Reward Responsiveness, Learning, and Valuation Implicated in Problematic Pornography Use — a Research Domain Criteria Perspective

Purpose of Review

Problematic pornography use (PPU) describes a pattern of behavior characterized by excessive time spent using or thinking about pornography and continued use despite negative consequences. To help advance the understanding of transdiagnostic underlying psychological and neurobiological mechanisms in PPU, we aim to review existing evidence on these mechanisms focusing on positive valence systems within the transdiagnostic Research Domain Criteria (RDoC) framework.

Recent Findings

Reward anticipation processes seem to be increased in individuals with PPU symptoms when they anticipate sexual stimuli compared with other rewards. Studies further suggest that the initial neural and attentional responses to sexual rewards compared with different control stimuli are also increased in individuals with PPU symptoms, as are conditioned responses in sexual reward learning paradigms. Sexual reward valuation studies point towards an increased neural value differentiation with increasing PPU symptoms.

Summary

The current state of evidence indicates that positive valence systems are altered in persons with PPU. This framework of organizing evidence may aid in elucidating PPU development and maintenance as well as planning future studies.

The experience of the COVID-19 pandemic by persons with ASD: Social aspects

While causing a variety of social restrictions, the COVID-19 pandemic has also precipitated the digitalisation of public services and official procedures, reducing many, until recently necessary, immediate social interactions. This study has been conducted to investigate their perception of the COVID-19 pandemic and its impact on their current and future social interactions. To this end, semi-structured narrative interviews were conducted. Ten adults on the autism spectrum participated in the study. The phenomenological analysis of the narratives focused on categories related to the social functioning of the study participants. The interpretation of the narratives has shown that autistic people can experience a sense of loss due to the lack of direct contact. On the other hand, we also talked to the participants who expressed their satisfaction with the situation of obligatory social distance. The respondents also discussed the subject of changing the form of interaction in some areas of public life to one that is more adjusted to the needs of people with their condition. The study concludes with a suggestion that autistic people might benefit from technological progress in institutions and the availability of the option to prefer online contact for interactions that are not strictly necessary.

Sex and gender terminology: a glossary for gender-inclusive epidemiology

There is increased interest in inclusion, diversity and representativeness in epidemiological and community health research. Despite this progress, misunderstanding and conflation of sex and gender have precluded both the accurate description of sex and gender as sample demographics and their inclusion in scientific enquiry aiming to distinguish health disparities due to biological systems, gendered experiences or their social and environmental interactions. The present glossary aims to define and improve understanding of current sex-related and gender-related terminology as an important step to gender-inclusive epidemiological research. Effectively, a proper understanding of sex, gender and their subtleties as well as acknowledgement and inclusion of diverse gender identities and modalities can make epidemiology not only more equitable, but also more scientifically accurate and representative. In turn, this can improve public health efforts aimed at promoting the well-being of all communities and reducing health inequities.

Gender Typicality, Pressure to Conform to Gender Norms, and Anti-Fat and Appearance Stereotypes in Girls

This mixed-methods study investigated the relation among gender identity (i.e., self-perceived gender similarity to girls and boys; self-perceived parental and peer pressure to conform to gender norms) and stereotyping about weight (i.e., anti-fat stereotypes), weight change, and appearance in 83 girls ages 6-9 (M_age = 7.60 years, SD = .85; 65% White, 16% Mixed/Other, 11% Black, 8% Latina) in the U.S. Stereotypes about weight change were assessed with open-ended responses (i.e., qualitatively), and the rest of the constructs were assessed with closed-ended responses (i.e., quantitatively). There was a positive association between pressure from parents to conform to gender norms and appearance stereotypes, and between pressure from peers and negative stereotypes about the fat and thin figures. Girls who were more gender typical, or more similar to girls, were more likely to endorse appearance stereotypes. There was no significant relation among stereotypes about weight change and gender identity. Many girls deemed the fat figure as unattractive, physically restrained, unhealthy, and likely to be bullied and believed that the fat figure should change back to look like a thinner figure. Most girls were aware that exercising, eating healthy, and dietary restriction can lead to weight loss and that food consumption and lack of exercise can lead to weight gain. Findings suggest that certain aspects of weight (anti-fat) and appearance stereotypes are closely linked to gender identity in girls, whereas other aspects of weight stereotypes (e.g., stereotypes about weight change) are so pervasive that they are common in most girls, regardless of their gender identity.

