PT42 S4 No.5

Postby mz253 » Sat Sep 18, 2010 5:40 pm

I chose C instead of A.

I eliminated A because of "innate" since the stimulus says "hours after birth,"

I chose C because I guess if infants relate human faces with comfort and nourishment, that's why they stare at them LONGER?

But the correct answer is A. Can anyone help me here?

Here's my take on it:

What we need to explain is how or why would infants be able to distinguish faces from other images. (A) provides a reason -- if the skill is innate, it explains why infants, hours after birth, already have this characteristic. "Innate" is actually what makes this argument work!

(B) is out of scope - we're not talking about whether an infant finds it interesting. If the faces are more interesting and that's why the infants stare at them, than it's not because they're faces, it's because they're interesting!

(C) is incorrect because it doesn't explain why an infant - hours after birth - would know the difference. It would explain why they might start to do this later on, after they learned the connection.

(D) is similar to (B) in that it focuses on preference, not the ability to distinguish.

(E) is similar to (C) -- it's something that would have to be learned.
