Abstract:In two experiments, tape-recorded strings of seven recall digits were preceded by a redundant stimulus prefix containing either one or three digits. The prefix and recall digits (1) were articulatorily continuous, or (2)were made discontinuous by tape-splicing, or (3)were made discontinuous by deliberately spoken prosodic contour. Subjects were instructed to ignore the redundant prefixes and report only the recall digits. The main results were: (1)Compared to strings preceded by no prefix, all prefix conditions reduced recall. (2)Three-digit prefixes reduced recall less than one-digit prefixes. (3) In most cases, spliced prefixes reduced recall less than intact prefixes. Acoustic waveform measurements are presented to provide a partial account for the results.
