However, it is unclear whether these processes reflect stable vulnerability markers or symptoms of psychopathology, as most research relies on cross-sectional correlations and few longitudinal studies assess their predictive role in anxiety. Furthermore, little is known about the test-retest reliability of fear learning paradigms, despite their suggested function as trait-like markers for anxiety.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>This longitudinal study reassesses initially healthy adults after 3–12 years, and children first examined at ages 8–12, then 12–16, and now at 16–22. Participants repeat the “screaming lady” paradigm, including fear acquisition and generalization.
