Listeners� ability to detect a fixed-frequency tone added to randomly drawn multitone maskers is poor even when the maskers have little energy in the frequency region of the signal. One potential explanation of such �informational masking� is that observers fail to attend exclusively to the frequency channel conveying information regarding the presence of the signal. The results from several informational masking studies will be reviewed; with an emphasis on the usefulness of linear models in capturing individual differences in sensitivity. Additionally, experiments evaluating the potency of previews and post-views of the uncertain masker will be considered.
