Developmental Psychology: Cognitive development · Development of the self · Emotional development · Language development · Moral development · Perceptual development · Personality development · Psychosocial development · Social development · Developmental measures


Human development is the process of growing to maturity and reaching one's full potential. In biological terms, this entails growth from a one-celled zygote to an adult human being. The psychological study of human development is called developmental psychology.

We can conceive of human development in a variety of ways. In political-economic terms, human development has to do with stability, security and relative prosperity. In social terms, it has to do with literacy, education, social relationships, quality of life, etc. In moral terms, it has to do with the development of the conscience, moral awareness, and the will and capacity to act according to our knowledge of what is right. In psychological terms, human development has to do with mental health, self-esteem, success in significant relationships, happiness

Biological developmentEdit

Sperm-egg

A spermatozoon fertilizing an ovum

Development begins with fertilization, the process by which the male gamete, the sperm cell, and the female gamete, the oocyte, fuse to give rise to a diploid cell, the zygote.

In medicine, pregnancy is defined as beginning when a fertilized zygote becomes implanted in a woman's uterus. This occurs when the zygote then becomes embedded into the endometrium (lining of the uterus) where it forms a placenta, for the purpose of receiving essential nutrients through the uterus wall. The umbilical cord in a newborn child signifies the remnants of implantation.

The zygote undergoes rapid mitotic divisions with no significant growth (a process known as cleavage) and cellular differentiation, leading to development of an embryo.

Childbirth is the process in which the baby is born. It is considered by many to be the beginning of a person's life, where age is defined relative to this event in most cultures.

Developmental stagesEdit

Terms for developmental age groups include, with their approximate age ranges:

Physical development milestones Edit

Main article: Milestones of infant and child development

Note: the Tanner stages can be used to approximately judge a child's age based on physical development.
