Examined predictive relations between infant assessments and behavior problems at age 7 in a low-income sample. Found that disorganized infant attachment behavior and below average mental development at 18 months were associated with externalizing behavior at 7 years. Avoidant infant attachment behavior was associated with later internalizing…

Studied relationship of temperament and same-sex peer interaction with gender differences in adjustment. Found that highly arousable boys who played with same-sex peers had increased problem behaviors. Arousable girls who played with other girls were relatively unlikely to show problem behaviors. The arousability and same-sex peer interaction…

Examined relation of 7-year olds' attachment representations to later behavior and academic competency during middle childhood and adolescence. Controlled for social class, gender, IQ, perspective-taking ability, and prior competency. Found that attachment representations did not predict disruptive behavior or extroversion, but secure…

Examined cognitive competencies and motivation in economically advantaged and disadvantaged preschoolers and kindergartners over a two-year period. Found that disadvantaged children had poorer cognitive scores than advantaged children. Cognitive gains were equal after one or two years in school, with socioeconomic status (SES) differences…

Infants were familiarized with plastic animals from one of two categories (land or sea) that were judged similar or variable by adults. Infants were then tested with novel animals from the same or a different category. Thirteen-month-olds in the similar familiarization condition dishabituated to novel animals of a different category and, to a…

Challenges conclusions about infants' cognitive processing from prior research in favor of the importance of perceptual processes and the effects of stimulus novelty and familiarization. Considers problems with the two-test habituation design of earlier studies and proposes a new methodology that eliminates those problems. Describes a study the…

Infants looked at visual displays of two or three items while listening to auditory sequences of two or three sounds. When the rate and duration of sounds were constant, infants looked longer at the visual display that was numerically equivalent to the auditory sequence. When the rate and duration of sounds varied, infants showed no preference for…

Examined the understanding of general correspondences between print and language and specific correspondences in alphabetic and nonalphabetic languages on the part of monolingual (English) and bilingual (French-English, Chinese-English) 4- and 5-year-olds. Bilingual children understood the general symbolic representation of print better than…

In three experiments, 3-, 4-, and 5-year olds and adults identified words from a list presented by a single talker or multiple talkers. Subjects were less accurate identifying or slower repeating words spoken by multiple speakers than by a single speaker. Processing of multiple speakers' words became easier with age. Children matched their…

Studied the gestures of blind, sighted, and blindfolded sighted 10- through 12-year olds as they engaged in narration, direction giving, or conservation tasks. Found that blind children produced gestures, though not in all contexts in which sighted children produced gestures; and that blind children's gestures resembled sighted children's gestures…

Children's phonological processing abilities, reading skills, and vocabulary were assessed annually from kindergarten through grade four. Found that individual differences in phonological awareness were related to subsequent differences in word-level reading, and that individual differences in letter-name knowledge were related to subsequent…

Maternal instructional behavior at home and maternal ratings of children's temperament when children were 18 months old predicted mothers' problem-solving behaviors and children's performance on a cognitive problem-solving task at 30 months. Mothers' cognitive assistance to children during tasks at 18 and 30 months predicted children's cognitive…

Children's attachment behavior was assessed at 18 months. Children's behavior with peers was observed and teachers' ratings of children's peer relations were gathered from 18 to 24 months. Found that, in response to their own positive behaviors, insecure-resistant children received fewer positive reactions from peers, and insecure-resistant and…

Parents sang a song once to their infants and once in a simulated setting. The song's pitch was higher and tempo slower for infant-directed than simulated singing. Listeners of varying child care experience, musical background, and culture were able to identify which version was infant-directed. Listeners who rated parents' emotional engagement…

Assessed coping with homesickness, perceived control over homesickness, and adjustment among 8- to 10-year-olds spending two weeks at a summer camp. Found that children's most frequent and effective method of coping was engaging in distracting physical activity; coping by adjusting oneself to conditions increased through adolescence; and the most…
