相对于纸质阅读，盲文阅读的手指运动速度更加恒定，与所有单词进行连续且详尽的接触。然而，运动的连续性以两种不同的方式是间歇性的：（a）读者改变方向并重新阅读已经遇到的材料；（b）加速和减速阶段之间速度的连续波动。我们分析了有经验的读者遇到模棱两可的句子的记录，预计会鼓励更多的逆转，并对阅读过程中的手指运动进行比较运动学分析。数据表明，逆转何时开始以及逆转的目标反映了语言处理的需求。然而，它们的运动学特性与前读的运动学特性没有本质上的不同。我们得出的结论是，盲文读者如何向前和向后移动阅读手指主要受低速运动的控制特性的影响，其次受语言特性的影响。
Relative to print reading, braille-reading finger movements are held to be of more constant speed, with continuous and exhaustive contact with all words. However, the continuity of movements is intermittent in two distinct ways: (a) readers reverse direction and reread material already encountered and (b) the continual fluctuations of velocity between phases of acceleration and deceleration. We analyze recordings of experienced readers' encounters with ambiguous sentences predicted to encourage more reversals, and we undertake comparative kinematic analyses of the finger movements during such reading. The data suggest that when reversals are initiated and where they are targeted reflect language-processing demands. However, their kinematic properties are not qualitatively different from those of forward reading. We conclude that how readers of braille move the reading finger-both forward and in reverse-is primarily influenced by the control properties of low-velocity movements and only secondarily by language properties.
