A precedence effect in the processing of verbal information

When a brief sound is monitored in a sound-reverberating room, it is immediately followed by numerous echoes bounced off the walls and ceiling. Only the first sound to arrive at the ears appears to be used in its localization. This is generally referred to as the precedence effect. If the processing of verbal information is seen as a reverberating system (after Hebb) and rehearsal as the manifestation of the echoes, then an analogous precedence effect can be empirically demonstrated. Such an analogy not only helps explain previously uninterpretable data but also generates a very unique prediction that was confirmed by experimental data. The theoretical implications of the analogy are also discussed.
