Research has shown that L1 speakers can routinely generate mental imagery corresponding to sentence meaning in reading comprehension. This may reflect an efficient process of semantic integration in which information from the input combines with an individual's linguistic and real world knowledge to form a semantic representation of a sentence. Semantic integration in L2 reading has received limited attention. The present study attempted to examine the activation of mental imagery in reading among L2 speakers and thus to assess the efficiency of semantic integration during L2 reading. L2 Korean learners were tested on a sentence-based picture recognition task in which they were asked to respond to a picture immediately after reading a sentence related to the picture. Results showed that L2 Korean learners resembled native Korean speakers in their ability to generate mental imageries that reflected subtle semantic differences in sentence input.
