Rare Constructions Are More Often Sentence‐Initial

Main clause phenomena (MCPs) are syntactic constructions that occur predominantly or exclusively in main clauses. I propose a processing explanation for MCPs. Sentence processing is easiest at the beginning of the sentence (requiring less search); this follows naturally from widely held assumptions about sentence processing. Because of this, a wider variety of constructions can be allowed at the beginning of the sentence without overwhelming the sentence‐processing mechanism. Unlike pragmatic and grammatical accounts of MCPs, the processing account predicts avoidance of MCPs in non‐initial main clauses (non‐initial coordinate clauses and premodified clauses). A corpus study supports these predictions, but it is somewhat inconclusive. A further corpus study examines another type of syntactic construction, premodifying adjunct phrases (“openers”); the prediction here is that less common types of opener will be especially avoided in non‐initial contexts. The prediction is confirmed, supporting the processing view of rare constructions.     

“Seeing Rain”: Integrating phenomenological and Bayesian predictive coding approaches to visual hallucinations and self-disturbances (Ichstörungen) in schizophrenia

We present a schizophrenia patient who reports “seeing rain” with attendant somatosensory features which separate him from his surroundings. Because visual/multimodal hallucinations are understudied in schizophrenia, we examine a case history to determine the role of these hallucinations in self-disturbances (Ichstörungen). Developed by the early Heidelberg School, self-disturbances comprise two components: 1. The self experiences its own automatic processing as alien to self in a split-off, “doubled-I.” 2. In “I-paralysis,” the disruption to automatic processing is now outside the self in omnipotent agents. Self-disturbances (as indicated by visual/multimodal hallucinations) involve impairment in the ability to predict moment-to-moment experiences in the ongoing perception-action cycle. The phenomenological approach to subjective experience of self-disturbances complements efforts to model psychosis using the computational framework of hierarchical predictive coding. We conclude that self-disturbances play an adaptive, compensatory role following the uncoupling of perception and action, and possibly, other low-level perceptual anomalies.     

音乐训练促进诗句韵律整合加工的神经过程

本研究采用ERP技术,考察音乐训练组和对照组完成诗句押韵判断任务时,在绝句末对韵律信息(含声调和韵母两个维度)的整合加工过程。结果发现,在100～300 ms,仅音乐训练组在声调/韵母合适条件下,对韵母/声调的一致性进行深入分析,并诱发了更大的正波;在韵母违反条件下,声调违反相比声调合适诱发了更小的正波。在300～750ms,两组被试均在绝句末对诗句内出现的韵母和声调违反进行整合分析并诱发了广泛分布的负波。不过,对照组仅在声调/韵母合适条件下进行,而音乐训练组则在声调/韵母违反条件下完成此过程。综上,音乐训练组和对照组均会在诗句末完成押韵信息的整合加工,但是音乐训练组对韵律信息(尤其是声调)的加工更敏感和快速,并且对不同类型的违反有更精细的差异性反应     

数据权属与规制探讨

数据可分为原生数据与衍生数据。原生数据视来源不同分属国家、集体或个人。数据处理而形成的衍生数据往往涉及多方利益,形成“利益光谱”,对应多方权利主体。基于价值优先次序、权利位阶规则等,数据利益的“两头强化,多方平衡”,是我国法律数据确权和规制的指导思想。“两头强化”是指法律强化对位于“利益光谱”两端的国家利益与个人权益的保护,“多方平衡”指的是多方主体数据权益的平衡。数据规制的“硬法”进路为：明确法律概念,分析“利益光谱”,确定利益归属,权衡优先次序,平衡多方利益,搭建规制框架,制定具体规则。

     

Measuring information demand of a dynamic in-vehicle display while driving – A study evaluating the MARS (Masking Action Relevant Stimuli) method

The MARS (Masking Action Relevant Stimuli) method assesses information demand for dynamic stimuli while driving. An action relevant stimulus is masked and the driver presses a button to unmask the stimulus for a limited period. We interpreted button presses as information demand. Following our previous research (Rittger, Kiesel, Schmidt, & Maag, 2014), the current study further evaluates the method. We applied the MARS method to a dynamic in-vehicle display containing recommendations from a traffic light assistant. In a driving simulator, drivers approached intersections with different traffic light phasing. The display either presented simple or complex information. In half of the drives, the participants used the MARS method. The study had a full within subjects design and fixations were recorded in all conditions. The results showed that the information demand varied according to the information in the display and the traffic light phase. A comparison of button presses with fixations showed that one unmasking interval came along with one fixation on the display. As a conclusion, the MARS method can distinguish between conditions with high and low information demand for the display. Button presses relate to fixations on the display. Hence, the MARS method is a promising tool to assess the information demand in dynamic environments and can be applied as an extension or alternative for eye tracking.     

汉字字谜任务中限制解除的电生理机制

尽管“限制解除”作为一种顿悟问题解决的关键途径早在上世纪90年代就被德国心理学者Knoblich及其同事提出, 但学界对于“限制解除”所包含的信息加工程序、阶段以及相应的脑认知过程却并未有进一步的探讨和细化。本文从“限制解除”的理论角度出发, 以答案提示催化的“诱发式”字谜解决顿悟为例, 首次提出了一个关于“诱发式”限制解除过程的信息加工阶段初步构想。该构想认为：顿悟问题解决中的“诱发式”限制解除过程包含3个不同的信息加工阶段。第一阶段是以早期注意参与为特征的冲突信息的预警或预处理过程; 第二阶段是以新旧思路交替为特征的关键限制解除过程, 鉴于这个过程以基本问题表征空间的拓展为特征, 因此我们推测右脑的活动很有可能在这个过程中占据主导地位; 第三阶段是以自上而下的控制加工为特征的重新整合过程。脑电研究数据部分地支持了本研究的假设, 发现了上述第一阶段在脑电变化上体现为顿悟性限制解除所伴随的N100/P200复合体; 第二阶段体现为P300在300~400 ms的时间窗内的地形图分布及差异波; 而第三阶段则体现为N400在400~800 ms内的变化。脑电结果还证实：在第二阶段也就是限制解除的关键阶段, 右脑的活动明显强于左脑, 提示基本问题空间的拓展可能更多地依赖于右脑, 而在第三阶段也就是信息的重新整合阶段则表现出相反的半球偏侧化倾向。上述发现有可能为进一步认识和理解顿悟中“限制解除”的脑认知机理提供了新的见解。
