James, 22, won the women's sprint and keirin at last year's event in Belarus, and also picked up bronze medals in the 500m time trial and team sprint.
This year's event starts on Wednesday, and James said: "I'm trying to go with the same mindset I had last year.
"Just go in with a completely open mind and not expect anything from myself."
The Welsh cyclist added: "I've worked really hard with Dave Readle, my psychologist.
"Hopefully I can have the same mindset again. I was so relaxed and I enjoyed it. I think that's when I race my best. When I'm enjoying it and I'm most chilled out."
Britain won five gold medals at last year's Worlds, with Jason Kenny winning the men's keirin and Simon Yates the points race, while Laura Trott, Dani King and Elinor Barker won the team pursuit.
Archibald staked her claim for a place in the team by winning European gold on her British debut with Trott, King and Barker in 2013, with the quartet lowering the world record on two occasions.Trott, King and Barker are joined by Joanna Rowsell and Katie Archibald in a five-strong squad for the new four-rider 4km team pursuit, which is making its World Championships debut.
However, in December, Trott was missing as Rowsell, Archibald, Barker and King set a new world best of four minutes, 16.552 seconds at a World Cup meeting.
Archibald, 19, told the British Cycling website: "I really want to be riding in that team pursuit and trying to make sure we get a medal.
"It's mad that it's a realistic prospect now because half a year ago, I was scratching at the door trying to get a qualifying time for the Commonwealth Games thinking that was a massive dream and now to be riding for GB, it's amazing."
The British women have won team pursuit gold in six of the seven world championships since its inclusion in 2007 - taking silver in 2010.
A youthful men's team pursuit squad will be led by Ed Clancy, who has won three gold medals and two silvers since 2007.
The 28-year-old is joined by four other endurance riders in the 17-strong British team - Steven Burke, Sam Harrison, Owain Doull and Jon Dibben.
Burke, 25, and 21-year-old Harrison rode in last year's silver medal-winning quartet, while 20-year-olds Doull and Dibben made their World Championships debuts in Minsk last year.
"The team's gelling pretty well this time," said Clancy. "We've spent plenty of time together so it's good to get to know them because I didn't know Owain and Jon so well before this winter.
"It's been nice to spend a bit more time around them. We feel like a proper unit this time."
Clancy will also ride in the two-day six-race omnium - an event he won in 2010 - although he says the priority is the pursuit.
"The team pursuit training takes up 85% of your time," he explained. "We've done little bits of specific omnium training.
"The thing with pursuit is it's a more dependable medal so it makes sense that we put the majority of our effort into that one."
