The effect of inducing stimuli on the luminance of a brief test stimulus (2.5'-wide line) required to match the brightness of a comparison stimulus was measured at various stimulus onset asynchronies (SOAs). Assuming that the test brightness is determined by the peak response to the test stimulus, the difference in the test brightness in the absence and in the presence of an inducing stimulus as a function of the SOA was employed as a measure of the temporal response to the inducing stimulus. The temporal responses to brief decremental inducing stimuli (a 2.5'-wide line and a 30'-wide bar) consisted of three oscillations, the middle one being the largest. The triphasic form of the temporal impulse responses was confirmed by measuring the temporal step responses to these stimuli. The step responses consisted of alternating positive and negative phases which might be regarded as a temporal analogue of the Mach bands in space. The data obtained were described by a model of the weighting function which was assumed to be a spatiotemporal Gabor-like function.
在不同的刺激起始异步时间（SOA）下，测量了诱导刺激对匹配比较刺激亮度所需的短暂测试刺激（2.5'宽的线条）亮度的影响。假设测试亮度由对测试刺激的峰值响应决定，将无诱导刺激和有诱导刺激时测试亮度随SOA的差异用作对诱导刺激时间响应的度量。对短暂递减诱导刺激（2.5'宽的线条和30'宽的条带）的时间响应由三次振荡组成，中间的振荡最大。通过测量对这些刺激的时间阶跃响应，证实了时间脉冲响应的三相形式。阶跃响应由交替的正相和负相组成，这可以被视为空间中马赫带的时间类似物。所获得的数据由一个加权函数模型描述，该模型被假定为时空类伽柏函数。
