Age-graded variation
In linguistics, age-graded variation is differences in speech habits within a community that are associated with age. Age-grading occurs when individuals change their linguistic behavior throughout their lifetimes, but the community as a whole does not change.
Definition
The term âage-gradingâ was first introduced by anthropologist/linguist Charles F. Hockett, but has been defined as it is used today by sociolinguist William Labov, who identified it as an individual linguistic change against a backdrop of community stability. Age-grading is not limited to changes at any one particular stage in life, but can be studied in the way that babies, adolescents, young adults speak, and the elderly speak.Age-grading involves the use of stable sociolinguistic variables, or features that are not currently undergoing any linguistic change. Linguistic features that are age-graded typically are stigmatized or have a high degree of social awareness and can be consciously controlled. For this reason, age-graded variables tend to be semantic as opposed to phonetic. Age-graded changes recur at a particular age in successive generations and are regular and predictable changes. These changes are thought to mark developmental/maturational stages in the individualâs life.
The classic age-grading pattern
The expected pattern is a u- or v-shaped curve. Nonprestigious age-graded linguistic features tend to peak during adolescence âwhen peer group pressure not to conform to societyâs norms is greatestâ. The use of standard or prestige forms peaks between the ages of 30 and 55. When people reach middle age, they tend to follow societal norms more because that is when the societal pressure to conform is greatest. At this stage of life, people become more conservative and use the fewest vernacular forms. Nonprestigious forms may resurface in old age when people are out of the workforce and social pressures are reduced.Age-grading and the apparent-time hypothesis
Age-graded variation stands in contrast to the apparent-time hypothesis, which assumes that an individualâs vernacular does not change once they are past adolescence. According to the apparent-time hypothesis, age-stratified variation is often indicative of a linguistic change in progress. For example, if in a survey of a population, patterned differences between the speech of individuals 75 years old, 50 years old, and 25 years old may indicate changes that have occurred over the past 50 years. This presents a problem when studying age-graded variation because age-grading relies on individuals changing their speech patterns throughout their lives. The applicability of age-graded variation should be confirmed by real-time evidence. This can come from a longitudinal study, which tracks the same people.Age-grading in different age groups
Children/adolescents
When children first learn their language, they learn language in the way of their mother and/or primary caretakers. Vernacular reorganization occurs when children adopt a norm that is different from the one they have acquired. This happens in the preadolescent and adolescent years and is necessary for linguistic change to advance.It is not uncommon for adolescents to have certain linguistic variation in their speech. Adolescence is a transitional period when children become adults and move away from their family identity to express themselves as individuals. During this period, age-segregated networks form, giving rise to age-graded variation. Adolescents tend to lead with an increased use of vernacular and linguistic variables to differentiate themselves from the adult population.
When studies began to include younger age groups, researchers discovered that the frequency of incoming linguistic changes is highest among 15- to 17-year-olds, but lower among 11- to 14-year-olds and people in their twenties. This is called the adolescent peak.
