高效率学习是现代社会发展的需要,也是适应信息量急增的社会变革需要的必然选择。从教育心理学的视角研究策略型学习者,对其高效率学习心理,特别是高效率学习认知心理结构及其运行机制进行研究,有助于教育理论与实践工作者准确把握这类特殊教育对象的心理特点与规律,为开展策略型学习者教育提供了心理学依据。     

Influence of Hostile Media Perception on Willingness to Engage in Discursive Activities: An Examination of Mediating Role of Media Indignation

This study examines the mediating role of media indignation, a set of negative emotional reactions to media coverage perceived to have partisan bias, between hostile media perception (HMP) and its consequences in behavioral willingness, more specifically, willingness to engage in discursive activities. It is examined together with a cognitive pathway through individuals' inference on opinion climate. Data from a web-based survey of university students (N = 696) on three controversial issues were analyzed. Findings showed that the degree of perceived partisan bias in mainstream media coverage on an issue was positively related to the intensity of media indignation and levels of incongruity between one's own opinion and perceived majority opinion. Media indignation in turn had a significant and positive effect on willingness to engage in discursive activities across all three issues, mediating the effect of HMP on behavioral willingness, whereas self-majority opinion incongruity did not. Theoretical implications of the findings are discussed.     

甲状腺癌的诊治原则

甲状腺癌是内分泌系统最常见的恶性肿瘤,它的发病率正逐年增加,其诊断方法包括体格检查、超声检查、细针穿刺、影像学检查及实验室检查等,甲状腺癌的治疗以外科手术为主,对较晚期或远处转移的患者可行综合治疗(I131,放疗,化疗)。总之,甲状腺癌经合理治疗,可获得较好的预后。     

早期宫颈癌术式选择的比较研究

根治性子宫切除术与保留生育功能的根治性宫颈切除术均可用于早期宫颈癌患者的手术治疗。根据生物-心理-社会医学模式的要求,本文采用比较治疗学的方法,对这两种手术方式,从适应证、手术方式、并发症、疗效等方面进行比较,为宫颈癌临床科学决策提供借鉴。     

以杀止杀,岂乐之哉!——试析葛洪的刑治思想

本文尝试通过梳理《抱朴子外篇.用刑》所展现的"刑治"思想,来对葛洪的思想体系概貌作一全面的把握。葛洪将刑罚视为"国之神器",对刑罚的必然性与必要性作了充分论证。葛洪的刑治思想是秦汉黄老道家涵容法家思想的延续与发展,也是其自身思想体系不可分割的组成部分,对于理解和把握道教的社会政治思想有着重要的价值和意义。     

阿伦·奈斯的深层生态学思想

阿伦·奈斯开创了当代环境哲学研究的一个全新领域。他不仅为深层生态学建立了较为完整的框架体系,而且也为深层生态学的发展提供了重要的理论基础(生态智慧T)。对于深层生态学的研究者来说,不系统地认识奈斯的思想就无法深刻地理解深层生态学。     

领导者的希望和自我效能感对其主观幸福感的影响

该研究采用问卷调查法,检验领导者的希望和自我效能感对其主观幸福感的影响作用。通过对来自重庆市各县、市、区政府机关、公检法和事业行政单位的237名领导者进行调查,将搜集的数据进行层次回归分析、中介效应检验和优势分析,结果显示：希望和自我效能感是领导者的主观幸福感的显著正向预测变量;自我效能感在领导者的希望与其主观幸福感之间有显著的完全中介作用;增强领导者的希望与自我效能感水平对提升领导者的主观幸福感有显著的促进作用。     

Impulsivity Moderates Promotive Environmental Influences on Adolescent Delinquency: A Comparison Across Family, School, and Neighborhood Contexts

The present study examined moderating effects of impulsivity on the relationships between promotive factors from family (family warmth, parental knowledge), school (school connectedness), and neighborhood (neighborhood cohesion) contexts with delinquency using data collected from N?=?2,978 sixth to eighth graders from 16 schools surrounding a major city in the Midwestern United States. More than half of the respondents were non-Caucasian (M _age ?=?12.48; 41.0 % male). Multilevel modeling analyses were conducted to take into account the clustering of the participants within schools. Impulsivity was positively associated with adolescent delinquency. Additionally, family warmth, parental knowledge, and school connectedness, but not neighborhood cohesion, were independently and inversely related to adolescent delinquency. Finally, impulsivity moderated relationships between family warmth and parental knowledge with delinquency but not relationships between school attachment and neighborhood cohesion with delinquency. Specifically, the negative relationship between family warmth and delinquency was significant for adolescents with high levels of, but not for those with below-average levels of, impulsivity. In addition, parental knowledge had a stronger association with decreased levels of delinquency for adolescents reporting higher levels of impulsivity. The moderating effects of impulsivity did not differ for males and females or for minority and non-minority participants. Findings indicate that impulsivity may have greater impact on adolescents’ susceptibility to positive family influences than on their susceptibility to promotive factors from school or neighborhood contexts. Implications for future research and practice are discussed.     

Improving computer skill training: behavior modeling, symbolic mental rehearsal, and the role of knowledge structures

Effective computer skill training is vital to organizational productivity. Two experiments (N = 288) demonstrated that the behavior modeling approach to computer skill training could be substantially improved by incorporating symbolic mental rehearsal (SMR). SMR is a specific form of mental rehearsal that establishes a cognitive link between visual images and symbolic memory codes. As theorized, the significant effects of SMR on declarative knowledge and task performance were shown to be fully mediated by changes in trainees' knowledge structures. The mediational role of knowledge structures is expected to generalize to other training interventions and cognitive skill domains. Our findings have the immediate implications that practitioners should use SMR for improving the effectiveness of computer skill training.     

Electrophysiological difference between the representations of causal judgment and associative judgment in semantic memory

Causally related concepts like “virus” and “epidemic” and general associatively related concepts like “ring” and “emerald” are represented and accessed separately. The Evoked Response Potential (ERP) procedure was used to examine the representations of causal judgment and associative judgment in semantic memory. Participants were required to remember a task cue (causal or associative) presented at the beginning of each trial, and assess whether the relationship between subsequently presented words matched the initial task cue. The ERP data showed that an N400 effect (250–450 ms) was more negative for unrelated words than for all related words. Furthermore, the N400 effect elicited by causal relations was more positive than for associative relations in causal cue condition, whereas no significant difference was found in the associative cue condition. The centrally distributed late ERP component (650–750 ms) elicited by the causal cue condition was more positive than for the associative cue condition. These results suggested that the processing of causal judgment and associative judgment in semantic memory recruited different degrees of attentional and executive resources.
