As genetic factors and events during prenatal life may strongly influence developmental changes, genetics and prenatal development usually form a part of the study of child development. Related terms include developmental psychology , referring to development from birth to death, and pediatrics , the branch of medicine relating to the care of ...
Early childhood development is the period of rapid physical, psychological and social growth and change that begins before birth and extends into early childhood. [1] While early childhood is not well defined, one source asserts that the early years begin in utero and last until 3 years of age.
Development before birth, or prenatal development (from Latin natalis 'relating to birth') is the process in which a zygote, and later an embryo, and then a fetus develops during gestation. Prenatal development starts with fertilization and the formation of the zygote , the first stage in embryonic development which continues in fetal ...
The NCS was designed to examine the effects of the environment—broadly defined to include factors such as air, water, diet, sound, family dynamics, community, and cultural influences— and genetics on the growth, development, and health of children across the United States. The NCS was designed to follow approximately 100,000 children, some ...
Personality development is also dimensional in description and subjective in nature. [2] That is, personality development can be seen as a continuum varying in degrees of intensity and change. It is subjective in nature because its conceptualization is rooted in social norms of expected behavior, self-expression, and personal growth.
Many theories of development have aspects of identity formation included in them. Two theories directly address the process of identity formation: Erik Erikson's stages of psychosocial development (specifically the Identity versus Role Confusion stage), James Marcia's identity status theory, and Jeffrey Arnett's theories of identity formation in emerging adulthood.
Each child develops in a unique way; however, using norms helps in understanding these general patterns of development while recognizing the wide variation between individuals. One way to identify pervasive developmental disorders is if infants fail to meet the development milestones in time or at all.
The methods used to analyze behavior in child development are based on several types of measurements. Single-subject research with a longitudinal study follow-up is a commonly-used approach. Current research is focused on integrating single-subject designs through meta-analysis to determine the effect sizes of behavioral factors in development ...
