Memory for location of a dot inside a circle was investigated with the circle in the center of a computer screen (Experiment 1) or with the circle presented in either the left or the right visual field (Experiment 2). In both experiments, as in Huttenlocher, Hedges, and Duncan's (1991) study, the task was to relocate the dot by marking the remembered location. When errors in angular and radial estimates were considered separately, it was found that, in both experiments, the angular locations of estimates of the dots' positions regressed toward different locations inside each quadrant of the circle; the radial locations of the estimates of dots' positions tended to regress toward locations near the circumference. These variations in the direction of bias appeared to reflect a general shift of estimates toward the upper left arc of the circle. The second experiment replicated the preceding effects but also revealed that the regressions within quadrants of angular values were stronger after right visual field that after left visual field presentations. We interpret the dissociation between visual fields as evidence that memory for categorical spatial relations (Kosslyn, 1987) is more dependent on left-hemisphere than on right-hemisphere processing.
研究了对圆内点位置的记忆，在实验1中，圆位于电脑屏幕中央；在实验2中，圆出现在左视野或右视野。在这两个实验中，与赫滕洛彻、赫奇斯和邓肯（1991年）的研究一样，任务是通过标记记忆中的位置来重新定位点。当分别考虑角度和径向估计中的误差时，发现在这两个实验中，点位置估计的角度位置在圆的每个象限内向不同位置回归；点位置估计的径向位置倾向于向圆周附近的位置回归。偏差方向的这些变化似乎反映了估计向圆的左上弧的总体偏移。第二个实验重复了上述效应，但也表明，在右视野呈现后，角度值象限内的回归比左视野呈现后更强。我们将视野之间的分离解释为证据，表明对分类空间关系的记忆（科斯莱因，1987年）更多地依赖于左半球处理而非右半球处理。
