Sociosexual orientation, life history strategy, and reproductive success
An Experimental Test of Stereotype Congruency in Credibility Assessments of Sexual Orientation Asylum Claims
Previous research has highlighted a concerning reliance on stereotypes in assessing credibility of asylum claims based on sexual orientation. To experimentally examine the mechanisms behind this, 383 participants evaluated a realistic asylum casefile paired with a picture of an asylum seeker digitally altered to present either stereotype‐congruent (feminine gay men, masculine lesbians) or stereotype‐incongruent (masculine gay men, feminine lesbia…
Do Age and Sex Moderate the Mediating Role of Perceived Stress in the Association Between Loneliness and Depression? A Population-Based Study With Finnish Adults
Loneliness is a global issue with numerous negative health outcomes, depression being among the most well-documented. However, the mechanisms underlying this connection remain poorly understood. Recent research and theory suggest perceived stress may mediate the relationship between loneliness and depression. Using data from a Finnish population-based sample of 9,752 adults (age range: 18–88; women: 66.4%), we examined whether perceived stress me…
Sex workers' professional agency, quality of life, and problematic substance use in Finland
INTRODUCTION: Sex workers suffer considerable marginalization that limits their choices and exposes them to various types of harm. Hence, it is important to examine sex workers' professional agency and its association with quality of life. In the current study, we investigated professional agency, quality of life, and problematic substance use among sex workers in Finland. METHODS: Using an online survey, we collected data from 136 sex workers co…
Finnish district judges' assessments of live versus video‐mediated party statements in court
The increase in remote hearings after the COVID‐19 pandemic presents an urgent need to examine how judges assess video‐mediated witness and party statements compared with live statements. There is currently a limited body of research on this subject. As for the assessment itself, professionals within the judicial system sometimes believe they can detect deception based on visible cues such as body language and emotional expression. Research has, …
Exploring Attitudes Toward “Sugar Relationships” Across 87 Countries
The current study investigates attitudes toward one form of sex for resources: the so-called sugar relationships, which often involve exchanges of resources for sex and/or companionship. The present study examined associations among attitudes toward sugar relationships and relevant variables (e.g., sex, sociosexuality, gender inequality, parasitic exposure) in 69,924 participants across 87 countries. Two self-report measures of Acceptance of Suga…
Young People’s Reasons for and Emotional Reactions to Sexting in Intimate Relationships
Although sexting is a widespread phenomenon among today's youth, little is known about their experiences of sexting with their intimate partners. This study addresses this gap by examining young people's reasons for sexting and emotional reactions to sending and receiving sexts in their intimate relationships, as reported by 764 (48.7% girls) 15-20-year-olds in Finland. Both younger and older girls and boys reported mostly positive reactions to b…
Does bilingualism come with linguistic costs? A meta-analytic review of the bilingual lexical deficit
A series of recent studies have shown that the once-assumed cognitive advantage of bilingualism finds little support in the evidence available to date. Surprisingly, however, the view that bilingualism incurs linguistic costs (the so-called lexical deficit) has not yet been subjected to the same degree of scrutiny, despite its centrality for our understanding of the human capacity for language. The current study implemented a comprehensive meta-a…
Cross-language generalization of language treatment in multilingual people with post-stroke aphasia
Spillover effects of the Covid-19 pandemic on attitudes to influenza and childhood vaccines
The current study sought to determine whether public perceptions of other vaccines and diseases than COVID-19 have been impacted by the COVID-19 pandemic. We longitudinally examined whether there had been a change from before the COVID-19 pandemic to during the pandemic in: (a) influenza vaccination behaviour and intentions; (b) the perceived benefit of childhood vaccines and influenza vaccines; (c) the perceived safety of childhood vaccines and …
An Agent-Based Model of Sex and Sexual Orientation Differences in Short-Term Mating Behaviors as a Result of Mating Preferences
Sex differences in short-term mating behaviors are well-documented in human sexuality research. Existing studies usually explain sex differences in sexual behaviors through differences in mating preferences, which is theoretically problematic. Using an agent-based model, we investigated the circumstances under which males' and females' differential preferences for short-term mating would result in sex differences in short-term mating behaviors. T…

