Three groups of 12-month-old infants were tested for cross-modal and intramodal transfer of information about shape. Infants were given either visual or tactual familiarization and then tested for visual or tactual recognition. Overall, intramodal transfer was superior to cross-modal transfer. Cross-modal asymmetries were found for which possible…

Examines individual variation in infants' exploratory play with objects. Distinguishes exploratory and nonexploratory manipulative play, and shows that only exploratory play relates to focused attention and learning. Discusses resistance to distraction during focused attention, relationships between exploratory play and mastery motivation, and the…

Three experiments found that (1) nine-month olds listened more to two-syllable words with strong-weak stress patterns than weak-strong stress patterns; (2) six-month olds showed no preferences for stress patterns; and (3) nine-month olds showed preferences for strong-weak over weak-strong stress patterns in speech sounds passed through a low-pass…

Examined instrumental learning in premature infants by providing 45 infants at 33 weeks conceptual age with either a teddy bear that "breathed" quietly at the infant's respiration rate (BB) or a nonbreathing bear (NBB). Over a two-week period, infants provided with the BB decreased their latency to contact the bear; infants exposed to the NBB…

Thirty infants were studied monthly between one and four months to determine how long cyclical motor activity (CM) persists beyond neonatal period. Although rate and irregularity of CM during active sleep and waking states did not change across these four months, there was a pronounced drop in the strength of CM in the waking state from two months…

Weekly observations of 4 infants in a standard arm-extended reaching task demonstrated that the infants first reached at ages ranging from 12 to 22 weeks. Results suggest that the infant central nervous system does not contain programs that detail hand trajectory or muscle activation patterns; rather, these patterns are the consequence of the…

Measures of positive and negative affect and affect ability; of look, approach, and proximity behavior; and of overall response pattern were obtained from 66 infants of 12 months. These measures and other results suggested that both parents are significant sources of emotional guidance for infants in conditions of uncertainty. (RH)

A parent recounts the process of grieving following the birth of her brain damaged son including denial and anger, guilt, depression, and the elusiveness of complete acceptance. (DB)

Examined data from National Longitudinal Survey of Youth to investigate relationship between infant affect and quality of home environment. Found that infant irritability was negatively correlated with quality of home environment in both low-risk and high-risk families. Infant positive affect was more strongly related to quality of care in…

This study compared role of motion in adults' and infants' perception of object unity. Findings favored ecologically-oriented accounts of object perception. Motion was a determinant of object unity for infants. Alignment and common motion contributed to adults' object-unity perception; synchronous color changes did not. Infants detected…

Examined whether 6.5- and 5.5-month-old infants believe, like 11-month-old infants, that a moving object's size affects how far a stationary object is displaced in a collision. After a habituation event, tests indicated that the 6.5-month-old infants and 5.5-month-old female infants believed the size of the moving object affected the collision…

This retrospective study compared videotape footage at 8-10 months of 15 children later known to have autism spectrum disorder and videotapes of 15 same-age children with typical development. The strongest finding was that infants with early onset autism were much less likely to orient when their name was called than typically developing infants.…

Examined continuity in attachment classification from infancy through adolescence and related it to autobiographical memories of childhood, divorce, and maladjustment in white middle-class children. Found no continuity in attachment classification from 1 to 18 years and no relation between infant attachment status and adolescent adjustment.…

Data from the Collaborative Perinatal Project analyzed for a subsample of 100 Asian Americans showed a higher IQ for the Asian American sample at age 7, and larger cranial capacity at birth, 4 months, 1 year, and 7 years as compared to Whites and Blacks. Socioeconomic status related to cranial capacity and IQ scores, but not stature or weight.…

Examines the relationship between hypnosis and human development. Defines hypnosis within a communications framework, and identifies essential features of hypnosis in the communicative exchanges of the first months of life; this forces a reconsideration of the understanding of the ontogenesis of hypnosis. Identifies four key features of hypnosis,…
