Although the interpretation of these results was subsequently challenged, more recent research has confirmed both tha t facilitation of reasoning with abstract deontic rules is a robust phenomenon, and tha t PRS theory provides the most complete account of the factors tha t determine when such facilitation is obtained. In particular, a violation-checking context provides a major cue to interpret the stated rule as a regulation, and explicit negatives describing cases facilitate matching
