Distract yourself or think it over? 2 ways to deal with negative emotions

A new study published in Psychological Science finds that people use two main strategies to regulate their emotions: distraction and reappraisal. When faced with low-intensity negative emotions, individuals tend to reappraise the situation by thinking through it, while high-intensity emotions trigger a distracting response.

Why do hopeful consumers make healthier choices than happy ones?

A new study published in the Journal of Consumer Research found that hopeful consumers are more likely to choose healthy snacks like fruit over unhealthy options like candy bars. The authors suggest that this is because hopeful individuals focus on the future, rather than dwelling on past experiences or present emotions.

From terror to joy: faced with death, our minds turn to happier thoughts

Researchers found that when individuals contemplate death, their unconscious mind actively seeks out and activates pleasant memories to cope with the threat. This 'terror management theory' suggests that the brain protects itself from paralyzing fear by involuntarily searching for positive associations.
