Assessing the relationship between cold pressor pain responses and dimensions of the anxiety sensitivity profile in healthy men and women

Anxiety sensitivity (AS) has been shown previously to be an important factor in the perception and experience of experimentally induced pain within healthy adults. The aim of the current study was to extend this research by: (i) using the Anxiety Sensitivity Profile (ASP) as an alternative measure of AS; (ii) examining whether different coping instructions affect pain reports; and (iii) investigating potential differences between men and women. Participants were 50 healthy adults (23 males, 27 females) who were required to complete 2 versions of the cold pressor pain task; one version required the use of control instructions, whereas the other made use of acceptance-based instructions. Although the coping instructions were found to affect pain thresholds (acceptance resulted in lower thresholds), a similar pattern of correlations were found between the pain indexes and AS under both conditions. Of the ASP subscales, the gastrointestinal and cognitive concerns components were found to be the most strongly related to pain experiences. When the analysis was conducted separately for each sex, the ASP scales were related to the self-report measures of pain in women, whereas they were related to the behavioural measures of pain in men. These results not only confirm that AS is associated with experimental pain, but that there may be sex differences in this relationship.     

Androgen mediation of conditioned rhythmic cloacal sphincter movements in Japanese Quail (Coturnix japonica)

Demonstrations of increased reproductive success due to sexual conditioning in Japanese quail (Coturnix japonica) have been reported, although the mechanisms that underlie these effects have remained elusive. One possible mechanism is conditioned rhythmic cloacal sphincter movements (RCSM). Two experiments were conducted with male quail to determine whether associations between a conditioned stimulus (CS) and a hen would result in the ability of the CS to elicit RCSM, and to explore the androgen mediation of conditioned RCSM. The results suggest that a focal CS paired with visual access to a female will elicit RCSM via a representation of the hen activated by the CS. Further, the available evidence indicates that conditioned RCSM is androgen mediated and that this learning may transfer across breeding seasons.     

Incremental validity in the psychological assessment of children and adolescents

Incremental validity in the process of psychological assessment of children and adolescents is explored. The authors highlight the dependence of the incremental validity of assessment information on factors such as goal of assessment, other information available, base rate of the problem or outcome, age or gender of the child, and type of problem being assessed. The authors discuss the incremental validity of assessment information from alternate sources, methods, and constructs. In view of the limited number of studies directly relevant to incremental validity in child clinical assessments, the authors call for more clinically relevant research. To have the greatest impact on child and adolescent services, this research must be readily generalized and immediately relevant to actual clinical practice.     

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.     

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.     

“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.     

Use them or lose them: Are manipulatives needed to assess numeracy and geometry performance in preschool?

In two studies, we investigated whether using three-dimensional (3D) manipulatives during assessment aided performance on a variety of preschool mathematics tasks compared to pictorial representations. On measures of children's understanding of counting and cardinality (n = 103), there was no difference in performance between manipulatives and pictures, with Bayes factors suggesting moderate evidence in favor of the null hypothesis. On a measure of children's shape identification (n = 93), there was no difference in performance between objects and pictures, with Bayes factors suggesting moderate evidence in favor of the null hypothesis. These results suggest flexibility in the materials that can be used during assessment. Pictures, or 2D renderings of 3D objects, which can be easily printed and reproduced, may be sufficient for assessing counting and shape knowledge without the need for more cumbersome concrete manipulatives.     

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.     

Partial knowledge in the development of number word understanding

A common measure of number word understanding is the give‐N task. Traditionally, to receive credit for understanding a number, N, children must understand that N does not apply to other set sizes (e.g. a child who gives three when asked for ‘three’ but also when asked for ‘four’ would not be credited with knowing ‘three’). However, it is possible that children who correctly provide the set size directly above their knower level but also provide that number for other number words (‘N + 1 givers’) may be in a partial, transitional knowledge state. In an integrative analysis including 191 preschoolers, subset knowers who correctly gave N + 1 at pretest performed better at posttest than did those who did not correctly give N + 1. This performance was not reflective of ‘full’ knowledge of N + 1, as N + 1 givers performed worse than traditionally coded knowers of that set size on separate measures of number word understanding within a given timepoint. Results support the idea of graded representations (Munakata, Trends in Cognitive Sciences, 5, 309–315, 2001.) in number word development and suggest traditional approaches to coding the give‐N task may not completely capture children's knowledge.
