Research is reported which examined the effect of various factors on the frequency of phonological responses. Phonemic order and location of clusters within a syllable affected fusion. Initial stop-liquid clusters fused readily; final liquid-stop clusters rarely fused. Some subjects fused on most or all trials; others fused less frequently.…

An experiment is reported in which 25 listeners were presented with pairs of stimuli of equal duration, but differing in fundamental frequency, and were asked to decide which of the two stimuli was longer. (Author/RM)

An experiment tests conjectures that right ear advantage (REA) has an auditory origin in competition or interference between acoustically similar stimuli and that feature-sharing effect (FSE) has its origin in assignment of features of phonetically similar stimuli. No effect on the REA for acoustic similarity, and a clear effect of acoustic…

Investigates the phenomenon that subjects speaking under exposure to masking noise demonstrate decreases in oral sensory function and temporal reorganization of the articulatory pattern. The study attempts to measure the effects of this phenomenon under varying durations of exposure to auditory masking. (Author/NCR)

Boundaries in running speech are not all equally obvious acoustically. The research reported here is concerned with identifying the acoustic characteristics that trigger the listener's response to boundary signals. The eventual goal is to establish the relevance of the boundary to the syntactic and semantic structure of the message. (Author/TL)

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)
