Songs tell a story: The Arc of narrative for music.

Research suggests that a core lexical structure characterized by words that define plot staging, plot progression, and cognitive tension underlies written narratives. Here, we investigate the extent to which song lyrics follow this underlying narrative structure. Using a text analytic approach and two publicly available datasets of song lyrics including a larger dataset (N = 12,280) and a smaller dataset of greatest hits (N = 2,823), we find that music lyrics tend to exhibit a core Arc of Narrative structure: setting the stage at the beginning, progressing the plot steadily until the end of the song, and peaking in cognitive tension in the middle.

Status-impact assessment: is accuracy linked with status motivations?

Status hierarchies are ubiquitous across cultures and have been over deep time. Position in hierarchies shows important links with fitness outcomes. Consequently, humans should possess psychological adaptations for navigating the adaptive challenges posed by living in hierarchically organised groups.

Niche Diversity Predicts Personality Structure Across 115 Nations.

The niche-diversity hypothesis proposes that personality structure arises from the affordances of unique trait combinations within a society. It predicts that personality traits will be both more variable and differentiated in populations with more distinct social and ecological niches. Prior tests of this hypothesis in 55 nations suffered from potential confounds associated with differences in the measurement properties of personality scales across groups.

Mate Availability and Sexual Disgust.

Objective: One of the factors that sexual disgust should be calibrated to is the size of the mating pool. This study tested this hypothesis by examining whether perceptions of mate availability explain variance in levels of sexual disgust towards potential mates.

Methods: Participants ( = 853; 373 women) rated how sexually disgusting they found 60 potential mates that have previously been rated on attractiveness by a separate group of raters.

Psychological foundations of human status allocation.

Competing theories of status allocation posit divergent conceptual foundations upon which human status hierarchies are built. We argue that the three prominent theories of status allocation-competence-based models, conflict-based models, and dual-pathway models-can be distinguished by the importance that they place on four key affordance dimensions: benefit-generation ability, benefit-generation willingness, cost-infliction ability, and cost-infliction willingness. In the current study, we test competing theoretical predictions about the relative centrality of each affordance dimension to clarify the foundations of human status allocation.

Human status criteria: Sex differences and similarities across 14 nations.

[Correction Notice: An Erratum for this article was reported online in on Sep 7 2020 (see record 2020-68801-001). In the original article, the third sentence in the Content level subsection in the Status Criteria More Central to Women section of the Results should appear instead as , and increase women's status more than men's. A coding error in Figure 7 for Dishonoring Family appeared.

Men's Bodily Attractiveness: Muscles as Fitness Indicators.

Bodily attractiveness is an important component of mate value. Musculature-a crucial component of men's bodily attractiveness-provides women with probabilistic information regarding a potential mate's quality. Overall musculature is comprised of several muscle groups, each of which varies in information value; different muscles should be weighted differently by attractiveness-assessment adaptations as a result.
