193: The Pathologist's Eye: Exploring Templates and Perception with Claudia Mello-Thoms

Understanding Visual Perception in Medical Diagnoses: A Deep Dive with Claudia Mello-Thoms

In this episode, Christine continues the conversation with Claudia Mello-Thoms, an expert in visual perception as it relates to medical diagnosis. The discussion delves into the use of templates by experts to quickly recognize abnormalities in medical images, despite their large size and complexity. Claudia explains how perception operates at a subconscious level, often leading to perceptual errors in medical practices like radiology and pathology. The conversation underscores the need to understand the human element in diagnostics to reduce errors and improve accuracy. The episode also explores the difference between rapid (fast) and deliberative (slow) processing in the assessment of medical images, emphasizing the importance of fresh perspectives when diagnostic clarity is lacking.
