Women are still underrepresented in engineering courses although some German universities offer separate women’s engineering courses which include virtual STEM learning environments. To outline information about fundamental aspects relevant for virtual STEM learning, one has to reveal which similarities both genders in virtual learning show. Moreover, the question arises as to whether there are in fact differences in the virtual science learning of female and male learners. Working with virtual STEM learning environments requires strategic and arithmetic-operative competences. Even if we (...) assume that female and male learners have similar competences levels, their correlational pattern of competences, motivational variables, and invested effort during virtual STEM learning might differ. If such gender differences in the correlations between cognitive and motivational variables and learning behavior were revealed, it would be possible to finetune study conditions for female students in a separate engineering course and shape virtual STEM learning in a more gender-appropriate manner. That might support an increase in the number of women in engineering courses. To reveal the differences and similarities between female and male learners, a field study was conducted with 56 students (female = 27, male = 29) as part of the Open MINT Labs project (the German term for Open STEM Labs, OML). The participants had to complete a virtual STEM learning environment during their regular scie... (shrink)

This study provides a survey of phenomena that present themselves during moments of naturally occurring inner experience. In our previous studies using Descriptive Experience Sampling we have discovered five frequently occurring phenomena—inner speech, inner seeing, unsymbolized thinking, feelings, and sensory awareness. Here we quantify the relative frequency of these phenomena. We used DES to describe 10 randomly identified moments of inner experience from each of 30 participants selected from a stratified sample of college students. We found that each of the (...) five phenomena occurred in approximately one quarter of sampled moments, that the frequency of these phenomena varied widely across individuals, that there were no significant gender differences in the relative frequencies of these phenomena, and that higher frequencies of inner speech were associated with lower levels of psychological distress.

Humans naturally perceive visual patterns in a global manner and are remarkably capable of extracting object shapes based on properties such as proximity, closure, symmetry, and good continuation. Notwithstanding the role of these properties in perceptual grouping, studies highlighted differences in disembedding performance across individuals, which are summarized by the field dependence dimension. Evidence suggests that age and educational attainment explain part of this variability, whereas the role of sex is still highly debated. Also, which stimulus features primarily influence inter-individual (...) variations in perceptual grouping has still to be fully determined. Building upon these premises, we assessed the role of age, education level, and sex on performance at the Leuven Embedded Figure Test—a proxy of disembedding abilities—in 391 cisgender individuals. We also investigated to what extent shape symmetry, closure, complexity, and continuation relate to task accuracy. Overall, target asymmetry, closure, and good continuation with the embedding context increase task difficulty. Simpler shapes are more difficult to detect than those with more lines, yet context complexity impairs the recognition of complex targets to a greater extent. Concerning demographic data, we confirm that age and educational attainment are significantly associated with disembedding abilities and reveal a perceptual advantage in males. In summary, our study further highlights the role of shape properties in disembedding performance and unveils sex differences not reported so far. (shrink)

