Imageability Effects on Sentence Judgment by Right Brain-Damaged Adults. In Clinical Aphasiology Conference: Clinical Aphasiology Conference (2008 : 38th : Jackson Hole, WY : May 27 - June 1, 2008) / : (2008).
The effect of right hemisphere damage on imagery generation was tested using a previously validated sentence verification task. While subjects with right hemisphere-damaged (RHD) took longer than controls to reject false sentences regardless of whether this judgment required imagery generation, their response time deficit on High-imagery items was less than that on Low imagery items, suggesting that they have a deficit in recognizing non-imageable knowledge and/or a heightened tendency to engage in imagery generation in response to verbal stimuli. A post hoc analysis also suggested that the group with RHD was selectively impaired in motor, rather than visual, imagery generation.
