Abstract
In 21st century, conduct hereditary research has widened our insight about the starting points of identity contrasts and improvement. By and large, hereditary elements represent over half of the change in precise proportions of identity attributes. In any case, heritability assessments of identity attributes relentlessly decline with age. Hereditary components speak to the essential wellspring of long haul coherence of individual contrasts in identity yet in addition represent change – especially in more youthful ages. Natural variables speak to the essential wellspring of identity change in each time of life, yet additionally add to the moderately high steadiness of identity contrasts all through the grown-up life expectancy.

The Big Five Personality Traits
Today, various psychologists believe that they are five focus personality traits. Affirmation of this speculation has been wrapping up progressively more for quite a while, beginning with the examination of D.
W. Fiske (1949) and progressed upon by various investigators including Norman (1967), Smith (1967), Goldberg (1981), and McCrae and Costa (1987).

Evidence of Genetic Influences on Intelligence
Twin studies suggest that identical twins IQ’s are more similar than those of fraternal twins (Plomin & Spinath, 2004). Siblings reared together in the same home have IQ’s that are more similar than those of adopted children raised together in the same environment (McGue & others, 1993). In addition to inherited characteristics, other biological factors such as maternal age, prenatal exposure to harmful substances and prenatal malnutrition may also influence intelligence.
Evidence of Environmental Influences on Intelligence
Identical twins reared apart have IQ’s that are less similar than identical twins reared in the same environment (McGue & others, 1993). School attendance has an impact on IQ scores (Ceci, 2001). Children who are breastfed during the first three to five months of life score higher on IQ tests at age 6 than same-age children who were not breastfed (Kramer & others, 2008).
First Born Children
Factors such as family, education, enriched social environments, and peer groups have all been linked to differences in IQ. For example, studies have found that first-born children tend to have higher IQs than later-born siblings. Many experts believe that this is because first-born children receive more attention from parents. Research also suggests that parents expect older children to perform better on a variety of tasks, whereas later-born siblings face lesser task-focused expectations.
Biological and social development
The role of biological maturity in behaviors in adolescence which most often are considered as negative by adults was investigated for a normal group of girls. In mid-adolescence early matured girls were found to play truant, smoke hashish, get drunk, pilfer, ignore parents” prohibitions, considerably more often than did late maturing girls. These differences between biological age groups were mediated by the association with older peer groups and they leveled out in late adolescence. Data on alcohol consumption and crime at adult age showed little association with biological maturation. A hypothesis was tested suggesting that early biological maturation may have negative long-term consequences within the education domain. In accord with this assumption, a considerably smaller percentage of girls among the early matures had a theoretical education above the obligatory nine-year compulsory schooling than among the late maturing girls.
Book Review The Art and Science of Personality Development
A few outstanding subjects go through the book. One subject is that identity is a developmental accomplishment; it is an individual’s “characteristic variation on the evolved design for human nature” (p. 4). In addition, for McAdams, “It makes consummate evolutionary sense that a eusocial species like ours would evolve to take careful note of variations in personality” (p. 39). The transformative plan incorporates a grip of shared purposefulness, the likelihood of complementary charitableness, the need to have a place, structure connections, and deal with the necessities and dangers to assemble solidarity. Identity helps sort this out. We have to see who is caring, loyal, persevering, conscientious, and pleasing, among numerous different attributes, so as to make sociality work for transformative achievement. “Personality begins with the different reputations that human actors achieve as they strive to get along and get ahead in social groups” [Mc-Adams, 2015, p. 41]. The human species has developed to see these distinctions. A second subject is that trademark minor departure from the developed general structure for human instinct, that is, one’s identity is an “artful experiment.” Indeed, the title of the book is no insignificant explanatory prosper. McAdams truly views the creation and of identity as an innovative exhibition in the social field. The craft of identity improvement includes, in addition to other things, “the expression and refinement of a uniquely personal and recognizable style of emotional performance” (p. 44).
Conclusion
The developmental study of individual differences in personality provides a rich source of data for the researcher and practitioner alike to use in understanding and predicting behavior. Without the study of individual differences, there could be no detailed analysis or explanation of why people often behave or develop very differently under seemingly equivalent environmental conditions. Understanding these differences and the development of these differences is fundamental not only to psychologists’ understanding of behavior but also to parents, schoolteachers, , policymakers, and anyone else working with other people. Because of its universality and its implications for understanding behavior, the study of individual differences is an essential part of any complete scientific study of behavior.
