A probe signal paradigm measured attention to two properties – resonant frequency and number of colliding objects. Listeners completed a baseline task measuring absolute sensitivity at each stimulus against a background noise. Subsequently, stimuli served as both cues and targets; cue validity was probabilistic. When cue and target w
