Anxious attachment as an antecedent of people's aversion towards pattern deviancy

Research suggests that people's aversion towards pattern deviancy—distortions of repeated forms or models—contributes to social phenomena, such as prejudice. Yet, the factors motivating pattern deviancy aversion remain unclear. Potentially, anxious attachment, as it entails hypervigilant detection of and reactivity to social inconsistency and unreliability, heightens pattern deviancy aversion. In Studies 1 (N = 137) and 2 (N = 102), anxious but not avoidant attachment predicted aversion towards broken patterns of geometric shapes. In Studies 3 (N = 310) and 4 (N = 470), experimentally inducing anxious versus avoidant and secure attachment (Study 3), and versus a neutral prime (Study 4), heightened pattern deviancy aversion. Controlling for participants’ aversion towards unbroken patterns, novel objects, and negative stimuli did not change these results. Our findings demonstrate that anxious attachment is one antecedent of pattern deviancy aversion, and suggest that pattern deviancy aversion may underlie links between anxious attachment and certain social phenomena.     

乳腺癌的现代与传统治疗模式的比较分析与思考

乳腺癌是女性最常见的恶性肿瘤之一,现代治疗模式已经广泛应用于临床。近年来,随着循证医学和基因相关技术及生物信息技术的不断发展,乳腺癌治疗方法得到不断改进,但远没有达到系统化、个体化、最优化的治疗目的。因此,现有的治疗模式值得我们去深思,并从哲学意义上探索更为完善的治疗模式。     

Object Recognition: Insights From Advances in fMRI Methods

ABSTRACT— Recent advancements in imaging methods and analysis approaches have provided important insights about the neural bases of object recognition. We address the potential limitations of standard functional magnetic resonance imaging (fMRI) and discuss methodological advancements, including fMRI-adaptation, pattern analyses, and high-resolution fMRI, that may be more appropriate for studying object and face representations. fMRI-adaptation and high-resolution fMRI measure responses of neural subpopulations within standard fMRI voxels, and pattern analyses examine the information in the distributed activations across voxels, which may differ from the mean response across these voxels. These methods have provided evidence for a multitude of representations across the human ventral stream that provide empirical constraints for cognitive theories of recognition.

在新生儿缺氧缺血性脑病的诊疗中,乃至儿科疾病的防治中,应注重调节好矛盾的两方面,理论与实践的结合.医患双方处理好知情同意,避免诊疗中的过度医疗,对于建立积极主动的、和谐信任的医患互动模式非常重要.这也体现了双方对新生命的最大的珍惜和尊重.     

Compensatory Control: Achieving Order Through the Mind, Our Institutions, and the Heavens

ABSTRACT— We propose that people protect the belief in a controlled, nonrandom world by imbuing their social, physical, and metaphysical environments with order and structure when their sense of personal control is threatened. We demonstrate that when personal control is threatened, people can preserve a sense of order by (a) perceiving patterns in noise or adhering to superstitions and conspiracies, (b) defending the legitimacy of the sociopolitical institutions that offer control, or (c) believing in an interventionist God. We also present evidence that these processes of compensatory control help people cope with the anxiety and discomfort that lacking personal control fuels, that it is lack of personal control specifically and not general threat or negativity that drives these processes, and that these various forms of compensatory control are ultimately substitutable for one another. Our model of compensatory control offers insight into a wide variety of phenomena, from prejudice to the idiosyncratic rituals of professional athletes to societal rituals around weddings, graduations, and funerals.     

Tatsuoka 矩阵理论的修正

K .K.Tatsuoka和她同事开发的规则空间模型（RSM）是一种在国内外有较大影响的认知诊断模型,但是Tatsuoka的RSM中 矩阵理论存在缺陷和错误,这些失误使得RSM中用布尔描述函数（BDF）计算被试理想项目反应模式（IRP）的方法缺乏理论依据。这里揭示了Tatsuoka的 矩阵理论的缺陷和错误并引进既不使用BDF又便于应用的计算IRP的方法;接着还介绍一种由可达阵计算简化 阵的方法,该方法显示了可达阵在构造认知诊断测验的重要性。这些结果对丰富 矩阵理论及正确使用RSM进行认知诊断有一定的意义     

多目标追踪任务中不同运动方式非目标的抑制机制

采用多目标追踪范式结合点探测技术的方法, 考察视觉系统对不同运动方式(静止和规则运动)非目标的抑制机制。实验一将部分非目标设置为静止, 考察静止非目标的抑制机制; 实验二将部分非目标设置为规则运动, 以提高任务难度, 考察规则运动非目标的抑制机制。结果发现: (1) 实验一中静止非目标受到抑制, 抑制量与运动非目标没有差异; (2) 实验二中规则运动非目标受到抑制, 抑制量显著小于随机运动非目标; (3)综合两实验发现, 随着任务难度的提高, 只有随机运动非目标的抑制量显著增加, 而静止非目标与规则运动非目标的抑制量差异不显著。最后, 就视觉系统对不同运动方式非目标的抑制机制进行了讨论。     

大学生人际关系质量的影响因素研究

采用Rosellberg自尊量表、EMBU、大学生价值观问卷、自编"大学生人际关系主观因素问卷"及"人际关系质量量表"为工具,对1,137名本科生进行调查,以探讨大学生自尊、价值观、父母教养方式及人际关系的主观因素与大学生人际关系质量的关系.结果表明,父母教养方式、价值观与自尊对人际关系质量的直接效应很低,它们对人际关系质量的影响要以人际关系的主观因素为中介.因此,要构建大学生和谐人际关系,应特别重视影响其人际关系质量的主观因素教育.     

3～5岁儿童模式认知能力发展的研究

选取北京市10所幼儿园的249名3～5岁儿童为被试,采用概括抽象程度不同的任务对儿童的模式复制和扩展能力进行个别测查。结果表明:(1)儿童早期模式认知能力发展的年龄主效应显著,性别主效应显著,年龄与性别的交互作用显著。(2)儿童模式复制能力在3 5～4 5岁之间发展较为迅速,模式扩展能力在4～5岁之间发展较为迅速。(3)儿童的模式复制能力无显著性别差异,但女孩的模式扩展能力显著高于男孩。(4)儿童的模式复制能力显著高于模式扩展能力,随着年龄的增长它们之间的差距有减小的趋势。(5)随着年龄的增长,儿童在模式复制和模式扩展任务中所犯错误水平在下降。     

Synergistic influences of sensory and central stimuli on non-voluntary rhythmic arm movements

In recent years, neuromodulation of the cervical spinal circuitry has become an area of interest for investigating rhythmogenesis of the human spinal cord and interaction between cervical and lumbosacral circuitries, given the involvement of rhythmic arm muscle activity in many locomotor tasks. We have previously shown that arm muscle vibrostimulation can elicit non-voluntary upper limb oscillations in unloading body conditions. Here we investigated the excitability of the cervical spinal circuitry by applying different peripheral and central stimuli in healthy humans. The rationale for applying combined stimuli is that the efficiency of only one stimulus is generally limited. We found that low-intensity electrical stimulation of the superficial arm median nerve can evoke rhythmic arm movements. Furthermore, the movements were enhanced by additional peripheral stimuli (e.g., arm muscle vibration, head turns or passive rhythmic leg movements). Finally, low-frequency transcranial magnetic stimulation of the motor cortex significantly facilitated rhythmogenesis. The findings are discussed in the general framework of a brain-spinal interface for developing adaptive central pattern generator-modulating therapies.
