This study examined the role of retrieval context in implicit priming by manipulating percentage of word-stem index as shallow and deep processing while performing a word-stem completion task. 80 subjects were randomly divided into four groups each of 20 subjects: shallow processing or deep processing with few retrieval indices, and shallow processing or deep processing with many retrieval indices. Analysis indicated that proportion of word-stem completion was significantly higher for studied words than for nonstudied words in all four groups and that the subjects in the groups with many retrieval indices had a significantly increased proportion of word-stem completion between studied and nonstudied words than those in the groups with few retrieval indices. Postquestionnaire analysis indicated that more previously studied items were retrieved if many studied items were available during implicit word-stem completion and that only a small proportion of word-stem completion was finished with studied words by the subjects who were aware of the prior studied and test word relations in all four groups. It was concluded that having more studied words retrievable contributed to more being retrieved and that involuntary awareness had very limited influence on the priming in the implicit word-stem completion. 相似文献

The aim of this study was to look at motivations behind altruistic behavior in virtual communities by studying the sharing of game tips by experienced gamers. We examine several possible motivations (pure altruism, generalized reciprocity, and reputation) and qualitatively analyze tip types in terms of usefulness, visibility, and skill level. We found that in games that do not support a "performance stage" for skill demonstration, players often share game tips as a strategy to attract attention. To a certain degree, reciprocity can be used to explain small favor exchanges, but earning social reputation is often a much stronger motivating factor. 相似文献

Neuronal substrates of relapse to cocaine-seeking behavior: role of prefrontal cortex 总被引:2,自引:0,他引:2
The return to drug seeking, even after prolonged periods of abstinence, is a defining feature of cocaine addiction. The neural circuitry underlying relapse has been identified in neuropharmacological studies of experimental animals, typically rats, and supported in brain imaging studies of human addicts. Although the nucleus accumbens (NAcc), which has long been implicated in goal-directed behavior, plays a critical role in this circuit, the prefrontal cortex (PFC) appears to process the events that directly trigger relapse: exposure to acute stress, cues previously associated with the drug, and the drug itself. In this paper, we review animal models of relapse and what they have revealed about the mechanisms underlying the involvement of the NAcc and PFC in cocaine-seeking behavior. We also present electrophysiological data from PFC illustrating how the hedonic, motor, motivational, and reinforcing effects of cocaine can be analyzed at the neuronal level. Our preliminary findings suggest a role for PFC in processing information related to cocaine seeking but not the hedonic effects of the drug. Further use of this recording technology can help dissect the functions of PFC and other components of the neural circuitry underlying relapse. 相似文献

As China opens its door to the world, suicide research is making rapid progress using methods and instruments developed in the West. This is a feasibility study of the psychological autopsy methodology applied in China, with its emphasis on the social and cultural environments. With samples of 66 completed suicides and 66 community normal living controls, the authors found that it is feasible to interview at least two informants for each suicide case and each control, between 2 and 6 months after the suicide. With the Chinese-cultivated contacting method of recruiting cases, the refusal rate is nearly zero. The Western-developed methodology per se proved to be valid in the Chinese culture. Ethical considerations in the context of Chinese culture are as important as in the West. Psychological autopsy technique is shown to be an equally applicable method for the study of completed suicides in Chinese culture as it is in the West. Future epidemiological research on Chinese suicide should use the psychological autopsy method to collect data from larger samples in order to increase our understanding of the risk factors for Chinese suicides. 相似文献

Extant literature suggests that consumers derive more happiness from experiences (e.g., vacations) than from material possessions (e.g., furniture). However, this literature typically pits material against experiential consumption, treating them as a single bipolar construct of their relative dominance: more material or more experiential. This focus on relative dominance leaves unanswered questions regarding how different levels of material and experiential qualities each contribute to happiness. Four preregistered studies (N = 3,288), using hundreds of product categories, measured levels of material and experiential qualities using two unipolar items. These studies investigate recalled, evoked, and anticipated happiness. Results show a more nuanced view of the experiential advantage that is critical for future research and consumer theory: material and experiential qualities both have positive relationships with happiness. Further, there is no inherent trade-off between experiential and material qualities: consumers can enjoy consumption that is high on both (e.g., swimming pools and home improvements). 相似文献

The main purpose of this study is to explore the Christian response to the current ecological crisis by examining three statements using a method of theological reflection: Evangelii Gaudium (EG), Together towards Life (TTL), and The Cape Town Commitment (CTC). The three statements request Christians’ care for creation, which is now threatened. In contemplating the ecological crisis, the three statements call attention to the widespread abuse and destruction of the Earth due to an economic system that accelerates consumerism and human greed. To overcome this ecological crisis, Pope Francis recalls the joy of the gospel overflowing from the Trinity; TTL and CTC echo this, drawing their faith tradition from the Trinity with widening understanding of God who is creator, redeemer, and sustainer. The three statements also identify the rest of creation as the new poor in order to recall that the suffering of the poor and the suffering of the earth are one, inseparable from the suffering of Jesus. Finally, this study examines the three statements in relation to the spirituality of ecological themes. In particular, EG and TTL discern a false spirituality that is a form of individualism and a theology of prosperity, but suggest a spirituality that is referred to as either transformative spirituality or mystical fraternity. The study concludes that it is time to turn to the cosmological dimension of spirituality and theology for fraternity with God's creation and the future of the earth community. 相似文献

Similarity as threat: A motivational explanation of self–other similarity judgment asymmetry

People tend to judge others to be more similar to themselves than themselves are to others. This self–other similarity judgment asymmetry was often explained by a cognitive model. However, some findings were inconsistent with this model, implying that there might be complementary processes underlying such asymmetry. Although a motivational explanation has been proposed to account for the asymmetry, little evidence has been accumulated to verify this explanation and differentiate it from the cognitive model. The current research tested both the core assumption of the motivational explanation as well as a hypothesis derived only from it. Results suggest that the perception of oneself as being similar to others was more threatening to people's uniqueness than the perception of others as being similar to oneself. Individuals with high need for uniqueness exhibited greater asymmetry than did individuals with low need. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献
