Dogs may receive a maximum of one reward every 8 seconds (s). |
Reward trigger rate of at least 8 in 2 of 3 training blocks |
TP2 |
Dogs to move their nose to the target on cue. |
Milk tone played, 10 s window to respond, 20 s Inter-trial Interval (ITI). |
Touches target at least 80% of time after tone for 2 of 3 training blocks |
TP2A |
Reduce reinforcement rate |
Milk tone played, 10 s window to respond, 30 s ITI. |
Touches target at least 80% of time after tone for 2 of 3 training blocks |
TP3 |
