视觉工作记忆的巩固加工：时程、模式及机制

在视觉工作记忆加工过程中, 对记忆项目的维持及操作需要将转瞬即逝的感觉输入转换为稳定的记忆表征, 这一加工过程被定义为视觉工作记忆巩固。鉴于巩固在视觉工作记忆中所起到的“门控”作用, 研究者们已经发展出多种研究范式对其可能涉及的运作机制进行探讨。然而, 在不同范式下所观察到的巩固时程存在较大差异, 其所遵循的巩固模式也尚不清晰。此外, 对于巩固所涉及的理论及神经机制亦存在不同的观点。通过对比不同范式的差异性及梳理各方的观点, 可以有效推动这些问题的解决。未来研究除了可以在多种范式下对巩固模式进行验证, 还可以探究注意在巩固中的作用, 以及项目熟悉性等因素会对巩固加工产生何种影响。     

The illusion of replacement in research into the development of thinking biases: the case of the conjunction fallacy

The conjunction fallacy is a violation of a very basic rule of probability. Interestingly, although committing the fallacy seems irrational, adults are no less susceptible to the fallacy than young children. In Experiment 1, by employing tasks where the conjunctive response option involved two non-representative items, we found a large reduction in fallacy rates as compared to traditional conjunction fallacy problems. Nevertheless, fallacy rates remained relatively high in both adolescents and adults, although adults showed more consistency in their normative responses. In Experiment 2, we demonstrated that children’s relatively good performance on the task was not the consequence of their missing knowledge of social stereotypes. Additionally, children were more strongly affected by explicitly presented frequency information than adults. Indeed, adults only took frequency information into account when frequencies were made relevant by a training in probabilistic reasoning. Overall, the results suggest that whereas the potential for normative reasoning increases with development, this potential is often overshadowed by a pervasive tendency in adolescence and adulthood to rely on contextual information, knowledge, and beliefs, even when conflicting information is available. By contrast, children are more strongly influenced by explicitly presented information than relevant knowledge cued by the tasks.     

Muscular Activation Pattern of Bilateral Extensors Response to Asymmetric Hand Lifting During Trunk Flexion–extension Performance

The authors' purpose was to test the effect of asymmetric hand lifting on muscular activation patterns of 3 bilateral extensors. Eighteen male university students without back pain were volunteered. Each performed flexion–extension randomly with conditions of right lifting, left lifting, and nonlifting. Surface electromyography from bilateral thoracic, lumbar erector spinae, and hamstring was recorded. The cross-correlation and relative intensity in paired muscles of bilateral extensors was calculated in flexion as well as extension period. The results showed that the cross-correlation coefficient was decreased and the phase lag as well as the relative intensity of bilateral extensors was increased significantly in thoracic level. The phase lag as well as the relative intensity of bilateral extensors was increased significantly in lumbar level. It was concluded that asymmetric lifting has a significant effect on muscular activation of bilateral extensors in thorax level, which causes the ipsilateral extensor to activate larger and longer. Asymmetric lifting also has some effect on muscular activation of bilateral extensors in lumbar level but with less extent than in thorax level, which causes contralateral extensor to activate larger and longer. Asymmetric lifting seems to have no significant effect on muscular activation of bilateral hamstring.     

A method for detailed movement pattern analysis of tadpole startle response

Prolonged space flight, specifically microgravity, presents a problem for space exploration. Animal models with altered connections of the vestibular ear, and thus altered gravity sensation, would allow the examination of the effects of microgravity and how various countermeasures can establish normal function. We describe an experimental apparatus to monitor the effects of ear manipulations to generate asymmetric gravity input on the tadpole escape response. To perform the movement pattern analysis, an imaging apparatus was developed that uses a high‐speed camera to obtain time‐resolved, high‐resolution images of tadpole movements. Movements were recorded in a temperature‐controlled test chamber following mechanical stimulation with a solenoid actuator, to elicit a C‐start response. Temperature within the test cell was controlled with a recirculating water bath. Xenopus laevis embryos were obtained using a standard fertilization technique. Tadpole response to a controlled perturbation was recorded in unprecedented detail and the approach was validated by describing the distinct differences in response between normal and one‐eared tadpoles. The experimental apparatus and methods form an important element of a rigorous investigation into the response of the tadpole vestibular system to mechanical and biochemical manipulations, and can ultimately contribute to improved understanding of the effects of altered gravity perception on humans.     

