This study investigates vocalized hesitations, specifically filled pauses, in the spontaneous speech of individuals with varying levels of introversion and extroversion. The primary objective is to examine the potential correlation between psychotype and the frequency of vocalized hesitations, thereby elucidating distinct speech patterns associated with introversion and extroversion. Through a rigorous analysis of statistical data and correlation measures, this study aims to contribute to our understanding of the intricate interplay between personality traits and verbal communication. Research suggests that introverts tend to exhibit a higher rate of vocalized hesitations, possibly serving as cognitive processing strategies during speech production. In contrast, extroverts are hypothesized to display fewer vocalizations and prioritize more fluid speech output, reflecting their inclination for externalized thought processes. By uncovering the underlying mechanisms of vocalized hesitations and their relationship to introversion and extroversion, this research enhances our knowledge of how psychotypes manifest in spontaneous speech. The findings have implications for psycholinguistic theories and provide valuable insights for researchers and practitioners working in the fields of psychology, communication sciences, and psycholinguistics.