Embracing Complexity: Variation in Faculty's Attitudes toward Inclusive Measures of Gender and Sexuality in Social and Health Sciences Research

In the absence of adequate measurement efforts, expansive gender and sexual identities will remain underexplored in quantitative social science and health research. We use primary survey data (N = 309) to identify factors associated with U.S.based social and health science faculty's attitudes toward inclusive gender and sexuality measures in participant-based research. Results suggest that political science faculty rated expansive gender and sexuality measures as less important to their own research, relative to psychology, sociology, and health sciences faculty. In addition, cisgender/heterosexual women and LGBTQ+ identifying faculty rate and apply these measures more positively compared to faculy who identify as cisgender/heterosexual men. Finally, faculty engaging in predominantly quantitative research, or in teaching-focused positions, had lower ratings of the importance of gender expansive measurement. Results suggest that while individual characteristics shape faculty's attitudes toward and use of inclusive gender and sexuality measures, disciplinary and academic contexts also matter.

Measuring Sex and Gender in Aging and Alzheimer's Research: Results of a National Survey

OBJECTIVE

Differences between men and women are common in published research on aging and Alzheimer's disease and Alzheimer's disease and related dementias (AD/ADRD). What do these differences mean? To answer this, rigorous measurement is needed. We investigated current methods for measuring sex/gender in aging and AD/ADRD cohort studies.

METHOD

An online survey was sent to NIA-funded Alzheimer's Disease Research Centers (ADRCs) (n=38) and investigator-initiated cohort studies (n=38) to assess practices around enrollment of men and women and measurement of sex and gender.

RESULTS

The response rate was 65.8% (n=50). All enrolled men and all but two investigator-initiated studies enrolled women. Most cohorts (43/50) had no documented definitions for categories of "men" or "women". Over 85% of cohorts relied solely on self-report questions to capture sex/gender data (n=43/50). Issues with administration were also identified (n=7).

DISCUSSION

Our findings identify gaps in current approaches used to measure sex and gender in aging and AD/ADRD research. We discuss opportunities to bridge these gaps and advance measurement of sex and gender in aging and AD/ADRD research. Changes are needed to ensure inclusion and representation of sociocultural diversity in research samples, and consistency in data collection in aging and AD/ADRD research.

Normal or tingly? A story about hands and feet

AIMS

Spontaneous sensations (SPS) are sensations that are felt in the body in the absence of external stimulation. The literature on SPS has used explicit measures, such as questionnaires to explore SPS, while no studies to date have examined SPS on an implicit level. This study was conducted to collect representative stimuli that can be used to build such a task, for example, an Implicit Association Test.

METHODS

An online survey was completed by 18 participants to identify the most frequent words used to describe our limbs in the presence or absence of SPS.

RESULTS

Individuals who perceive and those who do not perceive SPS in their limbs describe their limbs as normal, while the most frequently described SPS were itching and tingling.

CONCLUSIONS

Thus, we use the same words/adjectives to describe how we perceive our limbs. However, the way we experience SPS varies as we experience more SPS in hands than feet.

