The present investigation examined the functioning of inhibitory mechanisms in younger and older bilinguals using a bilingual version of the Stroop test. The study predicted different patterns of age related decline in inhibitory mechanisms (inter- and intralingual interference) in bilinguals depending on their level of proficiency. Consistent with expectations, older bilinguals were slower when they responded in their non-dominant language. Furthermore, older unbalanced bilinguals showed greater interlingual interference when they responded with their second language to visual stimuli written in their dominant language. Balanced bilinguals showed equivalent interference effects between all conditions. These findings suggest that manipulating two languages may enhance the efficiency of inhibitory mechanisms.
本研究使用双语版的斯特鲁普测试，考察了年轻和年长双语者抑制机制的功能。该研究预测，根据双语者的熟练程度，其抑制机制（语内和语间干扰）与年龄相关的衰退模式会有所不同。与预期一致，年长的双语者在用非优势语言做出反应时速度较慢。此外，年长的非平衡双语者在用第二语言对用其优势语言书写的视觉刺激做出反应时，表现出更大的语间干扰。平衡双语者在所有条件下表现出同等的干扰效应。这些发现表明，操控两种语言可能会提高抑制机制的效率。
