This study compared psychological and behavioral responses in a take-some social dilemma with those in a give-some situation and suggested an explanation in terms of a dual process model. Participants facing the take-some dilemma exhibited a higher level of cooperation than those facing the give-some dilemma only in their first decision trial, and this effect was independent of our experimental manipulation of the information processing mode. Furthermore, once an experiential mode was induced, participants spent less time and experienced less conflict when making decisions in the take-some dilemma than in the give-some situations. The findings indicate that in social dilemmas the information processing mode has a stronger effect on psychological responses than on behavioral responses. 相似文献

Internet addiction among college students has become a serious problem in China. This pilot study involved the development of an online expert system named Healthy Online Self-helping Center (HOSC) as an intervention tool to help those who wish to reduce online usage. The study also explored the effectiveness of HOSC for college students' Internet addiction behavior. Participants (N?=?65) were recruited from a university in Beijing, and were randomly assigned to one of four conditions: using HOSC within a laboratory environment, using HOSC within a natural environment, using a noninteractive program, and a control group. All the participants were asked to answer questionnaires at the baseline and at the 1-month follow-up. The questionnaires included the participants' online hours per week, the legitimate ratio of Internet usage, online satisfaction, and the Young's Diagnostic Questionnaire. The results revealed that HOSC under both natural and laboratory environments could effectively reduce the participants' online hours per week as well as their Young's Diagnostic Questionnaire score, and improve online satisfaction at a 1-month follow-up. Participants using a noninteractive program also had similar results. The article concludes with a discussion of the limitations of the study, as well as the implications of the findings and future research directions. 相似文献

Several studies have demonstrated that as listeners hear sentences describing events in a scene, their eye movements anticipate upcoming linguistic items predicted by the unfolding relationship between scene and sentence. While this may reflect active prediction based on structural or contextual expectations, the influence of local thematic priming between words has not been fully examined. In Experiment 1, we presented verbs (e.g., arrest) in active (Subject–Verb–Object) sentences with displays containing verb-related patients (e.g., crook) and agents (e.g., policeman). We examined patient and agent fixations following the verb, after the agent role had been filled by another entity, but prior to bottom-up specification of the object. Participants were nearly as likely to fixate agents “anticipatorily” as patients, even though the agent role was already filled. However, the patient advantage suggested simultaneous influences of both local priming and active prediction. In Experiment 2, using passive sentences (Object–Verb–Subject), we found stronger, but still graded influences of role prediction when more time elapsed between verb and target, and more syntactic cues were available. We interpret anticipatory fixations as emerging from constraint-based processes that involve both non-predictive thematic priming and active prediction. 相似文献

高青陈庄铜器铭文与城址性质考 总被引:3,自引:1,他引:2
山东高青陈庄西周城址及墓地的发现对于西周考古与历史的研究意义重大。本文根据迄今所报道的资料,对两则铜器铭文做了解读,并对陈庄城址的性质做了推考。文章认为,陈庄墓地从西周早期成王开始延续到中期的昭穆时期,其间未曾中断,与城址的存续时间相吻合。陈庄城址规模较小,不大可能是西周齐国的都城,其属于齐国贵族封邑的可能性较大;而这个封邑,应该是豐。 相似文献
