一个审查给出了一组实验的性能作为显示角度的函数，旨在描述的感知策略与信号在不同的角度间隔。第一个实验使用简单的四项选择辨别任务进行。结果表明，作为显示角度的函数的性能的非线性下降，这被证明是有关的必要性，使眼睛和头部运动时，从一个信号源转移到其他。提出了选择加工的非线性是由于策略的变化引起的，并提出了一个关于选择加工的初步理论，并在一些任务中得到了检验
A review is given of a group of experiments on performance as a function of display angle, aiming at a description of the perceptual strategies used with signals at various angular separations. The first experiments were carried out using a simple four-choice discrimination task. The results show a non-linear decrease of performance as a function of display angle, which proved to be related to the necessity of making eye and head movements when shifting from one signal source to the other. It is suggested that the non-linearity is due to changes of strategy and a preliminary theory about selective processes is formulated and tested in a number of tasks
