The slowing brings about matched behaviour (slowed response). The cognitive process is critical in communication and is the major determining factor of complete communication process. There are distinct differences in the way young people talk and pass information compared to the old and this is determined by the way of socialization and interactions. Young people adopt communication means that are very convenient with their interaction level and the social changes around them like communication and so on while older people tend to like more official form of language communication. Young people communicate informally with the use of corrupted language version like slung, unfamiliar acronyms and jargon words.
Social interaction is the major element that brings about the machinery to spread the use of sound and change in language outward and upward through the social ladder. For better understanding of the linguistic features, a phonological variation in the current society has to be done (Milroy et al 2003). Over the past 15- 20 years, data has revealed that there is a wider range of factors that determine the phonological changes in the society. The interpretation of these variations has led linguists to shift from the normal demographic correlations focused on investigation technique to participant observation in smaller factions and networks to reveal the social incentive for the type of linguistic emulation that lead to the spread of variation through populations, Chambers (2002).
Normally observed population and other demographic patterns, the phonological variation shows that there is a spread between and via the society structure and communication networks. Phonological changes can begin anywhere; however those that spread far and wide usually originate from the urban areas and are common among the young than the older people. Recent research in linguistic studies indicates that sound change just like other innovations spreads through a network of influence and progressively, Edwards (1993).
The Social Structure
The social structure is the major contributor to the changes and spread of language variations. Social studies reveal that the normal socio-economic stratification of the phonological variables in the society changes as people rise from working class through the social hierarchy, Chambers (1995). The extent of phonological variation is further indicated in the age difference within the society (young and old) have a considerable increase of innovative types down the age continuum. In the age bracket, there is some discontinuation as the middle aged speakers show greater stylish range than the old and young people and so doing, they reveal a conservative speech in official manner compared to the old and young, they at times even show more innovative speeches in casual manner than the young people(Milroy et al 2003). Age discontinuity is difficult to reveal between the adolescents and pre-adolescents.
Data from previous research studies; moth age graded information particularly about the demographic groups under the age of 21 are grouped together making it almost impossible to evaluate the differences among the finer groups of pre-adults, Edwards (1993). The collective data indicate a gradual
