theory of explaining the development of children since the children tend to develop attachment to their caregivers in the social set up. This attachment theory tend to be the most important due to the fact that it involves the study of several disciplines relating to the lives of human beings like evolution, psychology and ethological theory. This theory is well explained by the nature of homeless children and orphans who lack attachment to specific individuals making them very aggressive in life due to the difficulties they face. This theory shows how children develop depending on when attached to individuals who raise them up thereby influencing their characters and behaviors due to the social interaction. Caregivers therefore have a major impact on the children they raise as a result of the social interaction between the child and caregiver.
On the other hand, the object permanence assumes that the object may even exist at circumstances where they cannot be observed physically. This theory of child development is considered of less importance due the fact it lacks scientific support. It is contradicting due to the fact some people think that it is acquired at early childhood stages while others believe that the objects are innate. This theory is often challenged by the experimental evidence on infant studies that children can identify the objects at their early age as shown by their reaction towards such objects. This theory is also faced with challenges like the capability of children with disabilities to demonstrate the permanence of objects. Disagreement also arose relating to levels of difficulty posed by the different positions of the objects. This theory is therefore considered less effective due to the challenges it faces.
