I'm starting this thread as a carry over from the member introduction forum. The thread moved into more of a reward marker discussion, an interesting topic. What is a reward marker? Is it the same in theory as a NRM (eh eh, try again) or is it something different? A reward marker simply signals to the animal that it will be reinforced when they hear the sound of the marker. The difference between a reward marker and "good boy/whale/chicken/dog" is that the reinforcer MUST follow or the reward marker is diluted in it's meaning. Many trainers absolutely use a marker to say "good job" but do not call them what they are not.....reward markers. If the sound is not followed by a reinforcer than it is not correct to call it a reward marker but rather praise or a bridge to nowhere..
