Design-trained subjects sorted fourteen solid forms under either visual or haptic conditions into groups on the basis of perceived similarity of balance or along a balance continuum. After these tasks of coarse and fine discrimination, each form was rated on ten bipolar stimulus attributes. Multidimensional scaling and property-fitting analyses were performed on the results of four experiments to determine the combined contribution of stimulus attributes and level of discrimination on the visual and haptic percept of balance. A balance dimension emerged for both modalities, but only when subjects were inclined to attend globally to the structure of a form by the coarse-discrimination task. Results indicate that visual balance is a holistic property of forms which derives from the synthesis of physical stimulus information. For touch, subjects appear to have equated balance with a symmetric distribution of weight/shape about the central axis of a form. Findings are related to theoretical notions of balance.
接受过设计训练的受试者在视觉或触觉条件下，根据感知到的平衡相似性或沿着平衡连续体，将十四种实体形状分类成组。在完成这些粗略和精细辨别任务后，对每种形状在十个双极刺激属性上进行评分。对四个实验的结果进行了多维标度和属性拟合分析，以确定刺激属性和辨别水平对视觉和触觉平衡感知的综合贡献。两种模态都出现了一个平衡维度，但只有当受试者倾向于通过粗略辨别任务全面关注形状的结构时才会出现。结果表明，视觉平衡是形状的一种整体属性，它源自物理刺激信息的综合。对于触觉而言，受试者似乎将平衡等同于形状围绕中心轴的重量/形状对称分布。研究结果与平衡的理论概念相关。
