Eating pigs, not Peppa Pig: The effect of identifiability on children's propensity to humanize, befriend, and consume edible animals.

This research aimed to provide experimental evidence on whether identifying an edible animal by a name and specific preferences encourages children to perceive the animal as more similar to humans, increases their willingness to befriend the animal, and makes them less willing to consume it. In two pre-registered studies involving 208 preschool children, participants were presented with pictures of pigs (Study 1) and chickens (Study 2). In the identifiability condition, one animal was depicted with individual qualities such as a name and personal preferences, while in the non-identifiability condition, animals were portrayed with characteristics representative of the entire species. The children then rated their desire to befriend and consume the animal, while in Study 2, they also rated the animal's similarity to humans. The results revealed that animal identifiability led to higher perceived similarity to humans, increased the desire to befriend it, and reduced inclination to consume the animal. These findings highlight animal identifiability's powerful and robust effect on children's attitudes toward edible animals.

Other- (vs. self-) oriented meaning interventions enhance momentary work engagement through changes in work meaningfulness.

We tested whether a short, online meaning intervention boosts momentary work engagement (MWE) through an increase in perceived work meaningfulness. In Study 1 (N = 227), employees who were asked to write why their work was meaningful subsequently experienced higher work meaningfulness and higher MWE compared to a control group. Work meaningfulness mediated the relationship between the intervention and MWE. Study 2, conducted among employees (N = 254), found that writing about how one's work serves a greater good (vs. how it advances personal career, vs. control) led to an increase in work meaningfulness, which consequently predicted MWE. The research examines a new tool to enhance work meaningfulness that can be easily and widely applied and that provides insight into how sources of meaningful work are related to work meaningfulness and to important occupational outcomes.

Sex differences in human mate preferences vary across sex ratios.

A wide range of literature connects sex ratio and mating behaviours in non-human animals. However, research examining sex ratio and human mating is limited in scope. Prior work has examined the relationship between sex ratio and desire for short-term, uncommitted mating as well as outcomes such as marriage and divorce rates. Less empirical attention has been directed towards the relationship between sex ratio and mate preferences, despite the importance of mate preferences in the human mating literature. To address this gap, we examined sex ratio's relationship to the variation in preferences for attractiveness, resources, kindness, intelligence and health in a long-term mate across 45 countries (n = 14 487). We predicted that mate preferences would vary according to relative power of choice on the mating market, with increased power derived from having relatively few competitors and numerous potential mates. We found that each sex tended to report more demanding preferences for attractiveness and resources where the opposite sex was abundant, compared to where the opposite sex was scarce. This pattern dovetails with those found for mating strategies in humans and mate preferences across species, highlighting the importance of sex ratio for understanding variation in human mate preferences.

Friends are not to be eaten: Children are reluctant to eat cookies that share physical and psychological human features due to their desire to relate to the food.

Children's food marketers very often use anthropomorphism in advertising as if it is an effective technique aimed at increasing food consumption. However, the evidence supporting this effect is mixed. In this research, we propose that while a food product's humanlike appearance (physical anthropomorphism) may increase consumption, attribution of mental states and emotions (psychological anthropomorphism) to a physically anthropomorphized food product discourages consumption because it facilitates the formation of a social-like relationship with the food. In two studies, we tested this prediction on samples of children. Preschoolers (N = 91 and N = 97) were randomly assigned to one of three conditions in which they were presented with a cookie that was both physically and psychologically anthropomorphized, physically anthropomorphized only, or not anthropomorphized. In two studies, we observed whether children left alone with the cookie would consume it and how quickly it would happen. Additionally, in Study 2, we asked children about their desire to relate to the cookie. The results confirmed that physical anthropomorphism accompanied by psychological anthropomorphism considerably reduced consumption of the cookies compared to both mere physical anthropomorphism and non-anthropomorphism. Moreover, the reduced appetite for cookies that were physically and psychologically anthropomorphized was mediated by the desire to relate to them. We discuss the implications of these results.

