Three experiments tested whether geometric biases--biases away from perceived reference axes--reported in spatial recall tasks with pointing responses generalized to a recognition task that required a verbal response. Seven-year-olds and adults remembered the location of a dot within a rectangle and then either reproduced its location or verbally selected a matching choice dot from a set of colored options. Results demonstrated that geometric biases generalized to verbal responses; however, the spatial span of the choice set influenced performance as well. These data suggest that the same spatial memory process gives rise to both response types in this task. Simulations of a dynamic field model buttress this claim. More generally, these results challenge accounts that posit separate spatial systems for motor and verbal responses.
三项实验测试了在空间回忆任务中报告的几何偏差——远离感知参考轴的偏差，这些偏差通过指向反应表现出来，是否会推广到需要言语反应的识别任务中。7岁儿童和成年人记住矩形内一个点的位置，然后要么重现其位置，要么从一组彩色选项中口头选择一个匹配的选择点。结果表明，几何偏差推广到了言语反应中；然而，选择集的空间跨度也会影响表现。这些数据表明，在这项任务中，相同的空间记忆过程产生了两种反应类型。动态场模型的模拟支持了这一观点。更普遍地说，这些结果挑战了那种为运动和言语反应设定单独空间系统的观点。
