Phonological fusion occurs when items such as PAY and LAY are presented separately to each ear and listeners report hearing PLAY. Input items that begin with a stop consonant (e.g. /p/) and a liquid (/1/ or /r/) fuse especially well. The present studies examined the effect of various factors on the frequency of fusion responses. Allophonic variation in the liquids (“trilled” versus plain) had no effect on fusion frequency. Phonemic similarity also had no effect; that is, when the input items differed in all phonemes (PAY and LED) they still fused. However, the phonemic order and location of clusters within a syllable did have a large effect:initial stop-liquid clusters fused readily (PAY/LAY yielded PLAY) while final liquid-stop clusters rarely fused (PEEL/PEED rarely yielded PEELED). Various fusion phenomena remained the same when tested in both identification and discrimination paradigms. Finally, fusion scores were not normally distributed over subjects; that is, some subjects fused on most or all trials, while others fused less frequently. |
