Resumen

La percepción de la imagen corporal comprende características representativas estables y dinámicas. Aquí examinamos si una medida estable de la imagen corporal (IC) correlaciona con el senso de agencia (SA) de movimientos corporales. Un total de 21 estudiantes universitarios (M=25,9, DP=9,29) completaron la versión brasileña de la Escala de Figuras de Siluetas (EFS) y participaran en el Experimento de la Mano Alienígena. Una matriz de correlación bayesiana reveló una probabilidad de correlación negativa sustancial entre IC y la confianza en SA, específicamente en las condiciones experimentales donde el SA fue manipulado. Con base en los escores de la EFS, los participantes se dividieron en grupos con y sin evidencias de distorsión de IC. Las comparaciónes de grupos evidenciaron una diferencia sustancial entre los grupos. Los análisis confirmaron una menor confianza en SA entre individuos con distorsión de IC mayor que ±3 kg/m².
