A fetus is a stage in the human development considered to begin nine weeks after fertilization. [4] [5] In biological terms, however, prenatal development is a continuum, with many defining features distinguishing an embryo from a fetus. A fetus is also characterized by the presence of all the major body organs, though they will not yet be ...
Physical development. Typically grows between 1 and 1.5 inches (2.5 and 3.8 cm) and gains about 2 pounds (910 g). [20] Motor development. Hands kept in tight fists. [21] Equal movement of arms and legs on both sides. [21] Able to briefly hold up head when in prone position. [21] Arm thrusts are jerky. [22] Brings hands close to eyes and mouth. [22]
Development may also occur as a result of human nature and of human ability to learn from the environment. There are various definitions of the periods in a child's development, since each period is a continuum with individual differences regarding starting and ending.
Any aspect of human development is best described and explained in relation to the whole person and their social context, as well as to their biological and cognitive-affective parts. This can be called a holistic or contextualist viewpoint, and can be contrasted with the reductionist approach to development, which tends to focus solely on ...
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.
Erikson's stages of psychosocial development, as articulated in the second half of the 20th century by Erik Erikson in collaboration with Joan Erikson, [1] is a comprehensive psychoanalytic theory that identifies a series of eight stages that a healthy developing individual should pass through from infancy to late adulthood.
The development of the human mind is complex and a debated subject, and may take place in a continuous or discontinuous fashion. [4] Continuous development, like the height of a child, is measurable and quantitative, while discontinuous development is qualitative, like hair or skin color, where those traits fall only under a few specific phenotypes.

Cortical white matter increases from childhood (~9 years) to adolescence (~14 years), most notably in the frontal and parietal cortices. [8] Cortical grey matter development peaks at ~12 years of age in the frontal and parietal cortices, and 14–16 years in the temporal lobes (with the superior temporal cortex being last to mature), peaking at about roughly the same age in both sexes ...
