Children's interactions with peers in early childhood have been consistently linked to their academic and social outcomes. Although both child and classroom characteristics have been implicated as contributors to children's success, there has been scant research linking child temperament, teacher–child relationship quality, and peer interactions in the same study. The purpose of this study is to examine children's early temperament, rated at preschool age, as a predictor of interactions with peers (i.e., aggression, relational aggression, victimization, and prosociality) in third grade while considering teacher–child relationship quality in kindergarten through second grades as a moderator and mediator of this association. The sample (N = 1364) was drawn from the NICHD Study of Early Child Care and Youth Development. Results from structural equation models indicated that teacher–child conflict in early elementary grades mediated links between children's temperament and later peer interactions. Findings underscore the importance of considering children's temperament traits and teacher–child relationship quality when examining the mechanisms of the development of peer interactions.  相似文献

Perceptual grouping is the process by which elements in the visual image are aggregated into larger and more complex structures, i.e., “objects.” This paper reports a study of the spatial factors and time-course of the development of objects over the course of the first few hundred milliseconds of visual processing. The methodology uses the now well-established idea of an “object benefit” for certain kinds of tasks (here, faster within-object than between-objects probe comparisons) to test what the visual system in fact treats as an object at each point during processing. The study tested line segment pairs in a wide variety of spatial configurations at a range of exposure times, in each case measuring the strength of perceptual grouping as reflected in the magnitude of the object benefit. Factors tested included nonaccidental properties such as collinearity, cotermination, and parallelism; contour relatability; Gestalt factors such as symmetry and skew symmetry, and several others, all tested at fine (25 msec) time-slices over the course of processing. The data provide detailed information about the comparative strength of these factors in inducing grouping at each point in processing. The result is a vivid picture of the chronology of object formation, as objects progressively coalesce, with fully bound visual objects completed by about 200 msec of processing.  相似文献

Shestov’s work can be summed up under six headings. Three are sharp contrasts, three are paradoxes. (1) First there is the contrast between Shestov the person, who was moderate, competent, and calm, and Shestov the thinker, who was extreme, incandescent, and impassioned. (2) Then there is the contrast between his critique of reason, his acceptance of irrationalism, and the means by which he attacks the former and defends the latter: namely, careful rational argument. Sometimes he argues like a lawyer (after all, he had a law degree from Moscow University). (3) Shestov speaks repeatedly of the “horrors and atrocities of human existence.” But his examples are always drawn from history or literature, never from his own life, although we know that he experienced much horror. (4) Nietzsche is the thinker whom he invokes most frequently, and most warmly. Yet, paradoxically, Shestov completely ignores most of Nietzsche’s central themes. (5) Shestov’s skeptical doubts are mostly directed at rationalism; he is not skeptical about the existence or benevolence of God. Yet he is explicitly skeptical about divine omniscience and implicitly skeptical about divine omnipotence in a metaphysical sense, though not in its ethical application. (6) Shestov has a deep faith that God can undo all the horrors of life, putting an end to all suffering. At the same time he knows that this will not, and cannot, happen, since the very idea of undoing the past, erasing its horrors, is conceptually incoherent.  相似文献

The present paper explores the drug use of a sample of inner‐city junior high school youths by examining a hypothesized, interactive relationship between the perceived toughness/drug use in their neighborhood and the youths’ demographic, neighborhood orientation/involvement, and drug use context factors in regard to their drug involvement. In support of our hypothesis, discriminant analysis indicated that different processes were reflected in the correlates of the youths’ involvement with drugs in the three settings. Implications of these findings for drug abuse treatment and prevention strategies are discussed.  相似文献

Previous research has shown that early and late bilinguals differ in their language learning experiences and linguistic outcomes. However, evidence of differences between these bilinguals on measures of executive function (EF) has been mixed. As a result, the current study sought to (1) determine whether early and late bilinguals vary from one another and (2) exhibit cognitive advantages in EF relative to monolinguals. One hundred and five participants (42 monolinguals, 40 early bilinguals and 23 late bilinguals) completed the study. Participants' EF skills were assessed using the Auditorily Cued Number Numeral Task. Overall, the results did not reveal clear advantages for the early bilinguals compared to the two other groups. In fact, early bilinguals and monolinguals were equivalent in their performance on the EF task, whereas the late bilinguals were less accurate, relative to the other two groups. The differences in the performance of early and late bilinguals are discussed in terms of the competition model of second-language learning proposed in previous research. Taken together, these findings indicate that individual differences in EF influence the observed differences found in EF across language groups.  相似文献