Perceiving gender while perceiving language: Integrating psycholinguistics and gender theory

There is a substantial body of literature showing that men and women speak differently and that these differences are endemic to the speech signal. However, the psycholinguistic mechanisms underlying the integration of social category perception and language are still poorly understood. Speaker attributes such as emotional state, age, sex, and race have often been treated in the literature as dissociable, but perceptual systems for social categories demonstrably rely on interdependent cognitive processes. We introduce a diversity science framework for evaluating the existing literature on gender and speech perception, arguing that differences in beliefs about gender may be defined as differences in beliefs about differences. Treating individual, group, and societal level contrasts in ideological patterns as phenomenologically distinctive, we enumerate six ideological arenas which define claims about gender and examine the literature for treatment of these issues. We argue that both participants and investigators predictably show evidence of differences in ideological attitudes toward the normative definition of persons. The influence of social knowledge on linguistic perception therefore occurs in the context of predictable variation in both attention and inattention to people and the distinguishing features which mark them salient as kinds. We link experiences of visibility, invisibility, and hypervisibility with ideological variation regarding the significance of physiological, linguistic, and social features, concluding that gender ideologies are implicated both in linguistic processing and in social judgments of value between groups. We conclude with a summary of the key gaps in the current literature and recommendations for best practices studies that may use in future investigations of socially meaningful variation in speech perception.

[Assessment and operationalization of the characteristic "gender" in representative population-based surveys: challenges and implications with the example of the GeSiD study]

Repräsentative quantitative Surveys erheben das Geschlecht der Teilnehmenden, um geschlechtsspezifische Analysen im Hinblick auf die jeweiligen Fragestellungen zuzulassen und Rückschlüsse auf die Populationen zu ziehen. Dies ist wichtig, um zielgruppenspezifische Informationen und Angebote zu entwickeln. Doch obwohl Geschlecht nicht mehr ausschließlich als ein binäres Konstrukt betrachtet wird, wird es noch oft durch eine binäre Variable mit den Antwortmöglichkeiten Frau/Mann oder weiblich/männlich erhoben. In diesem Artikel erörtern wir, warum dieses Vorgehen veraltet bzw. unvollständig und eine Abkehr von diesem Ansatz wichtig und notwendig ist. Anhand der GeSiD-Studie zu „Gesundheit und Sexualität in Deutschland“ zeigen wir in diesem Diskussionsbeitrag exemplarisch auf, wie Geschlecht anhand eines zweistufigen Modells erhoben werden kann, bei dem im ersten Schritt das bei der Geburt zugewiesene Geschlecht und im zweiten Schritt die subjektive Geschlechtszugehörigkeit abgefragt wird. Gleichzeitig erörtern wir die Herausforderungen, die dieser Ansatz mit sich bringt. Die Erfahrungen aus der GeSiD-Studie setzen wir in einen größeren Kontext und diskutieren die Implikationen und Möglichkeiten zur Operationalisierung von Geschlecht in repräsentativen Befragungen.

Multidimensional and Intersectional Gender Identity and Sexual Attraction Patterns of Adolescents for Quantitative Research

To identify and compare gender identity and sexual attraction (GISA) patterns using a latent class analysis (LCA), questionnaire data from a cross-sectional study on social resilience in adolescence was conducted in 2020, using a sample of 785 Swiss seventh grade high school students. Following McCall’s complex intersectionality approach, we applied an intracategorical and intersectional approach to reshape, differentiate, and critique the existing binary, heteronormative GISA categorization. To empirically validate the detected classes according to content, we measured the participants’ psychological characteristics with measures of self-esteem, social competence, symptoms of anxiety and depression, dissociation, social desirability, and emotional styles, and related these measures to the respective GISA patterns the LCA detected. The results of our multistep LCA endorsed that heteronormatively binary gender identities are far too simplistic to fully illustrate adolescents’ differences and similarities where gender is concerned. Out of the subsample of n = 785 adolescents (375 identified as “assigned females” and 410 “assigned males”), three significant subgroups of multidimensional GISA patterns emerged for both assigned females and males where differences within the identified GISA groups were larger than those between traditional “boys” and “girls” overall. The LCA demonstrated that the six classes with GISA indicators could be described as low GISA diverse (cis/heterosexual), intermediate GISA diverse (gender identity diverse and/or sexual diverse), high GISA diverse (gender diverse/sexual diverse) for both assigned males and females thus showing that GISA and the psychological state according to gender variance is greater within groups of assigned females and assigned males than between these groups.

