Lastly, even if we are truly better at discriminating noise duration in silence than silence duration in noise, it does not follow that “spectral changes whose response in the auditory nerve is mainly onset of firing are much more perceptually salient than those producing an offset” (Bladon 1986:5). Offset of firing in the auditory nerve occurs in both types of stimuli, noise bursts and gaps. If the time lag between voice offset and onset (gap) or voice onset and voice offset (noise burst) is used to establish duration, an inherent difficulty in pinpointing voice offset should render the duration of both types of stimuli equally difficult to gauge. Bladon’s principle therefore does not explain the data provided by Tyler et al.; nor do the data of Tyler et al. illustrate Bladon’s principle. However, other kinds of evidence may support the notion of on/off response asymmetry. For example, experiments on the reaction time (RT) to the onset vs. offset of stimuli may indicate an existence of such an asymmetry. But, while there have been numerous studies on RT for the onset of stimuli, few experiments have been carried out in which RT to offset is measured. In by far the most extensive such study to date, testing 60 subjects, Rammsayer (1998) found that for white noise stimuli at both 65 and 90 dB, onset reaction times were significantly faster than were offset reaction times. If these findings are an indication that there is such a thing as on/off response asymmetry, its cause is still unclear. One might speculate that it is related to the findings of Delgutte (1982) and that it should be seen as a consequence of short-term adaptation. If this is the case, the principle may provide some indication of the degree to which neural discharge rates can be translated into salience. To summarise, Bladon attributes the rarity of preaspiration to properties of the auditory nerve, in essence to the absence of non-adapted neural activity at the onset of preaspiration. However, non-adapted neural activity is not a prerequisite for auditory robustness, and there is little evidence that non-adapted neural activity gives significant returns in terms of auditory salience. Thus, although there may be some perceptual benefits from non-adapted neural activity, this approach exaggerates the significance of neural discharge rates, essentially turning them into a measuring stick for perceptual salience. Also, Bladon underestimates the – 40 –
number of languages that possess sequences of aspiration and stop (be they called preaspiration or hC clusters). Two phonetically similar sound sequences that differ only in terms of phonological interpretation should not respond in different ways to the same auditory constraint. Such constraints must be applicable to sound patterns, irrespective of how these sound patterns are organised phonologically. To conclude, the auditory constraints proposed by Bladon are not as powerful as he claims, and can hardly be wholly responsible for the apparent rarity of normative preaspiration. Nevertheless, they should be given serious consideration, since they indicate that postaspiration is better in terms of perceptual discriminability than is preaspiration. Possibly, this has a bearing on the outcome of a process of sound change in that postaspiration has a perceptual advantage over preaspiration. – 41 –
