Do Inferences about Age Differences in Emotional Experience Depend on the Parameters Analyzed?

Age differences in emotional experience are assessed through self-report scales or questionnaires referring to a specific period of varying length, and examining different parameters of emotional response. A recent meta-analysis suggests that the type of instrument and parameter used could account for some of the inconsistencies in the results. The present study shows comparisons between emotional experience in samples of younger (N = 120, aged 20–27) and older (N = 103, aged 55–75) participants. An Emotional Self-Monitoring record was administered every day for a week. The results show that emotional expression was highly stable over time. However, they also show that some theoretical assumptions about individual age differences in emotional experience and age depend on the parameters on which the analysis is based (occurrence, frequency and intensity, and emotional balance).     

摩梭人亲属词的概念结构

采用自由分类法探讨了摩梭人亲属词的概念结构。结果表明：(1)摩梭人亲属词的概念结构有两个维度：“亲属的亲密程度”和“辈分大小”。这与汉族和纳西族亲属词的概念结构既相似, 又存在差异。摩梭人亲属词分类的特点反映了独特的母系家庭和婚姻制度。(2)舅权和父权在摩梭人的亲属关系中正在经历着变化。作者对“摩梭母系制是原始母系制的‘活化石’”的观点提出了质疑。     

感觉寻求对工读生毒品使用的影响：有中介的调节效应

以523名工读生为调查对象,考察工读生毒品使用特点,并在控制相关人口学变量后,探讨感觉寻求、压力性生活事件、结交不良同伴与工读生毒品使用的关系。结果显示：（1）工读生的毒品使用行为严重,34.2%的工读生曾使用过毒品,毒品使用呈现低龄化、以吸食新型毒品为主的趋势。（2）工读生的感觉寻求是毒品使用的风险因素。（3）压力性生活事件对感觉寻求与毒品使用之间的关系具有风险增强的调节效应。（4）这种调节效应以结交不良同伴为中介变量。因此,感觉寻求对工读生毒品使用的影响是有中介的调节效应。研究结果对青少年毒品使用的预防和干预有重要的理论价值和参考价值。     

自尊与心理性应激反应的关系：社会认可需求的中介作用

国外研究者认为高自尊个体的内控性高,因此其在心理性应激情境中的反应不那么强烈,而国内研究者从集体文化(中国)考虑,则认为高自尊个体的社会认可需求较高,因此在心理性应激情境中的反应更强烈.本研究采用特里尔社会应激测试作为应激情境,采集41名中国大学生被试在这一情境下的客观参数(心率)作为心理性应激反应的指标,通过问卷测量被试的自尊水平、内控性水平和社会认可需求水平,考察自尊影响心理性应激反应的机制.结果发现被试的自尊水平与应激情境下的心率呈正相关,并且社会认可需求在自尊与心理性应激的关系中起着显著的中介作用.本文从文化差异角度提出自尊预测心理性应激反应的模型可能需要在不同文化背景下来分别探讨.     

声符和义符在形声字语音、语义提取中的作用

采用眼动技术记录汉语阅读者在形声字的语音、语义提取中对声符和义符的注意规律, 考察形声字部件的位置、功能和正字法意识对汉字认知的影响。结果表明：(1)在汉字的视觉加工中, 阅读者对部件空间位置的注意加工优势受到声旁位置的调节。对左形右声结构的汉字, 被试更多地注意字的右边, 对右形左声结构的汉字, 被试更多地注意字的左边; (2)在汉语阅读者的正字法规则中, 存在着“左侧释义、右侧释音”的部件的位置-功能联结。(3)在通达形声字的语音、语义的过程中, 与义符相比, 声符具有注意资源的优势, 这种优势在语音提取任务中更加明显：声符无需依赖义符的信息便可以相对独立地激活整字的语音, 但声符需要义符的配合才能够提取整字的语义。     

