Implied odds when an Ace completes your straight

[emerson]

I used to count my implied odds as a little better when an ace completed the straight, thinking that it could make aces for an oppoenent who may now be more likely to call or raise. It was suggested to me that the opposite was true. The ace that makes the straight is more likely to scare away opponents who have paired and are now afraid of the ace.

Is there any correct logic either way and should implied odds be factored any differently when an ace completes your straight?
