Brain Imaging

Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

Interference and Decay

Interference and Decay

Forgetting is a complex cognitive phenomenon influenced by several factors, among which interference and decay are particularly prominent. These processes explain why individuals often struggle to retrieve specific information from memory, leading to lapses in recall that can be observed in everyday situations.
Interference occurs when competing memories hinder the retrieval of particular information. It can be classified into two types: proactive and retroactive interference. Proactive...

Area of Science:

Cognitive Neuroscience
Neuroplasticity
Human Lifespan Development

Background:

Information interference negatively impacts task goal achievement.
External and internal interferences possess distinct neural signatures.
Neural processing differs based on whether interference is suppressed or engaged with.

Purpose of the Study:

Develop a framework for understanding interference impact on neural systems.
Investigate how interference regulation and suppression occur during on-task performance.
Examine lifespan changes in interference processing and develop targeted interventions.

Main Methods:

Review of a decade of research on cognitive and neural processing of interference.
Comparison of interference processing across younger adults, older adults, children, and cognitively impaired populations.
Development and evaluation of three novel cognitive training interventions targeting interference resolution.

Main Results:

Established a cognitive framework for interference processing and its neural underpinnings.
Demonstrated distinct neural signatures for external versus internal interference.
Cognitive training interventions showed success in improving interference resolution and generalizing benefits to other cognitive control abilities in healthy aging.

Conclusions:

An in-depth understanding of neural mechanisms of interference resolution can inform effective interventions.
Cognitive training based on neuroplasticity principles can improve interference resolution.
These interventions show promise for benefiting both healthy and cognitively impaired populations.
