Full-term infants who had slept in the prone position since birth were followed to detect early postural abnormalities and differentiate potential peripheral abnormality from abnormalities of a central origin. Results showed that disappearance of initial signs of abnormality appeared to be muscular, and symptoms disappeared faster when a motor…

Explores influence of culturally related caretaking practices on motor development among four Bambara infants who were observed for two days with paper-and-pencil event-recording technique and video films. Records were made of spatial positions experienced in daily behavior and postural adjustments required by maternal manipulations during…

Eighty at-risk infants were administered the Mental and Motor Scales of the Bayley Scales of Infant Development at 6 and 12 months of age. Test-retest reliability scores of .71 on the Mental Scale and .69 on the Motor Scale were obtained. (Author/JDD)

Measures the degree of interdependence in timing between infants' right and left arm movements and between movements of both arms and the onsets of stressed vowels in tape-recorded infant-appropriate speech. (HOD)

Examines 24 mother/impaired infant dyads to study the quality of interaction using the Ainsworth-Wittig attachment paradigm. Measures of general development and degree of child impairment significantly differentiated "classifiability" of attachment in the Ainsworth scheme. Infants rated higher on a social responsiveness measure were more…

Recent work on the development of the perceptual information-seeking function of the hand in relation to its motor-executive function is reviewed. (PCB)

Tested infants in their second year with a box task to determine whether they would show a hand preference in solutions involving complete differentiation of roles for the two hands. (HOD)

Reports an 18-month longitudinal study of sign language acquisition in very young children of deaf parents. Results indicate that some revision of views on cognitive prerequisites for language is necessary. Implications for nonspeaking populations and for developmental theory are discussed. Reviews briefly sign language training programs for…

From earliest infancy, a typically developing child imitates or mirrors the facial expressions, postures and gestures, and emotional behavior of others. Where does this capacity come from, and what function does it serve? What happens when imitation is impaired? Synthesizing cutting-edge research emerging from a range of disciplines, this…

Explores the relation between the infant's ability to negotiate the environment and the quality of the infant-mother attachment relationship. (HOD)

A quantifiable regimen of supplemental rotary vestibular stimulation was administered in a cross-over longitudinal design to 11 nonhandicapped and 10 Down's syndrome infants. Results indicated that supplementary rotary vestibular stimulation produced no measurable gain in motor ability. Greater gains were exhibited in the early phase of the study,…

Evaluation of the Kent Scoring Adaptation, which determines developmental ages in several domains based on an infant's performance on the Bayley Scales of Infant Development, with 27 at-risk infants supported the concurrent validity of the cognitive, language, and, to a degree, social domains of the Kent procedure but not the fine and gross motor…

Reports on a longitudinal study of cognitive and motor development among infants born to adolescent and adult mothers when race, parity, socioeconomic status and prenatal care were controlled and home environment evaluated. (HOD)

An intensive early intervention program was evaluated by assessing gains made by 44 special needs children (age 2) in cognition, gross motor, fine motor, receptive language, and expressive language domains. Comparison of actual to predicted posttest scores did not reveal significant gains in any domains. In cognition, gross motor, and fine motor…
