Answer
Personality neuroscience is an emerging field that aims to understand the neurobiological systems that underlie persistent individual differences in emotion, motivation, cognition, and behavior. This field of study focuses on the persistent psychological individual differences, typically in the general population. The main goals of personality neuroscience are to understand the mechanisms of the brain that influence personality and to understand how both genetic and environmental forces create these mechanisms. To achieve these goals, researchers use a variety of tools and methods, including magnetic resonance imaging (MRI), electroencephalography (EEG), and pharmacological assays and manipulations, to measure individual differences in the structure and function of the brain. Personality neuroscience is a young field, due to the relatively recent invention of much of its measurement technology, but it is growing rapidly. It seeks to bridge the gap between personality psychology and neuroscience, aiming to provide a more comprehensive understanding of personality traits and their neural implementation. Research in this field often involves looking for statistically significant correlations between brain structure/activity and individual personality traits. These correlations help researchers understand the positive and negative differences between personality traits and models. Despite its youth and the challenges it faces, researchers are optimistic about the future of personality neuroscience. They believe that it will provide valuable insights into the neurobiological causes and correlates of individual differences, and contribute to our understanding of how our brains influence our natural behaviors.