Sex Differences in Mate Preferences Across 45 Countries: A Large-Scale Replication.

Considerable research has examined human mate preferences across cultures, finding universal sex differences in preferences for attractiveness and resources as well as sources of systematic cultural variation. Two competing perspectives-an evolutionary psychological perspective and a biosocial role perspective-offer alternative explanations for these findings. However, the original data on which each perspective relies are decades old, and the literature is fraught with conflicting methods, analyses, results, and conclusions. Using a new 45-country sample (N = 14,399), we attempted to replicate classic studies and test both the evolutionary and biosocial role perspectives. Support for universal sex differences in preferences remains robust: Men, more than women, prefer attractive, young mates, and women, more than men, prefer older mates with financial prospects. Cross-culturally, both sexes have mates closer to their own ages as gender equality increases. Beyond age of partner, neither pathogen prevalence nor gender equality robustly predicted sex differences or preferences across countries.

Global Study of Social Odor Awareness.

Olfaction plays an important role in human social communication, including multiple domains in which people often rely on their sense of smell in the social context. The importance of the sense of smell and its role can however vary inter-individually and culturally. Despite the growing body of literature on differences in olfactory performance or hedonic preferences across the globe, the aspects of a given culture as well as culturally universal individual differences affecting odor awareness in human social life remain unknown. Here, we conducted a large-scale analysis of data collected from 10 794 participants from 52 study sites from 44 countries all over the world. The aim of our research was to explore the potential individual and country-level correlates of odor awareness in the social context. The results show that the individual characteristics were more strongly related than country-level factors to self-reported odor awareness in different social contexts. A model including individual-level predictors (gender, age, material situation, education, and preferred social distance) provided a relatively good fit to the data, but adding country-level predictors (Human Development Index, population density, and average temperature) did not improve model parameters. Although there were some cross-cultural differences in social odor awareness, the main differentiating role was played by the individual differences. This suggests that people living in different cultures and different climate conditions may still share some similar patterns of odor awareness if they share other individual-level characteristics.

Too humanlike to increase my appetite: Disposition to anthropomorphize animals relates to decreased meat consumption through empathic concern.

People who exclude meat from their diets are not only devoid of situational pressures to disengage morally and deny humanlike mental states to animals but also they may be dispositionally more inclined to ascribe human-like qualities to non-human animals than omnivores. The aim of this research was to test whether individual differences in anthropomorphism are related to empathic connection with non-human animals and hence decreased meat consumption. In two studies (N = 588) we confirmed that decreased meat consumption was associated with both increased recognition of human features of animals and increased empathy to animals. Most importantly, our data support a model in which animals' anthropomorphism predicts empathy. Empathy, in turn, increases the importance that potential animal harm plays in dietary choices regarding meat, leading to reduced meat consumption.

I Like the Food You Made! Overly Positive Feedback Is Most Likely Given to Those That Want to Excel in a Task and Handle Failure Badly.

In this article, we focus on how people resolve the dilemma between honest feedback and a prosocial lie depending on the context. In a pre-registered study (N = 455), we asked participants to choose between telling the blatant truth or lying prosocially regarding a dish made poorly by a stranger. The results showed that participants were most eager to pass on overly positive feedback when the stranger cared about cooking and was very sensitive to negative feedback. Perceived harm in truth telling mediated the relationship between desire to excel in a task with high ability to handle failure and choosing a prosocial lie.

The efficient measurement of individual differences in meaning motivation: The need for sense-making short form.

People differ in the extent to which they express a need for sense-making (NSM), and these individual differences are important to understand in light of meaning-making processes. To quantify this important variable, we originally proposed a need for sense-making scale. We now propose a refined, similarly reliable short version of the scale (NSM-SF). The 7-item NSM-SF was validated across a series of four studies (combined N = 1,243). NSM-SF showed psychometric properties and correlations consistent with its longer forerunner. Additionally, results indicated that the need for sense-making was moderately positively related to the satisfaction of basic psychological needs (autonomy, relatedness and competence), and it related negatively to the frustration of these needs. The research offers a useful, brief tool for assessing the NSM construct and broadens our understanding of basic psychological motivations.

