A meta-analysis of 170 studies found a consistent link between mental effort and discomfort across diverse populations and tasks. Interestingly, this aversive effect was less pronounced in Asian countries, possibly due to different cultural attitudes towards education. Despite the discomfort, people still engage in challenging tasks for potential rewards, indicating that the motivation may lie in the benefits rather than the effort itself.

Stress May Boost Helping Behavior When Witnessing Injustice

A new study finds that acute stress experienced while witnessing injustice can make people more likely to help victims rather than punish offenders. This shift in behavior is linked to increased activity in the dorsolateral prefrontal cortex (DLPFC), a brain region involved in decision-making. The findings suggest that helping others may be a more intuitive response than punishing them, especially under stress.