Hearing loss has been identified as a major modifiable risk factors for dementia. Adult candidates for cochlear implantation represent a population at risk of hearing loss-associated cognitive decline. This study investigated the effect of demographics, habits, and medical and psychological risk factors on cognition within such a cohort. Data from 34 consecutive adults with post-lingual deafness scheduled for CI were analyzed. Pure tone audiometry and Speech Discrimination Score were recorded. The Repeatable Battery for Assessment of Neuropsychological Status for Hearing impaired (...) individuals was used to measure cognition. Demographics, habits, and medical factors were evaluated. Depression was measured using the Hospital Anxiety and Depression Scale, and social inhibition with the Type D questionnaire. All participants suffered from severe to profound hearing loss. The mean RBANS-H total score was 83 ± 16. Participants reported a mean of years of formal education of 12 ± 5 years. The prevalence of habits and medical risk factors was: physical inactivity, body mass index >30, traumatic brain injury, hypertension, heavy alcohol consumption, smoking, and diabetes. Regarding psychological factors, the mean scores of social inhibition and depression were 10 ± 6 and 6 ± 5, respectively. The number of years of education was significantly correlated with the RBANS-H total score, and with the domains “Immediate memory”, “Visuospatial/constructional”, and “Attention”. The mean RBANS-H total score in participants who had university studies or higher level was 97 ± 9, with the remaining participants reporting a mean score of 75 ± 15. Men performed better in the “Visuospatial/constructional”. Physical inactivity was associated with lower scores in the “Delayed memory” ; hypertension correlated with lower RBANS-H total scores and “Attention”. Depression and social inhibition were negatively correlated with RBANS-H total score and with the “Immediate memory,” “Visuospatial/constructional,” and “Attention”. In adults with late-onset deafness scheduled to CI, educational level has a significant effect. Additionally, sex, physical inactivity, hypertension, and psychological traits of social inhibition and depression may also influence cognitive status. Long-term studies with more participants would enable us better understand the effects different risk factors on cognitive status. (shrink)

Animal models are used in experiments in the behavioural neurosciences that aim to contribute to the prevention and treatment of cognitive and affective disorders in human beings, such as anxiety and depression. Ironically, those animals that are likely to be the best models for psychopathology are also likely to be considered the ones that are most morally problematic to use, if it seems probable that (and if indeed they are initially selected as models because) they have experiences that are similar (...) to human experiences that we have strong reasons to avoid causing, and indeed aim to alleviate (such as pain, anxiety or sadness). In this paper, against the background of contemporary discussions in animal ethics and the philosophy of animal minds, we discuss the views that it is morally permissible to use animals in these kinds of experiments, and that it is better to use less cognitively complex animals (such as zebrafish) than more complex animals (such as dogs). First, we criticise some justifications for the claim that human beings and more complex animals have higher moral status. We argue that contemporary approaches that attribute equal moral status to all beings that are capable of conscious strivings (e.g. avoiding pain and anxiety; aiming to eat and play) are based on more plausible assumptions. Second, we argue that it is problematic to assume that less cognitively complex animals have a lesser sensory and emotional experience than more complex beings across the board. In specific cases, there might be good reasons to assume that more complex beings would be harmed more by a specific physical or environmental intervention, but it might also be that they sometimes are harmed less because of a better ability to cope. Determining whether a specific experiment is justified is therefore a complex issue. Our aim in this chapter is to stimulate further reflection on these common assumptions behind the use of animal models for psychopathologies. In order to be able to draw more definite conclusions, more research will have to be done on the influence of cognitive complexity on the experience of (human and non-human) animals. (shrink)

Stereotype threat is a possible reason for difficulties faced by girls and women in the fields of science, technology, engineering, and mathematics. The threat experienced due to gender can cause elevated worry during performance situations. That is, if the stereotype that women are not as good as men in math becomes salient, this stereotype activation draws women’s attention to task-irrelevant worry caused by the fear of conforming to the negative stereotype. Increased worry can reduce cognitive resources, potentially leading to performance (...) decrements. We argue that such worry is more pronounced immediately after an unrelated self-control demand, which is assumed to temporarily decrease people’s self-control exertion over their attention and stream of thought. This prediction was examined in an experiment conducted with 102 participating university students enrolled in courses in which math plays a crucial role. After the manipulation of self-control capacity, stereotype threat was induced for the female students, but not the male students. Then, the students were asked to report their thoughts during a math performance situation three times. Multiple-group autoregressive path models revealed that when self-control capacity was relatively low, female compared with male students reported more intense worry in the initial two thought protocols. In contrast, in the relatively high self-control capacity condition, female and male students did not differ significantly in their reported worry at any time. These results expand on previous findings, suggesting that threat effects depend on definable situational self-control conditions. (shrink)

