Schematic illustration of the Test of Attention in Listening (TAIL) and auditory processing tasks.

<p>For TAIL, Backward and Simultaneous Masking, one example trial of stimulus presentation is plotted. For Frequency Discrimination, two trials are plotted. Abbreviations: In TAIL, F stands for frequency, L for location, S for same, and D for different. In auditory processing tasks, BM0 is Backward Masking with no silence gap between the target tone and the noise masker, BM50 is Backward Masking with a 50-ms silence gap between the target tone and the noise masker, SM is Simultaneous Masking with no spectral notch around the target tone, SMN is Simultaneous Masking with a spectral notch around the target tone, FD is Frequency Discrimination with a fixed standard tone, and FDR is Frequency Discrimination with a roving standard tone.
