Cued recall success varies with what people know and with what they do during an episode. This paper focuses on prior knowledge and disentangles the relative effects of 10 features of words and their relationships on cued recall. Results are reported for correlational and multiple regression analyses of data obtained from free association norms and from 29 experiments. The 10 features were only weakly correlated with each other in the norms and, with notable exceptions, in the experiments. The regression analysis indicated that forward cue-to-target strength explained the most variance, followed by backward target-to-cue strength. Target connectivity and set size explained the next most variance, along with mediated cue-to-target strength. Finally, frequency, concreteness, shared associate strength, and cue set size also contributed significantly to recall. Taken together, indices of prior word knowledge explain 49% of the recall variance. Theoretically driven equations that use free association to predict cued recall were also evaluated. Each equation was designed to condense multiple indices of word interconnectivity into a single predictor.  相似文献

We investigated the ability of honeybees to learn mazes of four types: constant-turn mazes, in which the appropriate turn is always in the same direction in each decision chamber; zig-zag mazes, in which the appropriate turn is alternately left and right in successive decision chambers; irregular mazes, in which there is no readily apparent pattern to the turns; and variable irregular mazes, in which the bees were trained to learn several irregular mazes simultaneously. The bees were able to learn to navigate all four types of maze. Performance was best in the constant-turn mazes, somewhat poorer in the zig-zag mazes, poorer still in the irregular mazes, and poorest in the variable irregular mazes. These results demonstrate that bees do not navigate such mazes simply by memorizing the entire sequence of appropriate turns. Rather, performance in the various configurations depends on the existence of regularity in the structure of the maze and on the ease with which this regularity is recognized and learned.  相似文献

多层线性模型在纵向研究中的运用   总被引:13,自引:0,他引:13  
盖笑松  张向葵 《心理科学》2005,28(2):429-431
纵向研究中传统统计技术主要是重复测量的方差分析和多元回归分析,但是这两种技术存在一些局限性,不能合理而充分地解释纵向研究资料。近年来出现的多层线性模型能够更有效地利用纵向数据。为促进多层线性模型在纵向研究中的运用,简要论述了传统统计技术的局限,介绍了多层线性模型的原理及其在纵向研究中的作用,以一组模拟数据为例对多层线性模型中各种参数在纵向研究中的含义进行了详细讨论,对于纵向研究中运用多层线性模型时须注意的问题提出了建议。  相似文献

极权主义和政治现代性--读《极权主义的起源》   总被引:1,自引:0,他引:1  
阿伦特的《极权主义的起源》是要揭示一种特殊的现代政治现象的起因和条件,探讨极权主义这个现代特有的现象的深层历史原因及其结构因素。正因为如此,她的许多观点和分析至今仍有重要的意义。极权主义是反犹主义、民族国家的衰落、种族主义、为扩张而扩张、资本和暴徒联盟结合在一起的产物。极权主义就是从根本上消灭人性,它反映了“我们世纪的危机”,揭示了西方文明及其价值体系的崩溃。  相似文献

奥古斯丁《忏悔录》中的“时间之间”受到后世哲学家们的广泛关注和高度评价,但往往只重视其中“心灵的伸展”这一向度.而忽视上帝的创造这一向度,忽视了永恒之维。事实上,上帝的创造和心灵的伸展这两个向度不可分割.前者规定后者,阐明时间的起源;后者反映前者,说明时间的存在和本质。后者受前者的制约。也就是说,心灵的伸展有一个界限,是不可超越的。当文德尔班强调奥古斯丁的形而上学是“内在经验的形而上学”时,他确认了奥古斯丁时间观的心灵向度;当吉尔松称之为“皈依的形而上学”时,则是强调“心灵伸展的界限”,即永恒上帝的创造。  相似文献

This article reports three experiments in which the representational nature of human object location memory was studied. The results show that multiple frames of reference can be used to encode the spatial relationships among objects. Depending on their dominancy, availability, and validity, these multiple representations interact to determine memory performance. Specifically, representations that are automatically encoded and extensively practiced are more dominant, and their availability improves performance when they are valid. On the other hand, when the dominant representations are available but invalid, people may have to resort to the less dominant representations. As a result, the availability of these dominant but invalid representations can actually hurt performance, due to interference. If these interfering representations are eliminated, the performance is again improved. The implications of these findings for general human spatial cognition are discussed.  相似文献

In this paper, we discuss the weakness of current action languages for sensing actions with respect to modeling domains with multi-valued fluents. To address this problem, we propose a language with sensing actions and multi-valued fluents, called AMK, provide a transition function based semantics for the language, and demonstrate its use through several examples from the literature. We then define the entailment relationship between action theories and queries in AMK, denoted by ⊧AMK, and discuss some properties about AMK.  相似文献

This study investigated the responses of 14 giant pandas (Ailuropoda melanoleuca) to 5 enrichment items (3 manipulable objects, 2 feeding devices) that possess different properties affording varying behavioral opportunities. Enrichment items were quantitatively described by using 12 properties. Pandas displayed no preferences among the 5 enrichment treatments, all of which had similar positive effects on behavioral measures of well-being (behavioral diversity, stereotypy). However, each item promoted a distinct behavioral profile, readily mapped onto the enrichment's properties. These results suggest that it may be important to stimulate behavioral diversity but that specific behaviors or enrichment properties are not required. The unique behavioral topography seen with these enrichments also suggests that providing multiple enrichments with varying properties will maximize overall behavioral diversity.  相似文献
