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…

Assesses the relationship between production deficits and speech perception abilities. A categorical perception paradigm was administered to a group of communication disordered children and to a matched control group. Group results are tentatively interpreted as showing a moderate perceptual deficit in the communication disordered children of this…

Acoustic properties of retroflex consonants were determined and interpreted in terms of acoustic theory. The results are considered in relation to a quantal theory, auditory property detectors, and theoretical notions of markedness. (Author/TL)

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…

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)

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)

Argues that generative phonology is not predictive of phonological identification, thus preventing it from achieving descriptive adequacy and limiting its value in explaining human speech perception. The assumption that the unity of the morpheme must be expressed phonologically is rejected. (Author/EJS)

Adults and 4-year-old children were tested to determine whether the children were able to decode sets of familiar minimal pairs as well as adults. They listened to words spoken in a normal voice and a whisper. Indications were that the 4-year-old's perceptual mastery of English phonology is not yet complete. (SW)
