奏鸣曲式中调性结构对紧张感的影响——以莫扎特与贝多芬钢琴奏鸣曲为例

音乐紧张感是音乐聆听的基础与重要环节。本研究选取莫扎特与贝多芬的音乐作品, 运用紧张感模型计算与行为实验两种方法, 探讨奏鸣曲式中的调性结构对紧张感的影响。研究发现, 奏鸣曲中呈示部、展开部与再现部三部分的紧张感变化具有差异, 展开部的紧张感高于呈示部与再现部, 再现部的紧张感高于呈示部, 这源于转调距离与转调频率的差异。本研究探讨了在大尺度的真实音乐作品中调性结构对紧张感的影响, 为音乐学领域的研究提供佐证和新的视角。     

镜像等效或守恒及其打破：从行为到认知神经机制的研究证据

镜像等效或守恒是动物与人类个体对两侧对称自然物体的一种进化自适应加工。但是, 这种知觉特性会妨碍包含镜像字符的文字阅读学习。阅读者有必要学会利用镜像泛化抑制的“去学习”机制, 打破镜像等效或守恒, 以获得识别镜像字符的能力。这一过程中, 左侧梭状回皮层通过与早期视觉皮层、顶叶皮层和口语脑网络的交互作用, 逐渐发展出一个可以识别镜像字符的视觉词形区(visual word form area, VWFA)。今后的研究需要关注两半球及其连合纤维在镜像等效或守恒加工中的作用、镜像泛化与抑制的详尽加工机制及其对镜像书写的影响、正常汉语儿童的汉字镜像泛化加工等问题。     

Roles of personal and environmental factors in the red light running propensity of pedestrian: Case study at the urban crosswalks

Pedestrian is vulnerable to mortality and severe injury in road crashes. Red light running violation of pedestrians is one of the leading causes to the crashes at signalized intersections, at which the crash involvement rates of pedestrians are high. Therefore, it is important to identify the factors that affect the propensity of red light running of pedestrian. In this study, effects of both personal factors (pedestrians’ demographics and behavior) and environmental factors (presence and behavior of other pedestrians, signal time, and traffic condition) on the individual decision of red light running violation are examined, using the video observation surveys at the signalized crossings that are prone to pedestrian-vehicle crashes and have moderate pedestrian and vehicular traffic volumes in the urban area. Crossing behaviors of 6320 pedestrians are captured. Results of a random parameter logit model indicate that pedestrian gender, age, number of lanes, presence of a companion, number of pedestrians around, presence of other violators in the same cycle, time to green, red time, traffic volume, and percentage of heavy vehicles all affect the propensity of red light running violation of pedestrians. Also, there are significant interaction effects by pedestrian’s gender and age, presence of other violators, with a companion, and traffic volume on the propensity. Findings are indicative to the development of effective engineering, enforcement and educational initiatives combating the red light running violation behavior of pedestrians. Therefore, pedestrian safety level at the signalized intersections can be enhanced.     

A Note on Formality and Logical Consequence

Logic is formal in the sense that all arguments of the same form as logically valid arguments are also logically valid and hence truth-preserving. However, it is not known whether all arguments that are valid in the usual model-theoretic sense are truth-preserving. Tarski claimed that it could be proved that all arguments that are valid (in the sense of validity he contemplated in his 1936 paper on logical consequence) are truth-preserving. But he did not offer the proof. The question arises whether the usual model-theoretic sense of validity and Tarski's 1936 sense are the same. I argue in this paper that they probably are not, and that the proof Tarski had in mind, although unusable to prove that model-theoretically valid arguments are truth-preserving, can be used to prove that arguments valid in Tarski's 1936 sense are truth-preserving.     

特征觉察器与康德的先验形式

康德主张对象必须符合主体的认识条件,即与特定的形式相符合,这与认知心理学上的特征觉察器相一致。特征觉察器是对特定的刺激物作出特定反应的高级神经元组织。康德的先验形式的问题可以用特征觉察器和特征捆绑等神经组织和神经过程来解释。特征觉察器可为审美先验形式提供生理心理基础,也可以使康德美学的主客之争得到相对缓解。     

Global shape integration and illusory form perception in the absence of awareness

Previous research on perceptual organization operations still provides contradictory evidence on whether the integration of sparse local elements into coherently unified shapes and the construction of the illusory form are accomplished without the need of awareness. In the present study, three experiments were conducted in which participants were presented with masked (Experiment 1, SOA = 27 ms; Experiment 2; SOA = 53 ms) and unmasked (Experiment 3) primes consisting of geometric shapes (a square or a diamond) that could be congruent or incongruent with subsequent probe stimuli (square vs. diamond). Furthermore, the primes were divided into: a grouping condition (where local elements may group together into global shapes), an illusory condition (where the arrangement of local elements produced illusory shapes) and a hybrid condition (where both operations were presented simultaneously). While no priming effects were found for the shortest SOA (27 ms), both grouping and illusory primes produced significant priming effects in the longer SOA (53 ms). On the other hand, results in Experiment 3 (unmasked) showed strong priming effects for the grouping of the inducers in both the grouping and the hybrid conditions, and also a significant but weaker priming effect for the illusory condition. Overall, our results support the possibility of the integration of local visual features into a global shape in the absence of awareness and, likewise, they suggest an early –subliminal– construction of the illusory shape, implying that feedback projections from higher to lower visual areas are not crucial in the construction of the illusory form.     

