Interactions between two different visual patterns, a coarse grating and a fine texture pattern, were investigated in the context of velocity aftereffects in human subjects. The perceived velocity shift, in which the perceived velocity of a moving test pattern is reduced following exposure to a similarly moving adaptation pattern, is apparent when the adaptation and test patterns are of the same or different types. The aftereffect transfers interocularly in both cases. The directional tuning of the aftereffect is broad, and has a different profile for texture adaptation than for bar adaptation. When adaptation is to a composite stimulus comprising independently moving bars and texture, the aftereffect varies according to the nature of the test pattern. The results are discussed with reference to interactions between the responses of neurones in feline striate cortex to the two types of pattern.
在人类受试者速度后效的背景下，研究了两种不同视觉模式——粗光栅和精细纹理模式之间的相互作用。当适应模式和测试模式相同或不同时，就会出现感知速度偏移，即移动的测试模式在暴露于类似移动的适应模式后，其感知速度会降低。在这两种情况下，后效都会在两眼间转移。后效的方向调谐范围很广，纹理适应的后效轮廓与条形适应的不同。当适应的是由独立移动的条形和纹理组成的复合刺激时，后效会根据测试模式的性质而变化。本文参照猫纹状皮层中神经元对这两种模式的反应之间的相互作用对结果进行了讨论。
