Body image and personality: Associations between the Big Five Personality Factors,actual‐ideal weight discrepancy,and body appreciation

Studies have suggested associations between personality dimensions and body image constructs, but these have not been conclusively established. In two studies, we examined direct associations between the Big Five dimensions and two body image constructs, actual‐ideal weight discrepancy and body appreciation. In Study 1, 950 women completed measures of both body image constructs and a brief measure of the Big Five dimensions. In Study 2, 339 women completed measures of the body image constructs and a more reliable measure of the Big Five. Both studies showed that Neuroticism was significantly associated with actual‐ideal weight discrepancy (positively) and body appreciation (negatively) once the effects of body mass index and social status had been accounted for. These results are consistent with the suggestion that Neuroticism is a trait of public health significance requiring attention by body image scholars.     

On Living in an Unjust Society

ABSTRACT Can it be wrong to simply live in an unjust society? Four moral principles: group responsibility, unjust enrichment, a general duty to prevent injustice and the need to preserve one's moral integrity indicate that it might be. I explore the implications of each of these principles and conclude that while the possibility of doing good might counterbalance the threat to moral integrity, a person who continues to live in an unjust society should repudiate the injustice to avoid being held responsible for it and has a duty to compensate those deprived if he is unjustly enriched. Moreover, the general duty to prevent injustice bears more heavily on those who are closest to it.     

注意控制和短时存储对音位流畅性和语义流畅性的影响

工作记忆的中央执行系统具有注意控制和短时存储的功能。采用双任务范式,探讨了中央执行系统的注意控制和短时存储对言语流畅性的影响。实验1考察了中央执行系统的转换和抑制功能对音位流畅性和语义言语流畅性的影响。结果表明,中央执行系统的转换和抑制功能对两种言语流畅性的影响相当。实验2考察了中央执行系统的注意控制资源和短时存储资源对两种言语流畅性的影响。结果表明,语义流畅性更依赖于短时存储资源,音位流畅性更依赖于注意控制资源。研究还发现,被试完成语义流畅性任务的策略更易受概念系统的特性影响,完成音位流畅性任务的策略更易受语言的特点影响。在实验研究的基础上,作者提出了工作记忆影响言语流畅性的理论模型     

不同学习方式下归类不确定时的特征推理

采用学习-迁移模式, 探讨了同时学习和继时学习两种方式下归类不确定时的特征推理。共包括2个实验, 其中实验1探讨了固定学习轮次的情况, 实验2探讨了固定学习正确率的情况。实验结果表明：同时呈现类别要素的同时学习方式下, 被试习得序列式的单类别表征(原型表征), 在归类不确定时的特征推理中按照“单类的Bayesian规则”进行特征推理, 即P(j\F) =P(k\F)·P(j\k); 相继呈现类别要素的继时学习方式下, 被试习得并列式的多类别表征, 在归类不确定时的特征推理中按照“理性模型”进行推理, 即 P(j\F) =Σk P(k\F)·P(j\k)。     

初二学生知觉到的教师期望、自我价值感与目标取向的关系研究

以274名初中二年级学生为被试,采用验证性因素分析和多元回归方法对教师期望、自我价值感及目标取向的关系进行研究。结果表明:(1)人口统计学变量(性别和班别)对教师期望、自我价值感及目标取向有影响。(2)教师期望与自我价值感和目标取向相关显著:积极效应与自我价值感及目标取向的各维度呈显著正相关,消极效应与自我价值感及目标取向各维度呈显著负相关。(3)在控制了人口统计学变量后,教师期望与自我价值感仍对目标取向各维度具有较强的预测作用。(4)自我价值感在教师期望对目标取向各维度的影响上起到了中介作用。     

“动作-评价”效应:动作与认知的交互作用

"动作-评价"效应是具身认知理论的一个重要的支持性证据。早期研究表明,人们倾向于对积极刺激做"拉"反应而对消极刺激做"推"反应,进而在效价评定过程中表现出一种"动作-评价"效应。而随后一系列研究发现该效应的表现模式并非固定,并且该效应的发生不仅限于"推拉"动作。相应的,研究者也对这些现象做出了多种观点解释。进一步研究需继续深入探索"动作-评价"效应的本质及该效应的局限范围,以统合各种观点。     

心理理论和语言能力的关系

心理理论和语言能力的关系已日益引起研究者们的关注.文章综述了以非人灵长类动物、正常儿童和特殊人群为对象进行的有关心理理论和语言关系的研究,从比较和发展的角度进行了理论分析.提出一定的语言能力水平也许是通过心理理论测试的前提条件,但二者有着不同的发展规律,并表现为复杂的共存关系.
