Order effects refer to how the sequence of presenting treatments influences the outcome, meaning the position (first, second, etc.) of the treatment matters, not its repetition or the specifics of the treatment itself. Carryover effects, on the other hand, involve how one treatment might influence responses to subsequent treatments, which is not about their ordinal position but about their interaction over time.
