Caricaturing Shapes in Visual Memory
通过六个实验（700名成人）发现，即使对简单几何形状，记忆也会自动夸大其显著特征（如曲率、突出部分），且这种漫画化偏差在无任务要求时也会发生。
When representing high-level stimuli, such as faces and animals, we tend to emphasize salient features—such as a face’s prominent cheekbones or a bird’s pointed beak. Such mental caricaturing leaves traces in memory, which exaggerates these distinctive qualities. How broadly does this phenomenon extend? Here, in six experiments ( N = 700 adults), we explored how memory automatically caricatures basic units of visual processing—simple geometric shapes—even without task-related demands to do so. Participants saw a novel shape and then immediately adjusted a copy of that shape to match what they had seen. Surprisingly, participants reconstructed shapes in exaggerated form, amplifying curvature, enlarging salient parts, and so on. Follow-up experiments generalized this bias to new parameters, ruled out strategic responding, and amplified the effects in serial transmission. Thus, even the most basic stimuli we encounter are remembered as caricatures of themselves.
