本文就脾虚与胃黏膜损伤的相关性从中医发病学、病机关联观、证型归纳属性及治法归类等4个方面,进行了理论探讨。认为中医脾虚的病理状态为胃黏膜损伤提供了客观条件,而胃黏膜损伤因素则又易加重脾虚证候,二者间存在着互为因果的相关关系。其观点为构建“从脾虚论治”胃黏膜损伤性疾病的治则观提供了理论基础。 相似文献

建构水平理论(Construal level theory)认为时间能够独立地改变评价对象的建构水平,从而对对象的不同特征赋予不同的权重。个体倾向于用抽象的整体的特征表征时距远的事物,而用具体的局部的特征表征时距近的事物。空间距离不同的评价对象是否也遵循同样的规律?在考察时空距离与个人相关性的基础上,通过2(时间距离:明天和十年后)×2(空间距离:近地点和远地点)×2(特征类型:样例特征和类型特征)三因素被试间实验设计,探讨时间距离、空间距离、特征类型对态度的影响。结果发现,空间距离影响人们对事物的态度。在远空间距离水平上,时间距离对态度的影响显著,而在近空间距离水平上时间距离对态度的影响不显著;在远空间条件下,时距远的对象优先注意类型化的特征,时距近的对象优先注意样例化特征。最后,在建构水平理论框架内讨论了实验结果。 相似文献

人们对于地表斜坡的知觉是非常不准确的,通常表现为对坡度估计过高。但是,研究发现,在以行为的方式对坡度进行模拟时,所模拟的坡度值却与实际坡度基本一致。这种面对同一视觉线索出现的视知觉与行为不一致的现象即为坡度知觉中的“知觉-行为分离”。本文回顾了影响坡度知觉的各种因素,涉及视觉线索、认知判断、感觉通道、生理状态以及报告方式等方面的研究,并对坡度知觉的未来研究进行了展望。 相似文献

This research investigates whether low-literate consumers process written advertisements differently than high-literate consumers do. Consistent with resource-matching theory (RMT), the first experiment reveals that, unlike high-literate processors, when low-literate processors read ads of moderate complexity, involvement with the ad does not affect processing. The second experiment extends RMT's applicability to both low- and high-literate consumers by demonstrating that low-literate processors' reading outcomes mirror those of high-literate processors when ads are written to reflect their reading capability. 相似文献

Initial evidence suggests that suppressing a thought prior to sleep results in subsequent dreaming of that thought. The present research examined the influence of cognitive load on dreaming following suppression. In Experiment 1, 100 participants received either a suppression instruction or no instruction for an intrusive thought prior to sleep, and subsequently completed a dream diary. Participants instructed to suppress reported dreaming about the target thought more than controls; dream rebound was predicted by poorer performance on a working memory task. In Experiment 2, 126 participants received either a suppression instruction or no instruction for an intrusive thought prior to sleep, and half of participants also had cognitive load of learning a 9-digit number. Participants receiving the suppression instruction under cognitive load reported greater dream rebound than other participants. These findings indicate that thought suppression prior to sleep leads to dream rebound, and this effect is enhanced by cognitive load. 相似文献

Using an item‐response theory‐based approach (i.e. likelihood ratio test with an iterative procedure), we examined the equivalence of the Rosenberg Self‐Esteem Scale (RSES) in a sample of US and Chinese college students. Results from the differential item functioning (DIF) analysis showed that the RSES was not fully equivalent at the item level, as well as at the scale level. The two cultural groups did not use the scale comparably, with the US students showing more extreme responses than the Chinese students. Moreover, we evaluated the practical impact of DIF and found that cultural differences in average self‐esteem scores disappeared after the DIF was taken into account. In the present study, we discuss the implications of our findings for cross‐cultural research and provide suggestions for future studies using the RSES in China. 相似文献

Objectives
Perfectionism is thought to energise high quantities of motivation; however, its wider influence on the quality of the motivation exhibited by athletes is less clear. The purpose of this study was to examine the multivariate and univariate relationship between multidimensional perfectionism (perfectionistic concerns and perfectionistic striving) and perceived psychological need thwarting. Perfectionistic concerns was assessed via sub-dimensions of socially prescribed perfectionism, concern over mistakes, doubts about actions, parental pressure and coach pressure. Perfectionistic striving was assessed via sub-dimensions of self-oriented perfectionism, other-oriented perfectionism, personal standards and a need for organisation.Design
A cross-sectional, survey-based design was employed.Method
One hundred and ninety-nine junior sports participants were recruited from after-school sports clubs and completed measures of multidimensional perfectionism and psychological need thwarting.Results
Canonical correlation analyses revealed that higher levels of perfectionistic concerns were associated with higher levels of perceived psychological need thwarting. Analogously, lower levels of perfectionistic striving were associated with lower levels of perceived psychological need thwarting. Regression analyses revealed that the relative importance of individual sub-dimensions of perfectionism differed depending on the facet of psychological need thwarting being assessed. Perceptions of parental pressure, coach pressure and concern over mistakes emerged as especially important.Conclusion
Overall, the findings indicate that while perfectionism may contribute to high levels of behavioural investment, it may also impoverish the necessary support required for the fulfilment of psychological needs. 相似文献860.
