An investigation of tactile picture perception is reported. Blindfolded sighted subjects explored either 'line drawings' or 'textured' tactile pictures produced on Zytex swell paper. All pictures were 'two-dimensional', that is they depicted only one object face and so did not represent a third dimension. Both picture sets represented the same objects. Results revealed that the textured pictures, in which solid surfaces of depicted objects were uniformly textured, were recognised more often than tactile line drawings, in which surfaces of objects were simply bounded by lines. There were no significant correlations between imagery ability (visual, cutaneous, or kinaesthetic) and picture recognition success. Texture may be a form of 'uniform connectedness' (Palmer and Rock 1994 Psychonomic Bulletin & Review 1 29-55) or 'common region' (Palmer 1992 Cognitive Psychology 24 436-447), highlighting the global characteristics of stimuli. We argue that textured pictures may encourage the haptic system to take a more globally oriented approach to tactile picture perception, benefiting recognition.
本文报告了一项关于触觉图像感知的研究。蒙眼的视力正常受试者探索了在Zytex膨胀纸上制作的“线条画”或“有纹理的”触觉图像。所有图像都是“二维的”，也就是说它们只描绘了一个物体的面，因此没有呈现出三维效果。两组图像描绘的是相同的物体。结果显示，与物体表面仅由线条界定的触觉线条画相比，描绘物体的实体表面具有均匀纹理的有纹理图像被识别的次数更多。意象能力（视觉、皮肤觉或动觉）与图像识别成功率之间没有显著相关性。纹理可能是“均匀连通性”（帕尔默和罗克，1994年，《心理onomic通报与评论》第1卷，第29 - 55页）或“共同区域”（帕尔默，1992年，《认知心理学》第24卷，第436 - 447页）的一种形式，突出了刺激的全局特征。我们认为，有纹理的图像可能会促使触觉系统在触觉图像感知中采取更具全局导向性的方法，从而有利于识别。
