Narcissus reflected: Grey and white matter features joint contribution to the default mode network in predicting narcissistic personality traits
Abstract
The article investigates how both grey and white matter in the brain contribute to narcissistic personality traits through their roles in the default mode network (DMN). Using advanced imaging and machine learning techniques, the study identifies specific brain features linked to narcissism, providing insights into the neural basis of these traits.
Explanation
Here are the key points from the article:
- Research Focus: Examines the joint contribution of grey and white matter features in the brain to the default mode network (DMN) and their role in predicting narcissistic personality traits.
- Methodology: Utilizes advanced neuroimaging techniques and machine learning to analyze brain scans.
- Findings: Identifies specific brain features associated with narcissism, highlighting the significant role of the DMN.
- Implications: Provides new insights into the neural underpinnings of narcissistic traits, suggesting that both grey and white matter characteristics contribute to these personality features.
Figure 1. Method. After preprocessing, GM and WM images were entered a data fusion unsupervised machine learning approach (p-ICA), to decompose the brain into joint GM-WM independent networks. Then stepwise regression and Random Forest regression were used to predict narcissistic personality traits.