成瘾人群跨期选择的神经机制及干预方法

成瘾可分为物质成瘾和行为成瘾, 两类成瘾人群在跨期选择上都表现出高时间折扣率的缺陷, 但也有各自的特异性特征。成瘾人群跨期选择缺陷的神经基础主要集中在评估网络(腹内侧前额叶、纹状体、后扣带皮层等)、认知控制网络(前额叶皮层、前扣带皮层等)和预期想象网络(海马、杏仁核等); 可利用心理训练来改善成瘾人群跨期选择缺陷, 其干预方法包括工作记忆训练、预期想象训练、金钱管理指导等。未来研究应该从成瘾者跨期选择缺陷的认知机制、3个神经网络系统的交互作用机理、行为遗传学以及开发有效的干预方法等方面展开大量研究。     

基础认知与社会认知中内隐过程及其脑机制*

认知过程及其脑机制是心理学研究的重要内容。社会认知是人们在社会生活中对他人行为的意图及情感的认识,是人际互动的重要方面,具有深刻的理论和实践意义。本文全面深入地对社会认知和基础认知中自动加工过程进行了研究综述,对基础认知与社会认知的研究方式进行了比较。自动加工过程是社会认知和基础认知中都存在的重要过程,从脑机制研究角度,相关的电生理学指标(如N400等)都可以作为研究的指标来考察社会认知中的自动加工过程。本文从社会认知与基础认知的比较入手,介绍了各种领域的研究方法,特别是事件相关电位技术等认知神经科学研究方法。     

Phonological mediation in visual masked priming: evidence from phonotactic repair

In a series of 4 experiments, the authors show that phonological repair mechanisms, known to operate in the auditory modality, are directly translated in the visual modality. This holds with the provision that printed stimuli are presented for a very brief duration and that the effect of phonological repair is tested after a delay of some 100 ms has elapsed after that presentation. The case of phonological repair chosen to exemplify the parallelism between print and speech is the prosthesis of /e/ in utterances beginning with /s/ followed by a consonant in Spanish. Native speakers of Spanish hear a prothetic /e/ in auditorily presented pseudowords such as special (/speojal/, derived from "especial") as well as stuto (/stuto/, derived from "astuto"). It is shown here that they also hear that same vowel /e/ when presented with the printed pseudowords "special" and "stuto." This finding of a phonological repair effect in print has implications for the issue of phonological activation from print, as well as for the prelexical locus and mandatory nature of phonological repair mechanisms in general.     

The social-cognitive model of achievement motivation in physical education

Our objective in this study was to test the new social-cognitive model of achievement motivation in a physical education setting. Research was conducted on a sample of 895 physical education students, ages 12 to 16 years. We measured perception of the motivational climate conveyed by the teacher, implicit beliefs of ability, perceived competence, 2 x 2 achievement goals and self-determined motivation. We carried out structural equation modeling to analyse the relationships among variables. Results showed that task climate positively predicted incremental belief, whereas ego climate positively predicted entity belief. Both climates positively predicted perceived competence. Incremental belief positively predicted mastery-approach goals, performance-approach goals and avoidance goals, whereas entity belief positively predicted performance-approach goals and avoidance goals. Perceived competence positively predicted mastery-approach and performance-approach goals. Mastery-approach goal positively predicted self-determined motivation, whereas performance-approach goal and avoidance goals negatively predicted self-determined motivation.     

Links between sex-related expectations about alcohol, heavy episodic drinking and sexual risk among young men in a shantytown in Lima, Peru

CONTEXT: Alcohol use is frequently identified as a contributor to risky sexual behaviors; however, research results are mixed. Given the conflicting evidence, researchers have focused on other factors, such as expectations about alcohol's effects that might help explain the relationship of alcohol use and risky sexual behaviors. METHODS: Cross-sectional data from 312 sexually experienced males aged 18-30 in a shantytown in Lima, Peru, were used in logistic regression models to identify associations of heavy episodic drinking and sex-related expectations about alcohol with sexual risk behaviors. RESULTS: Heavy episodic drinking was associated with having had two or more sexual partners and having had sex with a casual partner in the past year (odds ratios, 2.8 and 2.5, respectively). After controlling for alcohol consumption, sex-related expectations about alcohol were associated with these high-risk sexual behaviors, as well as with not using a condom at last sex (1.2) and not using a condom at last sex with a casual partner (1.3). CONCLUSION: Beliefs about the effect of alcohol on sexual performance could help explain links between alcohol consumption and risky sexual behavior not completely accounted for by the pharmacological effects of alcohol.
