根据血压昼夜节律,观察给药时间对血压晨峰的影响。256例原发性高血压患者,经24h动态血压监测分为超杓型(n=49)、杓型(n=127)和非杓型(n=80)3组;各组再分为清晨服药组和晚上服药组。用药6周,比较用药前后血压昼夜节律及血压晨峰的变化,发现在改变血压昼夜节律及降低血压晨峰方面,超杓型组清晨服药优于晚上服药,非杓型组晚上服药优于清晨服药;杓型组清晨服药与晚上服药均能降低晨峰值,提示根据个体血压昼夜节律选择服药时间能更好地控制血压晨峰。 相似文献

By roughly 6 years of age, children acquire the stereotype that men are more competent than women in science, technology, engineering, and mathematics (STEM), potentially leading to greater trust in scientific information provided by men. This study tested whether 3- to 8-year-old children differentially endorsed conflicting information about science and toys presented by male and female informants depicted as a ‘man’ and ‘woman’ (Exp1) or ‘scientists’ (Exp2). Children were expected to endorse toy testimony from gender-matched informants; thus, the key question concerned endorsement of science testimony. In Exp1 (N = 149), boys and girls showed a same-gender informant preference for toy testimony; however, girls endorsed the male informant's testimony more for science than for toys – but only when tested by a male experimenter. In Exp2 (N = 264), boys and girls showed a same-gender preference, irrespective of content. Findings suggest that STEM-related gender stereotypes might lead girls to trust scientific information presented by men over women in certain contexts. 相似文献

Relatively little is known about features of moral reasoning among young children with callous-unemotional (CU) traits (e.g., lack of guilt and empathy). This study tested associations between CU traits and emotion attributions (i.e., identification of others’ emotional states) and justifications (i.e., explanations for those emotional states), across social scenarios involving discreet versus salient distress cues. The participants were boys aged 6-to-10 years (N = 50; Mage = 7 years 7 months), who were interviewed about 12 hypothetical scenarios (eight with discreet and four with salient distress cues). Regression models indicated that CU traits, in interaction with high levels of antisocial behaviour, were associated with reduced emotion attributions of fear in discreet but not salient immoral scenarios. Higher CU traits were also associated with reduced justifications referencing others’ welfare in discreet scenarios, and increased references to action-orientated justifications in salient scenarios. These findings suggest that CU traits are associated with early moral reasoning impairments and that salience of distress may be important to these processes. 相似文献

Research with children has demonstrated that both positive vicarious learning (modelling) and positive verbal information can reduce children's acquired fear responses for a particular stimulus. However, this fear reduction appears to be more effective when the intervention pathway matches the initial fear learning pathway. That is, positive verbal information is a more effective intervention than positive modelling when fear is originally acquired via negative verbal information. Research has yet to explore whether fear reduction pathways are also important for fears acquired via vicarious learning. To test this, an experiment compared the effectiveness of positive verbal information and positive vicarious learning interventions for reducing vicariously acquired fears in children (7–9 years). Both vicarious and informational fear reduction interventions were found to be equally effective at reducing vicariously acquired fears, suggesting that acquisition and intervention pathways do not need to match for successful fear reduction. This has significant implications for parents and those working with children because it suggests that providing children with positive information or positive vicarious learning immediately after a negative modelling event may prevent more serious fears developing. 相似文献

Recent studies have emphasized the importance of childhood memories of threatening experiences and submissiveness in a diversity of psychological disorders. The purpose of this work was to study their specific relationship with hallucination proneness and ideas of reference in healthy subjects. The ELES scale for measuring memory of adverse childhood experiences, the DES ‐II scale for measuring dissociation, the LSHS ‐R scale for measuring hallucination proneness, and the REF for ideas of reference were applied to a sample of 472 subjects. A positive association was found between childhood memories of adverse experiences and hallucination proneness and ideas of reference, on one hand, and dissociation on the other. A mediation analysis showed that dissociation was a mediator between the memory of adverse childhood experiences and hallucination proneness on one hand, and ideas of reference on the other. When the role of mediator of the types of dissociative experiences was studied, it was found that absorption and depersonalization mediated between adverse experiences and hallucination proneness. However, this mediating effect was not found between adverse experiences and ideas of reference. The relationship between these last two variables was direct. The results suggest that childhood memories of adverse experiences are a relevant factor in understanding hallucination proneness and ideas of reference. Similarly, dissociation is a specific mediator between adverse childhood experiences and hallucination proneness. 相似文献
