Reports on research into perceptuo-motor control in a converse experimental situation, in which subjects were required to utter a repetitive sequence of syllables immediately prior to identifying syllables presented auditorily. Results support the notion of a unitary mechanism that processes information about certain consonant features during…

The selective tuning of feature detectors sensitive to the acoustic information relevant to the assignment of distinctive phonetic feature values was investigated with a contingent adaptation paradigm. (Author/RM)

Reports a study which shows that subjects can make discriminative judgments of a speaker's height and weight from his tape recorded speech. This ability is not altered by the filtering of the speech signal. (PMJ)

Reports a study showing that subjects can make discriminative judgments about a speaker's sex and race from his tape-recorded speech. Filtering the speech signal adversely affects race but not sex identification. Listener accuracy and confidence for sex judgments are greater than for race judgments. (PMJ)

Stampe's (1969, 1973) hypotheses regarding innate mental phonological processes are tested against some of the extant data on speech perception. (AM)