Preprinting is positively associated with early career researcher status in ecology and evolution

The usage of preprint servers in ecology and evolution is increasing, allowing research to be rapidly disseminated and available through open access at no cost. Early Career Researchers (ECRs) often have limited experience with the peer review process, which can be challenging when trying to build publication records and demonstrate research ability for funding opportunities, scholarships, grants, or faculty positions. ECRs face different challenges relative to researchers with permanent positions and established research programs. These challenges might also vary according to institution size and country, which are factors associated with the availability of funding for open access journals. We predicted that the career stage and institution size impact the relative usage of preprint servers among researchers in ecology and evolution. Using data collected from 500 articles (100 from each of two open access journals, two closed access journals, and a preprint server), we showed that ECRs generated more preprints relative to non-ECRs, for both first and last authors. We speculate that this pattern is reflective of the advantages of quick and open access research that is disproportionately beneficial to ECRs. There is also a marginal association between first author, institution size, and preprint usage, whereby the number of preprints tends to increase with institution size for ECRs. The United States and United Kingdom contributed the greatest number of preprints by ECRs, whereas non-Western countries contributed relatively fewer preprints. This empirical evidence that preprint usage varies with the career stage, institution size, and country helps to identify barriers surrounding large-scale adoption of preprinting in ecology and evolution.

The Moderating Role of Social Network Size on Social Media Use and Self-Esteem: An Evolutionary Mismatch Perspective

Existing meta-analyses have shown that the relationship between social media use and self-esteem is negative, but at very small effect sizes, suggesting the presence of moderators that change the relationship between social media use and self-esteem. Employing principles from social comparison and evolutionary mismatch theories, we propose that the social network sizes one has on social media play a key role in the relationship between social media use and self-esteem. In our study (N = 123), we showed that social media use was negatively related to self-esteem, but only when their social network size was within an evolutionarily familiar level. Social media use was not related to self-esteem when people's social networks were at evolutionarily novel sizes. The data supported both social comparison and evolutionary mismatch theories and elucidated the small effect size found for the relationship between social media use and self-esteem in current literature. More critically, the findings of this study highlight the need to consider evolutionarily novel stimuli that are present on social media to better understand the behaviors of people in this social environment.

Evoking gender distinctiveness threat in cisgender women lowers their support for gender-inclusive bathroom policies

Some cisgender women oppose policies granting transgender women access to women-only bathrooms. We examined whether this opposition stems from perceiving that transgender women threaten the distinctiveness of the social category “women” (gender distinctiveness threat). Cisgender women ( N = 520) read about a state bill enabling transgender women to use women’s bathrooms. Participants further read that enacting the bill would mean their state officially believes that “transgender women are real women” or “transgender rights are human rights”; in the control condition, this information was omitted. Participants reported their support for the bill and level of gender distinctiveness threat. Cisgender women who read that the bill would imply their state believes transgender women are real women (vs. transgender rights are human rights) reported lower bill support, and this effect was mediated by distinctiveness threat. Perceived threat to the distinctiveness of womanhood may help explain cisgender women’s reluctance to include transgender women in women-only spaces.

