Psychophysical data suggest that spatial resolution and spatial position sensitivity may be limited by different neural mechanisms. We investigated this hypothesis from a developmental perspective by studying the development of these two kinds of visual performance in two groups of infant macaque monkeys (Macaca nemestrina), one normal and one given an experimental strabismus. The results show that these two visual functions develop at different rates in normal monkeys and are disrupted differentially by abnormal early visual experience. However the relationship between the two measures is the same in strabismic and normally reared monkeys; the performance of strabismic monkeys resembles that of younger normal monkeys.
心理物理学数据表明，空间分辨率和空间位置敏感度可能受不同神经机制的限制。我们从发育的角度对这一假设进行了研究，观察了两组婴猴（豚尾猕猴）这两种视觉能力的发育情况，一组为正常婴猴，另一组为实验性斜视婴猴。结果显示，在正常猴子中，这两种视觉功能以不同速率发育，且早期视觉异常经历对它们的干扰也有所不同。然而，斜视猴子和正常饲养猴子的这两种测量指标之间的关系是相同的；斜视猴子的表现类似于年幼的正常猴子。
