We conducted preregistered replications of 28 classic and contemporary published findings, with protocols that were peer reviewed in advance, to examine variation effect magnitudes across samples settings. Each protocol was administered approximately half 125 comprised 15,305 participants from 36 countries territories. Using the conventional criterion statistical significance ( p < .05), we found 15 (54%) provided evidence a statistically significant same direction as original finding....

Are emotional expressions shaped by specialized innate mechanisms that guide learning, or do they develop exclusively from learning without preparedness? Here we test whether nonverbal affective vocalisations produced bilaterally congenitally deaf adults contain information is recognisable to naive listeners. Because these individuals have had no opportunity for auditory the presence of such an association would imply mappings between emotions and vocalizations are buffered against absence...
In a double-blind experiment, participants were exposed to facial images of anger, disgust, fear, and neutral expressions under 2 body odor conditions: fear sweat. They had indicate the valence gradually emerging image. Two alternative hypotheses tested, namely "general negative evaluative state" hypothesis "discrete emotion" hypothesis. These suggest distinctive data patterns for muscle activation classification speed expressions. The pattern results that would support emotions perspective"...
Thankfully, most people feel good of the time, and we often spontaneously show our positive feelings to others. Yet scientific understanding how express emotions is largely based on posed displays. Here, empirically test 22 are expressed face using participant-negotiated episodic recall method. European respondents (n = 163) narrated emotional events from their lives (data collected 2018 2020). Frequency analyses extracted facial expressions (67, 279 datapoints) mostly supported...
Nonverbal vocalisations like “Ew!” and “Ugh!” are often used to communicate disgust. While disgust evolved primarily promote the avoidance of pathogens (pathogen disgust), it is also expressed toward moral violations (moral disgust). In this study, we investigated whether pathogen acoustically distinct listeners can differentiate between them. We conducted machine learning analyses acoustic parameters two preregistered listening experiments (all in 2023) test these questions. Based on a...
Laughing is ubiquitous in human life, yet what causes it and how sounds highly variable. Considering this diversity, we sought to test whether there are fundamentally different kinds of laughter. We sampled spontaneous laughs from wide range everyday situations (n = 887). Machine learning analyses showed that produced during tickling acoustically distinct triggered by other events (verbal jokes, watching something funny, or witnessing someone else’s misfortune). A listening study 210)...
Momentary emotional experiences constitute a key ingredient of psychological wellbeing. Here, we examine the role for wellbeing during prolonged stress COVID-19 pandemic. Study 1 compared relative importance before versus pandemic using pre-registered analyses with representative samples. Negative were more detrimental and positive less protective 2 examined specific survey data from 24,221 participants in 51 countries. feelings calm, hope, anxiety, loneliness, sadness were, across...
Vocalizations linked to emotional states are partly conserved among phylogenetically related species. This continuity may allow humans accurately infer affective information from vocalizations produced by chimpanzees. In two pre-registered experiments, we examine human listeners' ability behavioural contexts (e.g. discovering food) and core affect dimensions (arousal valence) 155 66 chimpanzees in 10 different positive negative at high, medium or low arousal levels. experiment 1, listeners (...
Laughter is a ubiquitous social signal. Recent work has highlighted distinctions between spontaneous and volitional laughter, which differ in terms of both production mechanisms perceptual features. Here, we test listeners' ability to infer group identity from as well the perceived positivity these laughs across cultures. Dutch ( n = 273) Japanese 131) participants listened decontextualized laughter clips judged (i) whether laughing person was their cultural in-group or an out-group; (ii)...
The COVID-19 pandemic presents challenges to psychological well-being, but how can we predict when people su er or cope during sustained stress?Here, test the prediction that specific types of momentary emotional experiences are di erently linked well-being pandemic.Study 1 used survey data collected from 24,221 participants in 51 countries outbreak.We show that, across countries, is individuals' recent experiences, including calm, hope, anxiety, loneliness, and sadness.Consistent results...
Abstract The human voice communicates emotion through two different types of vocalizations: nonverbal vocalizations (brief non-linguistic sounds like laughs) and speech prosody (tone voice). Research examining recognizability emotions from the has mostly focused on either or prosody, included few categories positive emotions. In preregistered experiments, we compare listeners’ (total n = 400) recognition performance for 22 ( 880) to that 880). results show listeners were more accurate in...
When we hear another person laugh or scream, can tell the kind of situation they are in – for example, whether playing fighting? Nonverbal expressions theorised to vary systematically across behavioural contexts. Perceivers might be sensitive these putative systematic mappings and thereby correctly infer contexts from others' vocalisations. Here, two pre-registered experiments, test prediction that listeners accurately deduce production (e.g. being tickled, discovering threat) spontaneous...
Laughing is ubiquitous in human life, yet what causes it and how sounds highly variable. Considering this diversity, we sought to test whether there are fundamentally different kinds of laughter. Here, sampled spontaneous laughs ( n = 887) from a wide range everyday situations (e.g. comedic performances playful pranks). Machine learning analyses showed that produced during tickling acoustically distinct triggered by other events (verbal jokes, watching something funny or witnessing someone...
Around the globe, people are living under threat of COVID-19 pandemic, and many experiencing curtailed opportunities for sustainable livelihoods real-world social interactions. These conditions present a significant challenge to wellbeing1,2 it is therefore essential examine factors associated with psychological wellbeing during this pandemic other collective crises3. Here, we used survey data collected from 26,684 participants in 51 countries 17 April 15 May 2020 individual societal that...
The complexity of human behaviour presents a challenge for behavioural scientists. We propose that scientific understanding can be accelerated by large-scale computational studies in everyday life. Specifically, we taking ethology approach. Ethology pioneered the systematic study real-world settings early 20th century; recent advances methods allow such to scaled up. Computational uses video and audio recordings establish how, when, why specific behaviours are elicited ecologically relevant...
In behavioural contexts like fighting, eating, and playing, acoustically distinctive vocalisations are produced across many mammalian species. Such expressions may be conserved in evolution, pointing to the possibility of acoustic regularities phylogenetically related Here, we test this hypothesis by comparing degree similarity between human chimpanzee 10 similar contexts. We use two complementary analysis methods: Pairwise distance measures separability metrics based on unsupervised...
What can evolutionary theories tell us about emotions, and how research on emotions inform theories? In this chapter, we discuss links between of emotion the cross-cultural study emotion. We examine what predictions be derived from consistency variability. particular, emphasise notion that evolved psychological mechanisms result in cultural differences instantiated as variations common themes human universals. focus two components emotions: experience nonverbal expressions.
