Abstract

Two experiments using dichotic listening measure the priming effect produced on the detection of a semantically-defined target word in an attended list of words by a lexically identical word presented to the opposite ear with an attenuation of 12 dB . Experiment 1 embeds the prime in unattended continuous speech and finds a 21-ms priming effect, but only when the voices of the two messages had different pitch ranges. This priming effect did not vary with word frequency. In Experiment 2 the prime was part of a list of isolated words played to the unattended ear. It found a 94-ms priming effect when there was no pitch-range difference between the two messages. This priming effect was larger for high-frequency words than for low. These results extend recent findings by Rivenez et al. (2006) and demonstrate the importance of factors that influence perceptual organization in determining the extent to which unattended messages can be processed