Estimating Between-Person and Within-Person Subscore Reliability with Profile Analysis

Subscores are of increasing interest in educational and psychological testing due to their diagnostic function for evaluating examinees' strengths and weaknesses within particular domains of knowledge. Previous studies about the utility of subscores have mostly focused on the overall reliability of individual subscores and ignored the fact that subscores should be distinct and have added value over the total score. This study introduces a profile reliability approach that partitions the overall subscore reliability into within-person and between-person subscore reliability. The estimation of between-person reliability and within-person reliability coefficients is demonstrated using subscores from number-correct scoring, unidimensional and multidimensional item response theory scoring, and augmented scoring approaches via a simulation study and a real data study. The effects of various testing conditions, such as subtest length, correlations among subscores, and the number of subtests, are examined. Results indicate that there is a substantial trade-off between within-person and between-person reliability of subscores. Profile reliability coefficients can be useful in determining the extent to which subscores provide distinct and reliable information under various testing conditions.     

主客体互倚性的成对模式及其检验

主客体互倚性模型（APIM）以成对数据作为分析单元,是成对数据分析的重要方法。基于APIM中的主体效应与客体效应,Kenny等人论述了APIM的四种成对模式：主体模式、客体模式、对偶模式与对比模式。通过定义客体效应与主体效应的比值为k,Kenny等人提出了定量指标,以分析主客体互倚性的成对模式。成对模式分析有助于简化数据结果、检验理论模型、解析群体互动过程。虽然k值的检验程序较为复杂,但APIM成对模式及k值的提出,对于成对数据分析,特别是家庭研究与组织心理学研究具有重要意义。     

关于两项样例学习心理实验研究报告的分析与评论

对两项关于样例学习心理实验研究的报告进行了逻辑分析,指出了Ross的研究设计的合理性以及莫雷等的 “表面概貌对原理运用的影响的实验研究”中的逻辑欠缺,进而给出了莫雷等的结论“样例与作业问题表面概貌的相似性,不仅会影响原理的通达,而且也会影响原理的运用” 尚不足信的断言,所以只能继续维持Ross的“表面概貌是否相似不影响原理的运用”的结论。最后明确了莫雷等实验研究应该采取的正确设计思路和方法。

夫妻价值观相似性、沟通模式与婚姻质量的关系*

夫妻相似性和婚姻质量的关系一直是婚姻适应研究领域关注的重要课题,然而至今并没有得到一致的结论,而且两者间的作用机制也没有得到充分探讨。为此,从澳门选取132对夫妻,采用夫妻独立作答的方式,对他们的价值观,沟通模式和婚姻适应进行测查,以探讨夫妻价值观的相似性和差异,以及沟通在夫妻价值观相似性和婚姻质量两者关系间的作用。经t检验、阶层内相关和结构方差模型分析,结果发现:(1)夫妻在价值观方面存在相似性,其实夫妻的相似性明显多于随机配对的夫妻;也存在差异,其中丈夫比妻子更看重权力和成就;(2)丈夫报告的双方回避沟通明显多于妻子,但其报告的婚姻满意度和情感表达明显好于妻子;(3)研究不仅验证了以往研究结果,即夫妻越相似,其婚姻质量就越高,而且进一步发现这种关系通过沟通起作用。最后,研究得出结论,伴侣选择应是相似和互补结合的产物,而沟通是夫妻关系的基石。     

11~14岁超常儿童与普通儿童问题解决能力的发展比较

以北京市某中学和某小学11~14岁之间294名学生为被试, 其中超常儿童131人, 普通儿童163人。采用推箱子任务, 结合横向比较和纵向追踪数据, 从认知能力、元认知能力和认知效率三个维度来考察超常儿童与普通儿童问题解决能力的发展差异。结果发现超常儿童在问题解决能力的三个维度上均优于普通儿童, 两类儿童问题解决能力的发展模式不一致：超常儿童的问题解决能力发展先快后慢, 快速发展期在11~12岁半之间; 普通儿童的问题解决能力发展先慢后快, 快速发展期在12岁半~14岁之间。超常儿童与普通儿童的问题解决能力差异随年龄增大逐渐减小。
