This 5-year longitudinal study focuses on the development of intelligence and emotional maturity in 317 premature and 78 full-term Romanian infants. (CM)

Investigated three-month-olds' abilities to discriminate and recognize smiling and frowning expressions of mothers and strangers. Discrimination and recognition occurred regardless of the adult who was involved; however, more infants discriminated the mothers' expressions than the strangers', and boys looked at their mothers' faces longer than did…

Presents an experiential-educational approach to families with infants integrating dance and movement therapy with family therapy theories and techniques. Nonverbal techniques are the only possible methods of working directly with infants present with their parents in these workshops. The focus is on negotiations and exchanges of feelings in…

Infants were classified as high or low in differential vocal responsiveness (DVR), and tested for degree of response to stimulation by a stranger and to stimulation by their mothers. The infants' DVR classification was related to scores on the Stanford-Binet and the Illinois Test of Psycholinguistic Abilities. (Author/SS)

A twin analysis was applied to infants' social behavior in standardized situations that permitted the comparison of social responding to mother and a stranger in different contexts. Twenty-one identical twin pairs and twenty-five fraternal twin pairs were observed in their homes using time-sampled observations of specific behaviors. (Author/SS)

Examines two models of the compelling nature of the infant cry and its effectiveness in eliciting caregiving behavior. (MP)

Two groups of six 3-month-old infants participated in a study to investigate the effect of social stimulation on infants' vocalizations. (MS)

A total of eighty 9-month-old infants were presented with a problem consisting of several different conditions which separated response, position on a table, and absolute spatial position as factors leading to errors in search for hidden objects. (MS)

Used multilevel analyses to examined the amounts of time infants spent asleep, awake, content, feeding, fussing, and crying at 2, 6, 12, and 40 weeks of age. Found that day-to-day fluctuations accounted for between 44 and 53% of the variance in amounts of time sleeping, fussing, and crying. (MDM)

Describes various types of play typical of infants and toddlers. Includes discussion of the developmental benefits of object play, social play, motor play, and imitation. Focuses on the concept of causality, toddler-invented games, repeated movement to gain mastery, and the beginnings of dramatic play. (KB)

Discusses how Adolph's research is relevant to four themes that are foundational to contemporary research on the development of perception and action: (1) reciprocity between perception and action; (2) prospective control of behavior; (3) variation and selection in the development of new behaviors; and (4) contributions of age and experience.…

Discusses Adolph's research on locomotion with regard to the requirements of an ecological psychology, especially the use of control laws; her examination of individual styles and normative patterns as it reflects a dynamic systems perspective; and her use of cognitive processes of decision making in explaining why infants approach or avoid a…

Evaluates the reliability and validity of a parental involvement measure using a group of mothers and 15-month-old infants (N=137). Factor analysis revealed that the measure's four scales were internally consistent. Results indicate moderate to high test-retest reliability and substantial evidence of construct validity. (RJM)
