Show and prove: investigating differences in the self-beliefs of Black and White honor students

While there is great deal of research that tracks self-regulatory academic beliefs and behaviors of students, relatively few efforts examine the specific self-beliefs of high achieving African American students. This study compared the intelligence-related beliefs, efficacy beliefs and academic goal orientations of 257 African American (N = 196) and White (N = 61) sophomore and senior students from among honors-level language arts classes in three large midwestern high schools. The results of this study suggest that while African American students and their White peers do not significantly differ with respect to efficacy beliefs or goal orientation, African American students expressed more strongly-held beliefs that were consistent with an entity view of intelligence than did White students. The implications of these results are discussed, as well as a practical means of application for academic settings.     

Latent inhibition in the honey bee, Apis mellifera: Is it a unitary phenomenon?

Latent inhibition refers to learning that some stimuli are not signals of important events. It has been widely studied in vertebrates, but it has been substantially less well studied in invertebrates. We present an investigation into latent inhibition in the honey bee (Apis mellifera) using a proboscis extension response conditioning procedure that involved ‘preexposure’ of an odor without reinforcement prior to appetitive conditioning. A significant latent inhibition effect, measured in terms of a reduction in acquisition performance to the preexposed odor, was observed after 8 unreinforced presentations, and the effect continued to increase in strength up to 30 presentations. We also observed that memories formed for the preexposed odor lasted at least 24 h. Further manipulation of interstimulus interval and the visual conditioning context partially attenuated the effect. The latter results indicate that latent inhibition in honey bees may not be a unitary phenomenon. Two different mechanisms may be required, in which one mechanism is dependent on the visual context and the second is not.     

Reaching around barriers: the performance of the great apes and 3–5-year-old children

Inhibitory control has been suggested as a key predictive measure of problem-solving skills in human and nonhuman animals. However, there has yet to be a direct comparison of the inhibitory skills of the nonhuman apes and their development in human children. We compared the inhibitory skills of all great ape species, including 3–5-year-old children in a detour-reaching task, which required subjects to avoid reaching directly for food and instead use an indirect reaching method to successfully obtain the food. We tested 22 chimpanzees, 18 bonobos, 18 orangutans, 6 gorillas and 42 children. Our sample included chimpanzees, bonobos and orangutans housed in zoos (N = 27) and others housed in sanctuaries in their native habitats (N = 37). Overall, orangutans were the most skilful apes, including human children. As expected older children outperformed younger children. Sanctuary chimpanzees and bonobos outperformed their zoo counterparts whereas there was no difference between the two orangutan samples. Most zoo chimpanzees and bonobos failed to solve the original task, but improved their performance with additional training, although the training method determined to a considerable extent the level of success that the apes achieved in a transfer phase. In general, the performance of the older children was far from perfect and comparable to some of the nonhuman apes tested.     

UNIVERSALS, THE ESSENTIAL PROBLEM AND CATEGORICAL PROPERTIES

There are three outstanding issues raised by my critics in this volume. The first concerns the nature and status of universals (John Heil). The second is ‘the essential problem’, which is the issue of how to distinguish the essential properties of natural kinds from their accidental ones, and the related question of whether we really need to believe in the essences of natural kinds (Stephen Mumford). The third is that of strong versus weak dispositional essentialism (Alexander Bird), or equivalently, whether there is any place for categorical properties in an essentialist metaphysic (John Heil). This paper addresses these three issues.     

What shields some can shackle others: the approach‐related consequences of threat categorisations vary by agreeableness

It is common to think that threat categorisation tendencies (TCTs) should undermine a person's subjective well‐being. However, recent research has suggested that the hedonic impact of such tendencies varies considerably according to a person's traits. The present research seeks to extend such a perspective by considering potential interactions between TCTs and the trait of agreeableness. TCTs were measured through the use of choice reaction time tasks contrasting the threat and non‐threat categories. As expected, TCTs were not correlated with the trait of agreeableness, but interacted with this trait in predicting the dependent measures. Within three studies involving 184 undergraduates, TCTs were associated with the higher levels of approach‐related behaviour and positive emotion among disagreeable individuals, but lower levels of these same variables among agreeable individuals. The authors suggest that threat categorisation tendencies psychologically protect or burden the individual, depending on the levels of agreeableness. Copyright © 2005 John Wiley & Sons, Ltd.     

Regional Patterns of Religious Affiliation and Availability of Complementary and Alternative Medicine

Complementary and alternative medicines (CAMs) retain an enduring popularity in spite of the fact that there is poor evidence of their efficacy. Public attraction toward CAM may be based, in part, on a public appetite for mysticism; in many countries, increases in interest in CAM may in turn result from decreasing social acceptance of participation in formal religions. The present study examined patterns of CAM availability and self-declared religious affiliation across 30 geographical regions in Ireland. After controlling for differences in population, the data show a statistically significant inverse correlation between CAM availability and religious affiliation. Implications are discussed. Brian M.

Relations Among Milk and Non-Milk Beverage Consumption, Calcium, and Relative Weight in High-Weight Status Children

Relations among weight, calcium, and milk have received considerable attention, but inconsistencies remain regarding strength and direction of associations. Calcium, milk, other beverages, and weight status associations were examined among children >75th BMI percentile from three studies. Results indicated negative relations between z-BMI and non-whole milk and calcium in one sample, with lower z-BMI and percent body fat among older children drinking any non-whole milk. In one older child sample, z-BMI and percent body fat were higher for whole milk consumers. The only significant relation observed for other beverages was the negative association between juice and percent body fat in younger children. Milk, calcium, and child weight status associations are inconsistent, and appear dependent on milk type and child age.     

Secularism,Criticism, and Religious Studies Pedagogy

Abstract. Secularization, the idea that religion would gradually diminish over time, was once widely assumed to be true by scholars of religion, but the unexpected resurgence of religious traditions has called it into question. Related debates on the distinction between religion and the secular have destabilized religious studies further. What does the crisis of secularization and secularism mean for the religious studies classroom? This essay proposes a model of religious criticism in the wake of secularism. No longer simply claiming a “view from nowhere,” students and instructors can (by observing standards of evidence, reason, and self‐disclosure) combine criticism with learning. Drawn from aesthetic and ethical traditions of criticism, religious criticism can be practiced by “teaching the conflicts” and through the pedagogical models of Freire and hooks.     

Disadvantaged by Diversity? The Effects of Diversity Goals on Competence Perceptions1

This research examined how efforts to ensure demographic diversity in a work group affected perceptions of the competence of individuals who are likely targets of such efforts. In three experiments, 262 undergraduates gave their impressions and performance expectations of members of a group assembled to work on a task. When a diversity rationale rather than a merit rationale was provided for how the work group was assembled, both women (Studies 1 and 2) and Black men (Study 3) were perceived as less competent and were expected to be less influential. This effect occurred regardless of the proportional representation of women or the degree of the groups' heterogeneity. The diversity rationale also produced more negative characterizations than did another non‐merit‐based rationale: scheduling convenience.
