The perception of heading during eye movements

Article Abstract:

People require more than just visual information to accurately determine their heading if they are also tracking a moving object while moving forward. Such information comes from the extraocular and neck muscles as the object is tracked by the eye and head, and is used to discount the visual effects of rotation. This information is not available if the rotation is merely simulated in the image presented to the eye, so the person is not able to make corrections and fails to indicate their heading accurately. These effects occur only if the object being tracked is moving fairly rapidly.

Perceptual bias for rising tones

Article Abstract:

The rising intensity of an approaching sound source can specify the arrival time of the source. Experiments have shown that listeners over-estimated the changes in level of rising level tones, relative to equivalent falling level tones. Results indicated an asymmetry in the neural coding of harmonic rising and falling intensities, and suggest that rising intensity harmonic sounds have perceptual priority.
