Dichotic and monotic interactions between VC's and CV's: Masking or articulatory constraints
Janet G. May, Robert Porter, Creighton J. Miller · The Journal of the Acoustical Society of America · 1980
Several reports by Haskins Laboratories' scientists [reviewed by Dorman, M. F., Raphael, L. J., and Liberman, H. M. (1979). Haskins Laboratories SRSR, SR-58, 105] suggest articulatory possibilities constrain the perception of VC1C2V sequences in which the (silent) closure interval varies in duration: for example, a VC1C2V sequence is perceived as a VC2V at short closure durations. It is argued that this phenomenon occurs because articulation-based perceptual decoding is constrained as is articulation: i.e., C1 cannot occur so soon before C2. However, the presentation procedure is like that which would be employed to investigate backward masking of VC1's by C2V's, and the question arises as to whether general auditory masking might explain the perceptual effect. The aforementioned studies reported results of some stimulus manipulations which argue against the involvement of such masking. The present study explores additional manipulations. Preliminary results suggest the situation to be somewhat more complex than might be supposed from either a masking or articulation-constraint point of view.
