    El objetivo de este estudio fue investigar si existe una relación entre el diámetro pupilar y el atractivo facial. Participaron en la estudio 60 adultos jóvenes (30 hombres y 30 mujeres) entre 18 y 26 años de edad (M = 20.65, DE = 2.20). Se utilizaron como estímulos diez rostros neutrales desconocidos diferentes (cinco hombres y cinco mujeres). El diámetro de la pupila de cada cara se manipuló con diámetros de pupila de 2, 3, 4, 5 y 6 mm (10 caras x 5 diámetros de pupila = 50 estímulos). Se realizó un estudio en dos etapas con la misma muestra y los mismos conjuntos de caras buscando entender la diferencia de respuestas entre sujetos de ambos sexos. En la fase I, el resultado indicó una diferencia significativa en relación al factor de diámetro de la pupila tanto para los hombres (ꭓ² = 21.93, p <0.05) como para las mujeres (ꭓ² = 44.73, p < 0.05). En la fase II, los resultados indicaron diferencias significativas en relación al tamaño de la pupila [F (1, 234) = 19,06, p < 0,05]. La prueba post-hoc de Tukey HSD mostró que tanto los hombres como las mujeres evaluaron de manera diferente las caras con un diámetro pupilar de 2 mm con respecto a las caras con diámetros pupilares de 3, 4, 5 y 6 mm (p < 0,05). Se observó una diferencia significativa entre el diámetro de 5 mm en relación al diámetro de 3 mm (p < 0,05). En general, los resultados indican que el diámetro de la pupila es un componente estructural de la cara humana que desempeña una importante función en el proceso de juicio del atractivo facial.

Participated in the study 60 young adults (30 men and 30 women) between 18 and 26 years of age (M = 20.65, SD = 2.20). Ten different unfamiliar neutral faces (five men and five women) were used as stimuli. The pupil diameter of each face was manipulated with pupil diameters of 2, 3, 4, 5 and 6 mm (10 faces x 5 pupil diameters = 50 stimuli). A two-step study was carried out with the same sample and the same sets of faces, seeking to understand the difference of responses between subjects of both sexes. In phase I, result indicated a significant difference in relation to the pupil diameter factor for both the men (ꭓ² = 21.93, p < .05) and the women (ꭓ² = 44.73, p < .05). In phase II, the results indicated significant differences in relation to the pupil size [F (1, 234) = 19.06, p < 0.05]. The post hoc Tukey HSD test showed that both the men and the women differently judged the faces with a pupil diameter of 2 mm in relation to the faces with pupil diameters of 3, 4, 5 and 6 mm (p < .05). Also, a significant difference between the diameter of 5 mm in relation to the diameter of 3 mm (p < .05). In general, the results indicate that the pupil diameter is a structural component of the human face that plays an important role in the process of judging facial attractiveness.
