This study constitutes the beginning of a longitudinal investigation of phonological development of four children from birth to 2 years. Little variation was found in mean fundamental frequency. Duration, within-utterance range and variability did show developmental change. (RM)

The nature of the task of defining words by means of other words and the development of language responses (from children aged four to seven) are discussed in terms of a linguistic analysis of the definitional form and its semantic relations. (Author/RM)

To ensure reliable language data for research there is a need for experiments eliciting acceptability judgments. Experimental data are discussed to show that evaluation of a sentence may be affected by the sentence with which it is paired. Sentences with similar deviances should be presented as a set for evaluation. (CHK)

This article discusses research into the question of whether the expectation of hereditary factors in man's unique form of communication is supported by any evidence. The research is divided into three broad categories, dealing with voice, with speech, and with language. (CFM)

A survey of the historical developments of linguistic theories relating to aphasia. Some topics covered are: the breakdown of language as opposed to acquisition of language; functional structuralism basic to neurolinguistics; analysis of language disorders; neurolinguistics--models and typology; aphasia and agraphia. (Text is in French.) (AMH)

Attempts to answer several questions posed by researchers in agraphia. The questions concern analysis of errors in sensory aphasia; a typology of sensory agraphia; a possible relationship between sensory agraphia and sensory aphasia; and questions of a neurolinguistic order and those of a purely linguistic order. (Text is in French.) (AMH)

A discussion of social factors in language usage in the framework of sociolinguistics as defined by Labov. Some topics considered are: language as social practice, elements of a socio-differential phonology of /r/, variation in formal style, and an outline of a sociology of variation. (Text is in French.) (AMH)

The prosodic features of maternal speech to infants were measured quantitatively in a tonal language, Mandarin Chinese, to determine whether the features were similar to those observed in nontonal languages such as English and German. The pattern of results for Mandarin motherese was similar to that reported for other languages. (PCB)

Argues that two current receptions of Plato's rhetorical theory that either (1) leave him out, or (2) claim he rejected rhetoric, have serious consequences for contemporary rhetoric and composition studies. Discusses critics who support a third position and claims this position reconnects rhetoric with thinking rather than mere formulizing. (NH)

Investigates the perceptual representation of speech by young infants using a modification of the high-amplitude sucking (HAS) procedure. Results demonstrate that the infants' representations preserve detailed information about both the consonantal and vocalic portions of the syllables. (Author/RWB)

The Reporter's Test (DeRenzi and Ferrari, 1978), which investigates the expressive abilities of aphasics, is proven to be useful, through its use in two studies of features of Welsh, for sociolinguists studying language features. The test has great capacity for predicting syntactic forms and eliciting casual styles of speech. (Author/CB)

Methods from Item Response Theory were used to assess the degree to which a French-Canadian translation of the Job Descriptive Index, a job satisfaction inventory, provided measurement equivalence across source and target languages and cultures. The procedures were found to be applicable to cross-language research. (Author/LHW)

An examination of concerns about and suggestions for revising the ACTFL (American Council on the Teaching of Foreign Languages) Oral Proficiency Guidelines indicates that confirmatory empirical research and determination of the relative absence or presence of components are needed. (CB)

Asserts that many aspects of the second-language learning and teaching process are not amenable to experimentation at the present time and that case studies, that is, studies of the individual learner, teacher, or classroom, are valuable as precursors to experimentation. (Author/SED)

A study of the order of acquisition and fossilization of several French forms by anglophone students focused on the intonative aspect of interlanguage and the transfer of learning from one language to another. (MSE)
