I was wondering if there are some words that describe the characteristic of some person that does not keep up with some supposed pace.
For example, in orchestra performance by a team, one performer playing his instrument always lags behind by a certain amount of time.
Another example, unlike other students, a student seldom ask questions in classes. But he asks a lot of questions after classes. The reason is that he needs more time to think in classes than other students, so not able to keep up with the paces of the classes and not to say to ask questions (although I don't think it is a bad thing).
lag, which you used in your first example? – FrustratedWithFormsDesigner Sep 20 '11 at 15:24
