a, Results from experiment 1. Black lines connect the data of a particular subject. b, A different rate of the looming sound impairs the multimodal attentional gain (experiment 2). c, Tone pips with the same rate as the looming visual pattern enhance multimodal attentional control over the looming pattern, indicating that rate (or rhythm) is important (experiment 3). d, Paying attention to the congruent looming sound is required to enhance holding the visual looming pattern (experiment 4). e, The benefit of congruent sound also holds for the radial pattern and is not specific to the looming pattern (experiment 5). The dashed lines between the panels connect data of identical subjects. Filled circles indicate significance (t test, see Results); error bars denote ±1 SE.
