This study aims to examine the relationship between school maturity levels and speech and language development of children receiving preschool education. The correlational survey models was used to determine these relationships. The sample of the study consists of 44 boys and 58 girls who are studying in public schools in Meram district of Konya…

The Early Start Denver Model (ESDM) is an intervention program recommended for pre-schoolers with autism ages 12-48 months. The rationale for this recommendation is the potential for intervention to affect developmental trajectories during early sensitive periods. We investigated outcomes of 32 children aged 18-48 months and 28 children aged…

Investigates developmental change in inter- and intrahemispheric transfer of tactile information in two experiments with 74 and 77 subjects aged 4, 6, 10, and 20 years. Results indicate a developmental improvement in inter- and intrahemispheric transfer of tactile information. (RJC)

Developmental changes in the expression of superordinates in children's word definitions were studied with 96 elementary school students. Superordination increased significantly and changed qualitatively with age, although across grades children produced more superordinates for nouns than for adjectives or verbs. (SLD)

Describes a study to determine: (1) the relationship between age and mean length of utterance measured in morphemes (MLU) in a group of normally developing two- and three-year-old chidren; (2) the standard error of MLU; (3) the relationship between MLU and age; and, (4) the ability of MLU to predict children's grammatical development. (SED)

Investigated developmental change in symbolic representational ability by examining infants' imitation of vocalizations, words, visible motor actions, and nonvisible motor behaviors at ages 10, 13, 17, and 21 months. Results revealed a pattern of increasing imitation, supporting the view that a domain-independent representational capacity develops…

Two experiments examined toddlers' noun vocabularies and interpretations of names for solid and non-solid items. Results indicated that one side of the solidity-syntax-category organization mapping was favored. Seventeen- to 33-month olds do not systematically generalize names for solid things by shape similarity until they already know many…

Forty children each from nursery school, first grade, and third grade participated in a study of the use of symbolic mediators in the control of overt behavior of children with internal and external locus of control. Each child participated in three different verbal control tasks: a push-button task, a pounding-board task, and a serial-recall…

Forty-eight middle-income children, equally divided as to sex, looked at a sequence of animated films in which a pair of male figures underwent a change in facial affect. Three questions were posed: (1) Could a qualitative-structural analysis be applied to the kinds of explanations given by the children to account for changes in facial affect? (2)…

Early interventionists are accountable for the progress of children receiving their services. Technically adequate measures of the progress of individual children are needed. While the Early Communication Indicator (ECI) for infants and toddlers is one such measure, data to support its use are limited to a single research report. In this…

This study compared mother-child interactions and investigated how child verbal abilities interact with age to influence maternal scaffolding (teaching) styles in a group of 60 mother-child dyads in which the children were aged 3, 4, and 5 years (20 dyads in each of the 3, 4, and 5 year age groups). The mother-child pairs were filmed completing a…

This study examines ways in which children verbalize emotional experiences at successive age levels. Four groups of 16 boys and girls each drawn from the second, fourth, sixth, and eighth grades of a middle class private school in New York City were asked to describe happiness, sadness, love, anger, and fear. Raw protocols were scored according to…
