A quantitative method is introduced for detecting and correcting artifactual signal changes in BOLD time series data arising from the magnetic field warping caused by motion of the articulatory apparatus when speaking aloud, with extensions to detection of subvocal articulatory activity during silent reading. Whole-head images allow the large,…

Meaningful visual experience requires computations that identify objects as the same persisting individuals over time, motion, occlusion, and featural change. This article explores these computations in the tunnel effect: When an object moves behind an occluder, and then an object later emerges following a consistent trajectory, observers…

Reviews two projects studying the nature of mental representations of space induced entirely by language. The first project investigates perspective in descriptions of large-scale (e.g., convention center, town) space. The second project investigates mental representations of objects located immediately around the body. (37 references) (KRN)
