Researchers at Texas A&M University, led by Annmarie MacNamara, investigated whether emotional reactions to mistakes predict later avoidance. They worked with 74 people who reported symptoms of anxiety, depression, PTSD, or OCD. The design measured brain activity immediately after an error and then repeated the measurement one year later, allowing the team to compare initial reactions with later change.
A central finding focused on a pattern called blunting — a decline in the brain's emotional response to errors over time. Individuals who reacted strongly to errors at the first visit and then showed blunting over the following year tended to become more avoidant of uncomfortable situations. MacNamara links this pattern to increased anxiety symptoms in those people.
The authors suggest the results could help clinicians understand why symptoms get worse for some people but not others, and they point to potential biological signals, or biomarkers, that might eventually inform diagnosis and more targeted treatments. The research appears in the journal Biological Psychiatry Global Open Science.

Dopamine helps lock in new skills during sleep
A study from the University of Michigan finds that dopamine neurons become active during NREM sleep soon after a person learns a movement. Their activity, together with sleep spindles, strengthens motor memories and improves skills after sleep.
