Illusory vertical gratings (V) and diagonal gratings (D) can be seen on a uniform field after inspection of a vertical grating. When using simultaneous and successive matching techniques the spatial frequencies of the V effect were found to be about 2 octaves below and 1-2 octaves above the adapting spatial frequency, but to be invariant with temporal frequency. At high adapting frequencies the D effect dominated, and was about 0.8 octave below the adapting spatial frequency, oriented about +/-35 degrees from vertical. The apparent contrast of V was about twice the value of the contrast threshold at its apparent spatial frequency. D effects seen during adaptation were about 60 degrees from vertical and 3 octaves below the adapting frequency. The results are interpreted in terms of inhibition and disinhibition in an organized matrix of tuned channels, and the dominant pattern of inhibition in the matrix is inferred. Supporting evidence from neurophysiology, neuroanatomy, and psychophysics is briefly reviewed. An appendix deals with the question of interocular transfer of the aftereffect.
在观察垂直光栅之后,在均匀视场上可以看到虚幻的垂直光栅(V)和对角光栅(D)。当使用同时匹配和相继匹配技术时,发现V效应的空间频率在适应空间频率以下约2个八度和以上1 - 2个八度,但与时间频率无关。在高适应频率下,D效应占主导,并且在适应空间频率以下约0.8个八度,与垂直方向成约+/- 35度角。V的表观对比度约为其表观空间频率下对比度阈值的两倍。适应期间看到的D效应与垂直方向成约60度角,且在适应频率以下3个八度。结果根据调谐通道的有组织矩阵中的抑制和去抑制来解释,并推断出矩阵中抑制的主导模式。简要回顾了来自神经生理学、神经解剖学和心理物理学的支持证据。附录讨论了后效的双眼间转移问题。
