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

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

This paper outlines the ways in which an individual’s notions of sexuality are challenged by immigration. It describes four basic facets of sexuality and the ways in which each are rooted in culture. These include (1) the relative importance of sexuality in daily life; (2) potential or overt homosexuality; (3) marriage—whether based on arrangement or love; and (4) cross-cultural romantic and marital relationships. Immigration can stir up conflicts in each of these realms and lead to defensive retreat into familiar customs or a counterphasic plunge into new cultural avenues. Ideally, it would lead to a working-through of these conflicts and subsequent growth in the immigrant’s understanding of his or her sexual self.  相似文献

Borderline patients present particular treatment problems and require close, devoted understanding of their often chaotic and shifting intrapsychic conflicts. Many of these patients act out, making it difficult to maintain an analytic process. In fact, many terminate early on. When they do stay for longer periods, they exhibit particular constellations of defense, anxiety, and conflict. One extensive case report is used to examine the overlapping cycles of treatment with this population. Frequently, self-destructive acting-out is present in the transference and extratransference. This acting-out is often followed by the self-destructive, antichange attitude of the death instinct. These ways of relating to the self and the object are mobilized within the vehicle of projective identification and are best understood as primitive defenses against core fantasies of loss and persecution. These issues of loss and fear are the final and vital phase of treatment with borderline patients, who are often able to make major fundamental changes in their internal sphere, but only if patient and analyst can tolerate and understand these three levels of intrapsychic experience.  相似文献
