The Journal of Sexual Medicine. Volume 15, Issue 9, September 2018, Pages 1322-1335. https://doi.org/10.1016/j.jsxm.2018.07.015
Abstract
Introduction: The actual definitions of paraphilic thoughts or behaviors and hypersexuality are still a matter of debate in the scientific community, and few studies have evaluated their psychopathological correlates in non-clinical samples of both men and women.
Aim: This study aimed at shedding light on the gender differences in terms of frequency of paraphilic fantasies and behaviors, and the relationship among paraphilias, hypersexuality, and general psychopathology.
Methods: A sample of 775 university students (243 men, 532 women) was recruited from 6 Italian universities using questionnaires posted in social networks. Paraphilic behaviors, fantasies, and masturbation during these fantasies were evaluated, as well as hypersexuality, psychopathological correlates, self-perceived gender identity, and a history of adverse childhood conditions.
Main Outcome Measures: Participants were assessed on the presence of paraphilic fantasies, behaviors, and masturbation related to paraphilic thoughts, and evaluated by means of the Symptom Checklist 90-Revised, the Hypersexual Disorder Screening Inventory, the International Index of Erectile Function, the Female Sexual Function Index, the Gender Identity/Gender Dysphoria Questionnaire, and the Childhood Experience of Care and Abuse Questionnaire.
Results: In the present survey, 50.6% of the men and 41.5% of the women reported at least 1 behavior considered paraphilic. A gender difference in the prevalence of the main paraphilic interests and behaviors was observed, with men reporting a higher prevalence of voyeurism, exhibitionism, sadism, and frotteurism, and a higher prevalence of fetishism and masochism in women. Both general psychopathology and sexual dysfunctions were associated with hypersexuality, rather than with the content of sexual fantasies. Finally, an association between childhood adversities and hypersexuality was found in women but not in men.
Clinical Implications: Understanding the psychopathological correlates of paraphilic fantasies/behaviors and hypersexuality may allow clinicians to develop specific psychological and pharmacological interventions.
Strengths & Limitations: This is one of the few studies assessing paraphilic phenomenology and psychopathological correlates of hypersexuality in a non-clinical sample of both men and women.
Conclusion: The results seem to demonstrate that paraphilic thoughts and behaviors are not really a deviation from normalcy, rather they are quite widespread in the young population, and the distinction between healthy and pathological sexual interests may be better replaced by an all-encompassing approach considering ego-dystonic sexuality, hypersexuality, and their psychopathological correlates.

The First-Daughter Effect: The Impact of Fathering Daughters on Men’s Preferences for Gender-Equality Policies
The First-Daughter Effect: The Impact of Fathering Daughters on Men’s Preferences for Gender-Equality Policies. Elizabeth A Sharrow, Jesse H Rhodes, Tatishe M Nteta, Jill S Greenlee. Public Opinion Quarterly, https://doi.org/10.1093/poq/nfy037
Abstract: An extensive literature on the politics of the family suggests that familial relationships play a central role in individuals’ political socialization and can ultimately shape one’s policy preferences. A current debate within this literature deals with the impact of daughters on fathers’ political attitudes. In this article, we address this debate in relation to a specific set of policy preferences and ask: Does the experience of fathering daughters affect men’s opinions toward gender-equality policies? In addressing this question, this study examines three theoretically motivated propositions: first, that having a daughter leads men to see the benefits of and support public policies that aim to reduce gender inequality; second, that fathers with a larger proportion of daughters express stronger support for these policies; and finally, that having a daughter as a man’s first child is a critical event in the political socialization of men, such that this experience of “first-daughterhood” will lead to higher levels of support for gender-equality policies. We use original representative survey data from a module on the 2016 Cooperative Congressional Election Study (CCES) to test these three hypotheses. The results of our analyses suggest that the experience of having a daughter as a first child—but not the effect of having a daughter in general nor the experience of fathering a higher proportion of daughters—significantly increases fathers’ support for policies designed to increase gender equality.

