Applying a combination of PRT and limited NRT resulted in all macaques being trained to fully cooperate for research procedures within the set time frame, making this training regimen an effective one.This project was supported by NIH/NCRR Grant P51OD011132 to the Yerkes National Primate Research Center, and the following individual NIH/NINDS grants (TW): RO1NS049474, R01NS054976, R01NS042937, R01NS062876, and P50NS071669. Positive-reinforcement training (PRT) is a form of operant conditioning in which the animal receives rewards for desired behavioral responses. Similar gradual processes were taken with the next steps of the pole approaching the collar, the pole touching the collar, the pole attaching to the collar, and the macaque being transferred and secured into the primate chair. Regression should be considered a normal part of the training process, and it will likely vary across individuals, by steps in the training, and in its duration and magnitude. The squeeze mechanism then was moved forward in small increments (that is, 1 in. Animal Control Pole; How It Works; Manufacturers of the World's Finest Animal Control Pole - Since 1952.

Therefore, once the macaques began experiencing that the pole-and-collar restrains their movements, the steps were more difficult and required more training time. Shaping included systematic desensitization and counter conditioning techniques. To monitor training progress, trainers recorded information about each training session including the session duration (in minutes), the highest training step reached for each session (step 1, establishing the bridge; step 2, stays in training position; step 3, tolerates the pole approaching; step 4, tolerates the pole touching a neutral area of the body; step 5, tolerates the pole touching the collar; step 6, tolerates the … Close search. This is important to keep in mind when preparing animals for chair restraint. at a time), with the trainer using the clicker and reinforcing the macaque for continuing to remain calm during each step, until the animal was in the position that the trainer needed to attach the pole, and the squeeze mechanism was released. If animals showed signs of fear or aggression as the pole approached, the trainer slowly backed the pole away until the macaque appeared more comfortable, and then the steps began again. Therefore, 4 wk before the start of experimental procedures that required the monkey to be restrained in the chair for a period of time, the training progress was evaluated jointly by the trainer and the Primate Training Specialist. Regression in performance was common after the initial restraint (that is, 6 monkeys showed regression after the time when the pole was first attached to the collar), and, although temporary, required additional time to work through. The amount of training time spent with each macaque was dependent on the animal's response to each step in the training. Prior to the start of beginning training, animals were sedated (ketamine, 5 to 10 mg/kg) and a plastic collar was loosely fitted around the monkey's neck, to which a metal capture pole could be attached during future training. The chair used in this assessment was custom built, with an open-air design that allowed access to all parts of the monkey's body, similar to the commercial chair available through Primate ProductsBecause the data were not normally distributed, a nonparametric Mann–Whitney test was conducted (SPSS Statistics v17, IBM, Armonk, NY) in an effort to determine any sex-associated differences in the total number of training sessions needed to complete the goal behavior, the total number of training sessions that included the use of the squeeze mechanism, and the percentage of training sessions for each step of the training process.NA, the training step was not used (that is, the macaque did not need to acquire that behavior to progress in training; the behavior was train in conjunction with the following step; or the behavior was incorporated during an earlier step).Training terminology modeled after that in references 11 and 25.
