The researchers discovered that those who were unhappy before the hurricane saw the largest jumps in satisfaction.
The study found that memories of objects from stressful situations rely on similar brain activity as memories of the stress trigger itself. This suggests that the mechanism reinforcing emotional memories is rooted in the neural link between important aspects of the episode and the stress trigger.
Researchers found that lower performing students reported higher stress levels due to multiple factors, including work obligations, feeling like they don't belong, or lack of confidence. The study suggests that successful interventions should target multiple areas of student stress.
