Abstract

To examine the combined effects of ageing and bilingualism in language processing, we tested young and older mono- and bilingual speakers in L1 comprehension and production. In Experiment 1, bilinguals were slower to detect words than monolinguals in sentences with a low-constraint context, but not when a high-constraint context was provided. Older adults tended to outperform younger adults in high-constraint sentences. In Experiment 2, older speakers were slower than younger speakers to produce small-scope prepositional phrases (e.g., ‘the cone above the grape), suggesting more extensive planning. Bilingual disadvantages were observed in larger-scope complex phrases (e.g., ‘the cone and the pink grape’). Individual differences in language proficiency did not modulate the effects. The results support bilingual disadvantages in syntactic processing and age-preserved syntax, alongside semantic processing unaffected by either bilingualism or age. We found no interactions between age and bilingualism, suggesting that these two factors independently impact language processing.
双语和老龄化对语言加工的独立影响:来自理解和制作的证据
为了研究老龄化和双语对语言处理的综合影响,我们对年轻和年长的单语和双语使用者进行了L1理解和生产测试。在实验 1 中,在低限制语境的句子中,双语者比单语者察觉单词的速度慢,但在提供高限制语境时则不然。在高限制句子中,老年人的表现往往优于年轻人。在实验 2 中,年长者比年幼者在使用小范围介词短语(如 "葡萄上面的圆锥体")时速度更慢,这表明他们需要进行更广泛的计划。在使用范围较大的复杂短语(如 "圆锥体和粉红色葡萄")时,则出现了二语劣势。语言能力的个体差异并不影响这些效果。研究结果表明,在句法处理和年龄保留句法方面存在双语劣势,而语义处理则不受双语或年龄的影响。我们没有发现年龄和双语之间的交互作用,这表明这两个因素对语言处理的影响是独立的。
