England have crashed out of major tournaments on spot-kicks on five occasions in the last 22 years.
Hodgson: "We have used the time after training sessions to regularly practise and we'll obviously take it even more seriously now.
"You hope one day it will make a big difference.
"But you can practise penalty shoot-outs until the cows come home, it's really your composure, your confidence, your ability to really block everything out and forget the occasion that means you score or don't.
"Sometimes we've seen the best players miss and the ones you think are not penalty takers are the ones that smash them in.
"It's going to be that way because we've lost important matches on penalties..
"When you are working with the England national team the past is always going to weigh heavily because everything we do today is being compared with something that before.
"Unfortunately we have lost two very important semi-finals on penalties so I presume that's going to be there during all my time as national coach. Probably when a national coach comes 20 years hence he will be asked the same question as well."
