The importance of knowledge in vivid text memory: An individual-differences investigation of recollection and familiarity

The goal of this study was to examine how individual variation in readers’ skills and, in particular, their background knowledge about a text are related to text memory. Recollection and familiarity estimates were obtained from remember and know judgments to text ideas. Recollection estimates to old items were predicted by readers’ background knowledge, but not by other comprehension-related factors, such as word-decoding skill and working memory capacity. False alarms involving recollection of new items (inferences) were diminished as a function of verbal ability, working memory capacity, and reasoning but increased as a function of background knowledge. The results suggest that recollection indexes the reader’s ability to construct a text representation in which text ideas are integrated with relevant domain knowledge. Moreover, these results highlight the importance of background knowledge in explaining individual variation in comprehension and memory for text.     

Let my people go! Sayyid Qutb and the vocation of Moses

Moses is a great figure of moral and social liberation. His role in the Muslim tradition has been as multifaceted as in Judaism and Christianity. This essay attempts to explore his importance in the ideology of radical Islam by exploring Sayyid Qutb's responses to a number of the Moses scenes of the Qur'an in his work Fi zilal al‐qur'an. Qutb's treatment reveals aspects of the ideological structure that informs his writing, his love of Egypt and his spirituality. It shows, also, how he had a vision of Islam that went far beyond the boundaries of a nation state and regarded Nasser as a betrayer of this vision. He saw the Egyptians suffering under him as they had suffered under Pharoah.     

Converging evidence that stereotype threat reduces working memory capacity

Although research has shown that priming negative stereotypes leads to lower performance among stigmatized individuals, little is understood about the cognitive mechanism that accounts for these effects. Three experiments tested the hypothesis that stereotype threat interferes with test performance because it reduces individuals' working memory capacity. Results show that priming self-relevant negative stereotypes reduces women's (Experiment 1) and Latinos' (Experiment 2) working memory capacity. The final study revealed that a reduction in working memory capacity mediates the effect of stereotype threat on women's math performance (Experiment 3). Implications for future research on stereotype threat and working memory are discussed.     

In search of common ground: The Qur'an as literature?

The pluralizing forces in many English speaking countries include a number of Muslim communities. As these become integrated into their host societies, their social and spiritual values, and above all a recognition of the Qur'an as their sacred Book have the potential to enrich the mythic and symbolic resources of English as a language of literature. For this, the Qur'an needs to establish recognition in the first place at a secular level as literature in order to pave the way for an awareness of its spiritual dimensions. This essay outlines some of the obstacles to such a development, and suggests ways in which they may be overcome. It shows how the Qur'an re‐presents in a distinctive way themes and motifs familiar to English readers of the Bible. It offers English renderings of a number of qur'anic pericopes. It attempts by use of a number of techniques to present them in a way that communicates something of the genius of the Qur'an as literature, and thereby to offer a basis on which non‐Muslims can share with Muslims its distinctive contribution to the spiritual heritage of humankind.     

What information underlies correct rejections in short-term recognition memory?

We propose that correct rejections are based on information that contradicts the study set, rather than on insufficient familiarity. Using two-dimensional stimuli, we varied the featural overlap between lures and the study set so that one feature of the lure had occurred during study and the second feature of the lure had not occurred. Familiarity varied with the number of times the studied feature had occurred, whereas detectability of the extralist feature varied with the number of studied alternatives on the same dimension. Lures increased in difficulty with familiarity only when familiarity of the studied feature was confounded with the number of alternatives to the extralist feature. Hence, the difficulty in rejecting the lure was controlled by the number of alternatives to the extralist feature, not by the familiarity of the lure. Current theory requires additional representation assumptions and a new comparison process to accommodate these data.     

Jurors' Use of Instructions on Negligence1

At the end of a trial, the judge gives jurors a set of instructions that explain the laws that are applicable to the case and that direct jurors to reach a verdict in accordance with those laws. Little is known about how well jurors understand instructions in civil cases. We assess the extent to which jurors understand judicial instructions in negligence cases. We address 3 issues: (a) To what extent do they understand these instructions? (b) To what extent is their comprehension enhanced by access to a written copy of the instructions? and (c) What effect does deliberation have on jurors' comprehension levels? Overall comprehension was approximately 64% and access to written instructions did not enhance comprehension, but the opportunity to deliberate did.     

Evaluating the random representation assumption of lexical semantics in cognitive models

A common assumption implicit in cognitive models is that lexical semantics can be approximated by using randomly generated representations to stand in for word meaning. However, the use of random representations contains the hidden assumption that semantic similarity is symmetrically distributed across randomly selected words or between instances within a semantic category. We evaluated this assumption by computing similarity distributions for randomly selected words from a number of well-known semantic measures and comparing them with the distributions from random representations commonly used in cognitive models. The similarity distributions from all semantic measures were positively skewed compared with the symmetric normal distributions assumed by random representations. We discuss potential consequences that this false assumption may have for conclusions drawn from process models that use random representations.     

Applying the permutation test to factorial designs

The permutation test follows directly from the procedure in a comparative experiment, does not depend on a known distribution for error, and is sometimes more sensitive to real effects than are the corresponding parametric tests. Despite its advantages, the permutation test is seldom (if ever) applied to factorial designs because of the computational load that they impose. We propose two methods to limit the computation load. We show, first, that orthogonal contrasts limit the computational load and, second, that when combined with Gill’s (2007) algorithm, the factorial permutation test is both practical and efficient. For within-subjects designs, the factorial permutation test is equivalent to an ANOVA when the latter’s assumptions have been met. For between-subjects designs, the factorial test is conservative.

Stereotype threat and executive resource depletion: examining the influence of emotion regulation

Research shows that stereotype threat reduces performance by diminishing executive resources, but less is known about the psychological processes responsible for these impairments. The authors tested the idea that targets of stereotype threat try to regulate their emotions and that this regulation depletes executive resources, resulting in underperformance. Across 4 experiments, they provide converging evidence that targets of stereotype threat spontaneously attempt to control their expression of anxiety and that such emotion regulation depletes executive resources needed to perform well on tests of cognitive ability. They also demonstrate that providing threatened individuals with a means to effectively cope with negative emotions--by reappraising the situation or the meaning of their anxiety--can restore executive resources and improve test performance. They discuss these results within the framework of an integrated process model of stereotype threat, in which affective and cognitive processes interact to undermine performance.
