Two self-paced reading experiments using a paraphrase decision task paradigm were performed to investigate how sentence complexity contributed to the relative clause (RC) attachment preferences of speakers of different working memory capacities (WMCs). Experiment 1 (English) showed working memory effects on relative clause processing in both offline RC attachment preferences and in online reading time measures, but no effects of syntactic complexity. In Experiment 2 (Korean), syntactic complexity due to greater distance between integrating heads, as measured by the dependency locality theory (Gibson in Cognition 68:1–76, 1998), significantly increased the proportion of attachment to NP1. However, no effects of working memory were found. The difference in results between English and Korean is proposed to be due to head-directionality effects. The results of our study support the conclusion that working memory-based accounts provide a better explanation than previous language-dependent accounts for differences in RC attachment preferences. We propose that previous language dependent-accounts of cross-linguistic differences in RC processing have overlooked the interaction between individual WMC and a language’s general structure, which is a central factor in RC attachment. 相似文献

A nearly abrupt coarsening of grains is observed in a newly developed Fe–Al–O ultra-fine-grained nanocomposite with a significant volume fraction (4%) of alumina nano-precipitates. The microstructure of the alloy was analysed in different states (as-received and annealed) by means of scanning electron microscopy, transmission electron microscopy (TEM) and hardness. The initial grain size 150–200 nm increases up to 50 μm during annealing 1000 °C/8 h and thereafter demonstrates saturation. A linear correlation between volume fraction of coarse grains and hardness was found. It was identified by TEM that alumina nano-precipitates stabilize the dislocation microstructure against recovery very effectively and the grain coarsening is due to fast growth of very few dislocation free grains. Thus, the observed grain coarsening has the attributes of static recrystallization. 相似文献

元认知监控包括自我监控和监控他人。本研究用两个实验分别探讨了小学低年级学生自我监控和监控他人之间的关系及其发展趋势。实验一采用100以内加减法的计算任务,来探讨小学低年级学生的自我监测和监测他人。实验二采用难度不同、分值不同的计算任务,来探讨学生的自我控制和控制他人。研究发现:第一,小学低年级学生的自我监测和监测他人都会以前期任务表现为依据,支持MPT假说。而且,自我监测和监测他人都在二年级表现出了明显的转化和提高。第二,小学低年级学生在监测他人时,逐渐由以自我信息为依据调整到以他人认知状态为依据。第三,元认知控制能力的发展落后于监测能力。二年级和三年级学生仍旧不能很合理地进行自我执行和计划他人。 相似文献

Literature concerning group ethical decision making in a business setting has traditionally focused on directly comparing group versus individual decisions and then investigating differences. Analysis of the interactive process of group ethical decision making appears sparse. This study addresses the gap by investigating group decision making from a social decision scheme (SDS) perspective in a Chinese cultural setting. A cohort of Chinese accountancy students evaluated ethical business scenarios individually and then in a group context. Group responses could be explained in terms of both the SDS and the Chinese cultural perspective (zhongyong). Specifically, groups did not select the most ethical choice but rather the most moderate of all choices advocated by the majority (zhongyong). These results show the application of SDS theory in a culturally specific (Chinese) environment and note the impact of culturally specific factors (zhongyong) on business decision making. The implications are significant for business. If ethical decisions are entrusted to groups, the impact of culturally specific factors must be fully appreciated in evaluating the final decision. 相似文献

Previous studies have demonstrated that humans have a remarkable capacity to memorise a large number of scenes. The research on memorability has shown that memory performance can be predicted by the content of an image. We explored how remembering an image is affected by the image properties within the context of the reference set, including the extent to which it is different from its neighbours (image-space sparseness) and if it belongs to the same category as its neighbours (uniformity). We used a reference set of 2,048 scenes (64 categories), evaluated pairwise scene similarity using deep features from a pretrained convolutional neural network (CNN), and calculated the image-space sparseness and uniformity for each image. We ran three memory experiments, varying the memory workload with experiment length and colour/greyscale presentation. We measured the sensitivity and criterion value changes as a function of image-space sparseness and uniformity. Across all three experiments, we found separate effects of 1) sparseness on memory sensitivity, and 2) uniformity on the recognition criterion. People better remembered (and correctly rejected) images that were more separated from others. People tended to make more false alarms and fewer miss errors in images from categorically uniform portions of the image-space. We propose that both image-space properties affect human decisions when recognising images. Additionally, we found that colour presentation did not yield better memory performance over grayscale images. 相似文献

Using tournament theory as a guiding theoretical framework, in this study, we assess the organizational implications of pay dispersion and other pay system characteristics on the likelihood of turnover among individual executives in organizational teams. Specifically, we estimate the effect of these pay system characteristics on executive turnover decisions. We use a multi-industry, multilevel data set composed of executives in publicly held firms to assess the effects of pay dispersion at the individual level. Consistent with previous findings, we find that pay dispersion is associated with an increased likelihood of executive turnover. In addition, we find that other pay characteristics also affect turnover, both directly and through a moderating effect on pay dispersion. Turnover is more likely when executives receive lower portions of overall top management team compensation and when they have more pay at risk. These conditions also moderate the relationship between pay dispersion and individual turnover decisions, as does receiving lower compensation relative to the market. 相似文献

This study investigated the multiple dimensions of self-perception in a sample of sexually abused and nonabused comparison
girls (n = 140), with particular attention to self-perception in the scholastic, social, athletic, physical (appearance), and behavioral
conduct domains. First, this study examined whether the five dimensions of self-perception were psychologically discrete.
Second, the relationships between the self-perception factors and childhood sexual abuse were investigated using structural
equation modeling. The results supported the multidimensionality of self-perception and suggested the presence of two distinct
second-order self-perception factors: academic- and social-self. While the sexually abused girls indicated less positive perception
for the academic-self than the comparison group, the two groups did not differ regarding the social-self. The findings highlight
the importance of a multidimensional approach to self-perception in assessing and treating sexually abused children. 相似文献
