The Canaries were thumped 5-1 by Liverpool in midweek, but Hooper was on target along with Leroy Fer on Saturday to earn them a valuable win.
Hooper scored the opener in the 13th minute, firing a right-footed drive into the bottom corner, before Dutchman Fer sealed all three points which helped them leapfrog their opponents in the Premier League table.
"The gaffer told us to forget about the result (in midweek) because we have a big game against West Brom," the 25-year-old told Sky Sports.
"He told us to go out, play and do what you can do.
"There was one point between us in the table but now we're two points ahead of them.
"We defended well and John (Ruddy) was outstanding. We took our chances."
The former Celtic man now feels he has fully recovered from the shin injury which blighted his summer following his big-money move.
"It's not nice getting injured at the start of the season, but the medical team sorted me out and it's going well. I have scored a few goals now."
