The present research addresses the question of the "oblique effect" (better discrimination of the vertical orientation than of an oblique orientation) in manual haptic perception of orientations (without visual control) by 5-month-old infants. A familiarization/reaction to novelty procedure was used. The results revealed the occurrence of a haptic oblique effect. These findings are similar to those obtained in infant visual perception. We suggest that 5-month-old infants predominately use vertical orientation as a reference norm to perceive haptically spatial orientations. We discuss the implications of these results for both orientation processing and anatomofunctional level contributing specifically to the haptic oblique effect.
本研究探讨了5个月大婴儿在无视觉控制的情况下对手动触觉方向感知中“倾斜效应”（垂直方向比倾斜方向的辨别能力更强）的问题。采用了熟悉/对新奇事物的反应程序。结果揭示了触觉倾斜效应的存在。这些发现与婴儿视觉感知中获得的结果相似。我们认为，5个月大的婴儿主要以垂直方向作为参考标准来触觉感知空间方向。我们讨论了这些结果对方向处理以及对触觉倾斜效应有特殊贡献的解剖功能水平的影响。