Many male traits are well explained by sexual selection theory as adaptations to mating competition and mate choice, whereas no unifying theory explains traits expressed more in females. Anne Campbell's “staying alive” theory proposed that human females produce stronger self-protective reactions than males to aggressive threats because self-protection tends to have higher fitness value for females than males. We examined whether Campbell's theory has more general applicability by considering whether human females respond with greater self-protectiveness than males to other threats (...) beyond aggression. We searched the literature for physiological, behavioral, and emotional responses to major physical and social threats, and found consistent support for females' responding with greater self-protectiveness than males. Females mount stronger immune responses to many pathogens; experience a lower threshold to detect, and lesser tolerance of, pain; awaken more frequently at night; express greater concern about physically dangerous stimuli; exert more effort to avoid social conflicts; exhibit a personality style more focused on life's dangers; react to threats with greater fear, disgust, and sadness; and develop more threat-based clinical conditions than males. Our findings suggest that in relation to threat, human females have relatively heightened protective reactions compared to males. The pervasiveness of this result across multiple domains suggests that general mechanisms might exist underlying females' unique adaptations. An understanding of such processes would enhance knowledge of female health and well-being. (shrink)

High-profile organizations often emphasize fixed giftedness rather than malleable effort-based criteria as critical for excellent achievements. With giftedness being primarily associated with White or Asian males, such organizational implicit theories of excellence may shape individuals’ sense of belonging depending on the extent to which they match the gifted White/Asian male prototype, i.e., the prototypical gifted person which is typically imagined to be a White or Asian male. Previous research has reported fixed excellence theories emphasizing giftedness to impair the sense of (...) belonging of females and negatively stereotyped ethnic minorities. We investigate the combined effects of gender and ethnicity. We predicted that, while individuals whose gender and ethnicity do not match the gifted prototype show a reduced sense of belonging in fixed organizations, White/Asian males who match the gifted prototype show the opposite effect, experiencing a higher sense of belonging in fixed organizations. In an experimental study, we manipulated advertising material used by a highly selective academic institution in Germany and tested effects on students’ belonging. Whereas the original material emphasized giftedness as essential for excelling, our manipulated version stressed effort. As expected, females from stereotyped ethnic minority groups felt less belonging in the fixed organization, while White/Asian males anticipated stronger belonging in the fixed organization. Fixed views of excellence impair negatively stereotyped individuals’ belonging but may even strengthen the belonging of prototypical academic elites. (shrink)

We agree with Archer that human sex differences in aggression are well explained by sexual selection, but note that explanations of human behaviors are not logically mutually exclusive from explanations and therefore should not be framed as such. We discuss why this type of framing hinders the development of both social learning and evolutionary theories of human behavior.

This paper critically analyses three main neurobiological hypotheses on trans* identities: the neurobiological theory about the origin of gender dysphoria, the neurodevelopmental cortical hypothesis, and the alternative hypothesis of self-referential thinking and body perception. In this study I focus then the attention on three elements: the issue of (de)pathologisation, the idea of the trans brain, and the aetiology of trans* identities. While the neurobiological theory about the origin of gender dysphoria and the neurodevelopmental cortical hypothesis claim the existence of the (...) trans brain, each offering its own neurobiological depiction, the hypothesis of self-referential thinking and body perception doesn’t postulate a distinctive neurobiological trait for all trans* people. I problematize both portrayals of the trans brain departing from the findings and conceptualizations of the paradigm shifting brain mosaicism. Unlike the hypothesis of self-referential thinking and body perception that keeps the question of causation open, both the neurobiological theory about the origin of gender dysphoria and the neurodevelopmental cortical hypothesis situate the origin of trans* identities in the neurobiological domain. I challenge the biological deterministic framework in which this aetiology is inscribed from a dynamic processual entanglement perspective. Finally, concerning the issue of (de)pathologisation of trans* identities, an evolution can be seen in each of the hypothesis and among them, from the least to the most depathologising. However, I question their complete departure from a pathologising framework. (shrink)

Extended staying alive theory (SAT) raises the issue of the extent to which its various attributes are linked or whether they provide alternative means to the same adaptive ends. Theories such as SAT that consider an array of sex differences may benefit from the application of the multivariateDstatistic, rather than using a series ofdvalues, as is common at present.

