Emotions key to judging others

A new study suggests that emotions are crucial for making moral judgments. Patients with damage to the ventromedial prefrontal cortex (VMPC) have difficulty responding emotionally to hypothetical situations and may judge others' actions as morally permissible even if they intended harm.

Easily grossed out? You might be a conservative!

Two Cornell University studies found a correlation between being more easily disgusted and political conservatism, particularly in attitudes toward gays and lesbians. Disgust sensitivity was linked to opposition to gay marriage and abortion, but not to other issues.

The 2 worlds of kids' morals

Research reveals marked gender and race differences in children's moral behaviors, both in the real and virtual worlds. African American children were more likely to view morally questionable virtual behaviors as acceptable when they benefited individual goals.

U of T psychologists shed light on origins of morality

A study by U of T psychologists reveals a connection between moral disgust and primitive emotions related to poison and disease. The research found that people display similar facial movements in response to both moral and primitive forms of disgust.

The more you take the more you lose

A study by Boaz Keysar and colleagues found that negative reciprocity, or taking, escalates in social exchanges, leading to irrational feuds. In contrast, acts of giving are perceived as more generous, encouraging pro-social exchanges.

Just look: When it comes to art, viewing may be as satisfying as buying

A new study by Yu Chen found that buying and viewing art share similar benefits, including the desire for aesthetics, sociality, and novelty. Collectors and visitors to galleries share common values but differ in their motivations, with collectors seeking a long-term intimate relationship with artworks.

Group selection, a theory whose time has come ... again

David Sloan Wilson and Edward O. Wilson propose a new consensus and theoretical foundation for sociobiology, affirming Darwin's original conjecture that natural selection is a multilevel process. They show that adaptations can evolve at all levels of the biological hierarchy, from genes to ecosystems.

What does it mean to have a mind? Maybe more than you think

Researchers found that people perceive the minds of others along two distinct dimensions: agency (self-control, morality) and experience (feelings, sensations). This framework sheds light on moral and legal decisions and highlights the subjective nature of perceiving mental attributes in others.
