Globally, songs and instrumental melodies are slower and higher and use more stable pitches than speech: A Registered Report

Science Advances, Journal Year: 2024, Volume and Issue: 10(20)

Published: May 15, 2024

Both music and language are found in all known human societies, yet no studies have compared similarities differences between song, speech, instrumental on a global scale. In this Registered Report, we analyzed two datasets: (i) 300 annotated audio recordings representing matched sets of traditional songs, recited lyrics, conversational melodies from our 75 coauthors speaking 55 languages; (ii) 418 previously published adult-directed song speech 209 individuals 16 languages. Of six preregistered predictions, five were strongly supported: Relative to songs use higher pitch, slower temporal rate, (iii) more stable pitches, while both used similar (iv) pitch interval size (v) timbral brightness. Exploratory analyses suggest that features vary along "musi-linguistic" continuum when including lyrics. Our study provides strong empirical evidence cross-cultural regularities speech.

Love songs and serenades: a theoretical review of music and romantic relationships

Frontiers in Psychology, Journal Year: 2024, Volume and Issue: 15

Published: Feb. 14, 2024

In this theoretical review, we examine how the roles of music in mate choice and social bonding are expressed romantic relationships. Darwin’s Descent Man originally proposed idea that musicality might have evolved as a sexually selected trait. This proposition, coupled with portrayal popular musicians sex symbols prevalence love-themed lyrics music, suggests possible link between attraction. However, recent scientific exploration evolutionary functions has predominantly focused on theories group signaling, limited research addressing sexual selection hypothesis. We identify two distinct types music-making for these different functions: attraction, which would be virtuosic nature to display physical cognitive fitness potential mates; connection, facilitate synchrony partners likely engage same reward mechanisms seen general synchrony-bonding effect, enhancing perceived interpersonal intimacy facet love. Linking musical psychological relationship development components love, present model outlines relationships, from initial attraction ongoing maintenance. addition synthesizing existing literature, our serves roadmap empirical aimed at rigorously investigating

The "Bench Dragon" Motion Trajectory Model Based on the Spiral Equation

Highlights in Science Engineering and Technology, Journal Year: 2025, Volume and Issue: 136, P. 70 - 78

Published: March 31, 2025

Dragon dancing, a vital aspect of traditional Chinese folk art, has evolved through the integration modern technology and mathematical models. This study investigates motion characteristics dragon dance teams, addressing five critical questions about their complex trajectories. Initially, trajectory equation equidistant spiral was established, Fourth-Order Runge-Kutta algorithm, alongside bisection method, facilitated high-precision analysis team's over 300 seconds, calculating key positions velocities. To determine termination moment entry, bench collision model developed to ensure safety under varying spatial conditions. Additionally, optimizing minimum pitch improved performance's smoothness, while modeling arc radius as decision variable reduced area speed needed for dragon's movement. A scheme enhance head also proposed, enriching visual appeal performance. research offers fresh insights into patterns promotes innovation in culture.

The Influence of Mating Context on Creativity: Insights from Simulated Dating Scenarios

Evolutionary Psychology, Journal Year: 2025, Volume and Issue: 23(2)

Published: April 1, 2025

Creativity offers both survival and reproductive benefits, being a desirable trait in potential mates linked to fertility sexuality. We investigated whether viewing attractive faces of short-term or long-term partners simulated dating portal enhances participants’ creativity. also explored possible mediators (arousal, mood, sexual arousal, motivation, attraction) moderators (relationship status, satisfaction, mate value, sociosexual orientation). In Study 1, 483 participants ( M age = 30.06, SD 6.37; 242 women, 241 men) viewed either four unattractive opposite-sex wrote self-promotional bios. No significant creativity differences were found between the groups. However, men more flexible produced original ideas than while women showed greater fluency self-creativity promotion. 2, 494 30.84, 6.06; 258 236 profiles for inclined relationships. Women's originality higher condition, but arousal negatively impacted when choosing an partner relationship, particularly real date desirability with was high. Overall, results suggest that is influenced by mating context, though effects modest. Future studies should increase sample sizes, geographic diversity, experimental settings.

How music-induced emotions affect sexual attraction: evolutionary implications

Frontiers in Psychology, Journal Year: 2024, Volume and Issue: 15

Published: April 10, 2024

More than a century ago, Darwin proposed putative role for music in sexual attraction (i.e., sex appeal), hypothesis that has recently gained traction the field of psychology. In his writings, particularly emphasized charming aspects music. Across broad range cultures, profound impact on humans' feelings, thoughts and behavior. Human mate choice is determined by interplay several factors. A number studies have shown musicality ability to produce enjoy music) exert positive influence evaluation potential partners. Here, we critically review latest empirical literature how why affect considering music-induced emotion arousal listeners as well other socio-biological mechanisms. Following short overview current theories about origins musicality, present examine different social settings. We differentiate between emotion-based influences related subjective experience sound effects associated with perceived musical or creativity partner. By integrating using various behavioral methods, link research strands investigate suggest promising avenues future research.

Bases ecológicas e evolutivas do comportamento humano

Published: May 27, 2024

Este livro foi pensado para ser um primeiro texto didático e introdutório às bases ecológicas evolutivas do comportamento humano, voltado o ensino ao nível de graduação. Porém, este também pode útil aqueles entrando na pós-graduação, especialmente vindos áreas sem muita tradição pesquisa ecológica evolutiva. Embora cada capítulo possa lido em qualquer ordem, organizamos modo que a sequência sugerida, vai geral mais específico, permita aprofundamento gradual dos diferentes conceitos disciplinas dedicadas aos estudos ecológicos evolutivos da mente humana.
