Sniffing out emotion
Odors are closely linked to emotions, yet there is limited understanding of how specific odors elicit emotions in children and adolescents. This study aims to analyze the number and types of important odors reported by children and adolescents and to explore sex- and age-related differences in how specific odors are linked to basic emotions. A total of 197 participants (100 boys, 97 girls) aged 11–17 were asked to name odors that elicit specific …
Past, Present, and Future of Human Chemical Communication Research
Although chemical signaling is an essential mode of communication in most vertebrates, it has long been viewed as having negligible effects in humans. However, a growing body of evidence shows that the sense of smell affects human behavior in social contexts ranging from affiliation and parenting to disease avoidance and social threat. This article aims to (a) introduce research on human chemical communication in the historical context of the beh…

The function of love
Attraction in every sense
What makes someone attractive has been examined for faces, in terms of common preferences, and for opposite-sex interactions. We expanded on this by considering also other non-verbal modalities, personal preferences and same-sex interactions. We presented the face, body motion, voice and body odour from 61 non-verbal agents (34 women) as stimuli in an attractiveness rating to 71 perceivers (37 women). Our results showed that the modalities were d…
Support or stress? How attachment and relationship dynamics associate with acute psychosocial stress in the presence of the romantic partner
Determinants for positive and negative experiences of interpersonal touch
The goal of the study was to determine which aspects of interpersonal touch interactions lead to a positive or negative experience. Previous research has focused primarily on physical characteristics. We suggest that this may not be sufficient to fully capture the complexity of the experience. Specifically, we examined how fulfilment of psychological needs influences touch experiences and how this relates to physical touch characteristics and sit…
The Functions of Human Touch
There appears to be no attempt to categorize the specific classes of behavior that the tactile system underpins. Awareness of how an organism uses touch in their environment informs understanding of its versatility in non-verbal communication and tactile perception. This review categorizes the behavioral functions underpinned by the tactile sense, by using three sources of data: (1) Animal data, to assess if an identified function is conserved ac…
Conservatism Negatively Predicts Creativity
Previous studies have found a negative relationship between creativity and conservatism. However, as these studies were mostly conducted on samples of homogeneous nationality, the generalizability of the effect across different cultures is unknown. We addressed this gap by conducting a study in 28 countries. Based on the notion that attitudes can be shaped by both environmental and ecological factors, we hypothesized that parasite stress can also…
Effects of sickness manipulation on disgust and pleasantness in interpersonal touch
The theory of the behavioral immune system (BIS) describes a set of behaviors that protect the individual from infectious diseases and that are motivated by disgust and the perceived vulnerability to disease. As interpersonal touch is one of the most common situations of potential transmission of infectious diseases in our everyday life, it seems likely that being touched by an apparently sick individual activates disgust. Our aim was to determin…
What Makes Touch Comfortable? An Examination of Touch Giving and Receiving in Two Cultures
This study examined how touch role and culture shape affective touch experiences. Germans ( N = 130) and Chinese ( N = 130) were surveyed once as toucher and once as touchee. For different touch actions, they (a) provided free-text descriptions of what prompts touch, (b) indicated with whom touch feels comfortable, and (c) highlighted areas of touch comfort on a body outline. Overall, touch was prompted by affectionate feelings, was more comforta…
Facial disgust in response to touches, smells, and tastes
Disgust serves to defend the body from the entry of toxins and disease. Central to this function is a strong relationship with the proximate senses of smell, taste, and touch. Theory suggests that distinct and reflexive facial movements should be evoked by gustatory and olfactory disgusts, serving to impede bodily entry. While this hypothesis has received some support from facial recognition studies, whether smell and taste disgusts actually prod…
Covid-19 and Social Distancing
The COVID-19 pandemic has led to the introduction of unprecedented safety measures, one of them being physical distancing recommendations. Here, we assessed whether the pandemic has led to long-term effects on two important physical distancing aspects, namely interpersonal distance preferences and interpersonal touch behaviors. We analyzed nearly 14,000 individual cases from two large, cross-cultural surveys – the first conducted 2 years prior to…
Affective Interpersonal Touch in Close Relationships
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…
More than one kind
The study of affectionate touch centers on gentle stroking. Yet friendly physical contact entails other actions, such as embracing, holding, kissing, leaning, petting, squeezing, or tickling. Here, we probed whether these actions are redundant or can be meaningfully differentiated by asking participants ( N = 161) to complete a few tasks for each action. Coloring of body maps emphasized touching of upper body hairy and glabrous skin, contrary to …
Interpersonal distancing preferences, touch behaviors to strangers, and country-level early dynamics of Sars-CoV-2 spread
The recent Coronavirus Disease 2019 (COVID-19) pandemic has led to "social distancing" recommendations from public health organizations, as physical closeness bears the risk of person-to-person Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) transmission. Here, it was explored if interpersonal distance preferences and touch behaviors in 41 countries were valid measures of physical distancing in contacts between strangers and whether …
Sex Differences in Mate Preferences Across 45 Countries
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 li…

Universality of the Triangular Theory of Love
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 ba…

Olfactory Function Relates to Sexual Experience in Adults
Sad man’s nose
Emotional and olfactory processing is frequently shown to be closely linked both anatomically and functionally. Depression, a disease closely related to the emotional state of sadness, has been shown to be associated with a decrease in olfactory sensitivity. The present study focuses on the state of sadness in n = 31 healthy subjects in order to investigate the specific contribution of this affective state in the modulation of olfactory processin…
Basic emotions elicited by odors and pictures
The sense of olfaction is often reported to have a special relationship with emotional processing. Memories triggered by olfactory cues often have a very emotional load. On the other hand, basic negative or positive emotional states should be sufficient to cover the most significant functions of the olfactory system including ingestion, hazard avoidance, and social communication. Thus, we investigated whether different basic emotions can be evoke…
