A researcher is studying the visual abilities of a 3-day-old infant. The infant is shown four different images, one at a time, for the same duration. The researcher records how long the infant looks at each image. Based on typical newborn sensory development, which image is the infant most likely to gaze at for the longest period?

A researcher is studying the visual perception of one-day-old newborns. In the experiment, two images are displayed side-by-side in front of each infant: one is a simple, black-and-white line drawing of a human face, and the other is a black-and-white image of a complex, abstract pattern with similar contrast and brightness. An eye-tracker measures the amount of time each infant spends looking at each image. Which of the following results would you most likely expect from this study?
