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

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).

The use of default forms in codeswitching

This paper examines the effects that codeswitching (CS) has on mood selection in restrictive relative clauses in the Spanish of heritage speakers (HSs). Spanish HS participants completed an online acceptability judgment task in which they rated monolingual (i.e., unilingual) and codeswitched sentences containing verbs in indicative and subjunctive mood in restrictive relative clauses manipulated for specificity of the antecedent. The results indicated an association of the subjunctive with non-specificity in monolingual sentences that was lost in the codeswitched sentences, although this effect was modulated by proficiency. These results are discussed in terms of the use of default forms in CS.

ON COMPLEXITY AND DIVERGENCE IN HERITAGE LANGUAGE GRAMMARS

For more than a decade, research on heritage speakers’ (HSs’) mood selection has documented a high degree of variability in their interpretation and use of mood morphology in variable contexts. Most of the previous literature, however, has focused on late-acquired alternations, and often limited analyses to one form (i.e., subjunctive), making it difficult to draw conclusions about HSs’ knowledge of mood distinctions. This study intends to fill this gap by examining Spanish HSs’ (n = 76) and Spanish-dominant controls’ (n = 25) interpretation and use of an early acquired mood alternation, where the presence of indicative or subjunctive conveys the report of an assertion or a command. Results from two experimental tasks reveal that, even though HSs’ performance tends to differ from that of controls’—especially at lower levels of proficiency—the nature and extent of their divergences suggests the need to embrace a more nuanced analysis of HSs’ linguistic outcomes when examining modal contrasts.

Re-examining the role of mood selection type in Spanish heritage speakers’ subjunctive production

Verbal morphology is a particularly vulnerable domain in the grammars of Spanish heritage speakers (HSs). Among the most frequently studied phenomena is mood selection, identified as a pervasive locus of variability that affects the production of subjunctive more prominently. The present article explores this area of research by examining the effects of mood selection type on HSs’ subjunctive use. In contrast with previous studies, this investigation controls for propositional modality, focusing its analyses on instances of obligatory and variable subjunctive selection within deontic predicates. Results from a production task revealed that, despite the presence of between-group differences driven by participants’ levels of proficiency, type of selection did not significantly modulate their rates of subjunctive use. These findings challenge previous claims about the extent to which this factor affects Spanish HSs’ performance, and highlight the importance of considering propositional modality when examining the acquisition of mood.
