Process Interaction

Several investigations have reported problems in demonstrating for vowels the phenomena of backward masking and right ear advantage so easily demonstrated for consonants. An experiment is reported on the dichotic backward masking (BM) of acoustically similar and dissimilar sets of vowels in consonant-vowel syllables. The results suggest that increasing perceptual difficulty by varying the acoustic similarity of the stimulus set augments BM. A second experiment showed that the right ear advantage (REA) was augmented by manipulating the acoustic similarity of the stimulus set and by decreasing intelligibility through the addition of noise. This and other evidence was employed to ascribe variations in both REA and BM to the interaction of perceptual processing time with information decay in precategorical acoustical storage. It is argued that this process interaction underlies statistical interactions in dichotic data which show that variations in difficulty (discriminability, noise addition, brain deterioration) affect most adversely the least favoured items (those presented earlier, those on the unattended ear, those on the left ear).

Subject Comparison

56 right-handed adults (23 men, 33 women) with IQs ranging from 79 to 140 on the Quick Test each performed on two dichotic tests, one with digital input, one with tonal input. The average magnitude of the right-ear advantage for digits was comparable to that of the left-ear advantage for tones, but there was greater between-subject variability with tonal input than with digital input. Ear advantage with digits was unrelated with ear advantage with tones, and high intelligence was not associated with clearly opposite directions of ear advantage for the two types of test material. The results were discussed in terms of hemispheric specializations, as well as the reliability and validity of the dichotic ear effects.

It is well documented that the majority of individuals with normal hearing have a right ear advantage for dichotic speech material. There is evidence, however, that individuals with flat sensorineural hearing loss demonstrate a left ear advantage after they have used amplification on the left side. The present study examined whether these findings could be extended to a population with high-frequency hearing impairment. The subjects were administered dichotic consonant-vowel syllable tests prior to a monaural hearing aid fitting, and the tests were repeated after 1 month and again after 6 months of hearing aid use. The results revealed a group right ear advantage prior to the hearing aid fitting, although there was considerable individual variability. No consistent changes in the test scores were shown to be associated with monaural hearing aid use in either the right ear or the left ear.