Research on early childhood predictors of violent behaviors in early adulthood is limited. The current study investigated whether individual, family, and community risk factors from 18 to 42 months of age were predictive of violent criminal arrests during late adolescence and early adulthood using a sample of 310 low-income male participants living in an urban community. In addition, differences in trajectories of overt conduct problems (CP), hyperactivity/attention problems (HAP), and co-occurring patterns of CP and HAP from age 1½ to 10 years were investigated in regard to their relationship to violent and nonviolent behaviors, depression, and anxiety at age 20. Results of multivariate analyses indicated that early childhood family income, home environment, emotion regulation, oppositional behavior, and minority status were all significant in distinguishing violent offending boys from those with no criminal records. In addition, trajectories of early childhood CP, but not attention deficit hyperactivity disorder, were significantly related to self-reports of violent behavior, depressive symptoms, and anxiety symptoms. Implications for the prevention of early childhood risk factors associated with adolescent and adult violent behavior for males are discussed.  相似文献

In this research, lexical and morpholexical reading in Italian children ages 8 to 10 years were investigated. Children and control adults were administered two tasks on words and pseudowords: visual lexical decision and naming. Word frequency effects in both lexical decision and naming were found in both children and adults. For all age groups pseudowords made up of roots and derivational suffixes were decided more frequently as possible words and were named more quickly and accurately than matched pseudowords with no morphological constituency. These results show that morpholexical reading is available and efficient in young readers of a shallow orthography, with similar patterns in children and adults.  相似文献

Discrimination has been shown to be related to diminished psychological adjustment and greater risk for substance use when personally experienced by adolescents and when their caregivers experience discrimination. Our research considers the impact of primary caregiver experiences of racial- and socioeconomic-based discrimination in early (age 3–5 years) and late childhood (age 9½) on adolescent disruptive behaviors (age 14) with a large sample of diverse caregiver–child dyads (N = 634). In addition, we examine the potential protective effects of parent–child relationship quality in early and late childhood in buffering the effects of caregiver discrimination on adolescent disruptive behaviors. We also explore possible gender differences in children's vulnerability to engage in disruptive behaviors in the context of caregiver experiences of discrimination. The findings from this study indicate that at trend level, early childhood experiences of primary caregiver discrimination (ages 3–5) predicted adolescent disruptive behaviors, accounting for the effects of more recent (age 9½) caregiver discrimination. In addition, parent–child relationship quality at age 9½ years was found to buffer the effects of late childhood (age 9½) primary caregiver discrimination on adolescent disruptive behaviors for both male and female youth. The findings highlight the need for prevention and intervention techniques that foster healthy and positive primary caregiver–child relationships.  相似文献

For simplicity, contemporary models of written-word recognition and reading have unspecified feature/letter levels—they predict that the visually similar substituted-letter nonword PEQPLE is as effective at activating the word PEOPLE as the visually dissimilar substituted-letter nonword PEYPLE. Previous empirical evidence on the effects of visual similarly across letters during written-word recognition is scarce and nonconclusive. To examine whether visual similarity across letters plays a role early in word processing, we conducted two masked priming lexical decision experiments (stimulus-onset asynchrony = 50 ms). The substituted-letter primes were visually very similar to the target letters (u/v in Experiment 1 and i/j in Experiment 2; e.g., nevtral–NEUTRAL). For comparison purposes, we included an identity prime condition (neutral–NEUTRAL) and a dissimilar-letter prime condition (neztral-NEUTRAL). Results showed that the similar-letter prime condition produced faster word identification times than the dissimilar-letter prime condition. We discuss how models of written-word recognition should be amended to capture visual similarity effects across letters.  相似文献

This study investigates differences in the language environments experienced by multilingual and monolingual infants in early childhood education and care (ECEC) settings. The Language Environment Analysis (LENA) technology was used to collect day-long audio-recordings from 181 one-year-old infants (age range from 12 to 21 months). We examined whether infants’ multilingual status predicts the amount of educators’ language input (adult word count, AWC), child vocalizations (CVC) and conversational turns (CTC), as well as interaction effects on AWC, CVC and CTC of infants’ multilingual status and other infant, home and ECEC characteristics. Multilevel mixed effects models revealed no main effect of infants’ multilingual status on the language environment outcome variables. Instead, infant gender significantly predicted adult word count, with female infants hearing more words from educators than male infants. There was a significant interaction effect between the infants’ multilingual status and both their age and length of time in an ECEC setting on child vocalizations. While monolingual infants produced more vocalizations as their age increased, multilingual infants did not show this increase in vocalizations with age. Further, the difference between monolingual and multilingual children’s vocalizations decreased as the length of time in ECEC increased. There were no significant predictors of conversational turns. Findings from this study suggest that early childhood educators do not adjust their talk according to the multilingual status of the infants. However, multilingual infants do not increase their vocalizations as their age increases to the same extent as do their monolingual peers. The interaction effect between multilingualism and the length of ECEC attendance also implies that ECEC environments may be particularly beneficial for supporting multilingual infants’ vocalizations. This study highlights the need to provide pedagogical support to educators to help them to encourage multilingual infants’ vocalizations in ECEC settings.  相似文献