The main goal of the paper was to obtain insights into how gender measures can be incorporated into quantitative research on risk-related behaviour. We explored relations between the measures (short versions of Bem Sex Role Inventory (BSRI), Personal Attributes Questionnaire (PAQ), and Traditional Masculinity-Femininity (TMF) scale) and their explanatory power in relation to risky behaviours (Decision Outcome Inventory, DOI). The sample consisted of 470 adults (238 men). The corresponding BSRI and PAQ subscales correlated significantly, while TMF correlated positively with the (...) femininity subscales. All the instruments demonstrated good internal consistency and the measures explained a significant portion of risky behaviour. The results suggest that, although sex is a proxy of behaviour, using a measure of the gender-related aspects of identity could enhance understanding of risk-related behaviour. Finally, men and women viewed themselves as equally masculine, indicating that gender stereotypes about desirability of agentic characteristics change. (shrink)

Expectation of others’ cooperative behavior plays a core role in economic cooperation. However, the dynamic neural substrates of expectation of cooperation are little understood. To fully understand EOC behavior in more natural social interactions, the present study employed functional near-infrared spectroscopy hyperscanning to simultaneously measure pairs of participants’ brain activations in a modified prisoner’s dilemma game. The data analysis revealed the following results. Firstly, under the high incentive condition, team EOC behavior elicited higher interbrain synchrony in the right inferior frontal (...) gyrus than individual EOC behavior. Meanwhile, the IBS in the IFG could predict the relationship between empathy/agreeableness and EOC behavior, and this prediction role was modulated by social environmental cues. These results indicate the involvement of the human mirror neuron system in the EOC behavior and the different neural substrates between team EOC and individual EOC, which also conform with theory that social behavior was affected by internal and external factors. Secondly, female dyads exhibited a higher IBS value of cooperative expectation than male dyads in the team EOC than the individual EOC in the dorsal medial prefrontal cortex, while in the individual EOC stage, the coherence value of female dyads was significantly higher than that of male dyads under the low incentive reward condition in the rIFG. These sex effects thus provide presumptive evidence that females are more sensitive to environmental cues and also suggest that during economic social interaction, females’ EOC behavior depends on more social cognitive abilities. Overall, these results raise intriguing questions for future research on human cooperative behaviors. (shrink)

Whenever we communicate, we inevitably have to say one thing before another. This means introducing particularly subtle patterns of salience into our language. In this paper, I introduce ‘order-based salience patterns,’ referring to the ordering of syntactic contents where that ordering, pretheoretically, does not appear to be of consequence. For instance, if one is to describe a colourful scarf, it wouldn’t seem to matter if one were to say it is ‘orange and blue’ or ‘blue and orange.’ Despite their apparent (...) triviality, I argue that order-based salience patterns tend to make the content positioned first more salient – in the sense of attention-grabbing – in a way that can have surprising normative implications. Giving relative salience to gender differences over similarities, for instance, can result in the activation of cognitively accessible beliefs about gender differences. Where those beliefs are epistemically and/or ethically flawed, we can critique the salience pattern that led to them, providing an instrumental way of evaluating those patterns. I suggest that order-based salience patterns can also be evaluated on constitutive grounds; talking about gender differences before similarities might constitute a subtle form of bias. Finally, I reflect on how the apparent triviality of order-based salience patterns in language gives them an insidious strength. (shrink)

