Has anyone ever tried to reconcile the two apparently different
definitions of informational masking? One appears to relate to the
influence of stimulus uncertainty on detection and recognition, and the
other to more semantic and linguistic operations that confuse subjects
when responding to a speech target when the masker itself is
intelligible speech. It seems that the fields of psychoacoustics and
speech perception are currently engaged in efforts to to use one term to
mean two different things. Or are these definitions really different?
