Suppose you visit a child development laboratory and observe a researcher working with an 8-month-old baby. The baby is sitting on top of a piece of Plexiglas, which rests partly over a table top and then extends out over the end of the table. The apparatus being used in this experiment is typically called a:
A) visual cliff
B) binocular challenge
C) visually guided grid
D) perceptual challenge map

The visual cliff is an apparatus commonly used in developmental psychology to assess infants' depth perception abilities. It typically consists of a glass top over a checkered pattern, creating the illusion of a sudden drop-off. Infants are placed on the glass and encouraged to crawl towards a visual stimulus (usually a toy) placed at different distances either on the shallow or deep side of the cliff. Since the glass is transparent, the infant must use depth cues to determine whether to traverse the cliff or not.
