Seven-month-old Vivi is presented with a trapezoidal object that adults would perceive as a rectangle placed on a diagonal, with one side closer than the other side, similar to the window from the Yonas, Cleaves, and Pettersen study described in the text. During the first set of trials, a patch is placed over one eye, and the object is presented in front of Vivi. During the second set of trials, the patch is removed and the object is again presented. Researchers record Vivi's reaches toward the object. The MOST likely result will be that Vivi reaches
A) toward the longer side on both sets of trials.
B) toward the longer side on the first set of trials but equally toward both sides on the second set of trials.
C) equally toward both sides on the first set of trials but toward the longer side on the second set of trials.
D) toward the longer side when viewed with one eye closed.

When one eye is covered, Vivi will have difficulty perceiving depth and may use other cues, such as the relative length of the sides of the object, to guide her reach. Since the longer side will appear closer, she is likely to reach toward it with one eye closed. When the patch is removed and depth perception is restored, Vivi is more likely to reach based on the object's position in space rather than the length of the sides, resulting in no preference between the two sides.