Universality of the Triangular Theory of Love: Adaptation and Psychometric Properties of the Triangular Love Scale in 25 Countries.

The Triangular Theory of Love (measured with Sternberg's Triangular Love Scale - STLS) is a prominent theoretical concept in empirical research on love. To expand the culturally homogeneous body of previous psychometric research regarding the STLS, we conducted a large-scale cross-cultural study with the use of this scale. In total, we examined more than 11,000 respondents, but as a result of applied exclusion criteria, the final analyses were based on a sample of 7332 participants from 25 countries (from all inhabited continents). We tested configural invariance, metric invariance, and scalar invariance, all of which confirmed the cultural universality of the theoretical construct of love analyzed in our study. We also observed that levels of love components differ depending on relationship duration, following the dynamics suggested in the Triangular Theory of Love. Supplementary files with all our data, including results on love intensity across different countries along with STLS versions adapted in a few dozen languages, will further enable more extensive research on the Triangular Theory of Love.

Affective Interpersonal Touch in Close Relationships: A Cross-Cultural Perspective.

Interpersonal touch behavior differs across cultures, yet no study to date has systematically tested for cultural variation in affective touch, nor examined the factors that might account for this variability. Here, over 14,000 individuals from 45 countries were asked whether they embraced, stroked, kissed, or hugged their partner, friends, and youngest child during the week preceding the study. We then examined a range of hypothesized individual-level factors (sex, age, parasitic history, conservatism, religiosity, and preferred interpersonal distance) and cultural-level factors (regional temperature, parasite stress, regional conservatism, collectivism, and religiosity) in predicting these affective-touching behaviors. Our results indicate that affective touch was most prevalent in relationships with partners and children, and its diversity was relatively higher in warmer, less conservative, and religious countries, and among younger, female, and liberal people. This research allows for a broad and integrated view of the bases of cross-cultural variability in affective touch.

Polish Adaptation of the Basic Psychological Need Satisfaction and Frustration Scale.

This article presents the findings of four studies designed to validate the translated Polish version of the Basic Psychological Need Satisfaction and Frustration Scale. Results of exploratory factor analyses in Study 1 (N = 272, M age = 41.07) showed that the psychological need for autonomy, relatedness, and competence that are central to the Self-Determination Theory have a bidimensional structure, involving both a need for satisfaction and need for frustration component. Subsequent confirmatory factor analyses in Study 2 (N = 265; M age = 38.15) provided further evidence for a six-dimensional structure of the scale, thereby distinguishing a satisfaction and frustration component for each of the three needs. Study 3 (N = 158; M age = 27.28) further revealed that the distinguished subscales are moderately to highly internally consistent and yielded good test-retest reliability. Finally, Study 4 (N = 204; M age = 20.57) confirmed that satisfaction of the needs is positively related to well-being, while frustration is positively related to depressive symptoms. The Polish version of the Basic Psychological Need Satisfaction and Frustration Scale can be successfully used in future basic and applied studies in the context of Self-Determination Theory.

Cultural Collectivism and Tightness Moderate Responses to Norm Violators: Effects on Power Perception, Moral Emotions, and Leader Support.

Responses to norm violators are poorly understood. On one hand, norm violators are perceived as powerful, which may help them to get ahead. On the other hand, norm violators evoke moral outrage, which may frustrate their upward social mobility. We addressed this paradox by considering the role of culture. Collectivistic cultures value group harmony and tight cultures value social order. We therefore hypothesized that collectivism and tightness moderate reactions to norm violators. We presented 2,369 participants in 19 countries with a norm violation or a norm adherence scenario. In individualistic cultures, norm violators were considered more powerful than norm abiders and evoked less moral outrage, whereas in collectivistic cultures, norm violators were considered less powerful and evoked more moral outrage. Moreover, respondents in tighter cultures expressed a stronger preference for norm followers as leaders. Cultural values thus influence responses to norm violators, which may have downstream consequences for violators' hierarchical positions.

