ABSTRACT
Not long after Lenneberg first introduced his Critical Period Hypothesis (CPH) and its concomitant theory of lateralization in 1967, it was extrapolated to second language acquisition (SLA) and accepted by many linguists, including Oyama (1976), Lamendella (1977), and Scovel (1981) as the most probable explanation for accented speech in adult SLA. "The extent of the foreign accent is directly correlated with the age at which the second language is acquired" (Lenneberg, 1967, p. 9).