The purpose of the study was to compare the visuospatial decision-making error scores related to the perception of biological motion of individuals categorized as field dependent or field independent. A sample of 69 participants aged 18-27 years that included 33 males and 36 females completed the experiment. Cognitive style was assessed using the Group Embedded Figure Test. Perception of biological motion was evaluated using two different point-light stimuli developed from video images of a ballet dancer’s performance of a correct and (...) incorrect turn in the fifth position. The results showed that individuals classified as field independent made significantly fewer visuospatial processing errors. The findings are considered and discussed in relation to theoretical perspectives associated with both cognitive processing and cognitive style. (shrink)

Despite tremendous advances in neuroscience, the topic “brain, sex and gender” remains a matter of misleading interpretations, that go well beyond the bounds of science. In the 19th century, the difference in brain sizes was a major argument to explain the hierarchy between men and women, and was supposed to reflect innate differences in mental capacity. Nowadays, our understanding of the human brain has progressed dramatically with the demonstration of cerebral plasticity. The new brain imaging techniques have revealed the role (...) of the environment in continually re-shaping our brain all along our lifetimes as it goes through new experiences and acquires new knowledge. However, the idea that biology is a major determining factor for cognition and behavioral gender differentiation, is still very much alive. The media are far from being the only guilty party. Some scientific circles actively promote the idea of an innate origin of a gender difference in mental capacities. Experimental data from brain imaging, cognitive tests or genetics are often distorted to serve deterministic ideas. Such abuse of “scientific discourses” have to be counteracted by effective communication of clear and unbiased information to the citizens. This paper presents a critical analysis of selected examples which emphasize sex differences in three fields e.g. skills in language and mathematics, testosterone and financial risk-taking behavior, moral cognition. To shed light on the data and the methods used in some papers, we can now—with today’s knowledge on cerebral plasticity—challenge even more strongly, many false interpretations. Our goal here is double: we want to provide evidence against archaic beliefs about the biological determinism of sex differences but also promote a positive image of scientific research. (shrink)

The present study aimed to quantify the magnitude of sex differences in humans' ability to accurately recognise non-verbal emotional displays. Studies of relevance were those that required explicit labelling of discrete emotions presented in the visual and/or auditory modality. A final set of 551 effect sizes from 215 samples was included in a multilevel meta-analysis. The results showed a small overall advantage in favour of females on emotion recognition tasks (d = 0.19). However, the magnitude of that sex difference was (...) moderated by several factors, namely specific emotion, emotion type (negative, positive), sex of the actor, sensory modality (visual, audio, audio-visual) and age of the participants. Method of presentation (computer, slides, print, etc.), type of measurement (response time, accuracy) and year of publication did not significantly contribute to variance in effect sizes. These findings are discussed in the context of social and biological explanations of sex differences in emotion recognition. (shrink)

Moral philosophers argue that mechanisms such as reciprocal altruism and indirect reciprocity can result in the evolution of shared interests and a ‘moral sense’ in humans. This article discusses the need to broaden that view when considering the consequences of genetic conflict, in particular, the conflict associated with mate selection. An alternative application of evolutionary arguments to morality has been suggested by biologists such as Richard Alexander, who argue that ethical, moral and legal questions arise purely out of conflicts of (...) interest, and that moral systems (consisting of societal rules or laws) exist to ameliorate those conflicts. Following Alexander, a novel societal rule is proposed that could lessen the negative consequences to men of reproductive conflicts with women. (shrink)

This paper concerns a project to right a wrong, an epistemic as well as social wrong. The wrong? Science was to serve all humankind; that is what Francis Bacon and the other founders of modern science had promised and what a long line of their successors had signed on to. But by the twentieth century it had become clear that this science was regularly serving some of humankind far more than others and was even, quite frequently, actually harming those others (...) rather than helping them. The problem lay with the knowledge that science offered about those others: the damaging ‘information’ that was really ignorance in disguise. But the problem also lay with the systematic ignorance science allowed, even encouraged, about those others: the helpful, uplifting knowledge about them that the science could have offered but did not. And the project to right the wrong? A transformation of the science-provided pattern of knowledge and ignorance engineered to achieve a more egalitarian result (what I call an epistemological-agnotological reengineering project). Of course, there are many groups of others relevant here. I will focus my attention in the present paper on only two of them: women, and men of colour (especially Black men).. (shrink)

