Traditionally, amplitude, duration and F0 have been proposed as independent cues to stress [D. Fry, J. Acoust. Soc. Am. 27, 765–768 (1955)]. However, there is psychoacoustic evidence that the perception of loudness depends on duration [B. Scharf, ‘‘Loudness,’’ in HandbookofPerception, edited by E. C. Carterette and M. P. Friedman (Academic, New York, 1978), Vol. 4, pp. 187–242]. Beckman proposed the intensity integral as a more appropriate cue to stress than either amplitude or duration alone [M. Beckman, StressandNon-stressAccent (Foris, 1986)]. The present study tested the perceptual integrality of duration and amplitude using Garner’s paradigm [W. R. Garner, TheProcessingofInformationandStructure (Erlbaum, Hillsdale, NJ, 1974)]. Preliminary results suggest that duration and amplitude are integral. Further, the integrality is asymmetric: Variation in duration interfered with responding to amplitude to a greater extent than amplitude variation interfered with responding to duration. These findings suggest that both duration and energy (the integral of amplitude over duration) may serve as auditory cues to stress. [Work supported by NIDCD Grant Nos.
