["The Journal of Creative Behavior, Volume 60, Issue 2, June 2026. ", "\nABSTRACT\nCreative cognition research has flourished in recent decades, revealing how extraordinary creative outcomes emerge from ordinary cognitive processes. However, the field faces fragmentation that hinders consensus and integration. This research agenda, developed through a collaborative workshop of 50 European researchers at the Lorentz Centre in Leiden, the Netherlands, identifies four critical challenges for advancing creative cognition research. Challenge 1 addresses theoretical concerns around defining core research terms like divergent thinking, emotions, and metacognition. Challenge 2 focuses on identifying different types and domains of knowledge that influence creative performance. Challenge 3 emphasizes measuring dynamic interactions between cognitive, affective, and metacognitive processes over time. Challenge 4 calls for incorporating environmental and interpersonal contexts, including collaboration, technology, and embodied cognition. These challenges highlight the need for collaborative approaches to develop standardized measures, synthesize existing findings, and foster methodological innovations. By working together as a research community, we can build more comprehensive theories and effective methods for understanding creativity's cognitive foundations while embracing rather than reducing its inherent complexity.\n"]
