Higdon scored his 25th goal of the season with a penalty five minutes after the break as Motherwell came from behind to secure a place in Europe next season.
And when he was asked if the prospect of Europa League football could influence his decision, Higdon said: "Definitely.
"I'm not sure what I'm doing next year, but playing in front of a decent crowd, playing in a decent team is definitely enough to make me stay."
Meanwhile, Henrik Ojamaa, who scored the Motherwell equaliser seconds before the interval, insisted it was "brilliant" to be in Europe.
Ojamaa said: "It's good to have that guarantee. I'm just really delighted for the performance and what it meant."
