Stylistic Variation at the "Single-Word" Stage: Relations between Maternal Speech Characteristics and Children's Vocabulary Composition and Usage

In this study we test a number of different claims about the nature of stylistic variation at the "single-word" stage by examining the relation between variation in early vocabulary composition, variation in early language use, and variation in the structural and functional propreties of mothers' child-directed speech. Maternal-report and observational data were collected for 26 children at 10, 50, and 100 words, These were then correlated with a variety of different measures of maternal speech at 10 words, The results show substantial variation in the percentage of common nouns and unanalyzed phrases in children's vocabularies, and singficant relations between this variation and the way in which language is used by the child. They also reveal singficant relations between the way in whch mothers use language at 10 words and the way in chich their children use language at 50 words and between certain formal properties of mothers speech at 10 words and the percentage of common nouns and unanalyzed phrases in children's early vocabularies, However, most of these relations desappear when an attempt is made to control for ossible effects of the child on the mother at Time 1. The exception is a singficant negative correlation between mothers tendency to produce speech that illustrates word boundaries and the percentage of unanalyzed phrases at 50 and 100 words. This suggests that mothers whose sprech provides the child with information about where new words begin and end tend to have children with few unanalyzed. phrases in their early vocabularies.     

An Interactive Methodology for ‘Empowering’ Students to Deal with Controversial Environmental Problems

After a short introduction to the Italian context relating to science teachers’ training and updating course we explain the motives that led us to produce educational material based on interactive methodologies (role‐playing) and to present it to in‐service teachers during updating courses. The role‐playing activities that we prepared draw from specific historical and geographical situations in order to face the problems of global environmental issues, such as, for example, water resources management, waste‐disposal, reforestation techniques. Some observations on the didactic effect of our proposals and on the importance of encouraging a change in the teachers’ way of thinking are presented. The latter is a prerequisite for a correct use of the educational material supplied. This means introducing a problematic concept of scientific knowledge and stimulating new attitudes to establish less hierarchic inter‐relations in class.     

Social routines,pragmatic schemas,and schemes in how children distribute objects between the ages of three and six

Past research on social marking and pragmatic reasoning schemas suggest that cognitive processing modes are first elaborated by children when are carying out regulating social routines in the course of which they learn to produce the responses that satisfy the demand of their environment. The data of five experimental studies with 3–6 year old children, for object distribution tasks, are reported here. The data of the three first experiments show that the social routines evoked by the objects to be processed have a dual effect, influencing both the representation of the partition to be made, as well as the procedures used to make them. The data of the two last experiments seems to attest that, in training situations, the utilization of routine-evoking tasks promotes the construction of more general schemas, by the attribution of an operative meaning to the linguistic expressions used to characterize the states to be attained, and the transformations to be applied in order to attain them.     

Earned-secure attachment status in retrospect and prospect

Past research with the Berkeley Adult Attachment Interview demonstrates that retrospectively defined earned-secures (who coherently describe negative childhood experiences) parent as effectively as do continuous-secures (who coherently describe positive childhood experiences), but manifest liabilities in the form of depressive symptomatology. This article presents data from a 23-year longitudinal study that replicate and extend prior research, testing a key premise that earned-secures so defined actually have a history of insecure attachments that change over time and/or endure consistently harsh or ineffective parenting in their youth. Discrepant with assumptions, retrospective earned-secures were not more likely than continuous-secures to have been anxiously attached in infancy and were observed in childhood and adolescence to have encountered among the most supportive and structured maternal parenting in a high-risk sample. Prospectively defined earned-secures (operationalized using participants' infant attachment classifications) did indeed go on to have success in their close relationships, many without reporting relatively high levels of internalizing distress in adulthood.     

‘The communities we live in’: providing meaningful contexts for the application and generation of knowledge through service in Uganda

Abstract

If service-learning is to fulfil its potential to contribute to meaningful social change, scholars and practitioners must consider how service might foster a dynamic relationship between knowledge, the learner and the community. This paper challenges modernist conceptions of knowledge as a ‘commodity’ that can be delivered and consumed, and instead identifies service to the community as a meaningful context for learners to interact with knowledge in a coherent framework for the explicit purpose of individual and social change. The Preparation for Social Action programme in Uganda is offered as an example in which relationships between knowledge, learners and the community can be examined. Findings from an analysis of curricular materials, participant observation and interview and focus-group data collected from its local instructors and administrators are discussed.     

A longitudinal confirmatory factor analysis of indirect and physical aggression: evidence of two factors over time?

The purpose of the present study was to examine whether indirect aggression was distinct from physical aggression across developmental periods. Participants were 3,089 Canadian children aged 4 to 7 years (Time 1), 6 to 9 years (Time 2), and 8 to 11 years (Time 3). Confirmatory factor analysis using an accelerated longitudinal design confirmed a 2-factor model that was stable across cohorts, time, and sex. The longitudinal predictive links between indirect and physical aggression were also examined in a path analysis. Findings did not support the notion that maturation is associated with changes in the ways children aggress but rather suggest that children are consistent in the type of aggression they use over time, whether it be indirect or physical.     

German children's comprehension of word order and case marking in causative sentences

Two comprehension experiments were conducted to investigate whether German children are able to use the grammatical cues of word order and word endings (case markers) to identify agents and patients in a causative sentence and whether they weigh these two cues differently across development. Two-year-olds correctly understood only sentences with both cues supporting each other—the prototypical form. Five-year-olds were able to use word order by itself but not case markers. Only 7-year-olds behaved like adults by relying on case markers over word order when the two cues conflicted. These findings suggest that prototypical instances of linguistic constructions with redundant grammatical marking play a special role in early acquisition, and only later do children isolate and weigh individual grammatical cues appropriately.     

Behavior of Infants with Iron-Deficiency Anemia

This study tested the hypothesis that infants with iron-deficiency anemia show behaviors, such as increased proximity to caregivers, increased wariness or hesitance, and decreased activity, that could contribute to “functional isolation.” The behavior of 52 Costa Rican 12- to 23-month-old infants with iron-deficiency anemia was contrasted with that of 139 comparison group infants with better iron status during free play and mental and motor testing and in the home. Infants with iron-deficiency anemia maintained closer contact with caregivers; showed less pleasure and delight; were more wary, hesitant, and easily tired; made fewer attempts at test items; were less attentive to instructions and demonstrations; and were less playful. Adult behavior also differed. The results indicate that iron-deficiency anemia in infancy is associated with alterations in affect and activity, suggesting that functional isolation is a useful framework for understanding poorer developmental outcome in iron-deficiency anemia, the world's most common single nutrient deficiency.
