A plethora of data supports links between parenting behaviors and child anxiety, but few studies have examined factors that can contribute to variability in these relations. Adopting a biological sensitivity to context framework, this study explored the role of children's physiological stress reactivity in the links between emotion-parenting and child anxiety symptoms in a group of Chinese families. Sixty-one parent–child dyads (child Mage = 8.21 years, SD = 1.40, range = 6–12 years) participated in an acute stress protocol, from which children's physiological (cortisol and respiratory sinus arrhythmia) responses to a social speech task were recorded. Participants then completed questionnaires assessing parents’ emotion-parenting behaviors and children's anxiety symptoms. Results showed that the relation between supportive emotion-parenting and child anxiety was stronger in the context of greater child RSA suppression to acute stress, such that children higher in RSA suppression exhibited lower anxiety symptoms when supportive emotion-parenting was higher than when it was lower. Thus, these findings supported the biological sensitivity to context model. No significant moderation effect was detected for cortisol reactivity or recovery. Instead, exploratory mediation analyses showed that supportive emotion-parenting was negatively related to child anxiety via greater cortisol recovery. There was also a significant indirect path where unsupportive emotion-parenting was related to blunted cortisol recovery, which in turn was associated with higher child anxiety. The results highlight the importance of coaching parents to respond in supportive ways to children's emotional expressions, particularly in the context of greater child reactivity, to help buffer against childhood anxiety symptoms.  相似文献

Cross-culturally measurement invariant instruments are useful for the assessment of mental symptoms across cultures. The current study aimed to investigate the psychometric properties and measurement invariance of the Depression, Anxiety and Stress Scales (DASS-21) (DASS) across Pakistan and Germany. German participants were recruited through an online survey (N = 1323), while Pakistani participants were recruited through online survey or paper-and-pencil survey (N = 1841). The DASS-21 showed good reliability, construct and structure validity in both countries. The DASS-21 indicated partial weak (stress subscale) and partial strong measurement invariance (depression and anxiety subscales) between both countries. Latent mean comparison of depression and anxiety symptoms between Pakistani and German students indicated that Pakistani university students experience more symptoms of depression and anxiety. Results suggest that the DASS-21 could be used in Pakistan and Germany, but caution should be taken when making direct comparisons between the two countries.  相似文献

Impairment in semantic association has been reported in bipolar disorder (BD) and schizophrenia (SZ) patients and could underlie abnormal speech patterns in both disorders. In this study, we compared the electrophysiological semantic processing features in patients with these two disorders. Participants (n = 61; BD = 19; SZ = 19; healthy controls [HCs] = 23) were administered a semantic judgment task and event‐related potentials (ERPs) were recorded. Responses of the two patient groups were significantly slower than HCs, but comparable behavioral semantic priming effects were observed in both patient groups. The N400 priming effect was observed in all groups, with a delayed peak in the two patient groups. The N400 effect was enhanced for both BD and SZ patients over the left frontal and frontal pole region, but SZ patients showed additional reduction of N400 over the right posterior and occipital regions. The N400 mean amplitudes for related targets correlated with less severe negative symptoms in patients with SZ. Discriminant functional analysis using reaction time and N400 measures successfully classified 82% of the participants into their respective clinical groups. These results suggest that patients with BD and SZ have both overlapping and distinctive semantic processing dysfunction. These findings are consistent with the continuum conceptualization of these disorders, but also offer some support for the traditional Kraepelinian dichotomy.  相似文献

The present study aimed to examine the effect of incentive salience on the motivational behavior and pleasure experience of 35 healthy participants during reward pursuits. The findings suggest that high incentive salience promotes motivation in effort‐expenditure decision‐making, effort exertion, and pleasure experience.  相似文献

People attend to the same event or object by using a global or local processing style across different environments. Different physical environmental conditions, such as orderliness and disorderliness, activate different psychological states and produce different kinds of outcomes. However, previous work has rarely examined whether individuals exposed to different orderly or disorderly environments attend to the “global” or the “local” differently. Thus, in the current study, we conducted three behavioral experiments to directly examine the impact of disorder versus order cues on people's types of perceptual and conceptual processing (global vs. local). We asked participants to perform a typical Kimchi–Palmer figures task or a categorization task: with pre‐primed disorderly or orderly physical environmental pictures (Experiment 1), with basic visual pictures (Experiment 2), and imagining a real environment (Experiment 3). The results revealed that in any of the above operations, orderly experience led to global perceptual processing, whereas disorderly experience led to local perceptual processing. This difference in processing style was not influenced by the participants’ daily habits or their preference for the need for structure. However, this difference in perceptual processing style did not spill over to the conceptual processing style. These findings provide direct evidence of the effects of disorderliness versus orderliness on global versus local perceptual and conceptual processing and imply that environmental orderliness or disorderliness may functionally affect cognitive processing (i.e., how we see and think about events and objects). Thus, the findings creatively bridge several lines of research and shed light on a basic cognitive mechanism responsible for perceptions of order/disorder.  相似文献

