 Well, Lou who I am not going to attempt his last name or her last name because I don't really know and I'm horrific with last names And first names it's probably not Lou, but I'm going to interpret it as such And if I've done it wrong, please correct me using some tool of correction that heck I don't even care you can pick up the phone and call me and just tell me what your name is and how to pronounce it correctly Because it just I'm bad at it. I'm heck. I don't even oftentimes I forget my children's names So now just call them number one two three and four. So which is easier. Anyway, here nor there So Lou asked about the difference between a DRL and a DRD We could probably just end the video saying there isn't a difference, but that's just not true So at some level there's there's a lot of similarities right differential reinforcement of low rates of behavior DRL a DRD is a Differential reinforcement of a diminishing rate of behavior. Are you satisfied yet me either? Alright, so here we go DRL We got behavior way up here. All right. I I don't know what up here is just bear with me Okay, so DRL behaviors way up here and we're saying we don't want it up there We want it down here. All right, so what I'm going to do in a DRL is differential reinforcement of a low rate So as long as this behavior happens down in this range below here It's going to earn a reinforcer if it happens up here extinction. We're going to ignore it All right, so DRL you have this hard line right here's a line in the sand It's a red line whatever you want to say boom that the behavior happens below it. It earns a reinforcer. It's that simple That's DRL DRD is a differential reinforcement of a diminishing rate. Okay, so as long as The behavior during the period of observation is lower than it was during the previous period You can go ahead and reinforce it So I'm going to set up a very artificial example as a as a visual for you So behaviors back up here this time as long as it's anything below this it's going to get a reinforcer So now all we have to do is make sure it's below this and we get a reinforcer and below this and we get a reinforcer And below this and we get a reinforcer and so on so forth. You're reinforcing that diminishing rate of behavior So they both have the same final effect, which is a lower rate of responding for whatever the response is that you're trying to reduce I just think that DRD fits more along the logical lines of a shaping procedure So you're trying to shape a lower rate of responding So it's easier for the organism the person to achieve this level then easier to achieve this level rather than this gigantic jump I Think if you were to put this with a type of experimental design if you want to link it up with one of those You might think of a changing criterion design. So changing criterion design going to be a little bit more rigid than what a DRD is But they could you be used interchangeably? I suppose you could just set a new criteria each time and as long as you achieve it Reinforcers things are a little different with the changing criterion, but you get the idea I'm just trying to help you draw some more connections. So ask more questions. Thank you very much. I appreciate it That was a video on Behavior analysis if you like it, please share it. Please subscribe. Please donate. We'd like to eat I'm hungry
