Intensity Ratios

A study was made of the effect of the presentation order of delay/synchronous (DAF/SAF) intensity ratios on tapping performance under simultaneously presented synchronous and delayed auditory feedback. Comparisons were made between performances of groups who received either primarily positive or primarily negative DAF/SAF ratios in random order. Additional comparisons were made between subjects who received serially presented DAF/SAF ratios in an ascending series and those who were given the same stimuli in a descending DAF/SAF ratio series. It was found that, when synchronous and delayed auditory feedback are presented simultaneously at various DAF/SAF ratios, the presentation order influences the degree of performance disruption. It is concluded that the results of studies involving the use of simultaneously presented SAF and DAF should be interpreted in light of the stimulus presentation order.

Female Subjects

Twenty female subjects tapped on a tapping key to programmed visual pacing stimuli under synchronous auditory feedback, delayed auditory feedback, and decreased sensory feedback conditions and also to programmed auditory pacing stimuli under synchronous visual feedback, delayed visual feedback, and decreased sensory feedback conditions. Cross-modality matching procedures were employed to equate the perceptual magnitudes of the auditory and visual stimuli. Pattern duration and tapping key displacement variables were evaluated and it was noted that the relative perceptual magnitudes between pacing and feedback stimuli are important aspects determining the degree of alteration in keytapping motor performance under delayed sensory feedback. The data also indicated that increases in the intensity of tapping observed under delayed sensory feedback conditions were not due to the temporal distortion of the feedback but possibly to an absence of feedback at the moment of tapping.

Major Factors

Some of the major factors that might influence tapping changes induced by relatively short-term, pure tone delayed auditory feedback (DAF) were investigated. Stimulus frequency, subject, sex, sophistication, practice, physical fatigue, adaption to the task, and habituation to the task were considered. Only sophistication and habituation influenced performance significantly. The introduction of pure tone DAF within 5 dB SL, produced observable changes in tapping, thereby providing a sensitive means of extrapolating pure tone thresholds in a relatively objective manner.

Pure Tone Average

Three groups of 15 normal-hearing subjects were asked to simulate a hearing loss in one ear. Each subject was then tested on four measurements often used in determining the presence of pseudohypacusis (a comparison of the SRT to the pure-tone average, ascending vs descending pure-tone tests, the Stenger test, and pure-tone delayed auditory feedback). Results showed that as practice and sophistication on each of the procedures increased, there tended to be more improvement in the subjects' ability to “beat” some of the tests than others.

The Relationship

An experiment was conducted to examine the interrelationships between response-latency, perceived stimulus affect, and stimulus presentation order. Three groups of five Ss each responded to 100 pictorial and verbal stimuli along an ATTRACTIVE-UNATTRACTIVE affect dimension. Overt evaluative responses and response latencies were recorded on paper tape. The results indicated that the relationship between affect and response latency is an inverted U-shaped function with the attractive responses yielding significantly shorter latencies than either neutral or unattractive responses. The order in which stimuli are presented significantly affects both perceived affect and response times. A random order of stimulus presentation results in shorter latencies and greater perceived positive affect than the systematic arrangement of stimuli.

Pressure Changes

Modified instrumentation for pure-tone delayed auditory feedback (DAF) is described. This equipment, which achieves considerable simplification over previous designs, retains tapping-pressure changes as an indication of performance disruption under DAF. A specially constructed key unit serves to connect a pure-tone signal to an earphone through a tape recorder fitted with separate record and playback heads. The key-tapping unit also incorporates a pressure transducer (carbon granules capsule) which acts as one arm of a wheatstone pseudobridge. Hence resistance changes in the balance of the bridge are converted to stylus deflections on a graphic recorder.

Female Subjects

Thirty-two female subjects tapped on a felt-padded key to a programmed repetitive flashing visual signal under various conditions of pure tone SAF and DAF. Two SLs of sound, 20 dB and 60 dB, and seven conditions of auditory feedback were employed (two SAF and five DAF conditions). Data were obtained concerning the relationships among tapping rates, delay times, and SLs of auditory signals.

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.
