Suggests that Kuhn's study reported in this issue (PS 524 345) offers insight into how people make casual inferences, and raises important questions about these processes. (JW)

Responds that questions of study by Kuhn and others (PS 524 345) in this issue were motivated by concerns about the role of scientific thinking in general thinking, not in development of scientific reasoning. Study was meant to increase understanding of role of strategies in development, not provide definitive explanation of how strategies fit…

Examined impact of gender and life-cycle stage on three components of work-family conflict using sample of 3,616 respondents. For men, levels of work-family conflict were moderately lower in each successive life-cycle stage. For women, levels were similar in two early life-cycle stages but were significantly lower in later life-cycle stage.…

This study found that, although normally hearing children produced more communicative acts than 9 agemates (age 14-34 months) with severe hearing impairments, the hearing-impaired children produced more than hearing children matched for verbal language age. Results reveal that preverbal hearing-impaired children make significant strides that can…

Suggests that the central focus of the article by Raver and Leadbeter (PS 521 712) in this issue is the ways individuals know. Examines two ways of knowing, verbal responses to questions and action without verbal response; and outlines a four-level developmental sequence of knowing that develops from one's own knowing to having a perspective on…

Eight 20- to 26-month-old children were exposed to 4 novel nouns in a game context over several weeks to determine whether, when, and in what ways the children would use them beyond their original linguistic forms. The majority were productive in their use of the nouns, indicating that the grammatical category for noun is operational by age 2.…

Examined the impact of an educational intervention on knowledge of speech-language development among 66 caregivers of children. An educational handout containing information about basic speech and language development milestones was provided to the intervention group. Results of pre- and posttests indicated that the intervention group increased…

Two experiments studied preschool children's ability to infer numerosity from correspondence between two sets. Found that children were able to make inferences as early as three years of age. However, differences between the two conditions suggest production deficiencies in young children's use of counting as a problem-solving strategy when they…

This study of four young children with developmental delay involved building verbal routines through repeated interaction with the same picture book, followed by generalization sessions. The intervention increased generalized mean length of utterance in children in the first stage of language development more than in children in a later language…

Questionnaires assessing perceived competence, perceived control, competitive trait anxiety, and motivational orientation were completed by 108 boys. Additionally, 12 coaches were observed for 2 games in order to record coaching behaviors during competition. The model tested showed that both coaching behaviors and children's trait anxiety causally…

This study tested the hypothesis that pretreatment level of play would predict the rate of increase in prelinguistic, intentional requesting during prelinguistic communication intervention of 8 children (ages 21 to 30 months) with developmental disabilities. A positive relation was found between amount of transitional or symbolic play at baseline…

This longitudinal study investigated development and individual differences in exploration and play during infancy and toddlerhood among 34 children. Found that measures of developmental level, such as pretend play level and meaningful sequence, showed a significant increase between age 19 months and 30 months. (MDM)

Describes a computerized assessment instrument to assess development in youngsters 2 to 7 years of age, based on the 12 developmental scales of Arnold Gesell. (SR)

This article describes the language development in a left-handed young child with a left middle cerebral artery infarction. Patterns of development observed between 36 and 60 months of age are described as a transient jargon or fluent aphasia possibly resulting from initial reliance on an uninjured right hemisphere.

Postural control was evaluated in 91 autistic, 166 normal, and 18 mentally retarded children using a computerized posturographic procedure. In comparison to normal children, the autistic subjects were less likely to exhibit age-related changes in postural performance, and postures were more variable and less stable. (Author/JDD)
