What Can L2ers Tell Us about Codeswitching? Mood Selection in Spanish

Abstract

An increasing amount of research shows that bilinguals that engage in codeswitching (CS) may show different patterns of usage and sensitivity to particular linguistic structures depending on community norms. Additionally, proficiency may play a different role in sensitivity to code-switched utterances depending on speaker background, as well as the structure investigated. In this study, we aim to examine how bilinguals not exposed to CS in the community rate CS vs. unilingual sentences involving mood selection in Spanish. In an online acceptability judgment task (AJT), 20 Spanish L2ers rated sentences containing verbs in the indicative and subjunctive mood in restrictive relative clauses manipulated for the specificity of the antecedent in two separate sessions: a Spanish monolingual mode and a CS session. The L2ers did not show evidence of a CS effect and maintained a mood distinction according to the specificity of the antecedent both in unilingual and codeswitched sentences. These results are in contrast with the results previously reported for Spanish heritage speakers (HSs), where a CS effect is attested in the loss of preference for the subjunctive in nonspecific relative clauses in the CS vs. the monolingual Spanish condition. Additionally, this distinction is found at both lower and higher proficiency levels. The differences between these speakers and HSs are consistent with data from previous research on CS effects on phonology and Det–N switches. We argue that exposure to community norms is necessary for the acquisition of patterns not related exclusively to the grammaticality of switch junctures (I-language).
