Two potential rodent models of ADHD were tested for stimulus control differences. SHR/NCrl behavior perseverated toward light-cued levers in Experiment 1. WKY/NCrl behavior did not come under the control of cue lights in Experiment 1. Interval timing was roughly similar for SHR/NCrl, WKY/NCrl, and WI strains in Experiment 2. Latencies to initiate the FI were significantly longer for SHR/NCrl in Experiment 2.
