Based on a family systems perspective, this research examined the role of parental gender and family play context in parent–toddler interactions and how behaviours of family members influence each other. Sixty‐seven mostly White, middle‐class families consisting of a mother, father and toddler were videotaped in three separate sessions: mother–child, father–child and both parents–child at a university laboratory setting. The results indicated that there were significant main effects of both parent gender (mother versus father) and context (dyadic versus triadic) on parents' positive and negative parenting and children's engagement and negativity toward parents. Higher levels of mutual engagement between mothers and toddlers were associated with lower levels of fathers' positive parenting and children's engagement with fathers, when moving from the dyadic to the triadic play context. However, fathers' mutual engagement with toddlers was not associated with mothers' parenting quality and child interactive behaviours with mothers. There were also interaction effects of parent gender and context on parents' negative parenting and children's engagement and negativity toward parents. This study adds unique insights to the differences and similarities of parent–child dyadic and triadic interactions during toddlerhood. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

The objective of this study was to examine (a) anxiety and depression symptoms in children with Asperger syndrome (AS) compared to children with attention-deficit/hyperactivity disorder (ADHD) and children with depressive disorder; (b) parental anxiety and depressive symptoms in the three groups; and (c) the association between the anxiety and depression symptoms of children and their parents. The emotional and behavioral problems of 56 children with AS (48 boys, 8 girls, mean age, 9.39 ± 2.01 years) were compared with 56 ADHD children and 56 depressive disorder children, matched for age and sex. Their parents’ anxiety and depression symptoms were also compared. Trait-anxiety and internalizing problems in AS children were higher than those in ADHD children and as high as those in depressive disorder children (F = 8.83, p < 0.001 and F = 8.21, p < 0.001). Parents’ anxiety and depression symptoms did not differ among the three groups, but correlations between maternal anxiety and depression and children’s emotional and behavioral problems were most prominent in the AS group. We suggest that the assessment and treatment of children with AS should involve detailed assessment, possible concomitant treatment for comorbid anxiety and depression, and parental education about the effect of parental emotional states on children. 相似文献

Two self-paced reading experiments using a paraphrase decision task paradigm were performed to investigate how sentence complexity contributed to the relative clause (RC) attachment preferences of speakers of different working memory capacities (WMCs). Experiment 1 (English) showed working memory effects on relative clause processing in both offline RC attachment preferences and in online reading time measures, but no effects of syntactic complexity. In Experiment 2 (Korean), syntactic complexity due to greater distance between integrating heads, as measured by the dependency locality theory (Gibson in Cognition 68:1–76, 1998), significantly increased the proportion of attachment to NP1. However, no effects of working memory were found. The difference in results between English and Korean is proposed to be due to head-directionality effects. The results of our study support the conclusion that working memory-based accounts provide a better explanation than previous language-dependent accounts for differences in RC attachment preferences. We propose that previous language dependent-accounts of cross-linguistic differences in RC processing have overlooked the interaction between individual WMC and a language’s general structure, which is a central factor in RC attachment. 相似文献

Objective. Describe changes in mothers’ and fathers’ grief from 1 to 13 months after infant or child neonatal or pediatric intensive care unit death and identify factors related to their grief.
Methods. Mothers (n = 130) and fathers (n = 52) of 140 children (newborn–18 years) completed the Hogan Grief Reaction Checklist at 1, 3, 6, and 13 months postdeath.
Results. Grief decreased from 3 to 13 months for mothers and from 3 to 6 months for fathers. Grief was more intense for mothers of deceased adolescents and mothers whose children were declared brain dead.
Conclusion. Mothers’ and fathers’ grief intensity may not coincide, resulting in different needs during the 13 months after infant or child death. 相似文献

A satisfactory device for measuring activity of rats or other small animals has been a difficult problem. Several types of instruments have given incorrect measurements or are prohibitively expensive. Photocells give the same readout to a bobbing head as for a walk over a considerable distance requiring only the interruption of a light beam. Other devices require rotation of wheels or complex integrating circuits which must be replicated or scanned and recorded for simultaneous activity measurement of many animals. The device reported here utilizes the tilting of balanced cages to actuate a single microswitch coupled to an impulse counter for each cage. The system has functioned well for several years. 相似文献

