Orienting responses to rising- and falling-intensity white noise stimuli. (A) Time-amplitude waveforms and power spectrum of the white noise stimuli used in condition 2. (B) Duration of head-orienting responses to rising- and falling-intensity white noise. Black bars represent responses to rising-intensity sounds, whereas white bars represent falling-intensity sounds. The y axis represents duration (in s) of first head turn as measured from the onset of the sound.
