A theory of visual control of braking based on information about time-to-collision.

abstract：:Deaf individuals rely on facial expressions for emotional, social, and linguistic cues. In order to test the hypothesis that specialized experience with faces can alter typically observed gaze patterns, twelve hearing adults and twelve deaf, early-users of American Sign Language judged the emotion and identity of expr...
