Some of the things that adults learn about language, and about the world, are very specific, whereas others are more abstract or rulelike. This article reviews evidence showing that infants, too, can very rapidly acquire both specific and abstract information, and considers the mechanisms that infants might use in doing so. 相似文献

This investigation documents the pattern of motor development of Brazilian infants over the first 6 months and compares the findings with a US norm. Infants were assessed once each month for the 6‐month period using the Bayley II Motor Scale, which represented the US norm for comparison. Participants monthly scores increased with age and were similar to the US profile. However, the Brazilian infants did exhibit mean scores significantly lower than their counterparts on tasks of sitting and grasping in the 3rd, 4th, and 5th month; at the 6th month, scores were comparable. Explanations for differences focus on possible cross‐cultural and maturational influences. Copyright © 2000 John Wiley & Sons, Ltd. 相似文献

Maternal reports about infant sleep care and ideas about the causes of awakening were obtained from telephone interviews with 104 middle class primiparae when their infants were 1 month and 1 year old. These reports were compared with their expectations about infant sleep before the birth of their child. It was found that most of the mothers were willing to ‘help’ their infants fall asleep, with 19 different kinds of techniques being spontaneously mentioned. Most of the techniques involved physical contact. The changes in technique from before birth to the end of the first year of life mainly concerned a decrease in the use of techniques involving holding the infant in the arms. From 1 month to 1 year, there was a decrease in rocking techniques, while at 1 year the use of a (bottle) feeding technique and taking the child into the parents' bed became apparent. The reasons mothers gave for infant awakenings varied from 1 month to 1 year. At 1 year, the most frequent reason was that the infant has ‘sufficient sleep’. Mothers' representations before the infant birth did not overlap with representations and reports of sleep handling after birth. Mothers were willing to apply and use a great variety of caring techniques that they perceived to be adjusted to the individual needs of their child. © 1998 John Wiley & Sons, Ltd. 相似文献

Imitation of tongue protrusions and mouth openings was investigated in 18 newborn infants using a procedure differing in three ways from previous laboratory studies: the mother presented the target gestures, she was permitted to adjust to the infant's reactions, and the infant's baseline response rate was assessed during face-to-face interaction. This procedure was assumed to facilitate infant imitation. Compared with baseline responses in face-to-face interaction, both tongue protrusions and mouth openings were imitated in the two conditions. No imitation, however, was found when the responses in the two imitation conditions were compared. These results are less convincing than those found in strictly controlled laboratory experiments. A less restrictive procedure did not, therefore, promote imitation. The mixed results could be explained by too short an exposure to the target gesture. If repeated and insistent gesturing is a crucial condition, neonatal imitation might be understood to be the result of instruction and teaching, rather than a means of mutual communication. © 1998 John Wiley & Sons, Ltd. 相似文献

Two experiments compared 6‐month‐old infants as they reach for an object. All were proficient reachers but with different levels of sitting ability. The object was presented at various distances, within and beyond reach of the infant. In the first experiment, the scaling of perceived reachability in infants with different postural abilities (i.e. non‐sitter, near‐sitter, and sitter infants) was explored. The second experiment investigated the role of proprioception in the scaling of perceived reachability by non‐sitter and sitter infants. In general, results suggest that perceived reachability is calibrated in relation to the degree of postural control achieved by the infant. Infants demonstrate a sense of their own situation in the environment as well as a sense of their own body effectivities. Both determine the execution, or non‐execution, of reaching for a distal object by young infants. Copyright © 1999 John Wiley & Sons, Ltd. 相似文献

Twenty preterm infants (birthweight<1500 g) and 20 healthy fullterm infants were compared with respect to emotional interaction with their mothers in a face‐to‐face situation at 3 months of age and in a feeding situation at 6 months of age (ages corrected for preterm birth). The assessed outcome was analysed with respect to infant variables (group, gender, gestational age, birthweight and neonatal risk factors) and maternal variables (age, education and parity). The outcomes at 3 and 6 months of age were also compared with findings of Griffiths’ testing at 10 months of age. At 3 months of age, the findings reveal no significant difference between the two groups with respect to emotional interaction. Maternal variables are more important for this interaction than are infant variables. The mother's level of formal education has a significant impact in both groups. In the group of fullterm infants, significantly lower scores for interaction are obtained by first‐time mothers in comparison with multi‐parae mothers. At 6 months of age, the difference between fullterm and preterm infants is significant. The preterm infants and their mothers now relate to one another more poorly than is the case for the fullterm dyads. These findings suggest that the difficulties encountered by the preterm infant emerge with time. Emotional interaction at this age and the results of Griffiths’ testing 4 months later are significantly correlated. Copyright © 1999 John Wiley & Sons, Ltd. 相似文献

This study examined the effects of in utero exposure to maternal depression and Superstorm Sandy, a hurricane that hit metropolitan New York in 2012, on infant temperament at 6 months. Temperament was assessed using the Infant Behavior Questionnaire-Revised. Maternal depression was measured by the Edinburgh Postnatal Depression Scale. The main effects and the interaction of maternal depression and Sandy exposure on infant temperament were examined using a multivariable generalized linear model. Results show that prenatal maternal depression was associated with lower emotion regulation and greater distress. Stratification and interaction analyses suggested that the adverse effects of prenatal maternal depression on problematic temperament were amplified by in utero Sandy exposure. This study underscores the importance of providing prenatal screening and treatment for maternal depression during pregnancy while also identifying high-risk families who may have suffered from disaster-related traumas to provide necessary services. As the frequency of natural disasters may increase due to climate change, it is important to understand the consequences of in utero stress on child development and to formulate plans for early identification. 相似文献

Siblings of children with autism spectrum disorders (ASD) present greater susceptibility to developmental problems, in comparison with siblings of typically developing children. The greater prevalence of mental health disorders among parents of children with ASD increases younger siblings’ vulnerability to emotional problems. The aim of this study is to compare the interaction between carers and babies aged 2 to 26 months (M = 11.7, SD = 6.9) who are siblings of children with ASD (ASD dyads) with the interaction of dyads of siblings of typically developing children (TD dyads). The protocol of Clinical Indicators of Risk for Child Development and the Coding Interactive Behaviour measures were used to evaluate interaction. ASD dyads presented higher scores of constriction in their interaction, P = .024, with babies presenting higher scores of withdrawal behavior, P = .003, and carers presenting higher scores of depressive mood, P = .008, when compared to TD dyads. The ASD dyads have interactive impairments more frequently than do the TD dyads. 相似文献
