The Transition to Compulsion in Addiction?Insights from Personality Traits, Psychodynamics, and Neurobiology

Dr. Haodong Su

Compulsion stands as a central symptom of drug addiction; however, only a small fraction of drug users exhibit compulsive characteristics. Differences observed in Sign-trackers (ST) and Goal-trackers (GT) during Pavlovian conditioning may shed light on individual variances in drug addiction. Here, we focus on the behavioral attributes, formation processes, and neural mechanisms underlying ST and how they drive addiction towards compulsivity in humans. We will explore addiction from three interconnected levels: individual personality traits, psychodynamics, and neurobiology. Furthermore, we distinguish between the processes of sensitization and habituation within ST. These nuanced distinctions across various aspects of addiction will contribute to our understanding of the addiction development process and the formulation of targeted preventive strategies.