Dynamics of perceiving oneself on femininity and masculinity dimensions in diverse contexts The article is about issues related to gender perceived as a result of social context and thus fits in the current, processual gender paradigm. Two studies have been conducted verifying hypotheses about perceiving oneself on the femininity and masculinity dimensions in various types of contexts. Expectations were that generic contexts would make perceiving oneself within the psychological gender dimensions more dynamic. Women were expected to perceive themselves as more (...) feminine and less masculine in contexts matching their gender, i.e. "feminine", comparing to "masculine", and men were expected to perceive themselves as more masculine and less feminine in "masculine" contexts comparing to "feminine" contexts. Research results do not confirm the above hypotheses and indicate dynamism in perceiving oneself on femininity and masculinity dimensions. However, the dynamism is perceived only on dimensions inconsistent with biological gender - situation affects women's perceiving of themselves on the masculinity dimension and men's - on femininity dimensions.

Previous research has found that sex differences in occupational preferences are both substantial and cross-culturally universal. Androphilic males tend to display “gender-shifted” occupational preferences, with relatively female-typical interests. Past research has overwhelmingly relied on Western samples; this article offers new insights from a non-Western setting. Known locally as fa’afafine, androphilic males in Samoa occupy a third-gender category. Data were collected in Samoa from 103 men, 103 women, and 103 fa’afafine regarding occupational preferences and recalled childhood gender nonconformity (CGN). A substantial (...) sex difference was observed in the occupational preferences of men and women (d = 2.04). Interestingly, women and fa’afafine did not differ in their preferences (p = 0.89), indicating a complete gender inversion of occupational preferences in the latter. Although there was no correlation between women’s CGN and masculine occupational preferences, there was a significant correlation (r = −0.62) between these variables in both men and fa’afafine. Among males (both men and fa’afafine), increased CGN was associated with preference for feminine occupations. The present research corroborates past findings and furnishes support for the conclusion that female-typical occupational preferences are a cross-culturally invariant aspect of male androphilia.

Social scientists agree that women are generally more religious than men, but disagree about whether the differences are universal or contingent on social context. This study uses General Social Survey data to explore differences in religiosity between, as well as among, women and men by level of individual earned income. Extending previous research, I focus on high earners with other groups included for comparison. Predicted probabilities based upon fully interacted models provide four key findings: There are no significant gender differences (...) among high earners; high-earning women are less religious than low-earning women; high-earning men are more religious than low-earning men; and differences among women and among men at different earnings levels are just as large as average differences between women and men. Further analyses demonstrate that the relationship between gender, earnings, and religiosity varies by race. The findings demonstrate the utility of intersectional approaches for understanding gender differences in religiosity. Beyond the implications specific to the gender differences in religiosity literature, this study also indicates that religion is an important, yet often underemphasized, aspect of our intersectional selves.

The so-called expertise defence against sceptical challenges from experimental philosophy has recently come under attack: there are several studies claiming to have found direct evidence that philosophers’ judgments in thought experiments are susceptible to erroneous effects. In this paper, we distinguish between the customary ‘immune experts’ version of the expertise defence and an ‘informed experts’ version. On the informed expertise defence, we argue, philosophers’ judgments in thought experiments could be preferable to those by the folk even if it were true (...) that philosophers’ judgments are no less immune to confounders than judgments by the folk are. We present results from an experimental study comparing philosophers and non-philosophers (n = 484), which support this version of the expertise defence. (shrink)

Proponents of the “negative program” in experimental philosophy have argued that judgements in philosophical cases, also known as case judgements, are unreliable and that the method of cases should be either strongly constrained or even abandoned. Here we put one of the main proponent’s account of why philosophical cases may cause the unreliability of case judgements to the test. We conducted our test with thought experiments from physics, which exhibit the exact same supposedly “disturbing characteristics” of philosophical cases.

