Two experiments were conducted to determine whether the auditory feedback monitoring system for speech is operative in children between two and three years of age. The procedure involved a 200 msec delay in the auditory feedback of the subject’s speech. Bilateral signal presentation was used for the synchronous (SAF) and delay (DAF) conditions. Phonation time scores under DAF and SAF conditions were compared. In Experiment I, 10 subjects, ages 2 years, 4 months to 2 years, 11 months, followed a standard object naming task. Speech samples obtained from a younger group of 5 subjects in Experiment II, ages 1 year, 9 months to 2 years, 2 months, consisted of all verbal responses which occurred under both DAF and SAF conditions. The results of Experiment I provide evidence that the auditory feedback monitoring system for speech is operative in this age group. The speech of the younger subjects in Experiment II was not strongly affected by the time delay in auditory feedback. The results of the present experiments, together with findings obtained in an earlier study with four- to nine-year-old subjects, suggest that older children show greater DAF effects than younger children.

Speaking Task

25 male stutterers and 25 male non-stutterers matched by age and speaking task, read or recited under conditions of normal and 113-, 226-, 306-, 413-, and 520-msec. delayed auditory feedback. Disfluency counts were correlated with delayed auditory feedback reactions which were changes in disfluencies under delay conditions. Pearson product-moment correlations were negative and significant for the combined group of stutterers and non-stutterers under all delays used. Correlations for stutterers were negative and significant for 113, 226, 306, and 413 msec. delay. For the total group of non-stutterers, all correlations were negative and significant. Correlations for age groups within the stuttering and non-stuttering groups were also presented.

Auditory Feedback Control

Vocal cry samples of 20 normal newborn infants were recorded under two test conditions: synchronous auditory feedback and a 200 msec delay in auditory feedback (DAF). Averages for cry duration, pause time, and maximum sound pressure level were obtained for 16 of the 20 subjects. An analysis of variance showed significant effects for cry duration and amplitude (p < 0.05) but not for pause time. Subjects tended to decrease the average duration of cry bursts by more than 100 msec during the DAF test conditions. The resus, while not conclusive, indicate that cry behavior may be under closed-loop auditory feedback control. It is suggested that the auditory monitoring of cry behavior be further investigated by the use of several delay times. If the magnitude and character of changes in crying behavior show consistent variation as a function of delay time, more persuasive evidence for an auditory feedback monitoring system will have been adduced.

Competition Hypothesis

The Stroop phenomenon has recently been explained by two contrasting approaches, the perceptual conflict and the response competition. This experiment was designed to evaluate the two different explanations. 24 undergraduates were tested on the three sets of Stroop stimuli while hearing their verbal responses under delayed auditory feedback and under normal feedback. Delayed feedback produced differential response decrements across Stroop conditions. The findings supported predictions of the response-competition hypothesis and disconfirmed those of the perceptual-conflict hypothesis.

Repetition Task

There is a controversy in the literature concerning the effects of delayed auditory feedback (DAF) on the speech of subjects of varying ages, In the current experiment the subjects were five-year-olds, eight-year-olds and adult speakers who performed a sentence repetition task under: 0-delay, 250, 375, 500, and 625 msec of amplified delayed auditory feedback. All subjects performed the task under normal rate instructions and under instructions to speak as rapidly as possible. A developmental pattern emerged, with the youngest children significantly more affected by the DAF than the older children or the adults. There was only weak evidence for a critical delay interval that varied according to age of the subjects. Rate instructions had essentially no effect on the DAF or age patterns.

Delay Times

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.
