Abstract

Despite longstanding philosophical and psychological intrigue in self-talk, relatively little empirical research has explored its influence on decision-making nor decision confidence. The present study employs a between-subjects experimental design to investigate how covert and overt self-talk influence confidence during novel decision-making tasks. Participants will assume the role of a professional in a fictional field and complete decision-making scenarios while engaging in either covert (internal) self-talk, overt (external) self-talk, articulatory suppression, or natural decision-making behavior (control). We hypothesize that both covert and overt self-talk will increase self-reported decision confidence, whereas articulatory suppression will reduce confidence relative to the control. Additionally, we predict that individual differences in self-talk propensity, measured using the Self-Talk Scale (STS), will moderate the relationship between self-talk condition and confidence. Exploratory thematic analyses will also examine how self-talk condition influences risk assessment and other behaviors. Given the ubiquity of self-talk in daily life, further investigation into its role as a metacognitive regulatory mechanism may yield valuable insights across a wide range of psychological domains and significantly advance our understanding of the human experience.
