"Attraction to men and women predicts sexual dimorphism preferences"
"Attraction to men and women predicts sexual dimorphism preferences"
International Journal of Sexual Health
International Journal of Sexual Health
We investigated women’s (N = 27,611) preferences for sexual dimorphism in male faces in relation to self-reports of sexual attraction to men/women (from ‘not at all’ to ‘very’). We found that self-identified heterosexual women reported considerable variation in sexual attraction levels. We also found that sexual dimorphism preferences related positively with attraction to men and negatively with attraction to women.

"Sex Differences in Mate Preferences Across 45 Countries: A Large-Scale Replication"
Psychological Science
Psychological Science
Using a 45-country sample (N = 14,399), we attempted to replicate classic studies on human mate preferences and test both the evolutionary and biosocial role perspectives. Support for universal sex differences in preferences remained robust: Men, more than women, preferred attractive, young mates, and women, more than men, preferred older mates with financial prospects. Cross-culturally, both sexes had mates closer to their own ages as gender equality increased.

Cosmetics
Many studies have examined how defendant characteristics influence jury decisions, but none have investigated the effect of cosmetics. In this study, we therefore examined how cosmetics influence jury decisions for young and middle-aged female defendants.

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 this study, my students and I surveyed local waterways for the presence of Aphanomyces astaci, a species of oomycete that is responsible for devastating crayfish plague in Europe. Previous studies have suggested that A. astaci is native to North America, and was accidentally introduced to Europe along with asymptomatic crayfish. We were able to confirm the presence of A. astaci locally, and suggest that environmental damage and the introduction of invasive species may impact the natural resistance of native crayfish to this disease.

"Language, habit and the future"
Habits: Pragmatist Approaches from Cognitive Science, Neuroscience, and Social Theory
Habits: Pragmatist Approaches from Cognitive Science, Neuroscience, and Social Theory
I draw from Dewey's account of habit in juxtaposition with the enactive philosophy of linguistic bodies to consider three key features about human language, working to locate linguistic practice fully in body–environment interactions and habits that arise therein. A deep connection between language, habit, and environment is needed now, I argue, because as humans we must tell ourselves, and we must believe, that habits can change, and that what is exceptional about our kind of being can be good and not only deadly for the rest of the universe.

Inflated lava flows grow vertically through a combination of initially rapid molten core thickening and gradual crustal accretion. The McCartys lava flow field includes a series of interconnected lava‐rise plateaus that formed via inflation over the course of years. Recognizing products of inflation on Earth and other planetary bodies can constrain lava emplacement processes and eruption timescales

We evaluated the role of local and watershed-scale stream habitat variables and stream flow conditions to understand the factors associated with survival of age-0 Smallmouth Bass in Ozark streams. Age-0 bass were most abundant in deeper, warmer streams and following benign July stream flows, though these relationships were dampened or absent in close proximity to larger mainstem rivers.

Contrary to previous studies demonstrating HIV disclosure as a tool to improve medication adherence among perinatally HIV infected adolescents, the findings of our study demonstrate that the improvement in medication adherence is maintained for a brief period followed by a significant decline. Our findings suggest healthcare institutions provide additional counseling and support services to adolescents as they learn of their positive HIV status.

We investigated whether storybooks and direct instruction can influence children's preferences to distribute resources either equally or based on merit. While storybooks with animals didn't change children's resource distribution preferences, direct instruction reliably altered children's resource distribution preferences. Matched storybooks and direct instruction featuring humans produced similarly strong changes.

Remarkably preserved clusters of chaetae (bristles), never before seen as features of a living or extinct snail, are described in association with the earliest documented fossil snails, about 512 million years old, from Lancaster County. These chaetae confirm the prior inference, based on molecular data from living organisms, that molluscs, annelid worms, and brachiopods ("lamp shells") share an ancient common ancestry.

Pyramidal neurons of the prefrontal cortex in rhesus monkeys undergo many structural and functional changes during normal aging, but the effects of these changes on working memory performance is not understood fully. Our differential equations-based computational model simulates two spatial working memory tasks, and shows how a loss of synaptic connections and an increase in electrical excitability of pyramidal neurons observed in aging can lead to cognitive impairment.

Two studies demonstrate that White Americans have difficulty imagining middle-class Black space as desirable and high quality, and the stronger this difficulty, the more likely they are to devalue a house in a Black neighborhood. These findings have implications for place-based racial disparities, such as residential segregation and environmental racism.
