猫和人类的声音定位依赖于以头部为中心的声音线索。研究表明,人类能够在快速的头部运动中定位指向目标或其他感兴趣的物体的声音。我们研究了猫是否能够利用类似的动态声学线索来定位在快速的眼球注视转移过程中传递的声学目标。我们用视觉-听觉两步任务训练猫,在跳跃性眼-头注视转向先前的视觉目标时,我们提供短暂的声音爆发。在水平或垂直方向上,动态任务(两步扫视)与可比静态任务(头部稳定时的单步扫视)在准确度或精密度上没有一致或显著差异。猫似乎能够处理动态的听觉线索,并执行复杂的运动调整,以准确地定位在快速的眼睛-头部凝视转换的听觉目标。
Sound localization in cats and humans relies on head-centered acoustic cues. Studies have shown that humans are able to localize sounds during rapid head movements that are directed toward the target or other objects of interest. We studied whether cats are able to utilize similar dynamic acoustic cues to localize acoustic targets delivered during rapid eye-head gaze shifts. We trained cats with visual-auditory two-step tasks in which we presented a brief sound burst during saccadic eye-head gaze shifts toward a prior visual target. No consistent or significant differences in accuracy or precision were found between this dynamic task (2-step saccade) and the comparable static task (single saccade when the head is stable) in either horizontal or vertical direction. Cats appear to be able to process dynamic auditory cues and execute complex motor adjustments to accurately localize auditory targets during rapid eye-head gaze shifts.
