THE EFFECT OF CHANGING SIZE OF RDS ON THE PLASTICITY OF STEREOPSIS
立体图对的尺寸变化对立体感可塑性的影响

In order to study the effect of different spatial parameters of RDS on the plasticity of stereopsis, three sets of psychophysical experiments were conducted under the following stimulus conditions.The first one was changing the size of one of two-half pictures of RDS in both horizontal and vertical directions. The second was changing of the size in horizontal direction and the third was changing of the size in vertical direction.The results showed that when the size of one half-picture of RDS was changed in different directions, the limitations of plasticity of stereopsis (LPS) were significant. The LPS was the smallest in the first experiment, the LPS was the largest in the second experiment and the LPS is middle in the third experiment.For 3 sizes of RDS, the effect of their size on the LPS was not significant.
