Hypothesis
Older adults with amnestic mild cognitive impairment exhibit differences in conflict monitoring compared to cognitively healthy controls.
Conclusion
The study found that individuals with amnestic MCI were slower and less accurate in conflict tasks compared to healthy controls, indicating alterations in conflict processing.
Supporting Evidence
- The MCI group took longer to respond and was less accurate than the HC group on mismatched trials.
- Both groups were less accurate when responding to mismatched versus matched trials.
- Preliminary analysis showed different patterns of neural oscillatory activity between the two groups.
Takeaway
Older people with mild memory problems have a harder time when faced with tricky tasks compared to those without memory issues.
Methodology
The study used a picture-word interference paradigm with EEG to assess behavioral performance and neural activity in MCI and healthy control groups.
Participant Demographics
27 individuals with amnestic MCI (average age 75.3) and 27 cognitively healthy controls (average age 72.6).
