Linda Acredolo Placed Babies in a Room Where They Were

Linda Acredolo placed babies in a room where they were trained to turn in one direction, say left, to make an interesting display appear in a window. The window was either marked with a big star or left unmarked. After learning to turn left to make the display appear, the babies were rotated 180 degrees. What would we conclude if the babies responded correctly in the new trials (they turned right) , regardless of whether the window was marked by a star or not?

A) The babies used the landmark to help locate the window with the interesting display.
B) The babies did not need to use the landmark to help locate the window with the interesting display.
C) The babies were responding with reference to their own bodies.
D) Babies are not equipped to use landmarks to help with these kinds of tasks.
