fMRI-related behavior in LG. (A, B) LG's average performance in the scanner in a 1-back same-different comparison task from the 3 category-selectivity scans (2 scans with line-drawing stimuli, 1 scan with grayscale pictures stimuli, see Methods for more details). Responses were collected via a response box. (A) percent correct, (B) reaction time. (C) LG's object naming performance (in percent correct, compared to 9 healthy controls) as measured immediately after the scan outside the scanner. The stimuli consisted of the stimuli from the completion experiment (Lerner et al. 2001), see Methods and Results for more details). Yellow bars indicate LG's performance, gray bars, controls. An illustration of the stimuli of the different conditions is given below the bars. Note that LG performed well above chance in the comparison task (A, B), while his performance was significantly impaired in the naming task (C). In the completion experiment (C), even though LG's performance was already below controls in the whole condition (controls: 100 ± 0%, LG: 62%), his performance dramatically dropped when parts of the image were occluded by bars (grid: controls: 90.8 ± 1.2%, LG: 17%; scrambeled: controls: 30.7 ± 12%, LG: 2%).
