Yes, they learn the second syntax from birth.  There have been arguments to teach the lisp syntax in mathematics due to it being easier to understand with multiple arguments:<p><pre><code>    (+ x y z a) instead of (x + y + z + a)
</code></pre>
Also, there are no order of operations problems with the lisp syntax like there are with traditional mathematical notation (unless you use parens, which makes it look even more lispy).