Biases in cognition are ubiquitous. Social psychologists suggested biases and stereotypes serve a multifarious set of cognitive goals, while at the same time stressing their potential harmfulness. Recently, biases and stereotypes became the purview of heated debates in the machine learning community too. Researchers and developers are becoming increasingly aware of the fact that some biases, like gender and race biases, are entrenched in the algorithms some AI applications rely upon. Here, taking into account several existing approaches that address the (...) problem of implicit biases and stereotypes, we propose that a strategy to cope with this phenomenon is to unmask those found in AI systems by understanding their cognitive dimension, rather than simply trying to correct algorithms. To this extent, we present a discussion bridging together findings from cognitive science and insights from machine learning that can be integrated in a state-of-the-art semantic network. Remarkably, this resource can be of assistance to scholars (e.g., cognitive and computer scientists) while at the same time contributing to refine AI regulations affecting social life. We show how only through a thorough understanding of the cognitive processes leading to biases, and through an interdisciplinary effort, we can make the best of AI technology. (shrink)

We investigated the accuracy of gender stereotypes regarding digital game genre preferences. In Study 1, 484 female and male participants rated their preference for 17 game genres (gender differences). In Study 2, another sample of 226 participants rated the extent to which the same genres were presumably preferred by women or men (gender stereotypes). We then compared the results of both studies in order to determine the accuracy of the gender stereotypes. Study 1 revealed actual gender differences for most genres—mostly (...) of moderate size. Study 2 revealed substantial gender stereotypes about genre preferences. When comparing the results from both studies, we found that gender stereotypes were accurate in direction for most genres. However, they were, to some degree, inaccurate in size: For most genres, gender stereotypes overestimated the actual gender difference with a moderate mean effect size. (shrink)

Peak alpha frequency is known to vary not just between individuals, but also within an individual over time. While variance in this metric between individuals has been tied to working memory performance, less understood are how short timescale modulations of peak alpha frequency during task performance may facilitate behavior. This gap in understanding may be bridged by consideration of a key difference between individuals: sex. Inconsistent findings in the literature regarding the relationship between peak alpha frequency and cognitive performance, as (...) well as known sex-related-differences in peak alpha frequency and its modulation motivated our hypothesis that cognitive and neural processes underlying working memory—modulation of peak alpha frequency in particular—may differ based upon sex. Targeting sex as a predictive factor, we analyzed the EEG data of participants recorded while they performed four versions of a visual spatial working memory task. A significant difference between groups was present: females modulated peak alpha frequency more than males. Task performance did not differ by sex, yet a relationship between accuracy and peak alpha frequency was present in males, but not in females. These findings highlight the importance of considering sex as a factor in the study of oscillatory activity, particularly to further understanding of the neural mechanisms that underlie working memory.

This paper will unfold in two different critiques, first dealing with how neuroscience has sexed the brain, ignoring cultural elements of gender formation, and further focusing on the masculine bias of neuroscience research, which, we claim, adopts male physiological and social patterns as “normal”. In order to do so, we will start our investigation with some insights on the sex/gender debate and how it is of consequence for research on neurosciences of sexuality. Secondly, we will critic the way studies are (...) focusing on differences rather than similarities between genders, and how such strategy re-enforces gender biases. Finally, we use contributions from social cognitivist theory and feminism to support a more complex view of body, identity and gender performance. (shrink)

Men typically express more willingness than women to perpetrate fraudulent acts like lying in negotiations. However, women express just as much willingness in some cases. We develop and test a theory to explain these mixed findings. Specifically, we hypothesize that situational cues that bring about competitive or empathic feelings mitigate sex differences in lying to negotiation counterparts. Results from four experiments confirm our hypotheses. Experiment 1 showed that men and women express equal willingness to lie when negotiating with counterparts toward (...) whom they felt either great competitiveness or empathy. Experiment 2 extended these results by confirming that men only express more willingness to lie absent competitive or empathic feelings towards a counterpart. Experiments 3 and 4 demonstrated that inducing competitive or empathic feelings toward a counterpart eliminated sex differences in lying by leading women to lie more and men to lie less, respectively. Overall, our results suggest that the extent to which negotiators experience competitive or empathic feelings play important roles in whether sex differences in lying in negotiations emerge.

