Executive function (EF) skills are integral components of young children’s growing competence, but little is known about the role of early family context and experiences in their development. We examined how demographic and familial risks during infancy predicted EF competence at 36 months of age in a large, predominantly low-income sample of nonurban families from Pennsylvania and North Carolina in the United States. Using latent class analysis, six ecological risk profiles best captured the diverse experiences of these families. Profiles with various combinations of family structure, income, and psychosocial risks were differentially related to EF. Much of the influence of early risks on later EF appears to be transmitted through quality of parent-child interactions during infancy. Findings suggest that early family environments may prove to be especially fruitful contexts for the promotion of EF development.  相似文献

For decades, the literature on the emergence of triadic interactions considers the end of the first year of life as the time when children become able to communicate with others intentionally about a referent. Prior to that, children only relate in dyads, either with someone else or with an object. However, several researchers claim that referents are not naturally given in human communication and that they need to be established in interaction with others.In this study, we focus on earlier triadic interactions initiated by adults, when young babies still require an adult to bring the material world within their reach. In these early triadic interactions, ostensive gestures (with the object in the hand) are one of the first means of enabling the establishment of shared reference. Such gestures are easier to understand since sign (gesture) and referent (object) coincide. We conducted a longitudinal study with 6 babies filmed at 2, 3 and 4 months old in interaction with their mothers and a sounding object (a maraca). We analyzed different communicative initiatives by the adult and the child’s responses.The results show that children come to understand the adult’s communicative intention gradually through interaction. Adults include children in organized communicative “niches” based on ostensive actions, both through ostensive gestures and demonstrations of the use of the object. Consequently, the first shared understandings between adult and child take place around the object and its uses. Rhythm is a powerful tool used to structure the interaction. Eventually, adults provide space to children to actively interact with the sounding object themselves. These results highlight the importance of considering ostensive actions as a communicative tool that favors joint attention and action. They also bring some light to the interdependence between a child who actively perceives and acts, and the structured situation that the adult organizes for them.  相似文献

This research examined the benefits of interpreting physiological arousal as a challenge response on practice and actual Graduate Record Examination (GRE) scores. Participants who were preparing to take the GRE reported to the laboratory for a practice GRE study. Participants assigned to a reappraisal condition were told arousal improves performance, whereas control participants were not given this information. We collected saliva samples at baseline and after the appraisal manipulation, which were then assayed for salivary alpha amylase (sAA), a measure of sympathetic nervous system activation. Reappraisal participants exhibited a significant increase in sAA and outperformed controls on the GRE-math section. One to three months later, participants returned to the lab and provided their score reports from their actual GRE. Again, reappraisal participants scored higher than controls on the GRE-math section. These findings illuminate the powerful influence appraisal has on physiology and performance both in and out of the laboratory.  相似文献

This study examined whether teacher–child interactions characterized by teacher involvement, structure, and autonomy support at the beginning of second grade predicted children's global, academic, social, and behavioural self‐concept at the end of second grade. The study was conducted in 30 second grade classrooms with 570 children and their teachers. Data included teacher reports of teacher–child interactions and child reports of self‐concept. Results showed that, when controlling for the initial level of self‐concept, children's social self‐concept was predicted by teacher involvement, structure, and autonomy support. In addition, teacher autonomy support predicted high academic self‐concept. Finally, these teacher–child interaction characteristics did not contribute to the behavioural and global self‐concept. The results were similar for boys and girls. Copyright © 2010 John Wiley & Sons, Ltd.  相似文献

The Lausanne Trilogue Play (LTP) is a widely used laboratory situation designed for the systematic observation of mother-father-infant interactions for clinical and research purposes. Nevertheless, its ecological validity has never been tested. In this exploratory study, 49 primiparous parents with their 3-month-old infants were assessed by questionnaires to determine the extent to which their behaviour in the LTP was typical, that is, representative of everyday interactions. Results show that (a) most of the parents assessed their behaviour as typical and (b) the quality of triadic interactions was linked with parents’ assessment of the typicality of the infant’s behaviour.  相似文献

