Do conjunction errors in auditory recognition imply feature migration?
It has recently been proposed that the feature values (e.g., pitch, duration, etc.) of tones are processed in separate perceptual channels and are later reintegrated to form the experience of a unitary percept. Patterns of errors in recognizing combinations of auditory features have been taken as failures of, and thus evidence for, an auditory feature-integration process. We outline an alternative interpretation of these effects based on similarity structure of the stimuli.
