Event-related fMRI (n=30) was used to measure the cortical effects of the differences in acceptability between ungrammatical sentences and three types of wh-movement in Danish: short movement (to the front of an embedded clause), long movement (to the beginning of the matrix clause), and movement across another wh-phrase. The neural activation in LIFG was predicted to correlate negatively with the level of acceptability.

N2 - The aim of this study was to investigate whether LIFG activation was sensitive to increases in syntactic working memory load triggered by multiple extractions from an embedded clause, so-called island violations, and whether there was any difference between argument and adjunct extraction. Event-related fMRI (n=30) was used to measure the cortical effects of the differences in acceptability between ungrammatical sentences and three types of wh-movement in Danish: short movement (to the front of an embedded clause), long movement (to the beginning of the matrix clause), and movement across another wh-phrase. The neural activation in LIFG was predicted to correlate negatively with the level of acceptability. Ungrammatical sentences were predicted to engage LIFG, potentially overlapping with the effects of acceptability.
