During infancy, cardiac vagal modulation has been associated with attentional and social engagement behaviors. While studies have shown that infants display a behavioral repertoire that enables them to interact with others by being able to regulate themselves in order to attend to and to discriminate emotional and social cues, vagal modulation to sensory stimuli and its association with behavioral outcomes at early ages remains to be addressed. In this study, we analyzed the cardiac vagal response of 1‐month‐old infants to two auditory stimuli intensities and whether vagal response was associated with social interactive and self‐regulatory abilities. Therefore, we recorded cardiac and respiratory physiological responses in 28 infants using a Biopac System. Neurobehavioral assessment was performed using the Neonatal Behavioral Assessment Scale. We observed increased respiratory sinus arrhythmia (RSA) amplitude to both auditory stimuli intensities when compared to baseline. No intensity effect was found for the RSA response. Additionally, we observed that higher RSA amplitude to both auditory stimuli was positively correlated with adjusted self‐regulatory behaviors, suggesting a convergence between multiple measures assessing infants' state regulation. Results are discussed in light of 1‐month‐old infants' auditory stimuli processing and its implications for regulatory behaviors and the emergent social‐like behaviors.  相似文献

The role of information processing in understanding people's responses to risk information has recently received substantial attention. One limitation of this research concerns the unavailability of a validated questionnaire of information processing. This article presents two studies in which we describe the development and validation of the Information‐Processing Questionnaire to meet that need. Study 1 describes the development and initial validation of the questionnaire. Participants were randomized to either a systematic processing or a heuristic processing condition after which they completed a manipulation check and the initial 15‐item questionnaire and again two weeks later. The questionnaire was subjected to factor reliability and validity analyses on both measurement times for purposes of cross‐validation of the results. A two‐factor solution was observed representing a systematic processing and a heuristic processing subscale. The resulting scale showed good reliability and validity, with the systematic condition scoring significantly higher on the systematic subscale and the heuristic processing condition significantly higher on the heuristic subscale. Study 2 sought to further validate the questionnaire in a field study. Results of the second study corresponded with those of Study 1 and provided further evidence of the validity of the Information‐Processing Questionnaire. The availability of this information‐processing scale will be a valuable asset for future research and may provide researchers with new research opportunities.  相似文献

By integrating cognitive diversity into debiasing literature, this paper contributes towards opening the black box of executive judgment. Based on information processing theory we investigate the role of cognitive diversity in strategic decision making. We apply a vignette-based experimental research design to examine the effect of cognitive diversity in teams on decision maker's illusion of control. The results of these experiments provide evidence for a positive influence of high cognitive diversity for debiasing judgment while similarly indicating no such effect for groups with low cognitive diversity. These findings suggest that group composition aspects can play an important role for improving judgment in decision making teams and open promising new avenues for studying debiasing in behavioral strategy research.  相似文献

The paper investigates various nonparametric models including regression, conditional distribution, conditional density and conditional hazard function, when the covariates are infinite dimensional. The main contribution is to prove uniform in bandwidth asymptotic results for kernel estimators of these functional operators. Then, the application issues, involving data-driven bandwidth selection, are discussed.  相似文献

有关隐喻认知研究的一个核心问题是:隐喻加工机制与一般言语理解相比是否具有独特性以及隐喻理解伴随的神经生理机制是否有其独特的模式? 对此问题的回答需要对隐喻性质进行区分。常见的熟悉隐喻可进一步区分为词源性隐喻与引发性隐喻,其中词源性隐喻的隐喻义属于词语多个词义中的一个延伸义,而引发性隐喻则是将两个分属于不同概念领域的概念进行非字面的语义联结。词源性隐喻句和引发性隐喻句的理解包含了与一般语义句理解不同的加工内容。相比一般句,词源性隐喻句特异性地激活了与语义竞争相关的左侧颞中回、颞上回以及与加工深度有关的额下回,而引发性隐喻句则在左侧额下回有更多激活。隐喻的内在加工过程和神经机制并不单一,探讨隐喻理解与一般语义理解的异同需要考虑具体的隐喻性质。  相似文献

证券分析师个人特征是其能力的重要表征.文章选取2007-2014年我国资本市场相关数据,研究了证券分析师的性别对盈余预测偏差的影响,以及盈余预测偏差的时间序列特征,实证结果显示:第一,整体上男性分析师的盈余预测偏差大于女性分析师;第二,男性分析师对于盈余预测偏差的纠正能力高于女性分析师;第三,随着对公司跟踪时间的增加,男性分析师的盈余预测偏差下降速度更快.研究结果说明,对于分析师跟踪时间较短的公司,女性分析师的盈余预测偏差较小,而对于受分析师长期跟踪的公司,男性分析师的盈余预测结果更准确.研究结论对投资者依据分析师性别判定其盈利预测准确性具有重要意义.  相似文献

木材经营加工产业是一项古老的产业,也是现代林业产业体系中的重要产业,具有极大的发展空间。当前,中国木材经营加工产业发展面临诸多的制度瓶颈,林业行政部门在实施木材经营加工许可制度时存在扩大管制地理空间、压缩木材经营加工企业市场空间、随意设定行政许可有效期和年检等问题。要发展木材经营加工产业,最优选择是取消木材经营加工许可制度,次优选择是全面规范木材经营加工许可制度,包括严格控制地理空间范围、简化木材经营加工许可申请材料、取消年检等。  相似文献

为了探究消费者在网络购物时品牌熟悉度与商家促销方式对其购买意愿的交互影响,模拟了网络购物情景,利用消费者的双系统信息处理理论(情感处理系统、认知处理系统)对消费者的购买意愿进行分析,检验了品牌熟悉度(高和低)和网络促销方式(价格促销与非价格促销)对消费者购买意愿的交互影响以及作用机制。结果表明,对于高熟悉度品牌,价格促销比非价格促销更能引起消费者的购买意愿,其中介机制为情感处理系统;对于低熟悉度品牌,非价格促销比价格促销更能引起消费者的购买意愿,其中介机制为认知处理系统。  相似文献

Previous studies examined how mood affects children's accuracy in matching emotional expressions and labels (label‐based tasks). This study was the first to assess how induced mood (positive, neutral, or negative) influenced five‐ to eight‐year‐olds' accuracy and reaction time using both context‐based tasks, which required inferring a character's emotion from a vignette, and label‐based tasks. Both tasks required choosing one of four facial expressions to respond. Children responded more accurately to label‐based questions relative to context‐based questions at the age of five to seven, but showed no differences at the age of eight, and when the emotional expression being identified was happiness, sadness, or surprise, but not disgust. For the context‐based questions, children were more accurate at inferring sad and disgusted emotions compared with happy and surprised emotions. Induced positive mood facilitated five‐year‐olds' processing (decreased reaction time) in both tasks compared with induced negative and neutral moods. Results demonstrate how task type and children's mood influence children's emotion processing at different ages.  相似文献