Confirmation bias theory of salience: consumers tend to disregard information (like a tax) that does not align with their intention to purchase an item, and this lack of alignment increases in the size of the tax
Naomi Feldman, Jacob Goldin, and Tatiana Homonoff (2018), Raising the Stakes: Experimental Evidence on the Endogeneity of Taxpayer Mistakes, National Tax Journal, 71:2, pp. 201-230. DOI: doi.org/10.17310/ntj.2018.2.01
Abstract: Recent evidence suggests consumers fail to account for taxes that are excluded from a good's displayed price. What is less understood is whether and how such "salience effects" depend on the magnitude of the tax. We conduct a laboratory shopping experiment with real stakes to study the effect of tax size on salience. We find no evidence that salience effects decline as the tax rate increases; we document a statistically significant salience effect at a tax rate that is considerably larger than the tax rates at which such effects have been previously documented. In fact, our results are more consistent with the hypothesis that higher taxes make consumers less attentive (at least for the range of taxes we consider). This result can be explained by a confirmation bias theory of salience: consumers tend to disregard information (like a tax) that does not align with their intention to purchase an item, and this lack of alignment increases in the size of the tax

Gender-Based Occupational Segregation and Sex Differences in Sensory, Motor, and Spatial Aptitudes
Gender-Based Occupational Segregation and Sex Differences in Sensory, Motor, and Spatial Aptitudes. Michael Baker, Kirsten Cornelson. Demography, https://link.springer.com/article/10.1007/s13524-018-0706-3
Abstract: Research on sex differences in humans documents gender differences in sensory, motor, and spatial aptitudes. These aptitudes, as captured by Dictionary of Occupational Titles (DOT) codes, predict the occupational choices of men and women in the directions indicated by this research. We simulate that eliminating selection on these skills reduces the Duncan index of gender-based occupational segregation by 20 % to 23 % in 1970 and 2012, respectively. Eliminating selection on DOT variables capturing other accounts of this segregation has a smaller impact.

The psychology of vegetarianism: Recent advances and future directions
The psychology of vegetarianism: Recent advances and future directions. Daniel L. Rosenfeld. Appetite, https://doi.org/10.1016/j.appet.2018.09.011
Abstract: Whereas vegetarianism has long garnered attention from nutritional science and philosophy, psychological research exploring this eating behavior has emerged only in the past few decades. Six years ago, Ruby (2012) reviewed the extant literature on the psychology of vegetarianism, showcasing its promise as “a blossoming field of study.” In the time since, this line of research truly has blossomed, as subsequent work has addressed prior knowledge gaps and initiated new lines of inquiry. While evidence on previously studied topics of dietary motivation, moral values, gender, differences between vegetarians and vegans, barriers to dietary change, and disordered eating has continued to expand, new lines of research on identity, social experiences, flexitarianism, culture, and prospective vegetarianism have emerged. Recent psychometric advancements, moreover, have constructed useful measures to assess relevant constructs. The current review synthesizes this amalgam of research, identifying emergent themes and highlighting promising directions for future inquiry.

