“…This will be referred to as the 4-2 pattern; it has been used in previous DAF tapping studies (e.g., Karlovich & Graham 1966, 1967Ruhm & Cooper, 1962), in which it showed more marked effects than did simpler patterns, such as groups of 3 (see Experiment 2 in the present paper for confirmation) or a 3 -1 pattern. 1 The pattern was tapped at two rates; the 250-msec rate had intertap onset intervals of 250 msec within a group (within-group interval) and 500 msec between groups (betweengroup interval), whereas the 400-msec rate had a within-group interval of 400 msec and a between-group interval of 800 msec.…”

“…One measurement of impairment used in DAF tapping studies (e.g., Chase, Harvey, et al, 1961;Ruhm & Cooper, 1962) is counting or number errors: how frequently groups in a pattern are performed with an incorrect number of taps. To calculate such measures, it is necessary to have a criterion for which taps should be considered part of a single group.…”

“…Ruhm and Cooper (1962) reported that a 200-msec delay gave more impairment in a tapping task than did a 100-, 300-, or 400-msec delay, but tapping rate was not controlled. Howell et al (1983) found maximal impairment (using a timing measure) for error-free Morse code transmission at a delay near 200 msec.…”

“…The impairment demonstrated under DAF includes decreased speech rate, increased loudness, and dysfluencies of various kinds, including syllable repetitions and vowel prolongations. Other tasks are also impaired under DAF, including music performance (Finney, 1997;Havlicek, 1968), Morse code production (Howell, Powell, & Khan, 1983;Lee, 1951;Yates, 1965), clapping (Kalmus, Denes, & Fry, 1955), and rhythmic finger tapping (Chase, Harvey, Standfast, Rapin, & Sutton, 1961;Finney, 1999;Karlovich & Graham, 1966;Lee, 1950;Ruhm & Cooper, 1962). The reported impairment in these other domains is qualitatively similar to that of speech, including a slowing of rate and errors of insertion or repetition; many researchers of DAF (e.g., Chase, Harvey, et al, 1961;Howell et al, 1983;Lee, 1950;MacKay, 1987) have addressed their proposals to both speech and other forms of behavior, such as tapping.…”

Delayed auditory feedback (DAF) impairs performance in speech, music, and tapping, with maximal impairment in speech occurring at a delay of about 200 msec. This critical interval has played a central role in many explanations of the DAF effect, including both closed-loop feedback explanations and alternative proposals. We investigated the nature of the critical interval in rhythmic tapping-in particular, whether the critical interval has a constant value or is dependent on performance rate. Three experiments in which a synchronization-continuation paradigm was used consistently showed that the critical interval shifted with different tapping rates, with maximal impairment occurring when the delay approximately equaled the tapping rate. We address the implications of these results for theories of DAF.
