婴儿自我认知发生再探

文章在纵向研究基础上,通过横向设计,采用实验室实验、情境观察和母亲访谈相结合的方法考察213名14～24个月婴儿自我认知(视觉和言语方面)的发生.结果表明:1)婴儿自我认知在15～24个月间发生,自我认知能力逐渐出现,随年龄增长而发展.2)视觉自我认知一般发生于第17个月;视觉自我认知无显著的性别差异.3)言语自我认知一般发生于第21个月;男婴言语自我认知获得时间晚于女婴,但在获得言语自我认知后,婴儿言语自我认知无性别差异.4)视觉自我认知对言语自我认知有正向预测作用,视觉自我认知发生早的婴儿,言语自我认知发生的也早.     

不同视角条件下条件推理任务和选择任务的反应模式

在不同视角条件下,要求被试先后完成选择任务和条件推理任务,考察被试在不同视角条件下对两种任务的反应模式。实验结果表明,提供强制情境下对立角色违反规则的信息时,两种任务的反应模式没有明显的关联;提供非强制情境下的反例信息时,两种任务的反应模式出现分离趋势;当对规则的语义关系进行充分非必要或必要非充分关系的解释时,两者又趋于一致。分析表明,被试采用多种策略完成选择任务,而是否采用条件推理的逻辑取决于特定情境能否激活这种逻辑。     

寺庙生态文化与可持续发展简论——兼论新津老君山旅游开发

寺庙生态文化由自然生态与人文生态两个部分构成.自然生态是指寺庙与其所在自然环境构成的一种生态关系,复有"自然地理取向"与"宗教地理取向"两种形式,从形而下与形而上两方面将寺庙与尘世拉开距离.人文生态是指寺庙与其信众并社会构成的一种生态关系,借助仪式法会、观光朝圣等等活动而在神圣与凡俗之间显现活力,寺庙生态文化的基本原则是寺庙旅游开发恪守的底线.遗憾的是,如老君山等寺庙文化、宗教文化旅游开发并未恪守此一底线.     

与用客体表征连续性解释OSPBs效应的商榷

Mitroff等人的研究发现了OSPBs效应量反映的客体运动方式与主观报告结果相分离的现象,并以两可刺激情景或实体性原则违背假设对该现象作了解释。本文以3个实验与其研究进行了商榷。结果表明,两可刺激情景与实体性违背均不能解释上述分离现象(实验1);其实验范式中混入了距离因素(实验2与实验3)和方位朝向因素(实验1)。基于本研究的结果,笔者认为Mitroff等人的OSPBs效应是由距离效应和方位倾斜效应所致,即可能主要反映了基于空间的选择性注意的影响,而不能以客体表征连续性加以解释。     

公共选择中的公正与效率——公共支出隐含的一个悖论

公共支出的决定程序、运用与来源以及内在的价值取向上,都存在着公正与效率的矛盾,这无疑会影响到公共支出对经济增长的拉动作用.若要兼顾公正与效率以及调和公共支出内在的逻辑矛盾,便需要确定更有效的标准和选择合适的规则,降低交易成本和信息不时称的程度,以更透明的程序和更兼顾社会民众的方式,实现由功能财政向公共财政和民主财政的转变,以此提高积极财政政策的作用效率.     

Urban residents' subtle prejudice towards rural‐to‐urban migrants in China: The role of socioeconomic status and adaptation styles

The household registration system (Hukou) implemented by the Chinese government divides the Chinese society into two groups: urban residents and rural residents. Since the 1980s, millions of rural residents have migrated to cities without official permission. In this paper, we investigate urban residents' subtle prejudice towards rural‐to‐urban migrants. Specifically, the impacts of urban residents' socioeconomic status (SES) and their perception of migrants' adaptation styles are examined. A sample including 457 Chinese urban residents is taken from four cities in China. Educational and occupational levels are used to indicate urban residents' SES. Four adaptation styles (integration, assimilation, separation and marginalization) are manipulated by using vignettes. The results show that SES has a negative impact on urban residents' subtle prejudice. This link is further moderated by urban residents' perceptions of migrants' adaptations: the negative effect of SES on subtle prejudice holds only under a perception of integration or assimilation and disappears under a perception of separation or marginalization.

What subjective experiences determine the perception of falling asleep during sleep onset period?

Sleep onset is associated with marked changes in behavioral, physiological, and subjective phenomena. In daily life though subjective experience is the main criterion in terms of which we identify it. But very few studies have focused on these experiences. This study seeks to identify the subjective variables that reflect sleep onset. Twenty young subjects took an afternoon nap in the laboratory while polysomnographic recordings were made. They were awakened four times in order to assess subjective experiences that correlate with the (1) appearance of slow eye movement, (2) initiation of stage 1 sleep, (3) initiation of stage 2 sleep, and (4) 5 min after the start of stage 2 sleep. A logistic regression identified control over and logic of thought as the two variables that predict the perception of having fallen asleep. For sleep perception, these two variables accurately classified 91.7% of the cases; for the waking state, 84.1%.     

Bias in longitudinal data analysis with missing data using typical linear mixed‐effects modelling and pattern‐mixture approach: An analytical illustration

We analytically derive the fixed‐effects estimates in unconditional linear growth curve models by typical linear mixed‐effects modelling (TLME) and by a pattern‐mixture (PM) approach with random‐slope‐dependent two‐missing‐pattern missing not at random (MNAR) longitudinal data. Results showed that when the missingness mechanism is random‐slope‐dependent MNAR, TLME estimates of both the mean intercept and mean slope are biased because of incorrect weights used in the estimation. More specifically, the estimate of the mean slope is biased towards the mean slope for completers, whereas the estimate of the mean intercept is biased towards the opposite direction as compared to the estimate of the mean slope. We also discuss why the PM approach can provide unbiased fixed‐effects estimates for random‐coefficients‐dependent MNAR data but does not work well for missing at random or outcome‐dependent MNAR data. A small simulation study was conducted to illustrate the results and to compare results from TLME and PM. Results from an empirical data analysis showed that the conceptual finding can be generalized to other real conditions even when some assumptions for the analytical derivation cannot be met. Implications from the analytical and empirical results were discussed and sensitivity analysis was suggested for longitudinal data analysis with missing data.     

善心点亮创造力:内部动机和亲社会动机对创造力的影响

研究者普遍认为,个体的内部动机促进创造力,但这种观点受到了越来越多的挑战与质疑。最新的动机性信息加工理论认为,亲社会动机能使个体不仅关注新颖性,而且重视实用性,从而提高创造力。本研究采用2×2组间设计,操纵内部动机和亲社会动机,将被试随机分配到其中一种条件下完成一项创造任务。方差分析结果发现,内部动机和亲社会动机对创造力的影响存在交互作用,只有当亲社会动机高时,内部动机才显著提高创造力;内部动机和亲社会动机均高时,个体创造力最高。本研究证明了亲社会动机在创造过程中的重要性,为创造力研究提供了新的视角。
