ABSTRACTA description is given of the CHILDES/BIB database, its contents, and its relationship to the CHILDES database. CHILDES is a depository of child language corpora, and the publisher of CHAT (a transcription manual), and CLAN (an electronic package for child language research). CHILDES/BIB is an electronic bibliographic database that is an autonomous unit of CHILDES.

ABSTRACTType/Token Ratios have been extensively used in child language research as an index of lexical diversity. This paper shows that the measure has frequently failed to discriminate between children at widely different stages of language development, and that the ratio may in fact fall as children get older. It is suggested here that such effects are caused by a negative, though non-linear, relationship between sample size (i.e. number of tokens) and Type/Token Ratio. Effects of open and closed class items are considered and an alternative Verbal Diversity measure is examined. Standardization of the number of tokens before computing Type/Token Ratios is recommended.

Abstract. On 9 October 1963 a catastrophic landslide suddenly occurred on the southern slope of the Vaiont dam reservoir. A mass of approximately 270 million m3 collapsed into the reservoir generating a wave that overtopped the dam and hit the town of Longarone and other villages nearby. Several investigations and interpretations of the slope collapse have been carried out during the last 45 years, however, a comprehensive explanation of both the triggering and the dynamics of the phenomenon has yet to be provided. In order to re-evaluate the currently existing information on the slide, an electronic bibliographic database and an ESRI-geodatabase have been developed. The chronology of the collected documentation showed that most of the studies for re-evaluating the failure mechanisms were conducted in the last decade, as a consequence of knowledge, methods and techniques recently acquired. The current contents of the geodatabase will improve definition of the structural setting that influenced the slide and led to the the propagation of the displaced rock mass. The objectives, structure and contents of the e-bibliography and Geodatabase are indicated, together with a brief description on the possible use of the alphanumeric and spatial contents of the databases.

ABSTRACTHow do children develop the mapping between prosody and other levels of linguistic knowledge? This question has received considerable attention in child language research. In the present study two experiments were conducted to investigate four- to five-year-old Mandarin-speaking children's sensitivity to prosody in ambiguity resolution. Experiment 1 used eye-tracking to assess children's use of stress in resolving structural ambiguities. Experiment 2 took advantage of special properties of Mandarin to investigate whether children can use intonational cues to resolve ambiguities involving speech acts. The results of our experiments show that children's use of prosodic information in ambiguity resolution varies depending on the type of ambiguity involved. Children can use prosodic information more effectively to resolve speech act ambiguities than to resolve structural ambiguities. This finding suggests that the mapping between prosody and semantics/pragmatics in young children is better established than the mapping between prosody and syntax.

ABSTRACTWith the increasing use of computers in language research, there is a need for caution concerning several new issues of data accountability. This paper presents four principles for archive-based language research: Maximum Readability and Minimum Bias; Consistent Encoding for exhaustive computer search; Systematic Contrastiveness; and Data Comparability in elicitation, transcription and coding. These and related principles are illustrated by examples from existing computer archives, and strategies are suggested for minimizing detrimental effects of violations. Finally, the paper describes some implications of the principles for properties of a field-wide and international standard of transcription of language data.

The Relationship

ABSTRACTI first outline three major developments in child language research over the past forty years: the use of computational modelling to reveal the structure of information in the input; the focus on quantifying productivity and abstraction; and developments in the explanation of systematic errors. Next, I turn to what I consider to be major outstanding issues: how the network of constructions builds up and the relationship between social and cognitive development and language learning. Finally, I briefly consider a number of other areas of importance to a psychologically realistic understanding of children's language development.

Single Approach

This book is an excellent introduction to the field of child language development. It demonstrates the need for both a theory of language development and reliable speech and comprehension data in child language research. As Foster-Cohen states in the preface to the book, the adoption of only a single approach, as opposed to a combination of different approaches, is unlikely to lead to a productive understanding of child language acquisition. The book successfully adopts the perspectives of both the empiricist and the rationalist traditions in its treatment of key issues.
