The sounds of dominance.

A study was conducted to determine the effects of vocal cues on judgements of dominance in an interpersonal influence context. Physical measures of human vocal cues and participant ratings of dominance were obtained from videotapes of actors delivering short influence messages. After controlling for linguistic and visual content of messages, results indicated that mean amplitude and amplitude standard deviation were positively associated with dominance judgments, whereas speech rate was negatively associated with dominance judgments. An unexpected interaction revealed that mean fundamental frequency (F₀) was positively associated with dominance judgments for male speakers but not significantly associated with dominance judgments for female speakers. F₀ standard deviation was not significantly associated with dominance judgments. Results support the conclusion that dominance judgments are inferred from multiple sources of information and that some vocal markers of dominance are more influential than others.     

Per Capita Alcohol Consumption and Suicide Rates in the U.S., 1950–2002

The aim of this paper was to estimate how suicide rates in the United States are affected by changes in per capita consumption during the postwar period. The analysis included Annual suicide rates and per capita alcohol consumption data (total and beverage specific) for the period 1950–2002. Gender‐ and age‐specific models were estimated using the Box‐Jenkins technique for time series analysis. No significant estimate was found for males. For females the total alcohol estimate (0.059) was significant at the 10% level whereas the spirits estimate was significant with an effect of 0.152. The results imply that a change in U.S. per capita consumption would result in a change in female suicide rates, whereas the male rates would not be affected.     

Late Abrahamic reunion? Religious fundamentalism negatively predicts dual Abrahamic group categorization among Muslims and Christians

Although extensive research has documented the effectiveness of common or dual in‐groups on improving intergroup relations, little is known about how individual‐difference variables affect people's willingness to make such re‐categorizations in the first place. Here, we demonstrate that individual differences in religious fundamentalism predict willingness to categorize in terms of the common Abrahamic religious origins of Christianity and Islam among Christians and Muslims. Study 1 (n = 243 Christians, 291 Muslims) uses multigroup structural equation modeling and Study 2 (n = 80 Christians) an experimental manipulation to show that religious fundamentalism causes lower dual Abrahamic categorization, which, in turn, predicts more positive attitudes toward the respective out‐group, mediating the negative effects of religious fundamentalism on religious intergroup bias. While making the general case that individual differences may play important roles for dual categorizations, these results also highlight the specific positive potential of dual ecumenical categorizations for improving interreligious relations. Research and societal implications are discussed. Copyright © 2014 John Wiley & Sons, Ltd.     

Effects of testing on subsequent re‐encoding and long‐term forgetting of action‐relevant materials: On the influence of recall type

Testing one's memory of previously studied information reduces the rate of forgetting, compared to restudy. However, little is known about how this direct testing effect applies to action phrases (e.g., “wash the car”) – a learning material relevant to everyday memory. As action phrases consist of two different components, a verb (e.g., “wash”) and a noun (e.g., “car”), testing can either be implemented as noun‐cued recall of verbs or verb‐cued recall of nouns, which may differently affect later memory performance. In the present study, we investigated the effect of testing for these two recall types, using verbally encoded action phrases as learning materials. Results showed that repeated study–test practice, compared to repeated study–restudy practice, decreased the forgetting rate across 1 week to a similar degree for both noun‐cued and verb‐cued recall types. However, noun‐cued recall of verbs initiated more new subsequent learning during the first restudy, compared to verb‐cued recall of nouns. The study provides evidence that testing has benefits on both subsequent restudy and long‐term retention of action‐relevant materials, but that these benefits are differently expressed with testing via noun‐cued versus verb‐cued recall.     

Metaphysics Within Science: Against Radical Naturalism

In Every Thing Must Go James Ladyman and Don Ross argue for a radical version of naturalistic metaphysics and propose that contemporary analytic metaphysics is detached from science and should be discontinued. The present article addresses the issues of whether (i) science and metaphysics are separable, (ii) intuitions and understanding should be excluded from scientific theory, and (iii) Ontic Structural Realism satisfies the criteria of the radical version of naturalism advanced by Ladyman and Ross. The point underlying those topics is that successful scientific research presupposes metaphysics, and that basic epistemic virtues common to metaphysics and science may allow us—as opposed to what Ladyman and Ross suggest—to increase our understanding of the world and to put constraints on allowable metaphysical theories.     

Rousseau on Sex-Roles,Education and Happiness

Over the last decade, philosophers of education have begun taking a renewed interest in Rousseau’s educational thought. This is a welcome development as his ideas are rich with educational insights. His philosophy is not without its flaws, however. One significant flaw is his educational project for females, which is sexist in the highest degree. Rousseau argues that females should be taught to “please men…and make [men’s] lives agreeable and sweet.” The question becomes how could Rousseau make such strident claims, especially in light of his far more insightful ideas concerning the education of males. This paper attempts to make sense of Rousseau’s ideas on the education of females. While I maintain that Rousseau’s project for Sophie ought to be rejected, I argue that we should try to understand how this otherwise insightful thinker could make such surprising claims. Is it a bizarre inconsistency in his philosophical reasoning or an expression of his unabashed misogyny, as so many have claimed? I argue that it is neither. Rather, it is a product of his conception of human happiness and his belief in the irreducible role human sexual relations has in achieving and prolonging that happiness. For Rousseau, sex, love and happiness are inextricably connected, and he believes that men and women will be happiest when they inhabit certain sex roles—not because sex roles are valuable in themselves, but because only through them can either men or women hope to be happy.
