Synaptogenesis is particularly important during an individual's critical period, during which there is a certain degree of synaptic pruning due to competition for neural growth factors by neurons and synapses. Processes that are not used, or inhibited during their critical period will fail to develop normally later on in life.
The development of the nervous system in humans, or neural development, or neurodevelopment involves the studies of embryology, developmental biology, and neuroscience.These describe the cellular and molecular mechanisms by which the complex nervous system forms in humans, develops during prenatal development, and continues to develop postnatally.
This is over a short life-span (female about one year) where wild common octopuses focus most of their energy on mating and offspring care. [ 36 ] [ 37 ] Findings suggest that the octopus vulgaris like other short-lived species have a complex hippocampal proliferation, [ 38 ] [ 39 ] needed for spatial/navigation, and short and long-term memory.
Levinson's work includes research on differences in the lives of men and women. He published The Seasons of a Man's Life and The Seasons of a Woman's Life, with findings that men and women went through essentially the same crises but differed in "The Dream." The author wrote that men's dreams are centered around occupations and women's are ...

Health psychology is a discipline that understands the psychological, behavioral, and cultural aspects that affect the physical health and ...
Researchers distinguish between mean level and rank order changes in trait standing during old age. [20] Their study of personality trajectories is thus contingent on time and on age considerations. Mottus, Johnson and Geary (2012) found that instability engendered by aging does not necessarily affect one's standing within an age cohort.
The dual systems model, also known as the maturational imbalance model, [1] is a theory arising from developmental cognitive neuroscience which posits that increased risk-taking during adolescence is a result of a combination of heightened reward sensitivity and immature impulse control.
However, the relationship between psychological maturity and age is a difficult one, and there has been much debate over methods of determining maturity, [40] considering its subjective nature, relativity to the current environment and/or other factors, and especially regarding social issues such as religion, politics, culture, laws, etc. [41]
