Describes the spontaneous development of 13 symbolic gestures in a normal infant from 12 to 17 months. Sixteen additional symbolic gestures were purposefully taught. Vocal development was advanced, indicating that gesturing is not necessarily related to poor vocal skills. Data support the hypothesis that sensorimotor behaviors are natural…

Argues that none of the conventional methods for assessing attachment meet all criteria. Describes development of a 100-item sort for assessing secure attachment in toddlers, closely tied to Bowlby's control systems model of attachment. Evaluates the Q-sort in terms of criteria for valid thoery-based assessments that have applicability beyond this…

Quantitatively describes the gait development of a group of African children to determine how pattern changes would relate to growth and maturation. A total of 65 children from the Gusii tribe of southwestern Kenya, ranging in age from 13 to 69 months, were selected for study. (Author/RH)

In families with two working parents, fathers make important contributions to children's early language skills. Results from a new study by FPG Child Development Institute show that children whose fathers' vocabulary was more varied when they were two, had greater language skills at age three. Mother's vocabulary was not found to have a…

This volume explores the key developmental transitions that take place as 1- to 3-year-olds leave infancy behind and begin to develop the social and emotional knowledge, skills, and regulatory abilities of early childhood. Leading investigators examine the multiple, interacting factors that lead to socioemotional competence in this pivotal period,…

Between their second and fifth years, young children learn approximately 15 new words a day. For every word the child hears, he or she must choose the correct referent out of an infinite set of candidates. An important problem for developmental psychologists is to understand the principles that limit the child's hypotheses about word meanings. A…

Children ages 1 1/2 to 3 years were tested to determine their comprehension of the terms "in,""on," and "under." It was found that children who listened to a pretest story involving the objects to be used in the study showed markedly better comprehension of the terms than children not exposed to the pretest activity.…

Studies social play and social and solitary pretend play in well-acquainted toddlers aged 14-38 months in order to describe a sequence of progressively more complex social pretend play forms. Results indicate that social pretend play forms emerge later than comparable solitary pretend and social play forms. (RJC)

This case study examined prosodic use in a normally developing child between the ages of 20 and 46 months. Conversational repairs were elicited to examine prosodic stress. Fundamental frequency, intensity, and duration of syllables were measured. Although the subject could repair stress errors, a clear pattern of the development of acoustic cues…

Types of utterances (with locative action utterances specifically differentiated) were evaluated in a language-impaired child tracked between one year, six months and three years of age. Comparison with utterances in other children suggests the importance of such a fine-grained analysis in detecting semantic properties of child language…

This study examined phonological changes in the conversational speech of children between the ages of 2 and 3 years. Phonological analysis of conversational samples obtained from the same children at three-month intervals showed significant differences among children in rates of final consonant deletion, cluster reduction, vowelization, and…

Nine individual prosocial child behaviors of 2-year-olds were obtained from mothers and caretakers. These behaviors were combined into a fourfold scheme which was then used to assess child prosocial behavior outside a laboratory setting. In addition, the two dispositional attributes of sociability and happiness were assessed. Observations of 28…

Recent work suggests that the apparent shift from thematic to taxonomic concept organization reflects changes in children's preference for these forms of organization, rather than their capacity. A study was made to assess toddlers' knowledge of the different possible relations for the same concept and to extend the triad method to children under…

In order to examine the development of social pretend skills in the toddler period, social pretend play was observed in same and mixed age dyads. More complex social pretend play was expected in the mixed age than in the same age condition. A second purpose of the study was to compare 5-year-old children's attempts to communicate pretend meanings…

Temperament is examined from a longitudinal, within-individual perspective in order to investigate short-term change and patterns of temperament changes. For 100 consectutive days five mothers completed a temperament survey, reporting on their own and their two-year-old children's behavior. Patterns of change were identified for both mothers and…
