Theory and research on self‐regulation, emotional adjustment, and interpersonal processes focus increasingly on parasympathetic functioning, using measures of vagally mediated heart rate variability (vmHRV) or respiratory sinus arrhythmia (RSA). This review describes models of vmHRV in these areas, and issues in measurement and analysis. We propose a framework organizing theory and research as examining (a) vmHRV as an individual difference or a situational response, and (b) resting, reactive, or recovery levels. Evidence supports interpretation of individual differences in resting vmHRV as a broad biomarker for adaptive functioning, but its specificity and underlying mechanisms require elaboration. Individual differences in vagal reactivity (i.e., trait‐like differences in vmHRV decreases during challenge or stress) are less commonly studied in adults and results are mixed. Many stressors and challenges evoke temporary decreases in vmHRV, and in some research self‐regulatory effort evokes increases. In a smaller literature, positive interpersonal experiences and some restorative processes increase resting vmHRV, whereas depletion of self‐regulatory capacity through related effort decreases it. Greater attention to conceptual distinctions regarding vmHRV constructs and several methodological issues will strengthen future research. Importantly, researchers should exercise caution in equating vmHRV with specific psychosocial constructs, especially in the absence of converging assessments and precise experimental manipulations. 相似文献

Theoretical models and research that aim to identify antecedents of participation in physical activities or sport can measure antecedents of physical activity behaviour through instruments that involve subjective predictions. In this article, we argue that such instruments may not reflect physical activity experiences or behaviour accurately because people are not very good predictors of future states. Additionally, we propose that mispredictions may be predictable because they are “caused” by tendencies to neglect processes related to hedonic adaptation and competing alternatives. We also suggest that it may be possible to improve measurement of antecedents through methods that focus respondents' attention on factors that cause mispredictions or through experiential sampling methods. 相似文献

This study aimed to assess the impact of target faces’ skin tone and perceivers’ skin tone on the participants’ attractiveness judgment regarding a symmetrical representative range of target faces as stimuli. Presented with a set of facial features, 240 Mozambican adults rated their attractiveness along a continuous scale. ANOVA and Chi-square were used to analyze the data. The results revealed that the skin tone of the target faces had an impact on the participants’ attractiveness judgment. Overall, participants preferred light-skinned faces over dark-skinned ones. This finding is not only consistent with previous results on skin tone preferences, but it is even more powerful because it demonstrates that the light skin tone preference occurs regardless of the symmetry and baseline attractiveness of the stimuli. 相似文献

The study investigates the idea that feeling good and functioning well-being are regulated by two different mechanisms: hedonic and eudaimonic. At the state level it is assumed that happiness is a hedonic feeling typically experienced when life is easy or a goal is reached. Inspiration is a eudaimonic feeling typically experienced when facing challenges in the process of goal attainment. At the trait level, we assume that personal growth is connected with eudaimonic rather than hedonic mechanisms. These assumptions were confirmed with data from 465 employees of the Occupational Health Services in Norway using day reconstruction method. Multilevel analyses showed that complex work situations increased inspiration and decreased happiness. Personal growth had a stronger effect on inspiration than on happiness. Our results support the idea that pleasant feelings (hedonia) and optimal functioning (eudaimonia) have different roles to play in the regulation of behavior, and therefore need to be distinguished from one another. 相似文献

Presenting two targets in a rapid visual stream will frequently result in the
second target (T2) being missed when presented shortly after the first target
(T1). This so-called attentional blink (AB) phenomenon can be
reduced by various experimental manipulations. This study investigated the
effect of combining T2 with a non-specific sound, played either simultaneously
with T2 or preceding T2 by a fixed latency. The reliability of the observed
effects and their correlation with potential predictors were studied. The tone
significantly improved T2 identification rates regardless of tone condition and
of the delay between targets, suggesting that the crossmodal facilitation of T2
identification is not limited to visual-perceptual enhancement. For the
simultaneous condition, an additional time-on-task effect was observed in form
of a reduction of the AB that occurred within an experimental session. Thus,
audition-driven enhancement of visual perception may need some time for its full
potential to evolve. Split-half and test-retest reliability were found
consistently only for a condition without additional sound. AB magnitude
obtained in this condition was related to AB magnitudes obtained in both sound
conditions. Self-reported distractibility and performance in tests of divided
attention and of cognitive flexibility correlated with the AB magnitudes of a
subset but never all conditions under study. Reliability and correlation results
suggest that not only dispositional abilities but also state factors exert an
influence on AB magnitude. These findings extend earlier work on audition-driven
enhancement of target identification in the AB and on the reliability and
behavioural correlates of the AB. 相似文献

This study investigates the relationship between emotion, reason and perceived risk. Evidence is presented using an aggregative data set of 146 products and services which were randomly selected from the SIC (Standard Industrial Classification Codes) manual. It is demonstrated that emotional factors account for a significant and substantial portion of the variance in perceived risk even after the effect of rational factors (perceived differences between alternatives) has been taken into account. It is suggested that emotion be explicitly modelled in future conceptualisations of perceived risk. Copyright © 2002 Henry Stewart Publications. 相似文献

消费者的权力感与冲动购买 总被引:1,自引:0,他引:1
本文探究消费者的权力感对冲动购买的影响。通过3组实验研究发现,权力感影响人们对不同类型产品的冲动购买意愿,其机制在于高(低)权力感的人面对实用品(享乐品)有更高的信息加工流畅性;进一步,当高权力感的人具有享乐目标时,他们反而在享乐品上表现出更高的冲动购买意愿。最后,本文就研究结果的理论贡献及管理启示进行了探讨,并提出了本研究的局限性和未来研究的方向。 相似文献

探讨超音段(如声调)与音段信息的共同作用机制, 对口语词汇识别研究具有重要的理论意义。有研究探讨了声调在口语词汇语义通达阶段的作用, 但在相对早期的音节感知阶段, 声调与声母、韵母的共同作用机制还缺乏系统的认识。本研究采用oddball实验范式, 通过两个行为实验考察了声调在汉语音节感知中的作用。实验1发现检测声调和声母变化的时间没有差异, 均比检测韵母变化的时间长, 表明在汉语音节感知中对声调的敏感性不及韵母。实验2发现声母和韵母的组合并没有明显优于对韵母的觉察, 但声调与声母或韵母的同时变化都促进了被试对偏差刺激的觉察, 表明声调通过与声母、韵母的结合来共同影响汉语音节的感知加工。研究结果在认知行为层面为声调在音节感知中的作用机制提供了直接的实验证据, 为进一步探讨超音段与音段信息共同作用的认知神经机制提供了基础。 相似文献
