Being exposed to more data and devices with tracking functions than ever, quantification is concerned by an increasing number of consumers. The self‐reflection from data may raise consumers' awareness of their own goals to better modify their behaviors. This paper describes consumers' reaction to quantification and confirms its motivational effect in goal pursuit. First, we investigate the motivational effect of quantification and reveal its internal mechanism from the individual–community perspective. Results show that quantification can promote consumers' goal pursuit motivation. A quantified (vs. nonquantified) way to track progress in pursuit of a goal can strengthen consumers' self‐empowerment (individual level) and difference‐insight (community level), thus enhancing the goal pursuit motivation. Second, we explore the moderating effect of some factors on the motivational effect of quantification. Results confirm that self‐empowerment can be enhanced with high data–color consistency, and difference‐insight can be increased with low outcome–process consistency. Third, we identify the validity of various data presentation modes. Using the interactive progress framing (to date with to go) together with the several subunits mode to deliver data in different progress stages is found to be an effective way to promote consumers' goal pursuit motivation. 相似文献

Mental health systems need scalable solutions that can reduce the efficacy–effectiveness gap and improve mental health outcomes in community mental health service settings. Two major challenges to delivery of high-quality care are providers’ fidelity to evidence-based treatment models and children’s and caregivers’ engagement in the treatment process. We developed a novel, tablet-based application designed to enhance via technology the quality of delivery of trauma-focused cognitive-behavioral therapy (TF-CBT). We piloted its use in four community mental health service organizations using a blocked randomized controlled trial to examine the feasibility of implementing tablet-facilitated TF-CBT versus standard TF-CBT with 13 providers and 27 families. Provider fidelity and child engagement in treatment were observationally measured via session audio recording. Parent and child perceptions of the tablet application were assessed using structured interviews and mixed-method analyses. Providers actively and appropriately used tablet TF-CBT to facilitate treatment activities. Providers and families expressed high satisfaction with its use, demonstrating acceptability of this approach. Youth and caregivers in both conditions reported high alliance with their providers. Overall, we found that tablet-facilitated treatment is accepted by providers and families and may be integrated into mental health treatment with minimal training. Further study is needed to examine the extent to which technology-based applications may enhance the reach, quality, and clinical outcomes of mental health treatment delivered to children and families. 相似文献

通过操纵Flanker任务相对于视觉工作记忆任务的呈现位置, 探讨在视觉工作记忆编码和保持阶段, 精度负载和容量负载对注意选择的影响。行为结果发现, Flanker任务呈现位置和视觉工作记忆负载类型影响注意选择; ERP结果发现, 在保持阶段, 当搜索目标和干扰项不一致时, 负载类型影响N2成分。研究表明, 在编码阶段, 视觉工作记忆负载主要通过占用更多知觉资源降低干扰效应, 支持知觉负载理论; 而在保持阶段, 当Flanker任务位于记忆项内部时, 两类负载在工作记忆表征过程中不同的神经活动导致投入到注意选择的认知控制资源不同, 可能是两类负载影响保持阶段注意选择的机制。 相似文献

The authors examined cultural and individual differences in the relation between daily events and daily satisfaction. In a preliminary study, they established cross-cultural equivalence of 50 daily events. In the main study, participants in the United States, Korea, and Japan completed daily surveys on the 50 events and daily satisfaction for 21 days. The multilevel random coefficient model analyses showed that (a) the within-person association between positive events and daily satisfaction was significantly stronger among Asian American, Korean, and Japanese participants than among European American participants and (b) the within-person association between positive events and daily satisfaction was significantly weaker among individuals high in global life satisfaction than among those low in global life satisfaction. The findings demonstrate a weaker effect of positive events on daily well-being among individuals and cultures high in global well-being. 相似文献

Superoxide has been shown to be critically involved in several pathological manifestations of aging animals. In contrast, superoxide also can act as a signaling molecule to modulate signal transduction cascades required for hippocampal synaptic plasticity. Mitochondrial superoxide dismutase (SOD-2 or Mn-SOD) is a key antioxidant enzyme that scavenges superoxide. Thus, SOD-2 may not only prevent aging-related oxidative stress, but may also regulate redox signaling in young animals. We used transgenic mice overexpressing SOD-2 to study the role of mitochondrial superoxide in aging, synaptic plasticity, and memory-associated behavior. We found that overexpression of SOD-2 had no obvious effect on synaptic plasticity and memory formation in young mice, and could not rescue the age-related impairments in either synaptic plasticity or memory in old mice. However, SOD-2 overexpression did decrease mitochondrial superoxide in hippocampal neurons, and extended the lifespan of the mice. These findings increase our knowledge of the role of mitochondrial superoxide in physiological and pathological processes in the brain. 相似文献

A Web-based interface has been developed to facilitate researchers in collecting language history information online. Most
researchers use their own versions of language history questionnaires for specific studies in second language acquisition.
Although these versions of questionnaires all differ from one another in some respects, there is a significant amount of overlap
between them. Here we identify the crucial dimensions that most investigators consider important to include in such a questionnaire.
We have examined the most commonly asked questions in 41 published questionnaires, and on the basis of our analyses we propose
a general L2 language history questionnaire. Subjects can enter some or all of the information on the Web, and the results
are automatically generated as an RTF output file on the user’s desktop. 相似文献

The Proust phenomenon is an enduring piece of folk wisdom that asserts that odors are particularly powerful autobiographical memory cues. We provide a more formal exposition of this phenomenon and test it in two experiments, using a novel double-cuing methodology designed to negate less interesting explanations. In both studies, recall of an autobiographical event was initially cued by a verbal label (an odor name) for a fixed period, following which a second, extended recall attempt was cued by the same verbal label, the relevant odor, an irrelevant odor, or a visual cue. The focus of Experiment 1 was participants' ratings of the emotional quality of their autobiographical memories. In Experiment 2, content analysis was employed to determine the quantity of information in participants' recollections. Results revealed that odor-cued autobiographical memories were reliably different in terms of qualitative ratings and reliably superior in the amount of detail yielded. Moreover, visual cues and incongruent olfactory cues appeared to have a detrimental effect on the amount of detail recalled. These results support the proposal that odors are especially effective as reminders of past experience. 相似文献
