The goals of the current study were to investigate the stability of temperamental exuberance across infancy and toddlerhood and to examine the associations between exuberance and social-emotional outcomes in early childhood. The sample consisted of 291 4-month-olds followed at 9, 24, and 36 months and again at 5 years of age. Behavioral measures of exuberance were collected at 9, 24, and 36 months. At 36 months, frontal electroencephalogram (EEG) asymmetry was assessed. At 5 years, maternal reports of temperament and behavior problems were collected, as were observational measures of social behavior during an interaction with an unfamiliar peer in the laboratory. Latent profile analysis revealed a high, stable exuberance profile that was associated with greater ratings of 5-year externalizing behavior and surgency, as well as observed disruptive behavior and social competence with unfamiliar peers. These associations were particularly true for children who displayed left frontal EEG asymmetry. Multiple factors supported an approach bias for exuberant temperament but did not differentiate between adaptive and maladaptive social-emotional outcomes at 5 years of age.  相似文献

In this longitudinal study, a quantitative and qualitative examination of the associations among parent-child relations, adult attachment styles, and relationship quality and theme in romantic narratives was conducted. Parenting and adult attachment style were assessed through questionnaires, whereas overall quality of romantic relationships (regard and importance), intimacy, and romantic story theme were examined with a life story approach (McAdams, 1993). At ages 17 and 26 years, 100 participants completed a series of questionnaires and also, at age 26, told a story about a "relationship-defining moment" with a romantic partner. Parent-child relations when participants were 17 years old were related predictably to all three attachment styles. About 70% of the sample told romantic stories with a "true love" type of theme. Associations between parent-child relations when the child was 17 and this type of theme in the story told when the participant was 26 were mediated by a more secure (and a less avoidant) attachment style when the participant was 26, as predicted. The implications of these findings for links between attachment models and the life story are discussed.  相似文献

Although incivility has been identified as an important issue in workplaces, little research has focused on reducing incivility and improving employee outcomes. Health care workers (N = 1,173, Time 1; N = 907, Time 2) working in 41 units completed a survey of social relationships, burnout, turnover intention, attitudes, and management trust before and after a 6-month intervention, CREW (Civility, Respect, and Engagement at Work). Most measures significantly improved for the 8 intervention units, and these improvements were significantly greater than changes in the 33 contrast units. Specifically, significant interactions indicating greater improvements in the intervention groups than in the contrast groups were found for coworker civility, supervisor incivility, respect, cynicism, job satisfaction, management trust, and absences. Improvements in civility mediated improvements in attitudes. The results suggest that this employee-based civility intervention can improve collegiality and enhance health care provider outcomes.  相似文献

Parents may be reluctant to treat the feeding disorder of a chronically ill child who exhibits distressed behavior during feeding. In this study, we identified a child with chronic medical problems and a feeding disorder who cried during feedings. We introduced treatment components sequentially to address parental concerns about crying. First, we used a pacifier to reduce crying, and then we used a flipped spoon to increase mouth clean. The results showed that a sequential approach to treatment can be effective for children with complex medical and behavioral problems.  相似文献

In a birth cohort of 6281 men from Aberdeen, Scotland, social class of origin, childhood intelligence, childhood behavior disturbance and education were examined as predictors of status attainment in midlife (46 to 51 years). Social class of origin, intelligence and behavior disturbance were conceptualized as correlated predictors, whose effects were hypothesized to be partially mediated by educational qualifications. A structural equation model using Full Information Maximum Likelihood estimation confirmed that education had the strongest direct effect on status attainment at midlife. Furthermore, education partially mediated the effects of social class of origin and childhood intelligence, and fully mediated the effects of behavior disturbance on status attainment. Social class of origin, childhood intelligence and behavior disturbance were strongly inter-correlated. After controlling for these associations, educational and social status attainments were influenced to a considerably greater extent by childhood intelligence than by social class of origin.  相似文献

This study examined the role of character gender in prime time television health portrayals. A content analysis of 1,291 health-related storylines from three spring seasons (2004–2006) of the ten most popular American television programs measured the frequency of male and female characters in prominent roles and how storylines differed with the sex of the ill or injured character. Our analyses revealed a significantly greater number of male characters. Moreover, storylines with a male ill or injured character were more serious in tone, more likely to take place in a medical setting, and had higher educational value. Proportionally, there were some similarities in storylines across the sexes, however, the absolute differences are striking and may have unfortunate effects on viewers.  相似文献

In this article, self‐injurious behaviors are examined through the conceptual framework of relational cultural theory (RCT). As an emerging theoretical approach that takes into account the importance of relationships and relational goals, it is suggested that RCT be used in conjunction with mainstream approaches to treat self‐injury.  相似文献

In women, medroxyprogesterone acetate (MPA) is the most commonly used progestin component of hormone therapy (HT). In vitro, MPA negatively impacts markers of neuronal health and exacerbates experimentally-induced neurotoxicity. There is in vitro evidence that these factors are driven by GABAergic and neurotrophic systems. Whether these effects translate to a negative impact on brain function has not been tested in vivo, clinically or preclinically. Here we evaluate the mnemonic and neurobiological effects of MPA in the surgically menopausal rat. Aged ovariectomized (OVX) rats were given subcutaneous vehicle, natural progesterone, low-dose MPA or high-dose MPA. Multiple cognitive domains were analyzed via the water radial-arm maze (WRAM) and Morris maze (MM). Cognitive brain regions were assayed for changes in the GABAergic system by evaluating GAD protein, the synthesizing enzyme for GABA, and neurotrophins. On the WRAM, both progestin types impaired learning. Further, high-dose MPA impaired delayed memory retention on the WRAM, and exacerbated overnight forgetting on the MM. While neurotrophins were not affected by progesterone or MPA treatment, both progestin types altered GAD levels. MPA significantly and progesterone marginally decreased GAD levels in the hippocampus, and both MPA and progesterone significantly increased GAD levels in the entorhinal cortex. These findings suggest that MPA, the most commonly used progestin in HT, is detrimental to learning and two types of memory, and modulates the GABAergic system in cognitive brain regions, in aged surgically menopausal rats. These findings, combined with in vitro evidence that MPA is detrimental to neuronal health, indicates that MPA has negative effects for brain health and function.  相似文献

A well-established finding in the simulation literature is that participants simulate the positive argument of negation soon after reading a negative sentence, prior to simulating a scene consistent with the negated sentence (Kaup, Ludtke, & Zwaan, 2006; Kaup, Yaxley, Madden, Zwaan, & Ludtke, 2007). One interpretation of this finding is that negation requires two steps to process: first represent what is being negated then "reject" that in favour of a representation of a negation-consistent state of affairs (Kaup et al., 2007). In this paper we argue that this finding with negative sentences could be a by-product of the dynamic way that language is interpreted relative to a common ground and not the way that negation is represented. We present a study based on Kaup et al. (2007) that tests the competing accounts. Our results suggest that some negative sentences are not processed in two steps, but provide support for the alternative, dynamic account.  相似文献
