The purpose of the experiment was to determine how language familiarity affects stuttering under delayed auditory feedback (DAF). In one condition we compared DAF interference in German-English bilinguals speaking their more and less familiar languages. A language familiarity effect was found: the bilinguals spoke faster and stuttered less under DAF when speaking their more familiar language. This effect was independent of both delay time and language spoken. Moreover, the slower rate in the less familiar language could not explain the language familiarity effect since instructing Ss to slow down their rate of speech decreased rather than increased their stuttering. A second condition showed that the language familiarity effect was not due to paying more attention to feedback in the less familiar language. Rather, practice or experience in producing the motor organization of speech seemed to underlie the effect of language familiarity.

Female Subjects

Twenty female subjects were required to select, by the method of fractionation, the delay interval judged by them to be one-half the duration of the standard delay interval with which it was paired. The signals judged were the delay intervals between the subjects' own production of the syllable /da/ and its return via delayed auditory feedback. Ten ascending and ten descending one-half judgments were obtained for each subject at each of tie standard delay intervals of 100, 200, 400, and 800 msec. The curves for the ascending, descending, and combined ascending-descending judgments, when plotted against delay intervals in physical time, were all nearly linear with a slight positively accelerated slope. A tentative scale of subjective delay time is described and its implications for evaluating the speech response to DAF as a function of time are noted.

Post Hoc

Five groups of 10 males and 10 females each, aged 5, 7, 9, 11, and 13 yr., recited a nursery rhyme under normal delay and 113-, 226-, 306-, 403-, and 520-msec delayed auditory-feedback conditions. Speaking rate and disfluency count changes from normal delay to each delayed auditory feedback condition were calculated as indicators of reaction to delayed auditory feedback. Analyses of variance and post hoc comparisons indicated that 5-yr.-olds reacted with greater change in rate at 520-msec. delayed auditory feedback than did older subjects. Five- and 7-yr.-olds were more disfluent at 413- and 520-msec. delayed auditory feedback than were older subjects. Sex differences were found in the 7-, 11-, and 13-yr.-old groups, using speaking rate as a measure of delayed auditory-feedback reaction. No significant sex differences were noted when disfluencies were used as indicators of delayed auditory-feedback reaction.

Delayed Auditory Feedback

This experiment was designed to test whether there are aftereffects on speech to delayed auditory feedback and whether the aftereffects, if any, are a function of the severity of disruption of speech under the feedback condition. Fifty-seven Ss, divided into three equal groups, were exposed to various combinations of delay time and intensity of feedback. Comparisons of pre- and post-sidetone responses revealed no evidence of aftereffects on speech. No relationship to induced severity of speech disruption was found.

This experiment investigates an apparent discrepancy in experimental measurements of the effect of texture predictability upon reading disruption under delayed auditory feedback (DAF). By measuring relative DAF decrement in three different ways, it is shown that the previous findings can be related; Fillenbaum's hypothesis of increased disruption by DAF with an increase in predictability of the material is rejected, less disruption being obtained after practice on a particular passage. Almost identical ratios of DAF rate divided by normal rate are found irrespective of the type of reading material and stage in practice. This has not been reported previously and suggests that behaviour under DAF may be related to behaviour under normal conditions by a multiplicative constant. These results are also consistent with the notion of limited channel capacity and the partitioning of attention between two sources of information.

Binaurally asynchronous delayed auditory feedback (DAF) was compared with synchronous DAF in 80 normal subjects. Asynchronous DAF (0.10 sec difference) did not yield results different from those obtained under synchronous DAF with a 0.20 sec delay interval, an interval characteristically resulting in maximum disruptions in speech.