Acoustic regularities in infant-directed speech and song across cultures
Fearing the disease or the vaccine
As studies indicate that people perceive COVID-19 as a threatening disease, the demand for a vaccine against the disease could be expected to be high. Vaccine safety concerns might nevertheless outweigh the perceived disease risks when an individual decides whether or not to accept the vaccine. We investigated the role of perceived risk of COVID-19 (i.e., perceived likelihood of infection, perceived disease severity, and disease-related worry) an…
Familicide
Familicides have received relatively little attention and are mostly discussed in studies with broader aims. Here, we reviewed 67 studies from 18 countries on familicides, in which an offender killed or attempted to kill their current or former spouse/intimate partner and one or more of their biological or stepchildren. We conducted a systematic literature search in PubMed, PsycINFO, and Google Scholar. Eight studies investigated familicide speci…
Unwillingness to engage in behaviors that protect against Covid-19
Distrusting the establishment to provide accurate information, believing in conspiracy theories, and endorsing treatments and substances that are not part of conventional medicine, are all associated with a more negative response to the official guidelines during COVID-19. How people respond to the guidelines, however, is more strongly and consistently related to the degree of trust they feel in the information sources, than to their tendency to …
A multi-country test of brief reappraisal interventions on emotions during the Covid-19 pandemic
To which world regions does the valence-dominance model of social perception apply
Over the past 10 years, Oosterhof and Todorov’s valence–dominance model has emerged as the most prominent account of how people evaluate faces on social dimensions. In this model, two dimensions (valence and dominance) underpin social judgements of faces. Because this model has primarily been developed and tested in Western regions, it is unclear whether these findings apply to other regions. We addressed this question by replicating Oosterhof an…

Discrimination based on gender and ethnicity in English and Polish housing markets
Discrimination in the housing market is associated with decreased social integration and is costly at both social and individual levels. Here, we studied discrimination in English and Polish housing markets. In line with previous research, we expected ethnic‐ and gender‐based discrimination to occur in both housing markets. Conducting a preregistered field experiment of discrimination in the housing market, we sent e‐mails with inquiries about ad…
Child Maltreatment and Adult Sexual Assault Victimization
Despite the pervasiveness of adult sexual assault (ASA), evidence-based knowledge on the risk factors for sexual victimization is insufficient. Here, we investigated the etiology of ASA in a population-based Finnish twin sample. Specifically, we estimated the extent of the genetic and environmental influences on the risk of ASA, and we examined its phenotypic and genetic associations with five types of child maltreatment (CM). We found large uniq…

The Psychological Science Accelerator
Concerns about the veracity of psychological research have been growing. Many findings in psychological science are based on studies with insufficient statistical power and nonrepresentative samples, or may otherwise be limited to specific, ungeneralizable settings or populations. Crowdsourced research, a type of large-scale collaboration in which one or more research projects are conducted across multiple lab sites, offers a pragmatic solution t…
Is bilingualism associated with enhanced executive functioning in adults? A meta-analytic review
Because of enduring experience of managing two languages, bilinguals have been argued to develop superior executive functioning compared with monolinguals. Despite extensive investigation, there is, however, no consensus regarding the existence of such a bilingual advantage. Here we synthesized comparisons of bilinguals' and monolinguals' performance in six executive domains using 891 effect sizes from 152 studies on adults. We also included unpu…

Adult-Adult and Adult-Child/Adolescent Online Sexual Interactions
Alcohol intoxication, sexual arousal, and negative emotional states have been found to precede certain sexual behaviors. Using data from an online self-report survey distributed to adults (N = 717; 423 men and 304 women), we compared adults with adult online sexual interactions (n = 640; 89.3%) to adults with interactions with a child or an adolescent (n = 77; 10.7%) on how much they reported being affected by the following factors surrounding th…
