Accuracy of delayed non-matching-to-position performance as a function of behaviour during the delay period. Panels show percentage of trials (mean ± SEM) with a correct outcome as a function of trial type (appropriate only, none, both and inappropriate only) after treatment with (A) 10 mg·kg−1 caffeine in the first and second exposures, (B) combination of 0 or 1 mg·kg−1 THC with 0 or 10 mg·kg−1 caffeine or (C) combination of 0 or 1 mg·kg−1 THC with 0 or 10 mg·kg−1 CPT. **P < 0.05, significantly different from appropriate-only trials under vehicle conditions. Bars that extend above the grey band are significantly different (P < 0.05) from chance (50%).
