Cross-modality correspondence between pitch and spatial location modulates attentional orienting.

摘要: The brain constantly integrates incoming signals across the senses to form a cohesive view of world. Most studies on multisensory integration concern roles spatial and temporal parameters. However, recent findings suggest cross-modal correspondences (eg high-pitched sounds associated with bright, small objects located high up) also affect integration. Here, we focus association between auditory pitch location. Surprisingly little is known about cognitive perceptual roots this phenomenon, despite its long use in ergonomic design. In series experiments, explore how mapping affects allocation attention an attentional cuing paradigm. Our results demonstrate that low tones induce shifts upper or lower locations, depending height. Furthermore, pitch-induced effect susceptible contextual manipulations volitional control. These interaction location originates from level rather than response alone. flexible location, as well susceptibility top-down control, suggests primarily mediated by processes after initial sensory encoding occurs at relatively late stage voluntary orienting.
