自我控制的能量模型:证据、质疑和展望

自我控制的能量模型是解释自我控制的一个重要理论模型。该模型认为,所有的自我控制行为依赖一种共同且有限的能量,执行自我控制会消耗这种能量,导致自我损耗效应的产生,但能量也可以通过一些方法得以恢复和提升。该模型得到大量行为和生理层面研究的支持,但也有研究者从疲劳、情绪、动机、血糖指标、时间知觉等方面提出质疑。未来研究可从自我能量的性质、总量等角度进一步完善能量模型,同时结合我国文化探讨理想、信念、价值观对提升我国国民意志力的作用。     

儿童歧视知觉模型述评

Brown和Bigler提出了儿童歧视知觉模型,分析了歧视知觉的三个影响因素:认知因素、情景因素和个体差异因素,每个因素都包含了多个影响儿童歧视知觉的子因素。该模型展示了这些因素影响儿童歧视知觉的机制。完善该模型需要探讨其与信息加工理论、发展群际理论、主观群体动力学模型的兼容性。歧视知觉的类型需要进一步细化,因此在综合主观群体动力学模型和发展模型的基础上提出了歧视知觉的分类方案。未来研究还要进一步探讨情绪、文化以及年龄因素对儿童歧视知觉的影响,并探讨该模型对歧视干预的意义。     

Quand le genre s’en mêle : quelle conciliation entre vie professionnelle et vie privée ?

Declarations of conciliation between private life and professional life based on three factors (sex, gender and positions) are studied in this paper. Our goals were (i) to show that conciliation between the different life spheres need to be considered both in terms of conflict and of life enrichment; (ii) and to demonstrate that the gender variable has combined effects with sex variables, as well as with positions variables, over the perception of work in relation to family interferences in terms of nature (conflict/enrichment), intensity and direction (family over work versus work over family). The study, conducted with 240 employees of low or high professional positions, based on SWING and BSRI scales, shows the moderating effect of gender on the perceptions of conciliation, whether enriching or conflicting. Our results also allow us to conclude that congruent adjustment (masculine domination) of the levels of our three factors constitute a protecting factor for employees, while an incongruent adjustment can constitute a risk factor, this being especially verified for women.     

男同性恋的身体意象：特点与理论分析

对男同性恋身体意象的研究有近30年的历史。男同性恋比男异性恋更容易出现负面身体意象、身体不满意和进食障碍等。男同性恋追求瘦而有肌肉的理想身体。针对这些特点, 研究者提出一些理论假设进行解释, 包括性客观化理论、内化同性恋污名、性别角色假设、进化心理学假设和AIDS/HIV假设等。未来研究要进行整合的和多样化的研究取向, 方法上采用以网络调查为主的定量研究和以现象学分析为主的定性研究。最后, 国内研究要更注重文化特异性。     

音乐经验对言语加工能力的促进作用

以初中二年级的学生为考察对象,探讨了音乐经验对不同层次的言语加工能力的促进作用,发现：在声音信号的加工层面,音乐经验对音高和时长信息感知能力的发展都有积极的促进作用;在语音意识层面,音乐经验的促进作用只局限于声调意识;在言语记忆方面,音乐经验可以促进言语材料在长时记忆中的保持。     

Knowledge,beliefs, peer norms,and past behaviors as correlates of risky sexual behaviors among college students

Abstract

HIV/AIDS knowledge, age at onset of sexual activity, perceptions of personal risk and peer norms were explored as correlates for risky sexual behaviors among college students. Ninety-nine male and 185 female college students completed a 66-item questionnaire. A majority reported being sexually active with most in mutually monogamous relationships or not currently in a sexual relationship. Multiple regression correlation analyses showed knowledge about HIV/AIDS to be very high but that this knowledge did not independently relate to the extent of risky behaviors. Perceptions of risk were positively related to number of partners and single-time partners but not condom usage. In contrast to previous studies, perceived peer norms did not independently relate to behaviors. Instead, age at first intercourse was found to have substantial overlap with current perceptions, attitudes, and likelihood for engaging in risky behaviors. The necessity for including previous behaviors in analyses of the impact of attitudes and perceived norms on behavioral intentions is discussed.     

Life values and mental health: A longitudinal study comparing chronically ill women to women without chronic disease

We tested the hypothesis that among women who are chronically ill, a re-ordering of life values maintains mental health. A community-based prospective longitudinal study was conducted in which data were obtained from 601 women in 1986, when the women were with mean age 42 and again in 2003, when the women were with mean age 58. There was a significant change in life values as women aged with more change among women with chronic disease (n = 476) than those without chronic disease (n = 125). Increased valuation of intrinsic life values (health and love) and decreased valuation of extrinsic life values (power, fame and attractiveness) were associated with subsequent better mental health for women with chronic disease, but not for those without chronic disease.     

What do pre-adolescents and adolescents understand about HIV/AIDS?

Abstract

Pre-adolescents and adolescents (N= 80, aged 10, 12, 15, and 18 years) were tested on their knowledge of HIV/AIDS. Knowledge was assessed using a self-report questionnaire (examining levels of factual knowledge) and a semi-structured interview (examining cognitive developmental levels of understanding). Examination of the developmental shifts in understanding of HIV/AIDS revealed an increase in conceptual complexity on causal and prevention dimensions. The main conceptual changes included a shift from single cause to multiple cause solutions and a shift from identifying surface or immediate features to implicating less salient features. Additionally, with age, concepts about HIV/AIDS were increasingly organised around internal, physiological principles. Questionnaire responses yielded significant age-related increases in knowledge. Level of knowledge, as measured by the questionnaire, was higher than that assessed by the interview for the three youngest age groups. Thus, factual information acquired about HIV/AIDS is not automatically accompanied by understanding. In light of these findings the past conclusion that adolescents have high levels of knowledge of HIV/AIDS is questioned.     

Binge-Drinking: A Test of the Role of Group Norms in the Theory of Planned Behaviour

A study was undertaken to assess the utility of the theory of planned behaviour in the prediction of students' binge-drinking. Additionally, a perspective was utilised to address the usually weak contribution of subjective norms in predicting behavioural intentions. Respondents were 289 undergraduate students. The study employed a longitudinal design, with the predictors of performing the behaviour under consideration assessed prior to the measure of reported behaviour. Support was found for the application of the theory of planned behaviour to binge-drinking. A reconceptualisation of norms in the theory of planned behaviour, from a social identity theory/self-categorization theory perspective, was also supported; consistent with expectations, the norms of a behaviourally relevant reference group predicted intentions to binge-drink, especially for participants who identified strongly with the reference group. The results are discussed in relation to measures which may help to reduce the incidence of binge-drinking by university students.