How Chatty Are Daddies? An Exploratory Study of Infants' Language Environments

Purpose Fathers play a critical but underresearched role in their children's cognitive and linguistic development. Focusing on two-parent families with a mother and a father, the present longitudinal study explores the amount of paternal input infants hear during the first 2 years of life, how this input changes over time, and how it relates to child volubility. We devote special attention to parentese, a near-universal style of infant-directed speech, distinguished by its higher pitch, slower tempo, and exaggerated intonation. Method We examined the daylong recordings of the same 23 infants at ages 6, 10, 14, 18, and 24 months, given English-speaking families. The infants were recorded in the presence of their parents (mother-father dyads), who were predominantly White and ranged from mid to high socioeconomic status (SES). We analyzed the effects of parent gender and child age on adult word counts and parentese, as well as the effects of maternal and paternal word counts and parentese on child vocalizations. Results On average, the infants were exposed to 46.8% fewer words and 51.9% less parentese from fathers than from mothers, even though paternal parentese grew at a 2.8-times faster rate as the infants aged. An asymmetry emerged where maternal word counts and paternal parentese predicted child vocalizations, but paternal word counts and maternal parentese did not. Conclusions While infants may hear less input from their fathers than their mothers in predominantly White, mid-to-high SES, English-speaking households, paternal parentese still plays a unique role in their linguistic development. Future research on sources of variability in child language outcomes should thus control for parental differences since parents' language can differ substantially and differentially predict child language.

Life With Corona: Increased Gender Differences in Aggression and Depression Symptoms Due to the COVID-19 Pandemic Burden in Germany

Gender differences (GD) in mental health have come under renewed scrutiny during the COVID-19 pandemic. While rapidly emerging evidence indicates a deterioration of mental health in general, it remains unknown whether the pandemic will have an impact on GD in mental health. To this end, we investigate the association of the pandemic and its countermeasures affecting everyday life, labor, and households with changes in GD in aggression, anxiety, depression, and the somatic symptom burden. We analyze cross-sectional data from 10,979 individuals who live in Germany and who responded to the online survey "Life with Corona" between October 1, 2020 and February 28, 2021. We estimate interaction effects from generalized linear models. The analyses reveal no pre-existing GD in aggression but exposure to COVID-19 and COVID-19 countermeasures is associated with sharper increases in aggression in men than in women. GD in anxiety decreased among participants with children in the household (with men becoming more anxious). We also observe pre-existing and increasing GD with regards to the severity of depression, with women presenting a larger increase in symptoms during the hard lockdown or with increasing stringency. In contrast to anxiety, GD in depression increased among participants who lived without children (women > men), but decreased for individuals who lived with children; here, men converged to the levels of depression presented by women. Finally, GD in somatic symptoms decreased during the hard lockdown (but not with higher stringency), with men showing a sharper increase in symptoms, especially when they lived with children or alone. Taken together, the findings indicate an increase in GD in mental health as the pandemic unfolded in Germany, with rising female vulnerability to depression and increasing male aggression. The combination of these two trends further suggests a worrying mental health situation for singles and families. Our results have important policy implications for the German health system and public health policy. This public health challenge requires addressing the rising burden of pandemic-related mental health challenges and the distribution of this burden between women and men, within families and for individuals who live alone.

Testing for Sex Differences in the Nomological Network of the Triarchic Model of Psychopathy in Incarcerated Individuals

The triarchic model of psychopathy conceptualizes variants of this clinical condition as expressions of three distinct biobehavioral dispositions, termed boldness, meanness, and disinhibition. As a trait-oriented model, the triarchic model situates psychopathy within a broader nomological network of personality and psychopathology, and has proven useful for characterizing how psychopathy relates to variables in these domains as well as to biological and behavioral variables. The current study was the first to examine sex differences in the external correlates of psychopathic traits as described by the triarchic model in a prison sample. Results were generally consistent with hypotheses: The triarchic traits related to measures of personality and psychopathology in patterns that were largely consistent across sex, but with some notable differences between males and females, in the correlates of disinhibition in particular. These included stronger associations for disinhibition with substance use problems, self-harm, and staff ratings of prison misbehavior among females compared to males. Findings from this study support the value of the triarchic model for understanding similarities and differences in the nomological network of psychopathy in incarcerated males and females.