Play enhances visual form perception in infancy–an active training study

Motor experiences and active exploration during early childhood may affect individual differences in a wide range of perceptual and cognitive abilities. In the current study, we suggest that active exploration of objects facilitates the ability to process object forms and magnitudes, which in turn impacts the development of numerosity perception. We tested our hypothesis by conducting a preregistered active exploration intervention with 59 8‐month‐old infants. The minimal intervention consisted of actively playing with and exploring blocks once a day for 8 weeks. In order to control for possible training effects on attention, we used book reading as a control condition. Pre‐ and post‐test assessments using eye‐tracking showed that block play improved visual form perception, where infants became better at detecting a deviant shape. Furthermore, using three control tasks, we showed that the intervention specifically improved infants' ability to process visual forms and the effect could not be explained by a domain general improvement in attention or visual perception. We found that the intervention did not improve numerosity perception and suggest that because of the sequential nature of our hypothesis, a longer time frame might be needed to see improvements in this ability. Our findings indicate that if infants are given more opportunities for play and exploration, it will have positive effects on their visual form perception, which in turn could help their understanding of geometrical concepts.     

Baseline measurement of running away among youth in foster care

The current study evaluated the use of various behavioral measures of running away with regard to (a) the differential utility of interval- versus event-based measures, (b) the differential utility of rate versus duration measures, (c) the utility of correcting for occurrence opportunity, and (d) the influence of unit of analysis (i.e., single-subject vs. grouped data). Seven different baseline measures were calculated for 84 runaways, and a unit-size analysis was conducted by constructing groups of various sizes from the original sample. An expert panel evaluated the suitability of the baseline measures for treatment evaluation. Results demonstrate the utility of evaluating duration-based measures and correcting for occurrence opportunity. Results also indicate that single-subject baselines may often be unacceptable for treatment evaluations, regardless of the type of measure selected for use.     

The Information Coding Classification (ICC): A Modern,Theory-Based Fully-Faceted,Universal System of Knowledge Fields

Introduction into the structure, contents and specifications (especially the Systematifier) of the Information Coding Classification, developed in the seventies and used in many ways by the author and a few others following its publication in 1982. Its theoretical basis is explained consisting in (1) the Integrative Level Theory, following an evolutionary approach of ontical areas, and integrating also on each level the aspects contained in the sequence of the levels, (2) the distinction between categories of form and categories of being, (3) the application of a feature of Systems Theory (namely the element position plan) and (4) the inclusion of a concept theory, distinguishing four kinds of relationships, originated by the kinds of characteristics (which are the elements of concepts to be derived from the statements on the properties of referents of concepts). Its special Subject Groups on each of its nine levels are outlined and the combinatory facilities at certain positions of the Systematifier are shown. Further elaboration and use have been suggested, be it only as a switching language between the six existing universal classification systems at present in use internationally.

Review of Nie Minli’s Being and Substance: On Aristotle’s Metaphysics Z1–9

In his new book Being and Substance: A Study of Aristotle’s Metaphysics Z1–9, Nie Minli, taking a holistic perspective, argues that the primary substance—that is, the individual in Categories—is identical to form, which is the primary substance in Metaphysics Z, and that Z3 has finished arguing what the real candidate of substance is and the inserted Z7–9 texts are the “core and key” of the entire book. In spite of his excellent scholarship and masterful interpretation of Metaphysics Z4–6, Z7, Categories 1–5 and Physics Α, Nie offers insufficient textual support for his interpretation of the primary substance in Metaphysics Z and the content of Z3. Although substance is the subject (hypokeimenon) and a “this” (tode ti) in Categories, it is the ultimate subject (hypokeimenon eschaton) and a “this” (tode ti) and separable (choriston) in Metaphysics. As the ultimate subject, substance is form and matter but not the individual. As a “this” (tode ti) and separable (choriston), substance is form; moreover, the primary substance is form. In my view, that form is substance in Z3 serves more as a plan or outline needed to prove in the following than as a definite conclusion. This article also points out that tode ti in Z8, 1033b21 refers to the individual but not the form. Homōnuma in Z9 cannot be understood as “sharing the same name but with different meaning,” but, rather, simply as “having the same name.”
