Premium gas Vs performance

I inadvertently put half a tank's worth of high octane gas in my Elantra recently. I normally use basic unleaded so I guess I wound up with an octane somewhere in between. The odd thing was I seemed to notice the car having a bit more pickup afterward. I'm wondering if my mind is playing tricks to make me feel better (for having a duh moment) or if the higher octane might make a little difference...?
