Language production and visuospatial attention lateralize to different hemispheres. (A) Participants with typical language lateralization (blue, word generation against repetition; green, Landmark task against control task) are shown. (B) Same information is shown for the participants with atypical language lateralization. (C) Correlation of the lateralization patterns for all participants is displayed. In all but one participant, language production and spatial attention lateralized to opposite hemispheres regardless of whether the lateralization pattern was typical. Black diamonds show the outcome of the comparison between the Landmark (LM) and LM control (LMC) tasks. The gray triangles show the outcome of the analysis when the laterality index of the Landmark task is based on a comparison between the Landmark task and “rest” conditions, which gives less clear data.