Previous behavioral studies on a nervous strain of pointer dogs have demonstrated genetic as well as environmental components in the nervous trait. Behaviorally these animals are extremely hypervigilant, with an apparent low threshold to fear and show strong avoidance of humans. In addition, the nervous E strain dogs show an unusually high degree of sensitivity to the mange mite. These observations led to the initiation of studies to determine whether differences exist between the normal A strain and the E strain of dogs at the biochemical level. Although a number of biochemical parameters examined have shown no statistically significant difference between the two strains, the modification of serum creatine phosphokinase (CPK) activity in response to various types of stress does differ as a function of strain—the nervous dogs being less, not more, responsive than the healthy dogs. When not specifically subjected to stress the serum CPK levels in both strains were highly related to age. Significant differences between strains also have been demonstrated in the cerebrospinal fluid acetyl cholinesterase activity levels in older animals. Tryptophan loading experiments, conducted in the presence and absence of the monoamine oxidase inhibitor, tranylcypromine, resulted in no readily observable behavioral modification of either strain and the response of the cerebrospinal fluid 5-hydroxyindoleacetic acid levels was similar for the two strains. 相似文献

Several recent studies have shown that there is a general and marked canine cardiac response to humans and to petting from humans. Additional investigations have suggested that one of the major determinants of such responding is genetic. Some studies have indicated that such a response does not occur in nervous, short-haired pointer dogs. Evidence presented in this study indicates that a heart rate response to person and petting does occur in both the nervous as well as the normal pointer dog, but only when the animal is unrestrained. When placed in a restraining harness, only normal dogs showed a heart rate response to person and the characteristic bradycardia upon petting. Moreover, in this and two other separate experiments in which tones (CS’s) were given, it was observed in both normal and nervous strains that mean baseline heart rates were as much as 40 beats per minute lower in the restrained situation than in the unrestrained situation. These experiments measured retention of cardiac response to aversive conditional signals, since most dogs (9 of 12) had received both tones and shock in a bar jumping-shock avoidance experiment one year previously. However, heart rates varied inconsistently in both magnitude and direction of change upon CS showing little or no retention. These findings clarify ambiguity in previous reports and again show that the restraining conditions in an experiment can constitute a serious stress for the animal and be a major factor in the results. 相似文献

Older adults perform much like younger adults on language. This similar level of performance, however, may come about through different underlying brain processes. In the present study, we evaluated age-related differences in the brain areas outside the typical language areas among adults using a category decision task. Our results showed that similar activation patterns were found in classical language processing areas across the three age groups although regional lateralization indices in Broca’s and Wernicke’s areas decreased with age. The greatest differences, however, among the three groups were found primarily in the brain areas not associated with core language functioning including the hippocampus, middle frontal gyrus, ventromedial frontal cortex, medial superior parietal cortex and posterior cingulate cortex. Therefore, the non-classical language areas may exhibit an age-related difference between three age groups while the subjects show a similar activation pattern in the core, primary language processing during a semantic decision task. 相似文献

ABSTRACTVirtual simulations allow users to feel and manipulate objects as they would in the physical world. Guided by exemplification theory and risk communication research, a virtual exemplar was developed to allow users to feel the weight of the caloric density of unhealthy snacks (e.g., potato chips) to heighten risk perceptions on snack choices. A 3 (base-rate statistics, print exemplar, virtual exemplar) × 3 (Time 1, Time 2, Time 3) mixed design experiment (N = 152) compared the effect of three mediated modes of delivering health information at baseline, immediately after, and 1 week after treatments. Virtual exemplars led to greater spatial presence, issue involvement, and recommended health behavior than did base-rate statistics or print exemplars, but had no effect on perceived vividness. Heightened perceived susceptibility following virtual exemplars persisted for 1 week. Findings emphasized the importance of spatial presence elicited by an exemplar in heightening the perceived susceptibility of health risks both immediately after and 1 week after exposure. The role of spatial presence and vividness in the context of virtual exemplars that afford the illusion of firsthand experiences is discussed and compared against traditional exemplification research that has focused on the impact of secondhand experiences. 相似文献

In a pre‐test–post‐test cluster randomized trial, one of the methods commonly used to detect an intervention effect involves controlling pre‐test scores and other related covariates while estimating an intervention effect at post‐test. In many applications in education, the total post‐test and pre‐test scores, ignoring measurement error, are used as response variable and covariate, respectively, to estimate the intervention effect. However, these test scores are frequently subject to measurement error, and statistical inferences based on the model ignoring measurement error can yield a biased estimate of the intervention effect. When multiple domains exist in test data, it is sometimes more informative to detect the intervention effect for each domain than for the entire test. This paper presents applications of the multilevel multidimensional item response model with measurement error adjustments in a response variable and a covariate to estimate the intervention effect for each domain. 相似文献
