Questions: A developmental psychologist is interested in the visual abilities of newborn children. Baby Katherine is participating in a study of newborns' visual abilities. While her mother holds Katherine, a psychologist shows the baby a variety of images. Of these images, which will Katherine look at the longest? a zebra a human face a box of matches a hammer

The answer is the second one (or B): a human face.

Explanation for each option:

• A zebra: While the contrasting stripes of a zebra might catch a newborn's attention, it is not as compelling as a human face.
• A human face: Newborns have a natural preference for looking at human faces. This preference is believed to be an evolutionary trait that helps them bond with their caregivers and learn social cues.
• A box of matches: This object is relatively plain and lacks the complexity and familiarity of a human face, making it less interesting to a newborn.
• A hammer: Similar to the box of matches, a hammer is not as visually stimulating or familiar to a newborn as a human face.

Summary: Newborns are naturally inclined to look at human faces longer than other objects due to their innate preference for faces, which aids in social bonding and development. Therefore, Baby Katherine will look at the human face the longest.
