The transition from childhood to adolescence is characterized by both structural and functional brain changes. Recent research describes highly dynamic and plastic cerebral and cognitive systems during aging. Moreover, the authors suggest that the refinement of the connections of this commissure that occur after age 6 optimize neural communication between the two cerebral hemispheres.
Developmental psychologists usually consider early adulthood to cover approximately age 20 to age 40 and middle adulthood approximately 40 to Choices concerning marriage and family are often made during this period.
However, toyear-old subjects name fewer items spontaneously and require more functional cues to arrive at the correct answer than do adults aged 18 to 29 years, suggesting not only that the vocabulary required to successfully complete the naming test has been acquired by age 16 to 17 but also that maturation of strategic retrieval functions may still be lacking.
According to the website of speech pathologist Caroline Bowen, at www. It means emotional investment in an object, activity or idea. It is marked by numerous physical changes as well as certain cognitive developments.
The few studies that have analyzed the association between these anatomical changes and cognitive performance during adolescence have found better performance associated with white matter diffusion properties [ 5354 ].
They recruited 18 healthy, right-handed participants 14 men, 4 women for their study.
It should be pointed out that decreased asymmetry is observed not only in the neocortex but also in other brain areas, including the hippocampus. According to KidsHealth at www. Erik Erikson refers to the problem posed at this stage as generativity vs.
Average Boston naming scores by age groups adapted from Zec et al. These researchers have found that negativity caused by stress or conditions such as depression or anxiety can even eventually lead to chronic physical conditions in otherwise healthy bodies.
A comprehensive picture of age-related changes in the volume of gray and white matter is provided by structural magnetic resonance imaging MRI studies, while functional MRI fMRI and magnetoelectroencephalographic MEG methods have generated information on neural activity associated with cognitive functions.
Add healthy eating and the elimination of tobacco and alcohol use to middle-age lifestyles, and major illnesses can literally be halted altogether. Most of the regions that showed significant developmental increases were in the left lateral and medial dorsal frontal cortex and the left parietal cortex, including the supramarginal gyrus.
The influence of such additional variables as gender, level of education, and language experience on language development is highlighted at the end of the paper. And by adequately managing major life stressors, many individuals gain a sense of empowerment and confidence.
This observation suggests that the degree of language lateralization decreases after a certain age, while cognitive processes become more symmetrically represented over time [ 77 ]. As people age, they must adjust to the increasing disability of their own bodies. It has been shown, for example, that infants who grow up in bilingual environments may have different windows for perceptual narrowing by retaining greater sensitivity to nonnative contrasts that reached a less narrow end state than monolingual infants [ ].
In the modern cultures of many nations, the careers of both spouses or partners frequently must be considered in making job choices. You receive more money, have more vacation time and other fringe benefits because you have earned it.
Conclusions This review has attempted to elucidate the typical development of language in relation to typical brain development and to reach some conclusions drawn by integrating research from the fields of neuropsychology and neuroimaging. Supposedly this is a time of great emotional upheaval, anxiety, and drastic changes in behavior.
Schooling appears to influence functional brain organization [ ] for a review see Ardila et al. Moreover, gender effects have been described in the reduction of gray matter and the increase in the volume of white matter that occurs in brain development during childhood and adolescence [ 51, ].
Cabeza and colleagues [ 79 ] have suggested that during cognitive task performance a reorganization of brain activation patterns occurs that is age related. However, there is an evident need to continue advancing in this direction.
Patterns of Brain Maturation Verbal generation measured by VF tests and vocabulary size measured by naming tests are obviously correlated with some of the neuroanatomical and neurophysiological changes that occur in the brain during childhood and adolescence.
Particularly influential in this regard are two tests: The language used by people from low socioeconomic sectors has also been reported as less fluent, characterized by a simpler grammatical structure, and much more reliant on emotional than logical strategies [ ].
They found that the increase of WM is much more prominent than the decrease in GM, results which revealed that the most significant changes were in the body of the corpus callosum related to the integration of sensory and motor cortical information and the right superior region of the corona radiata fibers projecting to and from the entire cerebral cortex, particularly the motor cortices.
Such findings have been observed in both cross-sectional and longitudinal studies. Such disorders may impact expressive or receptive skills. Although some of the studies described in this review were longitudinal, most were of the cross-sectional type which limits the possibilities of generalizing their results.
Use of blood oxygenation level-dependent BOLD signal with fMRI may produce acceptable spatial resolution, and the magnetic fields changes utilized in MEG allow tracking of the neural activity with reasonable time resolution.
Note that this review focuses on the development of oral language and does not include written language. Clearly, language development at these ages is linked to the development of other, nonlinguistic abilities, such as attention, social skills, memory, and many other individual characteristics [ 26 ].
What many consider a "crisis" might stem from a personality trait that makes coping with life's stresses difficult. Though a certain degree of functional lateralization has been observed in the human brain from birth, the assumption that lateralization increases with age means that the lateralization index can be used as a measure of brain maturation e.

This period lasts from 20 to 40 years depending on how these stages, ages, and tasks are culturally defined. A review of research demonstrates that both oral and written language continue to develop through adulthood.

Physical Development in Middle Adulthood As the human body ages and reaches a point where it is no longer growing and changing due to hormones, it slowly starts to change in other ways.
Age starts to take its toll much earlier on the body than most people think. A review of research demonstrates that both oral and written language continue to develop through adulthood. Studies show that such skills as the abilities to interpret metacognitive verbs, to make word associations, and to understand syntax improve with age.Language development in middle adulthood
