注意负荷对内隐序列学习的影响研究

运用次级任务研究范式,采用符号计数的次级任务和歧义序列中的次级条件序列,将内隐序列学习分为单任务组和双任务组,统一在单任务条件下测试。结果发现:(1)两组被试内隐学习成绩差异不显著;(2)双任务组被试在学习组块和测试组块的内隐学习差异也不显著。结果进一步支持了在次级任务占用注意资源的条件下内隐学习仍然可以正常地获得、内隐序列学习不受注意负荷影响的观点。     

Short-term memory for serial order supports vocabulary development: New evidence from a novel word learning paradigm

Although recent studies suggest a strong association between short-term memory (STM) for serial order and lexical development, the precise mechanisms linking the two domains remain to be determined. This study explored the nature of these mechanisms via a microanalysis of performance on serial order STM and novel word learning tasks. In the experiment, 6- and 7-year-old children were administered tasks maximizing STM for either item or serial order information as well as paired-associate learning tasks involving the learning of novel words, visual symbols, or familiar word pair associations. Learning abilities for novel words were specifically predicted by serial order STM abilities. A measure estimating the precision of serial order coding predicted the rate of correct repetitions and the rate of phoneme migration errors during the novel word learning process. In line with recent theoretical accounts, these results suggest that serial order STM supports vocabulary development via ordered and detailed reactivation of the novel phonological sequences that characterize new words.     

Item grouping and item randomization in personality measurement

This paper describes a study examining the impact of item order in personality measurement on reliability, measurement equivalence and scale-level correlations. A large sample of university students completed one of three forms of the International Personality Item Pool version of the Big Five personality inventory: items sorted at random, items sorted by factor, and items cycled through factors. Results showed that the underlying measurement model and the internal consistency of the IPIP-Big Five scale was unaffected by differences in item order. Also, most of the scale-level correlations among factors were not significantly different across forms. Implications for the administration of tests and interpretation of test scores are discussed, and future research directions are offered.     

Impact of auditory selective attention on verbal short-term memory and vocabulary development

This study investigated the role of auditory selective attention capacities as a possible mediator of the well-established association between verbal short-term memory (STM) and vocabulary development. A total of 47 6- and 7-year-olds were administered verbal immediate serial recall and auditory attention tasks. Both task types probed processing of item and serial order information because recent studies have shown this distinction to be critical when exploring relations between STM and lexical development. Multiple regression and variance partitioning analyses highlighted two variables as determinants of vocabulary development: (a) a serial order processing variable shared by STM order recall and a selective attention task for sequence information and (b) an attentional variable shared by selective attention measures targeting item or sequence information. The current study highlights the need for integrative STM models, accounting for conjoined influences of attentional capacities and serial order processing capacities on STM performance and the establishment of the lexical language network.     

On ethical order

The existent ethical relationships are the result of the historical amalgamation of objective and subjective conditions. Ethical relationships are essential relationships in the real and rational order, which are maintained by a system of regulations on morals, laws and customs, and infused with a spirit of subjectivity. Rationality and legitimacy are the primary concerns of those relationships. A distinction between morals and ethos needs to be made when studying ethical order. Sound ethical order lies in effective regulation of morals and effective control of law. In the process of social reform, ethical order promotes social development through the dialectical movement of freedom and necessity. A harmonious society is a society which is based on legitimate and just ethical order. Translated by Cui Hui from Lunlixue yanjiu 伦理学研究 (Studies in Ethics), 2007, (5): 1–8     

The role of the right posterior parietal cortex in temporal order judgment

Perceived order of two consecutive stimuli may not correspond to the order of their physical onsets. Such a disagreement presumably results from a difference in the speed of stimulus processing toward central decision mechanisms. Since previous evidence suggests that the right posterior parietal cortex (PPC) plays a role in modulating the processing speed of a visual target, we applied single-pulse TMS over the region in 14 normal subjects, while they judged the temporal order of two consecutive visual stimuli. Stimulus-onset-asynchrony (SOA) randomly varied between -100 and 100 ms in 20-ms steps (with a positive SOA when a target appeared on the right hemi-field before the other on the left), and a point of subjective simultaneity was measured for individual subjects. TMS stimulation was time-locked at 50, 100, 150, and 200 ms after the onset of the first stimulus, and results in trials with TMS on right PPC were compared with those in trials without TMS. TMS over the right PPC delayed the detection of a visual target in the contralateral, i.e., left hemi-field by 24 (+/-7 SE) ms and 16 (+/-4 SE) ms, when the stimulation was given at 50 and 100 ms after the first target onset. In contrast, TMS on the left PPC was not effective. These results show that the right PPC is important in a timely detection of a target appearing on the left visual field, especially in competition with another target simultaneously appearing in the opposite field.

Revisiting Westphalia, Discovering Post-westphalia

This article explores the structure of world order fromthe perspective of the Treaty of Westphalia, which is treated asthe benchmark for the emergence of the modern system of sovereignstates. Emphasis is placed on Westphalia as historical event, ideaand ideal, and process of evolution, and also on developments thatsupersede this framing of world politics, especially, globalizationand the megaterrorist challenge of September 11, 2001. At issue is whether the state system is resilient enough to adapt to new globalconditions or is in the process of being supplanted, and whether thesequel to Westphalia is moving toward humane global governance orsome dysutopic variant, or both at once.     

王夫之“阴阳向背”说的本体意义

王夫之阴阳十二位向背是根据乾坤并建之体的性质及体用一源的原理引申、推论出来的,他用这一原理来批评象数学的机械排比和框定,并用事物的自然自足、自立自全的性质,证明《序卦传》的三种卦序说不能成立,为自己独特的卦序说奠立基础。他要证明的哲学原理是,显现有向背,阳阳无或缺;本体所具有的性质与功能,同时就具于个体之中,个体因此而有了主体性、能动性,和自由地独立活动的品格。     

龟卜筮占的递兴与《易》卦符号的性质

先民信奉的术数有天启与人为之別。天启是消极被动地等待"天垂象,示吉凶",人为则是以卜筮"决嫌疑,定犹豫"。龟卜繁难,筮占简易。殷人尚卜与周人用筮,实为不同民族的稽疑习惯。周人受封于商,殷周始有文化往来,而周人迁岐之后,殷人之龟卜乃行于周邦,但周人仍以筮占为主。周朝开国立基,依其传统的稽疑之法编纂筮书,称之为《易》,其命名之朔,正是着眼于龟卜的繁难与筮占的简易。而《周易》卦爻辞乃旧有之象占、星占及筮占甚至龟卜之辞的鸠合与改编,具有相当程度的加工与润色。六十四卦卦画符号的原初功能就是"纪数"与"检索"。内"贞"外"悔"的爻辞顺序,也是针对六十四卦卦画绝大多数皆可"表里视之,遂成两卦"所作的规定。因此,《易》之所以名"易",一是相对龟卜而言,筮占简单容易;二是筮书编成之后,卦画符号具有方便的检索功能。而各种不同的筮法,皆可视为筮书的不同检索方式。
