Researchers used HurryDate speed dating events to study human mating behavior, finding that physical appearance and personality traits dominate decision-making. Contrary to expectations, financial factors like income and education played a negligible role in attraction.
A recent linguistics study found that people from different cultures use varying numbers of emotion words, with a greater emphasis on negative emotions. The researchers discovered that older adults tend to have more diverse vocabularies when describing their emotional experiences.
A recent study by Robert Kurzban and Daniel Houser found that three main personality types play a crucial role in group projects: Reciprocators, Cooperators, and Free Riders. The study revealed that about 63% of participants are Reciprocators, who tend to hold back before fully committing to a project.
Babytalk plays a crucial role in infants' development of temporal arts, such as literature and music. Depriving babies of poetic elements like alliteration and assonance may hinder their ability to appreciate these arts later on. Researchers argue that babytalk is more significant than previously thought.
Wen-Hsiung Li has made seminal contributions to the field of evolutionary molecular genetics, developing widely used methods for inferring phylogenetic relationships and discovering important insights into genetic change rates. His work has improved our understanding of evolutionary lineages and genetic diversity.
A recent study published in Personality and Social Psychology Review by Christine Harris questions the evolutionary theory of sex differences in jealousy. She finds that men and women view sexual and emotional jealousy in a similar light, with many studies failing to account for individual variability and cultural influences. Harris su...
Stanford biologists Paul R. Ehrlich and Marcus W. Feldman critique genetic determinism in their essay, arguing that human behavior is shaped by environmental factors rather than genes. They also challenge the concept of heritability, pointing out its limitations in predicting human behaviors.
A study by Northeastern University's David DeSteno reveals that both men and women experience more distress from sexual than emotional infidelity. The findings challenge long-held evolutionary theories on jealousy.