The Friends-to-Lovers Pathway to Romance: Prevalent, Preferred, and Overlooked by Science

There is more than one pathway to romance, but relationship science does not reflect this reality. Our research reveals that relationship initiation studies published in popular journals (Study 1) and cited in popular textbooks (Study 2) overwhelmingly focus on romance that sparks between strangers and largely overlook romance that develops between friends. This limited focus might be justified if friends-first initiation was rare or undesirable, but our research reveals the opposite. In a meta-analysis of seven samples of university students and crowdsourced adults (Study 3; N = 1,897), two thirds reported friends-first initiation, and friends-first initiation was the preferred method of initiation among university students (Study 4). These studies affirm that friends-first initiation is a prevalent and preferred method of romantic relationship initiation that has been overlooked by relationship science. We discuss possible reasons for this oversight and consider the implications for dominant theories of relationship initiation.

Associations between COVID-19 perceptions, anxiety, and depressive symptoms among adults living in the United States

BACKGROUND

Associations among illness perceptions of viruses, anxiety and depression symptoms, and self-management decisions, such as mask-wearing, are critical to informing public health practices to mitigate the short- and long-term consequences of the SARS-CoV-2 viral pandemic.

PURPOSE

Guided by the common-sense model of self-regulation, this observational study examined associations among illness perceptions of COVID-19, anxiety, and depression symptoms among community-dwelling adults.

METHOD

Data were collected from 1380 adults living in the United States early in the pandemic (03-23-2020 to 06-02-2020). Participants completed online surveys. Analyses were conducted using descriptive statistics and correlations.

FINDINGS

While increased anxiety symptoms were associated with less perceived personal control, greater concern, and higher emotional responsiveness, increased depression symptoms were related to lower concern as well as greater emotional responsiveness and perceived consequences of the pandemic.

DISCUSSION

Associations among illness perceptions, anxiety, and depression symptoms may impact viral spread mitigation behavior adoption.

Instructional Communities of Practice during COVID-19: Social Networks and Their Implications for Resilience

In response to the COVID-19 pandemic, most spring 2020 university courses were abruptly transitioned mid-semester to remote learning. The current study was an exploratory investigation into the interactions among individuals within a single biology department during this transition. Our goal was to describe the patterns of interactions among members of this community, including with whom they gave advice on instruction, shared materials, co-constructed materials, and shared emotions, during the rapid online transition. We explored how instructional teams (i.e., the instructor of record and graduate teaching assistants, or GTAs, assigned to a single course) organized themselves, and what interactions exist outside of these instructional teams. Using social network analysis, we found that the flow of resources and support among instructional staff within this department suggest a collaborative and resilient community of practice. Most interactions took place between instructional staff teaching in the same course. While faculty members tended to have more connections than GTAs, GTAs remained highly interactive in this community. We consider how the observed networks might reflect a mobilization of social resources that are important for individual and departmental resilience in a time of crisis. Actively promoting supportive networks and network structures may be important as higher education continues to cope and adapt to the changing landscape brought on by COVID-19.

Gender, face mask perceptions, and face mask wearing: Are men being dangerous during the COVID-19 pandemic?

Recent popular press authors have proposed that men are less likely to wear face masks during the COVID-19 pandemic. We investigate this notion in the current article by analyzing three extant datasets. We also assess the mediating effect of eight different face mask perceptions in the relation between gender and face mask wearing via the Face Mask Perceptions Scale. Across the three datasets, the sample-size weighted meta-analytic correlation between gender and face mask wearing was not statistically significant, and no face mask perception was a consistent mediator of this effect. Gender did have significant relations with two face mask perceptions, however. Men were more likely to perceive face masks as infringing on their independence, whereas women were more likely to perceive face masks as uncomfortable. Therefore, although gender does not relate to whether a person wears a face mask, it does relate to face mask perceptions. We offer several suggestions for research and practice from these results, such as the positioning of face mask wearing alongside passive health behaviors, the broader study of face mask perceptions' outcomes beyond face mask wearing, as well as the creation of interventions to target differing face mask perceptions across genders.