Del Giudice's model belongs among those that highlight the role of adaptive developmental plasticity in human reproductive strategies; but at least three other forms of evolutionary adaptation also influence reproductive behavior. Similar to earlier models, the existing evidence suggests that Del Giudice's hypothesized effects are rather weak. In particular, adult attachment styles are hardly predictive of outcomes visible to natural selection.

Archer recognizes that sexual selection theory is sensitive to the effects of ecologies on sex differences, yet he does not explain the impact of such variation. For example, to what degree are there sex differences in aggression in polygynous and monogamous societies? I demonstrate how differences in mating perceptions affect the traditional dichotomy that males compete for and females choose mates.

Science motivational beliefs are crucial for STEM (science, technology, engineering, and math) performance and persistence, but these beliefs typically decline during high school. We expanded the literature on adolescents’ science motivational beliefs by examining: 1) changes in motivational beliefs in three specific science subjects, 2) how gender, immigrant generation status, and perceived support from key social agents predicted differences in adolescents’ science motivational beliefs, and 3) these processes among Latino/as in the United States, whose underrepresentation in STEM is understudied. We (...) used hierarchical linear modeling to estimate the changes in 104 (40% female) Latino/a high school students’ physics, chemistry, and biology motivational beliefs from 9th to 11th grade. Subject-specific ability self-concept, interest, and utility were regressed on gender, immigrant generation status, and perceived science support while controlling for family income, parent education, and adolescents’ school. Adolescents’ utility declined from 9th to 11th grade whereas their interest remained stable for all three science subjects. Adolescents’ ability self-concept increased for biology, decreased for physics, but remained stable for chemistry. Gender differences in adolescents’ motivational beliefs at 9th grade only emerged for physics utility as well as physics and chemistry interest; yet, there were no gender differences in how adolescents’ science motivational beliefs changed over time. Contrary to expectations, immigrant generation status was not significantly associated with adolescents’ science motivational beliefs at 9th grade or in terms of how they changed over time. Adolescents who perceived higher science support generally had higher motivational beliefs in 9th grade, but did not differ on their rate of change. Our findings highlight the need to examine specific science subjects, and that typical gender differences in adolescents’ motivational beliefs discussed in the literature may not generalize to all racial and ethnic groups.

Behavioral research has revealed how normal human cognitive processes can tend to lead us astray. But do these affect economic researchers, ourselves? This article explores the consequences of stereotyping and confirmation bias using a sample of published articles from the economics literature on gender and risk aversion.

The questions of how these cognitive biases arise and (...) why they have such power are discussed, and methodological practices that may help to attenuate these biases are outlined. (shrink)

Economic discourse—or the lack of it—about fear is gendered on at least three fronts. First, while masculine-associated notions of reason and mind have historically been prioritized in mainstream economics, fear—along with other emotions and embodiment—has tended to be culturally associated with femininity. Research on cognitive “gender schema,” then, may at least partly explain the near absence of discussions of fear within economic research. Second, in the extremely rare cases where fear and emotion are alluded to within the contemporary economics literature (...) on risk aversion, there is a tendency to strongly associate them with women. Finally, historians and philosophers of science have suggested that the failure to consider the full range of human emotions and experience may be itself rooted in fear: a fear of the feminine. This aversion to discussing fear—especially fear as experienced by men—contributes to serious problems, especially in regard to financial market instability and ecological threats. (shrink)