Contrasting Computational Models of Mate Preference Integration Across 45 Countries.

Humans express a wide array of ideal mate preferences. Around the world, people desire romantic partners who are intelligent, healthy, kind, physically attractive, wealthy, and more. In order for these ideal preferences to guide the choice of actual romantic partners, human mating psychology must possess a means to integrate information across these many preference dimensions into summaries of the overall mate value of their potential mates. Here we explore the computational design of this mate preference integration process using a large sample of n = 14,487 people from 45 countries around the world. We combine this large cross-cultural sample with agent-based models to compare eight hypothesized models of human mating markets. Across cultures, people higher in mate value appear to experience greater power of choice on the mating market in that they set higher ideal standards, better fulfill their preferences in choice, and pair with higher mate value partners. Furthermore, we find that this cross-culturally universal pattern of mate choice is most consistent with a Euclidean model of mate preference integration.

When is a lie acceptable? Work and private life lying acceptance depends on its beneficiary.

In this article we show that when analyzing attitude towards lying in a cross-cultural setting, both the beneficiary of the lie (self vs other) and the context (private life vs. professional domain) should be considered. In a study conducted in Estonia, Ireland, Mexico, The Netherlands, Poland, Spain, and Sweden (N = 1345), in which participants evaluated stories presenting various types of lies, we found usefulness of relying on the dimensions. Results showed that in the joint sample the most acceptable were other-oriented lies concerning private life, then other-oriented lies in the professional domain, followed by egoistic lies in the professional domain; and the least acceptance was shown for egoistic lies regarding one's private life. We found a negative correlation between acceptance of a behavior and the evaluation of its deceitfulness.

Registered Replication Report: Dijksterhuis and van Knippenberg (1998).

Dijksterhuis and van Knippenberg (1998) reported that participants primed with a category associated with intelligence ("professor") subsequently performed 13% better on a trivia test than participants primed with a category associated with a lack of intelligence ("soccer hooligans"). In two unpublished replications of this study designed to verify the appropriate testing procedures, Dijksterhuis, van Knippenberg, and Holland observed a smaller difference between conditions (2%-3%) as well as a gender difference: Men showed the effect (9.3% and 7.6%), but women did not (0.3% and -0.3%). The procedure used in those replications served as the basis for this multilab Registered Replication Report. A total of 40 laboratories collected data for this project, and 23 of these laboratories met all inclusion criteria. Here we report the meta-analytic results for those 23 direct replications (total N = 4,493), which tested whether performance on a 30-item general-knowledge trivia task differed between these two priming conditions (results of supplementary analyses of the data from all 40 labs, N = 6,454, are also reported). We observed no overall difference in trivia performance between participants primed with the "professor" category and those primed with the "hooligan" category (0.14%) and no moderation by gender.

White Lies in Hand: Are Other-Oriented Lies Modified by Hand Gestures? Possibly Not.

Previous studies have shown that the hand-over-heart gesture is related to being more honest as opposed to using self-centered dishonesty. We assumed that the hand-over-heart gesture would also relate to other-oriented dishonesty, though the latter differs highly from self-centered lying. In Study 1 (N = 79), we showed that performing a hand-over-heart gesture diminished the tendency to use other-oriented white lies and that the fingers crossed behind one's back gesture was not related to higher dishonesty. We then pre-registered and conducted Study 2 (N = 88), which was designed following higher methodological standards than Study 1. Contrary, to the findings of Study 1, we found that using the hand-over-heart gesture did not result in refraining from using other-oriented white lies. We discuss the findings of this failed replication indicating the importance of strict methodological guidelines in conducting research and also reflect on relatively small effect sizes related to some findings in embodied cognition.
