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 ...
Brain areas that undergo significant post-natal development, such as those involved in memory and emotion are more vulnerable to effects of early life stress. [ 58 ] [ 64 ] For example, the hippocampus continues to develop after birth and is a structure that is affected by childhood maltreatment. [ 64 ]
The Centers for Disease Control (CDC) divides Middle Childhood into two stages, 6–8 years and 9–11 years, and gives "developmental milestones for each stage". [119] [120] Middle Childhood (6–8). Entering elementary school, children in this age group begin to thinks about the future and their "place in the world".
Cognitive development is a field of study in neuroscience and psychology focusing on a child's development in terms of information processing, conceptual resources, perceptual skill, language learning, and other aspects of the developed adult brain and cognitive psychology.
Synaptic pruning, a phase in the development of the nervous system, is the process of synapse elimination that occurs between early childhood and the onset of puberty in many mammals, including humans. [1] Pruning starts near the time of birth and continues into the late-20s. [2]
Childhood is the age span ranging from birth to adolescence. [7] In developmental psychology, childhood is divided up into the developmental stages of toddlerhood (learning to walk), early childhood (play age), middle childhood (school age), and adolescence (puberty through post-puberty). Various childhood factors could affect a person's ...
