Although objects with curved contours are generally preferred over those with sharp-angled contours, the strength of this preference varies according to several factors. In the present study, non-Western Japanese observers viewed and rated their preferences (e.g., or ) for real and meaningless objects with curved or sharp-angled contours. We varied the presentation time (90 ms vs. until a response was received) and the response measure (like/dislike vs. 1-100 rating scale). When using like/dislike ratings, a preference for curved objects was found only when images of real objects were presented briefly (90 ms), whereas this effect was reversed (i.e., increased preference for sharp-angled contours) when using the 1 to 100 scale under the until-response condition. In addition, the curvature effect was not observed for real objects when the like/dislike rating and the until-response condition were employed or when the 1 to 100 scale and 90 ms presentation time were used. The curvature effect for meaningless objects remained unstable regardless of presentation time or response measure. Similar to the preference for real objects, a preference for sharp-angled objects was observed when preference was measured using a 1 to 100 rating scale. Taken together, the present findings indicate that the preferences for curved objects were situation-dependent in Japanese observers.
尽管通常人们更喜欢轮廓弯曲的物体而非轮廓有尖角的物体，但这种偏好的强度会因几个因素而有所不同。在本研究中，非西方的日本观察者观看并对具有弯曲或尖角轮廓的真实和无意义物体的偏好进行评分（例如，喜欢/不喜欢或1 - 100评分量表）。我们改变了呈现时间（90毫秒与直到收到反应）和反应测量方式（喜欢/不喜欢与1 - 100评分量表）。当使用喜欢/不喜欢评分时，只有在短暂呈现真实物体图像（90毫秒）时才发现对弯曲物体的偏好，而在直到反应条件下使用1到100量表时，这种效应则相反（即对尖角轮廓的偏好增加）。此外，当采用喜欢/不喜欢评分和直到反应条件时，或者当使用1到100量表和90毫秒呈现时间时，未观察到真实物体的曲率效应。无论呈现时间或反应测量方式如何，无意义物体的曲率效应都不稳定。与对真实物体的偏好类似，当使用1到100评分量表测量偏好时，观察到对尖角物体的偏好。综上所述，目前的研究结果表明，日本观察者对弯曲物体的偏好取决于具体情境。
