本研究采用数字STROOP、局部-整体图形转换和色点位置刷新三种研究范式检测了40名攻击性初中生的抑制控制、任务转换和信息刷新三种执行功能的特点。研究结果表明,攻击性初中生的抑制控制能力、任务转换能力和信息刷新能力均差于非攻击性初中生。外部攻击型初中生的抑制控制能力、任务转换能力和信息刷新能力均差于非攻击性初中生。而关系攻击型初中生与非攻击性初中生和外部攻击型初中生在执行功能的三种成分上均不存在显著差异,其执行功能水平可能介于非攻击性初中生和外部攻击初中生之间。 相似文献

"组织起来"像一条金线贯穿于建国后的农业合作化运动中,也渗透在毛泽东的农业合作思想中.作为毛泽东农业合作思想有力的通俗表达方式,"组织起来"蕴含着丰富的内涵,也有着背后的政治逻辑."组织起来"在一定程度上促进了农田水利建设,发展了农业生产,支援了工业化建设,但是,基于那个时代的局限,经验的有限与实践的复杂,毛泽东农业合作化思想在实践过程中凸显出理论、利益及制度方面的困窘,从而不可避免地在农业合作实践中遭受挫折和失败.今天,面对亿万分散的一家一户的小农经济,2010年中央一号文件进一步提出"着力提高农业生产经营组织化程度",毛泽东"组织起来"的农业合作思想再次呈现其广阔的前景和张力. 相似文献

Self-regulatory behavior in early childhood is an important characteristic that has considerable implications for the development of adaptive and maladaptive functioning. The present study investigated the relations between a functional polymorphism in the upstream region of monoamine oxidase A gene (MAOA) and self-regulatory behavior in a sample of Chinese infants at 6 months of age. Self-regulation was assessed by observing infants' behavior of orienting visual attention away from a threatening event in the laboratory situation. The results indicated that regulatory behavior was associated with the functional MAOA gene polymorphism in girls, but not boys. Girls with 4/4 genotypes displayed significantly higher regulation than girls with 3/3 and 3/4 genotypes. The present study provided evidence for gender differences on the role of MAOA gene polymorphism in socioemotional functioning in the early years. 相似文献

Episodic memory was assessed using Virtual Reality (VR). Forty-four (44) subjects visualized a target virtual apartment containing specific objects in each room. Then they visualized a second virtual apartment comprised of specific objects and objects shared by the two apartments. Subjects navigated in the virtual apartments in one of the following two conditions: active and passive. Four main episodic memory components were scored from the VR exposures: (1) learning effect; (2) active forgetting effect; (3) strategies at encoding and at retrieval; and (4) false recognitions (FRs). The effect of navigation mode (active vs. passive) on each memory component was examined. Active subjects had better learning and retrieval (recognition hits) performances compared to passive subjects. A beneficial effect of active navigation was also observed on the source-based FR rates. Active subjects made fewer source-based FRs compared to passive subjects. These overall results for the effect of active navigation are discussed in terms of the distinction between item-specific and relational processing. 相似文献

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
