Short essay on adolescent puberty and sexuality Ruchismita Advertisements: Between the ages of 10 and 14 most boys and girls begin to notice changes taking place in their bodies. These changes, which occur over a number of years, are generally referred to as puberty. The changes take place in all boys and girls but they will start at different times and take place at different rates.
Sinauer Associates ; Search term The Development of Language: A Critical Period in Humans Many animals communicate by means of sound, and some humans and songbirds are examples learn these vocalizations.
There are, in fact, provocative similarities in the development of human language and birdsong Box B. Most animal vocalizations, like alarm calls in mammals and birds, are innate, and require no experience to be correctly produced.
For example, quails raised in isolation or deafened at birth so that they never hear conspecifics nonetheless produce the full repertoire of species -specific vocalizations. In contrasthumans obviously require extensive postnatal experience to produce and decode speech sounds that are the basis of language.
Importantly, Puberty speech linguistic experience, to be effective, must occur in early life. The requirement for hearing and practicing during a critical period is apparent in studies of language acquisition in congenitally deaf children.
Whereas Puberty speech babies begin producing speechlike sounds at about 7 months babblingcongenitally deaf infants show obvious deficits in their early vocalizations, and such Puberty speech fail to develop language if not provided with an alternative form of symbolic expression such as sign language; see Chapter This suggests that, regardless of the modalityearly experience shapes language behavior Figure Children who have acquired speech but subsequently lose their hearing before puberty also suffer a substantial decline in spoken language, presumably because they are unable to hear themselves talk and thus lose the opportunity to refine their speech by auditory feedback.
Babbling was judged by scoring hand positions and shapes that showed some resemblance to the components of American Sign Language. Examples of pathological situations in which normal children were never exposed to a significant amount of language make much the same point.
In one well-documented case, a girl was raised by deranged parents until the age of 13 under conditions of almost total language deprivation. Despite intense subsequent training, she never learned more than a rudimentary level of communication.
In contrast to the devastating effects of deprivation on children, adults retain their ability to speak and comprehend language even if decades pass without exposure or speaking.

In short, the normal acquisition of human speech is subject to a critical period: The process is sensitive to experience or deprivation during a restricted period of life before puberty and is refractory to similar experience or deprivations in adulthood.
On a more subtle level, the phonetic structure of the language an individual hears during early life shapes both the perception and production of speech.
Very young human infants can perceive and discriminate between differences in all human speech sounds, and are not innately biased towards the phonemes characteristic of any particular language. However, this universal appreciation does not persist.
Nonetheless, 4-month-old Japanese infants can make this discrimination as reliably as 4-month-olds raised in English-speaking households as indicated by increased suckling frequency or head turning in the presence of a novel stimulus.
By 6 months of age, however, infants show preferences for phonemes in their native language over those in foreign languages, and by the end of their first year no longer respond to phonetic elements peculiar to non-native languages.
The ability to perceive these phonemic contrasts evidently persists for several more years, as evidenced by the fact that children can learn to speak a second language without accent and with fluent grammar until about age 7 or 8.
After this age, however, performance gradually declines no matter what the extent of practice or exposure Figure The ability to score well on tests of English grammar and vocabulary more A number of changes in the developing brain could explain these observations.
One possibility is that experience acts selectively to preserve the circuits in the brain that perceive phonemes and phonetic distinctions. The absence of exposure to non-native phonemes would then result in a gradual atrophy of the connections representing those sounds, accompanied by a declining ability to distinguish between them.
In this formulation, circuits that are used are retained, whereas those that are unused get weaker and eventually disappear. Alternatively, experience could promote the growth of rudimentary circuitry pertinent to the experienced sounds.
The reality, however, is considerably more complex than either of these scenarios suggest. Experiments by Patricia Kuhl and her colleagues have demonstrated that as a second language is acquired, the brain gradually groups sounds according to their similarity with phonemes in the native language.Puberty is the time of change when young people begin to develop the outward signs of becoming an adult and when they become able to reproduce (have a baby).
Puberty starts when hormones from part of the brain (pituitary gland) act on the ovaries or testes to begin sexual changes in both boys and girls. Breast development during puberty. The beginning of breast development is one of the earliest signs of puberty in girls, the appearance of pubic hair being the other.
In other words, pubic hair and breast buds appear close together. Breast development normally begins about 1 year before the menstrual period begins.
The development takes several years. List of causes of Delayed puberty and Dementia and Speech symptoms, alternative diagnoses, rare causes, misdiagnoses, patient stories, and much more. Normal puberty begins between eight and 14 years of age in girls and between nine and 14 years of age in boys.
