同化假说认为，第二语言学习会招募大脑网络来处理母语，而适应假说则认为，学习第二语言会招募不参与母语处理的大脑结构。本研究通过检测一组以汉语为母语的人的大脑激活来验证这些假说，这些人是英语熟练程度不同的晚期双语者，他们在fMRI中对视觉呈现的英语单词对进行押韵判断(CE组)。同化通过比较CE组和以汉语为母语的人用汉语完成押韵任务(CC组)，并通过比较CE组和以英语为母语的人用英语完成押韵任务(EE组)来检查适应性。CE组的激活与CC组非常相似，支持同化假说。对同化假说的另一个支持是，CE组的熟练程度越高，汉语网络(如CC>；EE定义的)的激活增加，而英语网络(如EE>；CC定义的)的激活减少，包括左额中回、右侧顶下小叶和右侧楔前回。虽然大多数结果支持同化，但也有一些证据表明，CE组在包括右侧枕中回在内的汉语网络中激活较少，该回被认为参与了汉字的整体视觉空间加工。
The assimilation hypothesis argues that second language learning recruits the brain network for processing the native language, whereas the accommodation hypothesis argues that learning a second language recruits brain structures not involved in native language processing. This study tested these hypotheses by examining brain activation of a group of native Chinese speakers, who were late bilinguals with varying levels of proficiency in English, when they performed a rhyming judgment to visually presented English word pairs (CE group) during fMRI. Assimilation was examined by comparing the CE group to native Chinese speakers performing the rhyming task in Chinese (CC group), and accommodation was examined by comparing the CE group to native English speakers performing the rhyming task in English (EE group). The CE group was very similar in activation to the CC group, supporting the assimilation hypothesis. Additional support for the assimilation hypothesis was the finding that higher proficiency in the CE group was related to increased activation in the Chinese network (as defined by the CC > EE), including the left middle frontal gyrus, the right inferior parietal lobule, and the right precuneus, and decreased activation in the English network (as defined by the EE > CC), including the left inferior frontal gyrus and the left inferior temporal gyrus. Although most of the results support assimilation, there was some evidence for accommodation as the CE group showed less activation in the Chinese network including the right middle occipital gyrus, which has been argued to be involved in holistic visuospatial processing of Chinese characters.
