Funeral rituals perform important social functions for families and communities, but little is known about the motives of people planning funerals. Using mixed methods, we examine funeral planning as end-of-life relational spending. We identify how relational motives drive and manifest in funeral planning, even when the primary recipient of goods and services is dead. Qualitative interviews with consumers who had planned pre-COVID funerals (N = 15) reveal a caring orientation drives funeral decision-making for loved ones and for self-planned funerals. Caring practices manifest in three forms: (a) balancing preferences between the planner, deceased, and surviving family; (b) making personal sacrifices; and (c) spending amount (Study 1). Archival funeral contract data (N = 385) reveal supporting quantitative evidence of caring-driven funeral spending. Planners spend more on funerals for others and underspend on their own funerals (Study 2). Preregistered experiments (N = 1,906) addressing selection bias replicate these results and find generalization across different funding sources (planner-funded, other-funded, and insurance; Studies 3A–3C). The findings elucidate a ubiquitous, emotional, and financially consequential decision process at the end of life.  相似文献

近年来, 诸多学者将研究视角投向群体情绪感染, 即群体内部成员间的情绪感染交互过程。群体情绪感染不仅包括个体间的直接情绪感染, 而且受到群体认同、共同行为以及集体规则等多方面因素的影响。基于集体仪式的过程框架, 分析集体仪式的三要素即同步动作、共享注意和共享意义与群体情绪感染的关系, 能更清楚阐述群体情绪感染的发生与增强过程:集体仪式通过自我定型和自我锚定增强群体认同, 在认同基础上的身份融合促进个体关注群体身份, 导致个体的自我表征发生转化, 社会自我的突出使其更容易接受群体的观点和情感表达, 最终增强了群体情绪感染。未来研究应进一步考察群体情绪感染的影响因素并丰富其测量方法。  相似文献

Task effects in semantic processing were investigated by contrasting the neural activation associated with two semantic categorization tasks (SCT) using event-related fMRI. The two SCTs involved different decision categories: is it an animal? vs. is it a concrete thing? Participants completed both tasks and, across participants, the same core set of items were presented in both tasks. Results showed task differences in the neural activation associated with these items: in the animal SCT there was greater activation in a number of frontal and temporal regions, including left superior and middle temporal gyri, while in the concrete SCT there was greater activation in left medial frontal gyrus and bilaterally in the precentral gyri. These results are interpreted as evidence of top-down modulation of semantic processing; participants make adjustments to optimize performance in a given task and these adjustments have consequences for the activation observed.  相似文献

Confrontation naming tasks assess cognitive processes involved in the main stage of word production. However, in fMRI, the occurrence of movement artifacts necessitates the use of covert paradigms, which has limited clinical applications. Thus, we explored the feasibility of adopting multichannel functional near-infrared spectroscopy (fNIRS) to assess language function during covert and overt naming tasks. Thirty right-handed, healthy adult volunteers underwent both naming tasks and cortical hemodynamics measurement using fNIRS. The overt naming task recruited the classical left-hemisphere language areas (left inferior frontal, superior and middle temporal, precentral, and postcentral gyri) exemplified by an increase in the oxy-Hb signal. Activations were bilateral in the middle and superior temporal gyri. However, the covert naming task recruited activation only in the left-middle temporal gyrus. The activation patterns reflected a major part of the functional network for overt word production, suggesting the clinical importance of fNIRS in the diagnosis of aphasic patients.  相似文献

The paper discusses problems inherent in the secularist project,by an examination of secularisms in India and China.Different motives,historical backgrounds,political situations and cultural considerations etc.have led to different paths and results in the two countries’ secularization efforts in modern times,the study of which will further our understanding of the secularist project.  相似文献

Growth arrest and DNA damage-inducible β (Gadd45b) has been shown to be involved in DNA demethylation and may be important for cognitive processes. Gadd45b is abnormally expressed in subjects with autism and psychosis, two disorders associated with cognitive deficits. Furthermore, several high-throughput screens have identified Gadd45b as a candidate plasticity-related gene. However, a direct demonstration of a link between Gadd45b and memory has not been established. The current studies first determined whether expression of the Gadd45 family of genes was affected by contextual fear conditioning. Gadd45b, and to a lesser extent Gadd45g, were up-regulated in the hippocampus following contextual fear conditioning, whereas Gadd45a was not. Next, Gadd45b knockout mice were tested for contextual and cued fear conditioning. Gadd45b knockout mice exhibited a significant deficit in long-term contextual fear conditioning; however, they displayed normal levels of short-term contextual fear conditioning. No differences between Gadd45b knockout and wild-type mice were observed in cued fear conditioning. Because cued fear conditioning is hippocampus independent, while contextual fear conditioning is hippocampus dependent, the current studies suggest that Gadd45b may be important for long-term hippocampus-dependent memory storage. Therefore, Gadd45b may be a novel therapeutic target for the cognitive deficits associated with many neurodevelopmental, neurological, and psychiatric disorders.  相似文献

Sales managers need a practical means for evaluating returns from investments in sales technology implementations (including sales automation and sales-based customer relationship management systems). This research proposes a behavioral process model approach that can be applied to evaluate sales technology implementations. We develop and test the model with data collected from the sales force of a major consumer packaged goods company. The results indicate that a salesperson’s technology orientation has a direct impact on internal role performance, and it affects performance with customers through a double-mediated mechanism involving the effective use of information and smart selling behaviors (planning and adaptive selling). Sales managers can influence sales technology orientation by providing better internal technology support, considering technology orientation along with customer’s approval of technology in account assignments, and understanding the probability of negative effects through a salesperson’s experience. In our sample, salesperson experience correlates with age, suggesting a “generation gap” effect on sales technology orientation.  相似文献

Drawing on the social information process perspective, we hypothesized that transformational leadership fosters psychological safety climate leading to enhanced individual-level creative process engagement. Furthermore, psychological safety climate was hypothesized to strengthen the relationship between creative process engagement and employee creativity. The hypothesized model was tested with data obtained from a sample of 358 employees and their supervisors from two organizations in the People’s Republic of China. Results of hierarchical linear modeling analysis revealed that transformational leadership influenced creative process engagement via psychological safety climate. Furthermore, psychological safety climate moderated the creative process engagement–creativity relationship such that the relationship was stronger in groups with high rather than low psychological safety climate.  相似文献

研究选取上海111名(男生48名, 女生63名, 平均年龄11.97岁)初中学生(数学学业不良学生55名与数学学业优秀学生56名), 根据国家数学课程标准, 将数学划分为数与代数、空间与几何两部分, 又从空间与几何领域中选取初一数学学业知识点—— 轴对称和中心对称图形, 分析在不同内容知识领域的解答过程中所涉及的工作记忆成分。结果发现:(1)数与代数学习需要中央执行系统、视觉-空间模板、语音环路三个成分的共同作用; 空间与几何学习主要受到视觉-空间模板和中央执行系统的影响, 但不存在语音环路的影响。(2)对轴对称与中心对称图形任务的成绩影响最大的是视觉-空间模板, 其次是中央执行系统, 语音环路对该任务作用不明显。两个研究说明工作记忆在初中不同年级的各类数学学业任务中具有不同的作用, 中央执行系统和视觉-空间模板相对更具有普遍性作用, 语音环路具有特殊性作用, 并且随着年龄增高, 视觉-空间模板对数学学业任务的作用更为突显。  相似文献
