Changes in an Idiolect from Childhood to Middle Age
Abstract
Since the 1960s, sociolinguists have been investigating dialect change mainly by
using the so-called apparent time method, which compares the spoken language
of people from different age groups. In recent decades, researchers have begun
to test the apparent time method by combining it with the real time method, which
concentrates on the influence of time in the language of a certain speech community or certain individuals. When the samples under investigation are collected by using the same principles and represent the same community at different times, the study can be called a trend survey. A more laborious and rarer method is a longitudinal follow-up study of individual infonnants, a panel survey, which is usually realized as part of a more extensive trend survey.
