When drivers are distracted or upset, their brain's automatic error correction system helps them stay on course, but texting significantly disrupts this process.
A new UCL study found that bad experiences are strongly remembered, but surrounding context is weakly recalled due to reduced activity in the hippocampus. This imbalance can lead to strong but fragmented memory for traumatic content, contributing to post-traumatic stress disorder symptoms.
Research on neural network interactions and related brain activity patterns provides insights into thought processes that make people vulnerable to depression. The study identifies increased activity in one important brain network, called the default mode network, which may contribute to maladaptive rumination.

In a study, MS patients showed more severe moral judgments than average, even in neutral conditions, attributing negative emotions to external causes. This 'externally oriented thinking' helps them minimize damage but also leads to an inability to reflect on emotions and identify real causes of their negative emotional state.
A recent study examined the relationship between empathy and understanding others' mental states. The findings suggest that people who tend to be empathic do not necessarily understand other people well at a cognitive level. Social skills seem to be based on multiple abilities that are independent of each other.
A new study found that bi-dialectal children exhibited similar cognitive advantages as multilingual children, including improved memory, attention, and cognitive flexibility. The research suggests that the ability to switch between two dialects of the same language provides mental stimulation and leads to higher cognitive performance.
