Universal sex differences in the desire for sexual variety: tests from 52 nations, 6 continents,and 13 islands

Evolutionary psychologists have hypothesized that men and women possess both long-term and short-term mating strategies, with men's short-term strategy differentially rooted in the desire for sexual variety. In this article, findings from a cross-cultural survey of 16,288 people across 10 major world regions (including North America, South America, Western Europe, Eastern Europe, Southern Europe, Middle East, Africa, Oceania, South/Southeast Asia, and East Asia) demonstrate that sex differences in the desire for sexual variety are culturally universal throughout these world regions. Sex differences were evident regardless of whether mean, median, distributional, or categorical indexes of sexual differentiation were evaluated. Sex differences were evident regardless of the measures used to evaluate them. Among contemporary theories of human mating, pluralistic approaches that hypothesize sex differences in the evolved design of short-term mating provide the most compelling account of these robust empirical findings.     

Hypnosis and clinical pain

Hypnosis has been demonstrated to reduce analogue pain, and studies on the mechanisms of laboratory pain reduction have provided useful applications to clinical populations. Studies showing central nervous system activity during hypnotic procedures offer preliminary information concerning possible physiological mechanisms of hypnotic analgesia. Randomized controlled studies with clinical populations indicate that hypnosis has a reliable and significant impact on acute procedural pain and chronic pain conditions. Methodological issues of this body of research are discussed, as are methods to better integrate hypnosis into comprehensive pain treatment.     

Neuronal unit activity in the abducens nucleus during classical conditioning of the nictitating membrane response in the rabbit (Oryctolagus cuniculus).

Neuronal unit activity was recorded from the abducens (6th nerve) nucleus, the "final common path," during classical conditioning of the nictitating membrane (NM) response in the rabbit, with the use of a tone conditioned stimulus, an air puff unconditioned stimulus (UCS), 250-msec interstimulus interval, and 60-sec intertrial interval. Animals were given 2 days of conditioning training (104 trials in eight blocks per day) and 1 day of extinction. Control animals were given comparable periods of stimulus presentations, explicitly unpaired. Activity of small clusters of units--"multiple unit" recording--was compared with the amplitude-time course of the NM response. Between-blocks comparisons of neural and behavioral responses indicated an essentially perfect correlation during acquisition of the conditioned response (Day 1, r = .99; Day 2, r = .98) and a slightly lower correlation during extinction (r = .93) for the conditioning animals. Within-blocks comparisons indicated a close correspondence between the histograms of unit activity and the amplitude-time course of the NM response for the conditioning animals in all phase of training and for the control animals in the UCS trial blocks.     

Effects of initial success or failure in a stressful or relaxed environment on subsequent task performance

Forty male and 40 female undergraduate subjects worked on anagram problems in either a stressful or a relaxed environment after having experienced either success or failure on a similar task. Internal arousal, which was expected to be minimal following success in a relaxed setting and maximal following failure in the stressful environment, was assumed to bear an inverted U-shaped relation to performance. Consistent with the implications of these assumptions, achievement in a stressful setting was lower following initial failure than following initial success, while initial failure in a relaxed environment facilitated subsequent performance. The interpretation of these results was supported by the effects of the experimental variables on indirect measures of arousal as well as by the relationship between direct measures of arousal and task performance. In addition, the achievement of female subjects tended to be facilitated by failure while the performance of males was consistently debilitated by it.     

Children's perception of media-portrayed sex roles

The immediate impact on preschool and elementary school children of a televised presentation in which the traditional sex roles of physician and nurse were reversed was examined. After viewing a videotape of a male nurse and a female physician, subjects were asked to identify photographs or names of the physician and nurse. Preschool, first-, and fourth-grade children selected male names or pictures for the physician and female names or pictures for the nurse, thereby reversing genders. Their immediate recall appeared strongly influenced by their stereotypes rather than by the film they had just viewed. Seventh-grade children correctly identified the names of the physician and nurse.The authors wish to thank Dr. Edward F. Meydrech, Assistant Professor, Department of Preventive Medicine and Chief of the Division of Biostatistics, University of Mississippi Medical Center, for his invaluable assistance in the analysis of the data.     

“Nature and Society Give Women a Great Habit of Suffering”: Germaine de Staël's Feminism and Its Challenges

Germaine de Staël (1766–1817), despite having published a considerable body of work, is seldom regarded as a feminist philosopher. Unlike, for instance, Mary Wollstonecraft of the same period, Staël is not directly arguing for the equality of the sexes. She even, at times, makes surprisingly derogatory remarks about women's nature. I argue that she is nevertheless putting forward a brand of difference feminism, which deserves our attention as a contribution to feminist reflections on gender norms in the early modern era. Staël's contribution takes the form of a plea for the improvement of women's lives that engages with the combined action of nature and society. I clarify the meaning that we should ascribe to Staël's frequent appeals to nature and argue that, for her, society and education should be used to correct (alleged) natural weaknesses instead of reinforcing them. I also give an overview of Staël's political proposals toward the improvement of women's lives, which call for a better form of political regime than the one she lived in, as well as a better access to education and a more egalitarian conception of marriage.     

Perceived mattering in stepfamilies: A social relations model analysis

The current study examined the respective role of stepfamily members' individual characteristics and their dyadic relationships in stepfamily members' perceptions of mattering to one another. Parents, stepparents, and adolescents from 86 stepfamilies participated. Applying social relations model analyses, several trends emerged regarding the relative importance of individual and dyadic factors. Parents' and adolescents' reports of mattering to one another were mainly driven by individual factors, whereas relational factors were important to understand the reports of mattering in which the stepparent was one of the dyad members. These findings contribute to stepfamily research by highlighting that stepfamily members' sense of belonging is at least partly a function of the interpersonal adaptation between the stepparent and other family members.
