Lifespan Development and Personality Paper
Introduction
According to Carpenter and Huffman (2010) Developmental psychology is the study of age-related changes in behavior and mental processes from conception to death. Week Four learning material (syllabus) explains that “developmental psychology seeks to address various aspects of human development, including physical, cognitive, social, moral, and personality development” (Krawczyn's, 2010).

(How Kids Develop, 2008). This factor of physical development would be hereditary influence. Some factors that influences child development is the environment, if the mother is a smoker or drinks alcohol she can physically affect the child that she is carrying, with certain birth defects, premature births, low birth weight, malformations, deformities, and abnormal brain cells causing the child to be slow, or retarded even cause death. Physically tobacco and alcohol affects the child’s behavioral abnormalities and cognitive problems.
