In developmental psychology, age is the most examined variable. Examining chronological age in developmental psychology is informed by the fact that the performance of tasks is associated with age whereby, for example, teenagers will perform at higher levels compared to younger children (Flaherty, 2010). However, psychology professionals also note that development is not caused by age because age is simply a reflection of the fact that an individual has been in existence for a given amount of age (Keijsers & Poulin, 2013). More specifically, chronological age as used in developmental psychology conveniently takes the place of other developmental processes that have not been …show more content…
For instance, psychological methodologies will not appropriately apply sociological factors but human development will only be understood when studied in the contest of sociology, computer science, linguistics and anthropology (Hepach, Vaish & Tomasello (2013). In terms of the contextual and historical nature of development, the researchers acknowledge that there are discrepancies in development across the varying contexts in which people live. Rural and social settings, as explained by Tilton-Weaver (2014), impact differently on development compared to urban settings because of the unique sets of factors associated with them. While Flaherty (2010) and Keijsers and Poulin (2013) conducted their studies in rural settings, the remaining three obtained data from both rural and urban settings. In the context of development being historical, the articles do not explicitly describe how development is influences by the historical era in which one grew but all are recent articles written within the past six …show more content…
As presented by Baltes set of principles, the development is lifelong and spans across every stage of a person’s life including prenatal development, infancy, childhood, adolescence, adulthood and aging. According to the set of principles, development is lifelong, multidimensional, multidirectional, gains and losses, contextual and historical, and/or multidisciplinary. While age is the most examined variable in developmental psychology and affirm Baltes opinion that development is lifelong the other attributes he provided facilitates the understanding of human development. Psychology professionals examine chronological age in developmental psychology due to the fact that the performance of tasks is associated with age. For example, older children will perform at higher levels compared to their younger counterparts. The key aspects that developmental psychology focuses on include personality, motor skills, identity formation, cognitive development, emotional development, moral understanding, social change, language acquisition and self-concept. Hence, this paper has shown that human development begins from conception and is influenced by biological, social and environmental factors. For example, through the attachment theory, the emotional and behavioral development of children can be defined from childhood through adolescence to adulthood. Further, the setting in which
