Former goalkeeper Chamberlain, who played 50 times for England, said Shiels had to take responsibility for “knowing the value that words can hold”.
“I think we all know that the five minutes after you concede a goal – not just in women’s football, [also] in men’s football – you’re more likely to concede a goal,” she told BBC Radio 5 Live.
“To just generalise that to women is a slightly bizarre comment.
“When you give post-match news conferences when you’re feeling emotional after a big game, it’s important to make sure that you are speaking sensibly and are aware of the message that your words can carry.”
Wright tweeted that Shiels was “talking foolishness”.
England went 1-0 up in the 26th minute but had to wait until the 52nd minute to add a second.
“When we went 1-0 down we tried to slow it down to give them time to get that emotional imbalance out of their heads. That’s an issue we have,” Shiels added.
“Not just in Northern Ireland but all of the countries in the world.”
Northern Ireland were playing in front of a crowd of 15,348 at Windsor Park in Belfast – a record for a women’s match in the country.
The Irish Football Association has been approached for comment.