In early major works, Cassirer and Schlick differently recast traditional doctrines of the concept and of the relation of concept to intuitive content along the lines of recent epistemological discussions within the exact sciences. In this, they attempted to refashion epistemology by incorporating as its basic principle the notion of functional coordination, the theoretical sciences' own methodological tool for dispensing with the imprecise and unreliable guide of intuitive evidence. Examining their respective reconstructions of the theory of knowledge provides an axis of comparison along which to locate Cassirer's Neo-Kantianism and Schlick's pre-positivist empiricism, and an immediate background of contrast to the subsequent rise of logical empiricism. For in the absence of intuition all our knowledge is without objects and therefore remains entirely empty. (Kant A62/B87) And how awkward is the human mind in diving the nature of things when forsaken by the analogy of what we see and touch directly? (Boltzmann 1895)  相似文献

Sequential analyses examined associations between the working alliance and therapist-adolescent communication patterns in 10 Spanish cases of brief conjoint family therapy. Early sessions with strong versus problematic alliances, rated by observers, were selected for coding of relational control communication patterns. No differences were found in the frequency of exchanges, but competitive responding by the therapists (reflecting an interpersonal struggle for control) was significantly more likely in problematic alliance sessions than in strong alliance sessions. Cases in which the adolescent's alliance with the therapist remained positive from Session 1 as compared with Session 3 showed a decrease in the likelihood of competitive symmetry. Notably, when the quality of the alliance deteriorated over time, the therapists were increasingly more likely to respond to the adolescents' domineering messages in a competitive manner. Results underscore the need to avoid competitive responding in order to ally with adolescents in conjoint family treatment.  相似文献

Different theories make different predictions about how mean levels of personality traits change in adulthood. The biological view of the Five-factor theory proposes the plaster hypothesis: All personality traits stop changing by age 30. In contrast, contextualist perspectives propose that changes should be more varied and should persist throughout adulthood. This study compared these perspectives in a large (N = 132,515) sample of adults aged 21-60 who completed a Big Five personality measure on the Internet. Conscientiousness and Agreeableness increased throughout early and middle adulthood at varying rates; Neuroticism declined among women but did not change among men. The variety in patterns of change suggests that the Big Five traits are complex phenomena subject to a variety of developmental influences.  相似文献

Using data from the NICHD SECCYD (N = 1053), we used two-level hierarchical linear models with site fixed effects to examine whether teacher-child closeness and conflict moderated associations between two indicators of early socioeconomic status (maternal education and family income) and standardized measures of children's math and reading achievement at 54 months, 1st, 3rd, and 5th grades. Children whose mothers had lower levels of education and conflictual relationships with teachers exhibited lower reading achievement, on average, across elementary school. At the same time, children with less educated mothers who experienced increases in teacher-child closeness and decreases in teacher-child conflict exhibited improvements in reading achievement across elementary school. Finally, low teacher-child closeness elevated the risk for poor math achievement posed by low family income. Implications for intervention design and development are discussed.  相似文献

Children's change over time in frequency of finger use on number combinations was examined in relation to their change in accuracy. Performance was tracked longitudinally over 11 time points, from the beginning of kindergarten (mean age = 5.7 years) to the end of second grade (n= 217). Accuracy in number combinations increased steadily during the time period while frequency of finger use declined. Correlations between finger use and accuracy decreased gradually, ranging from 0.60 in kindergarten to -0.15 at the end of second grade. Low-income children showed linear growth in frequency of finger use while middle-income children slowed down by second grade and even started to decline. Although girls and boys showed similar growth patterns in frequency and accuracy, boys used their fingers less often than girls and were more accurate. The findings indicate that finger use is most adaptive when children are first learning number combinations, but this benefit lessens over time.  相似文献
