Lines contribute to the visual experience of drawings. People show a higher preference for curved than sharp angled lines. We studied preference for curvature using drawings of commonly-used objects drawn by design students. We also investigated the relationship of that preference with drawing preference. Experiments 1 and 2 revealed preference for the curved drawings in the laboratory and web-based contexts, respectively. Experiment 3 showed that the curved drawings were also preferred to draw than the sharp-angled ones. However, this effect only appeared when the drawings were made by hand, but not when they were made by computer. We found a moderate positive correlation between liking and drawing preference. This relationship was mainly explained by the hand-made drawings. Sex, art experience and openness to experience did not influence preference for curvature. Altogether, our findings support the curvature effect and the hypothesis that people prefer to draw what they like to see.

线条有助于绘画的视觉体验。人们对曲线的偏好比对锐角线的偏好更高。我们使用设计专业学生绘制的常用物体的图纸研究了对曲率的偏好。我们还研究了这种偏好与绘画偏好的关系。实验 1 和 2 分别显示了在实验室和基于网络的环境中对曲线图的偏好。实验 3 表明，弯曲的图画也比锐角的图画更受欢迎。但是，这种效果只有在手绘时才会出现，而在计算机制作时则不会出现。我们发现喜欢和绘画偏好之间存在适度的正相关。这种关系主要是通过手绘来解释的。性别，艺术经验和对经验的开放性并没有影响对曲率的偏好。总而言之，我们的研究结果支持曲率效应和人们更喜欢画他们喜欢看到的东西的假设。
