Aims: The study investigates the effects of L2 proficiency and L2 exposure on L2-to-L1 cross-language activation (CLA) in L1-dominant bilinguals. In so doing, it tests the predictions made by prominent models of the bilingual lexicon regarding how language experience modulates CLA. Design: The participants (27 L1-dominant L1 English–L2 Afrikaans speakers) completed a visual world eye-tracking task, conducted entirely in English, in which they saw four objects on a screen: a target object, which they were instructed to click on; a competitor object, whose Afrikaans label overlapped phonetically at onset with the English target object label; and two unrelated distractors. Language background data were collected using the Language History Questionnaire 3.0. Analysis: A growth curve analysis was performed to investigate the extent to which the background variables modulated looks to the Afrikaans competitor item versus to the two unrelated distractor items. Findings: Increased L2 exposure was associated with greater CLA, which is consistent with models suggesting that exposure modulates the likelihood and speed with which a linguistic item becomes activated. Moreover, CLA was reduced at higher levels of L2 proficiency, which aligns with accounts of the bilingual lexicon positing that parasitism of the L2 on the L1 is reduced at higher proficiency levels, leading to reduced CLA. Originality: L2 activation during L1 processing and the variables that modulate it are not well documented, particularly among L1 speakers with limited proficiency in and exposure to the L2. Significance: The findings contribute to the evaluation of competing accounts of bilingual lexical organization. [ABSTRACT FROM AUTHOR]

In the online processing of long-distance wh-dependencies, native speakers have been found to make use of intermediate syntactic gaps, which has the effect of facilitating dependency resolution. This strategy has also been observed in second language (L2) speakers living in an L2 immersion context, but not in classroom L2 learners. This research note investigates whether there is evidence of use of the intermediate gap among L2 speakers that have received considerable naturalistic exposure to the L2 from a young age, but do not live in a standard immersion context. Two groups of participants, one L1 English and one L1 Afrikaans–L2 English, completed a self-paced reading task involving English sentences containing long-distance wh-dependencies. The data were analysed using Bayesian regression. The results indicate that the intermediate gap facilitated dependency resolution in the L1 English group but not in the L2 group. Increased L2 exposure seemed to increase sensitivity to the intermediate gap among the L2 speakers, but was not associated with faster dependency resolution. The findings suggest that although non-immersive L2 experience affects L2 processing of abstract grammatical cues, it may be less effective than fully immersive experience in engendering nativelike processing of long-distance wh-dependencies.