ABSTRACT

Many parents have experienced incidents in which their preschool child spontaneously (i.e., without prompting of any kind) recall a previously experienced event. Until recently, such spontaneous memories had only been examined in non-controlled settings (e.g., diary studies). Using a novel experimental paradigm, a previous study has shown that when young children are brought back to a highly distinct setting (same room, same experimenter, same furnishing), in which they previously experienced an interesting event (a Teddy or a Game event), spontaneous memories can be triggered. However, exactly which cues (or combination of cues) are effective for the children’s memory, remains unknown. Here, we used this novel paradigm to examine the possible impact of contextual cues at the time of retrieval. We manipulated whether the 35-month-old children returned to the same room (n?=?40) or to a different, but similarly furnished, room (n?=?40) after one week. The results revealed that although the children returning to a new room produced fewer spontaneous memories than the children returning to the same room, the difference was not significant. Interestingly, despite changing rooms, the children still produced spontaneous memories. Taken together the results may shed new light on the mechanisms underlying childhood amnesia.  相似文献

This study explored the temporal contingencies between infant and adult vocalizations as a function of the type of infant vocalization, whether adult caregivers’ vocalizations were infant-directed or other-directed, and the timescale of analysis. We analyzed excerpts taken from day-long home audio recordings that were collected from nineteen 12- to 13-month-old American infants and their caregivers using the LENA system. Three 5-minute sections having high child vocalization rates were identified within each recording and coded by trained researchers. Infant and adult vocalizations were sequenced and defined as contingent if they occurred within 1 s, 2 s, or 5 s of each other. When using 1 s or 2 s definitions of temporal adjacency, infant vocalizations generally predicted subsequent infant-directed adult vocalizations. A reflexive vocalization (i.e. a cry or a laugh) was the strongest predictor. Likewise, within 1–2 s timeframes, infant-directed adult speech generally predicted infant vocalizations with reflexive vocalizations being particularly predictive. Infant vocalizations predicted fewer subsequent other-directed adult vocalizations and were less likely following other-directed adult vocalizations when considering up to 5 s lags. This suggests an understudied communicative role for infants of non-infant-directed adult speech. These results demonstrate the importance of timescale in studying infant-adult interactions, support the communicative significance of reflexive infant vocalizations and other-directed adult speech in addition to more commonly studied vocalization types, and highlight the challenges of determining direction(s) of influence when using only two-event sequences.  相似文献

Parent-infant interactions are one of the most critical and enduring aspects of infants’ experience. Qualities of parent-infant interactions are related to social-emotional and cognitive developmental outcomes, yet how parent-infant interactions shape the functional organization of the brain is only beginning to be understood. Functional connectivity provides information about how brain regions communicate. Patterns of functional connectivity, thus far understudied in infants, have emerged as markers of abnormalities in the organization of the brain in at-risk infants as well as individuals with neurodevelopmetnal and neurodegenerative disorders. The current study sought to inform our understanding of relations between qualities of parent-infant interactions and functional connectivity. We report relations between responsiveness, reciprocity, and emotional tone and functional connectivity in theta, alpha, beta, and gamma in infants ranging from 6 to 11 month of age (N = 51). Results showed frontal-posterior connectivity in theta was inversely related to all three dimensions of parent-infant interactions. Gamma and alpha connectivity were positively associated with responsiveness and emotional tone, respectively. Results are discussed in the context of the experience-dependent nature of brain development, emphasizing how parent-infant interactions might be leveraged to structure early organization of the brain to foster healthy social-emotional and cognitive developmental outcomes.  相似文献

Judgments about actual and hypothetical events were examined. The study, conducted in elementary (first, third, and fifth grades) and junior high (seventh grades) schools, included behavioral observations and assessments of judgments. Observations were conducted of 108 events classified as moral, as conventional, and as mixed type. Participants’ reactions and communications differed by domain of the event. Judgments and justifications of 312 participants in the events showed that they discriminated between the domains on several dimensions. Judgments and justifications corresponded with ones made about comparable hypothetical situations. The study supported the proposition that judgments in the domains of morality and social convention about actual events correspond with judgments about hypothetical situations. It was also found that the domains are associated with the ways children interact socially.  相似文献
