这项研究的目的是通过四个实验来验证一系列视觉刺激(线段)将被主观感知为视线或表面的条件。用主观评价线段的方法进行了两个实验,另外两个具有奥斯古德语义差异。我们分析了五个变量(厚度,type,定位,和颜色)可能负责线路分类。四个实验给出了类似的结果:变量厚度和类型的重要性更高;可变颜色的一般意义较低;可变方向的一般意义不大。有趣的是,对于变量类型,直线比曲线更频繁地被评估为表面,并被感知为几何形状,扁平,硬,静态,粗糙,锋利,绑定,酸,寒冷,男性,冷和被动。曲线被普遍评价为线,并归类为有机的,圆形,软,动态,蓬松,钝,免费,甜,感性的,女性化,温暖和活跃。这些结果突出了所考虑变量的感知特征的特异性,并证实了诸如厚度和类型之类的变量特征的相关性。
The aim of this study is to verify the conditions under which a series of visual stimuli (line segments) will be subjectively perceived as visual lines or surfaces employing four experiments. Two experiments were conducted with the method of subjective evaluation of the line segments, and the other two with the Osgood semantic differential. We analysed five variables (thickness, type, orientation, and colour) potentially responsible for the lines\' categorisation. The four experiments gave similar results: higher importance of the variables thickness and type; general lower significance of the variable colour; and general insignificance of the variable orientation. Interestingly, for the variable type, straight lines are evaluated as surfaces more frequently than curved lines and perceived as geometrical, flat, hard, static, rough, sharp, bound, sour, frigid, masculine, cold and passive. Curved lines are prevalently evaluated as lines, and categorised as organic, rounded, soft, dynamic, fluffy, blunt, free, sweet, sensual, feminine, warm and active. These results highlight the specificity of perceptual characteristics for the considered variables and confirm the relevance of the characteristics of variables such as thickness and type.
