DEVELOPMENTAL PSYCHOLOGY
1

Developmental psychology stands for a scientific study by which one can understand the reason
and the changing way of human beings over the course of their life. It mostly associated with the
child or infants in respect to study their different life stage including adolescents and adult
development (Gielen and Roopnarine, 2016). The paper keeps its focus on the developmental
psychology through the determination of childhood deprivation effect and their behavioral
aspects with the help of Anisworth and Bowlby’s theory. On the other hand, the study also keeps
its eye on the analysis of different type of case studies (Oxana, Genie and Minnesota twins)
regarding the personality development of child and infant which helps in evaluating Nature Vs
Nature debate. Therefore, it can be understood that the thesis statement of the study is lies on the
analysis of developmental psychology and its significant aspects.
In the context of analyzing developmental psychology, the matter of child deprivation must be
evaluated. The child deprivation means a child who is not getting the proper birth rights and
parental care (Nielsen et al. 2017). Moreover, a deprived child is one who living without proper
parental care along with education and subsistence as per the law which affect negatively on the
mental, emotional and physical health of that child (Kay, 2017). Such kinds of cases are falls
under violation of law in respect to proper parental care. However, the term child deprivation
reflects its negative effect on those children who were not getting proper parental care from their
parents and influence the behavioral aspects along with the psychological thought process of
those children (Nielsen and Haun, 2016). The effect of child deprivation also impacts negatively
on the later development of those children who were far away from proper parental care and
control.
The early deprivation or neglected childhood reflects a psychological impact into the early
adulthood of the children. Most of the research studies proved that he deprived children were
mentally sick due to their disturbed or neglected childhood. On the other side, the different
stages of a child life can affect on their adulthood and adolescent periods differently which
impacts on their interpersonal relationship factors (Lerner, 2020). It is found that the deprivation
during the first 10 years of child’s life effect on their childhood development which leads to the
tendency of depression. Moreover, those children were also unable to adopt any change into their
surroundings and felt difficulties to make adjust with the surroundings (Kline et al. 2018). The
early deprivation also effect negatively on the self controlling power of those children which

results in anxiety and anger and it make those children different from other children. As an
example, a unique study on adopted children from Romanian institution by some UK families
proved that the children who lived in that institution more than 6 months were holds IQ less than
80 whereas the normal children hold IQ of 90 or more than 90 (Science Daily, 2017). It suggests
the developmental delay in early adult hood which impacts negatively on the general cognitive
abilities.
In addition, the play deprivations in early 10 years of children can effects negatively on the
childhood development which also influences the behavioral aspects of those children. A recent
study on play deprivation proved that 71% children are deprived from outside playing due to tha
lacking of place in US and UK which causes poor societal welfare (CHILD AND FAMILY
BLOG, 2020). The study proved that those deprived children were unable to cope up with the
environment and became most coolant in their adulthood which can lead to them into crime.
However, based on the child deprivation and its effect two significant theories can be evaluated
which helps in understanding about the psychological changes within deprived children.
In respect to the theoretical analysis of psychological behavior of a child, there are two
significant works or theories can be evaluated which were associated with attachment. The
attachment theories were represented by two psychologists, John Bowlby and Mary Anisworth.
The psychologists keep their focus on the effect of mother or parent attachment in respect to their
child. The psychologists evaluated that attachment is an enduring and deep emotional bond
which connects one person to another person across space and time (Singer, 2017). The theories
keep their focus on the relationship or bond between parent and child. As per the theory of
Anisworth, the psychologist identified three primary attachment styles in respect to different
child or infant who helps in remaining attached to their mother or parent (McLeod, 2018). On the
other side, the theory of Bowlby suggested that a child would be associated with only one
attachment which acted as a secure base for exploring the world with the help of mother (Heard,
2018).
Bowlby supports the nature of monotropy which means the mother attachment breakdown can
lead to the serious negative consequences on child and made him or her a affectionless
psychopath. Moreover, the psychologist also hypothesized that a child and a mother need to be
closed with each other as per their biological need. The theory also enhanced that the babies
