Glass patterns (GPs) have been widely employed to investigate the mechanisms underlying processing of global form from locally oriented cues. The current study aimed to psychophysically investigate the level at which global orientation is extracted from translational GPs using the tilt after-effect (TAE) and manipulating the spatiotemporal properties of the adapting pattern. We adapted participants to translational GPs and tested with sinewave gratings. In Experiment 1, we investigated whether orientation-selective units are sensitive to the temporal frequency of the adapting GP. We used static and dynamic translational GPs, with dynamic GPs refreshed at different temporal frequencies. In Experiment 2, we investigated the spatial frequency selectivity of orientation-selective units by manipulating the spatial frequency content of the adapting GPs. The results showed that the TAE peaked at a temporal frequency of ∼30 Hz, suggesting that orientation-selective units responding to translational GPs are sensitive to high temporal frequencies. In addition, TAE from translational GPs peaked at lower spatial frequencies than the dipoles’ spatial constant. These effects are consistent with form-motion integration at low and intermediate levels of visual processing.

玻璃图案（GPs）已被广泛用于研究从局部提示中处理全局形式的机制。当前的研究旨在从心理学角度研究使用倾斜后效应（TAE）从平移GP中提取全局取向的水平，并操纵适应模式的时空特性。我们使参与者适应了平移GP，并通过正弦波光栅进行了测试。在实验1中，我们调查了方向选择单元是否对自适应GP的时间频率敏感。我们使用了静态和动态转换GP，并以不同的时间频率刷新了动态GP。在实验2中，我们通过操纵自适应GP的空间频率内容来研究方向选择单元的空间频率选择性。结果表明，TAE在约30 Hz的时间频率处达到峰值，表明响应翻译GP的方向选择单元对高时间频率敏感。此外，来自平移GP的TAE在比偶极子的空间常数低的空间频率处达到峰值。这些效果与低级和中级视觉处理中的形体运动整合是一致的。
