Examples of stimulus pairs from the ten experimental conditions. The participants' task was to judge whether a given stimulus pair was contextually congruent or incongruent (e.g., “boat” and “lake” are contextually congruent, whereas “tractor” and “hotel” are incongruent). The baseline conditions required participants to judge whether two random-letter strings (one uppercase and one lowercase) were the same or different.

Results for the parahippocampal ROI analyses. a, Sagittal MRI brain slices depicting results from the interaction analysis (green) and conjunction analysis (red); yellow arrows indicate activation maxima. The area outlined in white shows the PPA inferred from the contrast picture-scene > picture-object. b, Parameter estimates (±1 SE) from the interaction analysis shown separately for the eight contextual judgment task conditions (relative to baseline) and for left and right parahippocampal cortex. c, Parameter estimates (±1 SE) from the conjunction analysis shown separately for the eight contextual judgment task conditions (relative to baseline) for the left parahippocampal cortex.

Results from the whole-brain analyses. a, Sagittal MRI brain slices depicting results from the interaction analysis (green). b, Sagittal MRI brain slices depicting results from the conjunction analysis (red).
