Document Summary

Cross-modal attention- the coordination of attention across 2 or more modalities. If participants had to pay attention to visual stimuli on the left side, then they would also notice the auditory stimuli on that same side; not the other visual stimulus. Ventriloquism effect is the mistaken perception that sounds are coming from their apparent but not equal source. Participants press one key to respond to a visual stimulus and another for auditory stimuli. They sometimes only press the visual stimulus key when visual and auditory stimuli presented together. System is biased to respond to the inputs that give more information (usually vision) Conflicting information is presented in several modalities one with best acuity dominates. Sound is better for relations in time. Visual stimuli are located closer in time to the sound stimuli. Early warning systems: exogenous spatial attention- attention to a given spatial location determined by.
