Some child development studies that examine the effects of experience or heredity by comparing characteristics of different groups of children cannot use a randomized design; while other studies use randomized designs to compare outcomes for groups of children who receive different interventions or educational treatments.

The Bayley Scales of Infant and Toddler Development (version 4 was released September 2019) is a standard series of measurements originally developed by psychologist Nancy Bayley used primarily to assess the development of infants and toddlers, ages 1–42 months. [1]
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 ...
From position and maternal effects on gene expression to epigenetic inheritance [6] to the active construction and intergenerational transmission of enduring niches, [3] development systems theory argues that not only inheritance but evolution as a whole can be understood only by taking into account a far wider range of ‘reproducers’ or ...
Louise Bates Ames (October 29, 1908 – October 31, 1996) was an American psychologist specializing in child development. [1] Ames was known as a pioneer of child development studies, introducing the theory of child development stages to popular discourse.
Malnutrition in children is a huge problem in developing countries. Rising global temperatures can alter growing seasons for certain food groups, making it hard for children to get the proper nutrients they need for ideal human development. [21] Ecological, evolutionary, developmental biology compares these subgenres of biology.
Human embryology is the study of this development during the first eight weeks after fertilization. The normal period of gestation (pregnancy) is about nine months or 36 weeks. The germinal stage refers to the time from fertilization through the development of the early embryo until implantation is completed in the uterus.
Developmental plasticity is a general term referring to changes in neural connections during development as a result of environmental interactions as well as neural changes induced by learning. [1] Much like neuroplasticity , or brain plasticity, developmental plasticity is specific to the change in neurons and synaptic connections as a ...