What people prefer and what they think they prefer in short- and long-term partners: The effects of the menstrual cycle phase, hormonal contraception, pregnancy, and the marital and the parenthood status on partner preferences
What people prefer and what they think they prefer in short- and long-term partners. The effects of the phase of the menstrual cycle, hormonal contraception, pregnancy, and the marital and the parenthood status on partner preferences. Jaroslav Flegr et al. Evolution and Human Behavior, https://doi.org/10.1016/j.evolhumbehav.2018.09.003
Abstract: The issue with most studies concerned with mate selection preferences in humans is that they rely on declarations and rational actions of experimental subjects, which are affected by their pre-conceived opinions and prejudices. Moreover, current research suggests that subcortical structures and processes, rather than the neocortex, play the principal role in actual partner choice behaviour. Consequently, we have only limited information on how relevant our current knowledge is in relation to real-life human ethology. To address these issues, we surveyed 2718 women and 4073 men between the ages of 16–50 and compared their declared and observed preferences for various properties in short-term and long-term partners. We found differences between what the subjects declared to prefer and what they preferred in reality: for example, men declared that wealth was the second least desirable property out of eleven in short-term partners, but we observed that in reality, they considered wealth the third most important factor after charisma and sense of humour. Similarly, while women declared that dominance and masculinity were desirable properties in short-term partners, in the observational part of the study, they showed little preference for these traits. Furthermore, we investigated the effects of the phase of the menstrual cycle, hormonal contraception, pregnancy, and partnership and parenthood status on these preferences. We found some support for the good parents hypothesis and no support for the good genes and the immunocompetence handicap hypotheses when observed, rather than declared preferences were considered. We also detected that hormonal contraception, and parenthood and partnership status influenced declared preferences in considerable ways, but had only a small, if any, impact on observed preferences. We suggest interpreting the results of studies reliant on declarations and rational actions of experimental subjects with great caution.

First detect gender, then attractiveness: Attractiveness follows gender in terms of underlying neural processes; early face attractiveness assessment seems to rely on gender-stereotypes
First gender, then attractiveness: Indications of gender-specific attractiveness processing via ERP onsets. Claus-Christian Carbon e al. Neuroscience Letters
https://doi.org/10.1016/j.neulet.2018.09.009
Highlights
• Facial gender and attractiveness: Key features to study face processes.
• Processing onsets estimated by LRP- and N200-effects.
• Attractiveness follows gender in terms of underlying neural processes.
• Early face attractiveness assessment seems to rely on gender-stereotypes.
• Used paradigm is promising to further uncover the time course of face perception.
Abstract: We followed an ERP-based approach to gain knowledge on the dependence and temporal order of two essential processes of face perception: attractiveness and gender. By combining a dual-choice task with a go/nogo-paradigm focusing on the LRP and N200-effect, we could estimate the processing times and onsets of both types of face processing. The analyses of the LRP revealed that gender aspects were processed much earlier than attractiveness. Whereas gender was already analysed 243.9 ms post-stimulus onset, attractiveness came into play 58.6 ms later, i.e. after a post-stimulus onset delay of 302.5 ms. This resulting pattern was mirrored by the analyses of the N200-effect, an effect available mainly frontally which is supposed to correlate with the inhibition of inappropriate responses. Taking the onset of the N200 effect as an estimator for the moment at which information has been processed sufficiently for task decision, we could trace the N200 effect at 152.0 ms for go/nogo-decision on gender, while not as early as 206.7 ms on attractiveness. In sum, processing of facial attractiveness seems to be based on gender-specific aesthetic pre-processing, for instance via activating gender-specific attractiveness prototypes which show focused processing of certain facial aspects.

From 2017: Female Waist-to-Hip Ratio (WHR) is correlated to divorce frequency
Chiappa, P., & Singh, S. (2017). Sexual dimorphism in waist-to-hip ratio and divorce frequency in human populations. Evolutionary Behavioral Sciences, 11(3), 221-241. http://dx.doi.org/10.1037/ebs0000100
Abstract: The current study tests a series of evolutionary predictions about the changing opportunities for human male mate choice and female Waist-to-Hip Ratio (WHR) across populations. We predicted that the divorce frequency (that we used as a reflection of the frequency of male mate choice) would be positively correlated with sexual dimorphism in WHRs across human populations. With published data, we built 2 samples, 1 at the international level and the other at the national level. The results showed that sexual dimorphism in WHR is positively correlated with the divorce-to-married ratio in 68 countries worldwide, as well as in the 32 Mexican states. Taken together, our results suggest that the opportunity for human male mate choice, based on female WHR, varies among human populations. We discuss the possibility of connecting this variation to human diversity in divorce practices. We conclude that human male mate choice is a circumstantially conditioned selective process responsible for such dimorphism and suggest that cultural and social aspects are potentially powerful in examining the factors capable of strengthening or weakening the selective process.
