Abstract
Linguistic studies focusing on monolinguals have often examined individuals with
considerable experience using another language. Results of a methodological review
suggest that conflating ostensibly ‘multicompetent’ individuals with monolinguals
is still common practice. A year-long longitudinal study of speech production
demonstrates why this practice is problematic. Adult native English speakers
recently arrived in Korea showed significant changes in their production of
English stops and vowels (in terms of voice onset time, fundamental frequency,
and formant frequencies) during Korean classes and continued to show altered English
production a year later, months after their last Korean class. Consistent with
an INCIDENTAL PROCESSING HYPOTHESIS (IPH) concerning the processing of
ambient linguistic input, some changes persisted even in speakers who reported
limited active use of Korean in their daily life. These patterns thus suggest that the
linguistic experience obtained in a foreign language environment induces and then
prolongs restructuring of the native language, making the multicompetent native speaker in a foreign language environment unrepresentative of a monolingual in
a native language environment. Such restructuring supports the view that one’s
native language continues to evolve in adulthood, highlighting the need for researchers
to be explicit about a population under study and to accordingly control
(and describe) language background in a study sample.
