Interactional Synchrony and the Origins of Infant-Mother Attachment: A Replication Study 总被引:1,自引:0,他引:1
This study sought to replicate previous work in testing the hypothesis that interactions of dyads developing secure attachment relationships would be characterized by disproportionately synchronous and those of dyads developing insecure relationships by disproportionately asynchronous exchanges. Additionally, a priori hypotheses were tested regarding expected differences in the interactional histories of dyads developing insecure-avoidant and insecure-resistant attachments. Results supported the study's predictions in all cases. Dyads developing secure attachments were observed at 3 and 9 months to interact in a disproportionately well-timed, reciprocal, and mutually rewarding manner; dyads developing insecure relationships were disproportionately characterized by interactions in which mothers were minimally involved, unresponsive to infant signals, or intrusive. Within the insecure group, as predicted, 3- and 9-month interactions of avoidant dyads were characterized by maternal intrusiveness and overstimulation; resistant dyads were characterized at both ages by poorly coordinated interactions in which mothers were underinvolved and inconsistent. These findings are discussed as they lend to a growing body of evidence concerning associations between differential interactional histories and attachment quality. 相似文献

Conditions of Continuity and Discontinuity in Infant Negative Emotionality: Newborn to Five Months 总被引:1,自引:0,他引:1
This study investigated infant and caregiving-environment variables associated with continuity and discontinuity in infant negative emotionality between the newborn period and 5 months of age. Comparisons were made between groups of infants who evidenced similar levels of crying as neonates but differed by 5 months of age. For initially high-crying infants, mother personality traits, marital quality, and infant variables measured neonatally discriminated stable from changing infants. Ratings of mother sensitivity and infant responsiveness made at 5 months of age also related to continuity and discontinuity in negative emotionality over the first 5 months. 相似文献

The Determinants of Coparenting in Families with Toddler Boys: Spousal Differences and Daily Hassles 总被引:1,自引:0,他引:1
In order to advance understanding of the phenomenon of coparenting, naturalistic observations of firstborn sons were undertaken when they were 15 months of age at a time when both parents were home and family life was demanding. Narrative records of coparenting events were scored to determine the frequency with which parents supported and undermined each other and to test two hypotheses pertaining to individual differences in coparenting: that greater differences between spouses in demographic factors, personality, styles of relatedness and child-rearing attitudes would forecast more unsupportive and less supportive coparenting; and that the adverse effects of such spousal differences would be amplified by high levels of family stress, as indexed by frequency and intensity of daily hassles. Both hypotheses received support and are discussed in turn. 相似文献

The development of auditory temporal acuity during infancy was examined in 3-, 6-, and 12-month-old infants and in adults using the gap detection paradigm. Listeners detected a series of gaps, or silent intervals, or variable duration in a broadband noise. In order to vary the acoustic frequencies available to the listener, a high-pass noise was used to mask frequencies above specified cutoffs. High-pass maskers with cutoffs of 500, 2,000, and 8,000 Hz were used. The minimum detectable gap was determined using the Observer-based Psychoacoustic Procedure. The thresholds of 3- and 6-month-olds were considerably poorer than those of the adults, although the effect of masker condition was about the same for these 3 groups. The thresholds of 12-month-olds were significantly worse than the adults when the stimulus was unmasked or when the masker cutoff frequency was 2,000 or 8,000 Hz. When the masker cutoff frequency was 500 Hz, 12-month-olds fell into 2 groups: some had gap thresholds that were about the same as 3- and 6-month-olds, while some had gap thresholds that approached those of adults. In a second experiment, a larger group of 12-month-olds were tested with a 500-Hz masker cutoff. Average performance of 12-month-olds was about the same as that of 3- and 6-month-olds in Experiment 1. Some infants attained thresholds close to those of adults. Thus, gap detection thresholds are quite poor in infants, although the similarity of the effect of frequency on performance in infants and adults suggests that the mechanisms governing temporal resolution in infants operate qualitatively like those in adults. 相似文献

Jay Belsky 《Child abuse & neglect》1978,2(1):37-49
A review of the research on child abuse suggests three basic theoretical models to account for the etiology of abuse: (1) a psychiatric model emphasizing the role of the individual abuser; (2) a sociological model highlighting the role of social factors in abuse; and (3) the effect of the child on caregiver model pointing toward the role the child plays in stimulating his own maltreatment. After reviewing the research evidence in support of each model as well as documenting the inadequacies of each, it is concluded that only a comprehensive framework, subsuming each model, can expect to account for the occurrence of abuse. Furthermore, if treatment and prevention strategies hope to succeed in combatting this disturbing social problem, they must address the influential components highlighted by each of these three models. 相似文献

Designing, developing, and administering assessments has remained fairly unchanged across the past century. However, recent developments in instructional technology, learning science theory, and advances in the design of assessments necessitate a newfound perspective on assessment. The objective of the present article is to review the topic of assessment in depth—past, present, and future. Specifically, we focus on the use of technologically rich learning environments that have spurred advances in student assessment, new methods and procedures from these advances, and consequently the need to consider implementing comprehensive assessment systems that provide rigorous and ubiquitous measurement of the whole student learning experience. 相似文献

Although several studies have now examined the relations between mother-child and sibling interaction, the role of fathers in the development of sibling relationships is noticeably absent. The present study included assessments of both mother-child and father-child interaction in order to examine the correlates of sibling conflict and cooperation. Home observations of parent-child and sibling interaction and reports of differential parental treatment were obtained for 30 families with 2 preschool children when the firstborns were approximately 6 years old. Earlier assessments of infant-mother and infant-father attachments when firstborns were 12 and 13 months old, respectively, were also available, as were prior laboratory assessments of mothering and fathering when the oldest child was 3 years of age. Results suggested that sibling conflict and aggression were related to high levels of conflict between the mother and the 2 children at 6 years, intrusive and overcontrolling mothering at 3 years, and an insecure infant-mother attachment. Facilitative and affectionate fathering, on the other hand, was associated with prosocial sibling interaction. Early relationship experiences between parents and their firstborn children had an enduring effect on the quality of sibling relationships and interacted with differential parental treatment in predicting sibling relationship outcomes. 相似文献

Salt-hungry rats fail to develop anticipatory wheel-running activity when maintained under schedules of limited daily access to salt, in marked contrast to the robust anticipatory activity seen under food-access schedules. This suggests that the circadian oscillator underlying food-anticipatory activity is specifically related to food access and does not readily generalize to other scheduled resources. However, an alternative hypothesis is that rats are capable of anticipating daily salt-access periods, but that this anticipation is not manifest in wheel-running activity. In the present study, we maintained adrenalectomized rats under schedules of limited daily access to salt in which all salt was obtained by leverpressing. The results indicate that rats are capable of anticipating daily salt access by reference to an endogenous circadian timing mechanism. However, this behavior differs in several respects from that seen under food-access schedules. 相似文献
