The role of stress on the language-independence and code-switching phenomena

this investigation studies the extent to which stress affects the assumed functional separation of coordinate bilingual's linguistic organization. Spanish/English bilinguals were subjects in a GSR linguistic conditioning experiment using two intensities of buzzer sounds (stressful conditions) and two lists of words. One word for each list functioned as the conditioned stimulus. Generalization to semantically, phonemically, and unrelated words occurred in both languages and buzzer conditions. We found a differential impact of the buzzer on the functional separation of the languages, although not in the direction predicted. We concluded that stress produced code-switching, and hence, a primitivization of the subject's cognitive and linguistic functioning is assumed to have occurred. These findings are important in understanding the way stress affects the bilingual's languages at the linguistic and cognitive levels. They are also important in understanding the role of stress in language development and in the transfer of linguistic information.Different portions of this paper were presented at several scientific meetings, including the conference on Treating Hispanic Clients: Cultural, Ethnic and Linguistic Considerations, Long Island University, May 1986, and the Annual Convention of the New York State Psychological Association, April 1987
