通过训练转移设计，研究了训练对观察者检测三点错位、超敏锐度和分辨六线光栅的能力的影响（两个实验各有 4 名观察者），这些观察者在对其他视觉刺激进行心理物理学判断方面经验丰富。 培训转移设计使我们能够寻找任何基于培训的改进。 在任何条件下，长时间的训练都不会产生统计上显着的表现改善。 基于实践有一些小的改进，但主要模式表明阈值波动而不是改进。 我们对结果的解释表明，三点对齐和光栅辨别的神经机制，如间隙平分的神经机制（Klein & Levi，1985），没有任何显着程度的可塑性。
The effect of training on an observer's ability to detect the misalignment of three points, a hyper-acuity, and to resolve a six-line grating was studied in a transfer-of-training design with observers (4 in each of two experiments) who were experienced in making psychophysical judgments of other visual stimuli. The transfer-of-training design enabled us to look for any training-based improvement. Long periods of training produced no statistically significant improvement in performance under any condition. There were small practice-based improvements, but the primary patterns indicated threshold fluctuation rather than improvement. We interpret the results to indicate that the neural mechanisms underlying three-point alignment and grating discrimination, like those for gap bisection (Klein & Levi, 1985), are not malleable to any significant extent.
