A preferential-looking procedure was used to investigate newborns' responses to square-wave gratings varying in spatial frequency and contrast. A preliminary study confirmed that the gratings used in the experiment were suprathreshold. In the experiment newborns' preference for a grating of 0.1 cycle deg-1 within the peak contrast sensitivity range was examined. Reduction in the contrast of this grating led to a transfer of the preference to a high-contrast grating of the same space-averaged luminance with a spatial frequency outside this range (0.42 cycle deg-1). The findings are discussed with reference to the role of the contrast sensitivity function in pattern preferences of newborns: it is suggested that contrast and spatial frequency interact in determining pattern preferences.
采用偏好注视程序来研究新生儿对空间频率和对比度不同的方波光栅的反应。一项初步研究证实，实验中使用的光栅是阈上的。在实验中，研究了新生儿在峰值对比度敏感度范围内对0.1周/度的光栅的偏好。该光栅对比度的降低导致偏好转移到具有相同空间平均亮度、空间频率超出此范围（0.42周/度）的高对比度光栅上。结合对比度敏感度函数在新生儿图案偏好中的作用对这些发现进行了讨论：研究表明，对比度和空间频率在决定图案偏好方面相互作用。
