We were specifically told to not ask questions. Only state observational statements that did not assume what the child was doing/feeling.
While I think that sometimes children will open up when you address them vaguely and give them more opportunity to talk, I also think it doesn't have to that complicated.
Sorry op, we got off topic. I haven't really read a parenting book since ds1 was born. I think many times if your being attentive physically and emotionally and creating a bond, that will help guide you to parent the way your child needs.