Previous studies have documented that the perception of self‐motion direction can be extracted from the patterns of image motion on the retina (also termed optic flow). Self‐motion perception remains stable even when the optic‐flow information is distorted by concurrent gaze shifts from body/eye rotations. This has been interpreted that extraretinal signals—efference copies of eye/body movements—are involved in compensating for retinal distortions. Here, we tested an alternative hypothesis to the extraretinal interpretation. We hypothesized that accurate self‐motion perception can be achieved from a purely optic‐flow‐based visual strategy acquired through experience, independent of extraretinal mechanism. To test this, we asked human subjects to perform a self‐motion direction discrimination task under normal optic flow (fixation condition) or distorted optic flow resulted from either realistic (pursuit condition) or simulated (simulated condition) eye movements. The task was performed either without (pre‐ and posttraining) or with (during training) the feedback about the correct answer. We first replicated the previous observation that before training, direction perception was greatly impaired in the simulated condition where the optic flow was distorted and extraretinal eye movement signals were absent. We further showed that after a few training sessions, the initial impairment in direction perception was gradually improved. These results reveal that behavioral training can enforce the exploitation of retinal cues to compensate for the distortion, without the contribution from the extraretinal signals. Our results suggest that self‐motion perception is a flexible and adaptive process which might depend on neural plasticity in relevant cortical areas.  相似文献

There is a “positive–negative” debate on the development of the bottom-line mentality (BLM) concept. Previous research showed a relationship between BLM and unethical pro-organizational behaviour (UPB) and revealed that BLM positively affected UPB. This research aims to challenge this partial view and calls for a more balanced and comprehensive view of the BLM concept by revealing the potential negative influencing mechanism between BLM and UPB. Drawing from social information processing theory, we construct a moderated-mediation model to test the mediating mechanism through different individual-level processes in the Chinese context. Findings indicate that team BLM positively affects member UPB via state performance-prove goal orientation and perceived insider status and negatively affects member UPB via state performance-avoid goal orientation. These results confirm the overall positive relationship between team BLM and member UPB but also document the possible inhibitory mechanism of BLM on UPB. This study is the first to acknowledge the potential negative relationship between BLM and UPB, which deserves attention. This research also presents a complete picture of the BLM literature. The findings of this work have significant implications in enabling organizations to appropriately handle BLM and its relationship with UPB dynamically.  相似文献

自上世纪七十年代以来,随着视觉词汇加工领域的研究,多词素词的认知加工引起了研究者的广泛关注。文章对三十年来的研究进行综述和系统梳理,重点讨论词素在多词素词认知加工中的作用。虽然对词素加工的本质 (形或义的激活)仍未达成共识,但词素语义能否在多词素词加工的早期阶段得到激活已成为现今研究的焦点问题之一。相关研究大致可分为三个对立阶段:分解论与整体论之争、词素形式论与语义论之争、先形后义激活论与形义同时激活论之争。本文最后指出该研究领域尚未解决的问题并对未来研究进行了展望。  相似文献

本文详细描述了一种全自动化的行为检测方案。在自然饲养环境/检测环境(24/7)中, 我们测量了小鼠针对两个给食器中获得食物的比例与它们在相应给食器停留时长的比例进行匹配的精确性与准确性。该方案是对传统条件性习得 (trials-to-acquisition) 行为测验设备的改进, 可以检测动物时间间隔能力的精确性与准确性, 对定时目标选择的相关概率的效果, 以及记忆一天中从不同给食器中获得食物次数的精确性与准确性。该压缩系统避免了在整个实验过程中对小鼠的持握操作, 可忽略实验者/技术员的实验操作时间, 而且可以递送小鼠置入实验环境后, 7~9个实验日中全部3组实验流程产生的大量结果。其中, 第一个实验流程为单个24小时周期内完成的时间匹配能力的筛查, 它对动物的时间、空间估计能力的记忆机制进行精确检测。因此, 该系统允许在有限的实验空间、较短的实验周期内, 对大量的实验小鼠进行有可能存在的学习记忆能力缺陷进行大规模筛查。此外, 该系统运行所依赖的软件可以在公共开放平台获得。  相似文献
