Reaction to another article in this issue, "How Not To Analyze the Syntax of Children" by Roger McCaig, pp. 612-18. (SW)

Different experimental techniques for empirical assessment of children's linguistic ability have produced conflicting evidence. A number of such contradictions are discussed, in the context of an analysis of the potential weaknesses, and consequent requirements, of both comprehension and production tasks. (A commentary by P. L. Harris appears on…

Presents a historical perspective on child language research, termed "stingy" because of the lack of financial and institutional support. Speaks of the pioneers and present researchers who study child language as men and women of unusual determination and commitment. (HTH)

In an analysis of the research literature on specific teacher behaviors which focused on oral language or speaking, no studies were found which could meet fully the criteria proposed for inclusion. Sources of problems lay in (1) the absence of an explicit theory of language underlying the study or series of propositions; (2) the failure to get…

Focusing on the question, "Can chimpanzees produce new sentences or merely sequences?" Terrace describes his efforts to teach the chimpanzee Nim to communicate through sign language. From his results, and the Gardners' experiments with Washoe, he concludes that no proof yet exists that chimpanzees can use language as humans do. (SJL)

Type/Token Ratios (TTRs) frequently fail to discriminate between children at widely different stages of language development, and may fall as children get older. Such effects are caused by a negative, though non-linear, relationship between sample size and TTR. Standardization of the number of tokens before computing TTRs is recommended.…

Discusses the shortcomings of the morpheme order approach in first and second language acquisition research, and proposes instead the notion of developmental sequence, drawing on examples from data on four German children learning English naturalistically. (Author/AM)

Twenty dyads--ten middle-class mothers and ten lower-class mothers and their two-year-old children--were videotaped in a play situation. Variables in speech and utterance production were examined for change across condition (awareness or ignorance of being observed) and across socioeconomic class within condition. The number of utterances was…
