声旁与笔画省略方式对形声字识别的影响

本研究通过两个实验,考察笔画省略方式和声旁对形声字识别的影响。实验一采用命名任务考察了声旁和三种笔画省略方式（省前、略后、不省）对左右结构形声字识别的影响。结果表明存在笔画顺序效应和声旁位置效应,并发现略后的笔画中有声旁,笔画顺序效应会消失。这说明声旁的作用抵消了笔画顺序效应,体现了声旁在形声字识别中的重要作用;实验二在实验一的基础上,采用上下结构的形声字,实验结果表现出了相同的趋势,且更加显著。

Comments on Plantinga’s Argument of Transworld Identity

Plantinga’s conception of possible worlds is problematic in one sense: it relies on the prior idea of modality. His strategy for resolving the puzzle of transworld identity is significant in the metaphysical sense but fruitless in the epistemological sense because world-indexed properties cannot be used as effectively in epistemic practice as their counterparts, i.e., space- and time-indexed properties. His isolation of transworld identification from transworld identity is unconvincing. This paper argues that the intelligibility of modal discourse and reference is the essence of transworld identity. It is also proved that transworld identification is the epistemic ground of such intelligibility. Hence, the transworld identification problem is the epistemological foundation of the transworld identity problem, and there must be a comprehensive answer to the former.     

汉字识别的反启动效应

为验证记忆的重叠表征理论,采用包括基线测量的启动实验范式,通过三个系列实验探讨了汉字识别的反启动效应。实验一结果表明,与基线条件相比,启动显著提高了启动的汉字的识别正确率,但却显著降低了与该汉字部分字形相同的未启动的汉字的识别正确率;实验二和三结果显示,反启动效应不是源于注意偏向和疲劳因素。因此,汉字识别中存在反启动效应,这为重叠表征理论提供了新的支持证据。     

A note on identification in the oblique and orthogonal factor analysis models

Conditions for removing the indeterminancy due to rotation are given for both the oblique and orthogonal factor analysis models. The conditions indicate why published counterexamples to conditions discussed by Jöreskog are not identifiable.The author would like to thank Gordon Bechtel and the reviewers for their comments and suggestions.     

The relative sensitivities of same-different and identification judgment models to perceptual dependence

Probabilistic models of same-different and identification judgments are compared (within each paradigm) with regard to their sensitivity to perceptual dependence or the degree to which the underlying psychological dimensions are correlated. Three same-different judgment models are compared. One is a step function or decision bound model and the other two are probabilistic variants of a similarity model proposed by Shepard. Three types of identification models are compared: decision bound models, a probabilistic multidimensional scaling model, and probabilistic models based on the Shepard-Luce choice rule. The decision bound models were found to be most sensitive to perceptual dependence, especially when there is considerable distributional overlap. The same-different model based on the city-block metric and an exponential decay similarity function, and the corresponding identification model were found to be particularly insensitive to perceptual dependence. These results suggest that if a Shepard-type similarity function accurately describes behavior, then under typical experimental conditions it should be difficult to see the effects of perceptual dependence. This result provides strong support for a perceptualindependence assumption when using these models. These theoretical results may also play an important role in studying different decision rules employed at different stages of identification training.We thank Robert Melara, Jerome Busemeyer and three anonymous reviewers for comments on an earlier draft of this paper.     

Comparing different kinds of words and word-word relations to test an habituation model of priming

Huber and O'Reilly (2003) proposed that neural habituation exists to solve a temporal parsing problem, minimizing blending between one word and the next when words are visually presented in rapid succession. They developed a neural dynamics habituation model, explaining the finding that short duration primes produce positive priming whereas long duration primes produce negative repetition priming. The model contains three layers of processing, including a visual input layer, an orthographic layer, and a lexical-semantic layer. The predicted effect of prime duration depends both on this assumed representational hierarchy and the assumption that synaptic depression underlies habituation. The current study tested these assumptions by comparing different kinds of words (e.g., words versus non-words) and different kinds of word-word relations (e.g., associative versus repetition). For each experiment, the predictions of the original model were compared to an alternative model with different representational assumptions. Experiment 1 confirmed the prediction that non-words and inverted words require longer prime durations to eliminate positive repetition priming (i.e., a slower transition from positive to negative priming). Experiment 2 confirmed the prediction that associative priming increases and then decreases with increasing prime duration, but remains positive even with long duration primes. Experiment 3 replicated the effects of repetition and associative priming using a within-subjects design and combined these effects by examining target words that were expected to repeat (e.g., viewing the target word ‘BACK' after the prime phrase ‘back to'). These results support the originally assumed representational hierarchy and more generally the role of habituation in temporal parsing and priming.     

题库结构对原始题在线属性标定准确性之影响研究

目前已有研究证明可达阵在认知诊断测验编制中起重要作用,但迄今为止并没有引起普遍注意。本文主要讨论当题库缺少某些可达阵对应的项目类,对原始题的属性向量在线标定的准确性的影响。本文对含6个属性的独立型结构进行了模拟试验,结果显示：如果题库不充要,原始题的属性标定准确性受到影响,题库中非可达阵中项目对标定有一定的弥补作用。间接印证了可达阵在认知诊断题库起到非常重要的作用。     

中文书写者字迹识别的眼动研究

采用眼动技术,以不同整体书写风格的字迹为实验材料,探讨中文字迹识别的眼动模式。实验结果显示：随着整体书写风格一致性的变化,被试识别不同书写者中文字迹的反应时、注视次数,眼跳次数,兴趣区数及落入兴趣区的比率均表现出显著性差异。结论：（1）识别中文字迹依赖字迹整体书写风格;（2）中文字迹识别模式：在识别字迹时,优先采用字迹整体书写风格识别不同的字迹;（3）中文字迹识别属于图像识别加工。     

北宋医理进展及渊源考述:以五脏辨证体系为线索

张仲景时期五脏证治概念界定边缘清晰,又能化整为零,分散于各具体证治。之后经六朝隋唐,杂病领域的积累致使内部有重新整合的刚性需求。而承载多层五脏辨证新说的七篇《大论》的出现切合发展时机。进入北宋之后,七篇《大论》没有立刻产生影响,直至仁宗时,由于国家校正医书局整理刊刻新《素问》才流行开来。随之而来,医家不断发挥新说。标志当时学术高度的是钱乙的《小儿药证直诀》,书中将化博为约、重新审察旧说、注重五脏辨证等北宋医学之新象发挥得淋漓尽致。北宋医理的突出进展,是发生于五脏辨证的学术脉络之下。
