摘要

以往使用不同粗糙度的砂纸作为目标和干扰物进行触觉搜索的研究表明,当目标和干扰物的角色颠倒时,细砂纸中的粗糙砂纸会 "跳出来",并能在更短的时间内搜索到目标和干扰物。然而,还不清楚胶囊纸上触觉符号的形状差异是否也会导致同样的搜索不对称。为了探究这种可能性,我们进行了一项触觉搜索实验,使用胶囊纸上有圆点或没有圆点的圆作为目标和干扰物,这些圆经常被用作盲人触觉图中的点符号。与我们的预期相反,这两种触觉符号之间并没有出现触觉搜索不对称现象。无论目标类型如何,搜索时间都会随着项目(干扰项加目标项)数量的增加而增加,因为参与者倾向于采用串行搜索策略,即每次找到一个新的触觉符号时,他们都会将食指或中指放在该触觉符号上进行区分。目标不存在与目标存在试验的搜索时间之比,与重复搜索试验的发生率精确吻合。

Haptic search asymmetry does not occur due to different-shaped tactile symbols on capsule paper.

Previous research on haptic search using sandpaper with different roughness levels as a target and distractors showed that rough sandpaper among fine "pops out" and can be searched for in a shorter time than when the roles of the target and distractors are reversed. However, it is not clear whether the same search asymmetry occurs with differences in the shapes of tactile symbols on capsule paper. To explore this possibility, we conducted a haptic search experiment using circles with or without a dot on capsule paper as a target and distractors, which are often used as point symbols in tactile maps for the blind. Contrary to our expectations, haptic search asymmetry did not occur between these two tactile symbols. Regardless of target type, the search times increased in proportion to the number of items (distractors plus target), as participants tended to adopt serial search strategy in which they placed their index or middle finger on the tactile symbol to distinguish it every time they found a new one. The ratio of the search times for target-absent to target-present trials is precise alignment with the occurrence rate of repetitive search trials.
