If reinforcing behavior is the most
important thing you can do when training a dog, then marking that
behavior probably is the second most important. But then, the
trainer’s ability to see behavior is also important. Honestly, it
almost feels like a chicken-and-egg argument; you could make an
argument that they are equally important.
Kathy thinks that teaching people how
to mark behavior takes precedence over sharpening their observational
skills. Of course, marking behavior does require seeing it, but she
likes to backchain when training humans as well as animals, so let’s
talk about marking first.
Kathy works with a small group on their skills! |
Marking is important, Kathy told us,
because figuring out which behaviors are correct is harder for the
animal if the reward is functioning as both information and the
reinforcer. It’s just not as clear. And of course, a marker like a
clicker has a number of other benefits. Kathy identified four: the
clicker acts as information (yes! That is the behavior I want!), a
secondary reinforcer (which strengthens the behavior), a bridge
(making a promise that reinforcement is coming), and also as a cue
(to eat).
Good markers are SURE:
Short, preferably only a
fraction of a second.
Unique and unlike any other
signal the animal will recognize.
Reliable or consistent across
trainers, contexts, and times, and
Evident and easily distinguished
from other stimuli.
Once you have an effective marker, you
need to protect it. Markers become weak when they don’t provide
information, have become poisoned or infected by use during anxious
situations more often than calm ones, or don’t actually mark
anything. They can also become weak if the trainer requires the dog
to do more behavior after the marker has been given.
But marking a behavior is only
worthwhile when the timing is good, which requires us to clearly see
what it is we are marking. Good timing is essential because otherwise
you run the risk of inadvertently mark and reward the wrong thing!
It’s also challenging to have good timing because there is an
inevitable time lag between seeing the behavior and the physical
action of clicking. Assuming absolutely no cognitive
processing time, the nerve impulses needed to travel from the eye to
the brain and then the brain to the fingers is about 125
milliseconds. It may not sound like much, but remember that you will
need time to think and then your animal will need time to process the
sound.
Which means that good timing requires
you to be able to see a behavior before it happens; you’re clicking
the earliest precursor to the behavior. You also need to pay
attention, which is, let’s face it, harder than it sounds. You need
to be very clear about what you’re looking for and give your full
brain power to the act of seeing even the tiniest of changes.
You’ll need to get past your judgment
and analysis, past talking and prompting, past labels and
preconceptions, and past the audience effect (people watching you) if
you are to see clearly. Really, seeing requires you to be fully,
completely present, something that is far more difficult to do than
it sounds.
See- Mark- Reward. All important, all
dependent on one another. And all skills that you can not only learn
but also improve. So, what do you do to improve your ability to train
effectively?
