Thematic Integration Impairments in Primary Progressive Aphasia: Evidence From Eye-Tracking.

abstract：:In addition to vision, audition plays an important role in sound localization in our world. One way we estimate the motion of an auditory object moving towards or away from us is from changes in volume intensity. However, the human auditory system has unequally distributed spatial resolution, including difficulty dist...
