Data indicate that the interventions provided differed in their effectiveness in calming newborns to a highly significant degree. (Authors)

The Babkin reflex is a reaction to the simultaneous pressing of the palms of the hands of the infant. (Authors)

Examined consistency of hand preference in a longitudinal study of children between 18 and 42 months of age. Results showed a sex-specific relationship between hand consistence and intellectual development. Females with consistency of handedness were precocious compared to females without such consistency; the same relationship did not hold for…

Some of the findings of a longitudinal study of three infants between their 11th and 22nd months to document development of linguistic expression of the agent concept indicated that first vocalizations were inconsistently associated with nonverbal agentive behaviors and later mature utterances coded agent-action-recipient events.

Reviews the history of the developmental study of infants and children at biological risk and appraises the current state of the art. Four research phases during the period from 1920 to the present are identified, each reflecting aspects of the social, political, health, and psychological zeitgeist. (Author/RH)

Investigated the effect of increasing familiarization time on the visual recognition memory of 6- and 12-month-old full-term and preterm infants. Results suggested that persistent differences exist between preterm and full-term infants throughout at least the first year of life in this fundamental aspect of cognition. (Author/RH)

An Ames static trapezoidal window was used to test infants' responsiveness to pictorial depth. Sensitivity to the pictorial information for depth that is present in the trapezoidal window appears to develop after the age of 22 weeks. (Author/DB)

Preferential looking at stimuli varying in temporal frequency was examined in 11 prematurely born infants. The relationship between amount of looking and stimulus frequency yielded a significant linear trend with the fastest frequency used (4 hertz) being most preferred. (Author/DB)

Seeks to determine (1) whether 11- and 13-month-old infants directed their eye fixations to the referent of an object word said by the mother, and (2) whether there was a developmental shift in responding to object words at these two ages. Controls were set for response bias, stimulus preference, and maternal cuing. (Author/RH)

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)
