Researchers have found that, hours after birth, infants are able to distinguish faces from other images. Infants stare at drawings of face for longer periods of time than they do at blank ovals or drawings in which facial features are scrambled.
Which one of the following, if true, most helps to explain the ability of newborn infants described above?
(A) Certain abilities of facial pattern recognition are innate in humans, rather than learned
(B) The longer an infant stares at an object, the more interesting the infants finds the object
(C) infants learn to associate humans face with the necessities of comfort and nourishment
(D) The less an infant stares at an object, the weaker the preference the infant has for that object
(E) Infants learn to associate the sound of human voices with the images of human faces
Source: LSATThe stimulus states that researchers have found that infants can distinguish faces from other images just hours after birth. As evidence, the stimulus states that infants stare are drawings of faces for longer periods than they do at similar non-face images.
The question stem asks you to explain how newborn infants would be able to make this distinction.
Answer choice (A): This is the correct answer choice. If facial recognition is innate, then infants are born with the ability to recognize faces.
Answer choice (B): This answer does not address how the infants distinguish the faces from other images, and it does not explain why they stare at the faces for longer periods than they do at the scrambled face images.
Answer choice (C): If infants learn to make the association stated in this answer choice, then they would need time to make that association. Thus, this answer cannot explain why infants can recognize faces just hours after birth.
Answer choice (D): This answer is similar to answer choice (B). This answer does not address how the infants distinguish the faces from other images, and it does not explain why they stare at the faces for longer periods than they do at the scrambled face images.
Answer choice (E): If infants learn to make the association stated in this answer choice, then they would need time to make that association. Thus, this answer cannot explain why infants can recognize faces just hours after birth.
