 Alright let's look at generalization. First off we got a few airports and these are some of the airports that I've been at around the world and what you'll notice is that they're all the same they're all airports right so you got Kigali in Rwanda which is always empty but it's a beautiful airport and then Legos and when I was there this sign you know the the welcome to Legos sign was a little different when I was there it just said you are in Legos anyway the other one is Dubai which is just gorgeous and then you got Kabul which has changed that's the old airport they've got a new one now but that's the old one. The point is is that we got stimulus generalization here these are all different stimuli Kigali Legos Dubai Kabul they're all different stimuli they're completely different airports they don't know what anywhere like you know they have some similar similar things about them but there and nothing about them is really a lie other than the fact they're airports but your behavior in airports alright is roughly the same you check in you check your bags you go through security you wait for your flight you board your flight when you're called it's all about the same there's some minor differences in there about how they call the flight and if there's signs on the wall or if you're waiting for somebody to stand up with a megaphone and yell at you or whatever it may be or how many you know dollars you have to pay off to the person to make sure your bags get on the airplane or whatever it may be but the idea is that the general behavior the behavior of what to do in an airport is the same basically what we're saying is that the stimulus has generalized you do you have different stimuli but your response is the same so let's think about it in this way I was in Kigali I think it was in Kigali before I was in Legos yeah so I was in Kigali before I was in Legos in fact I have those all in order I didn't realize that anyway so I was in Kigali before I was in Legos and the idea is that I got reinforced for a particular behavior in Kigali and how to behave in airports and now I've granted I already been I've been in airports my whole life so the example is kind of contrived but you'll get the idea so I learned what to do in Kigali and I got reinforced for behaving in a particular way in Kigali so then when I show up in Legos I try the same thing all right so behavior becomes more likely in a new situation as a result of being reinforced in another one so I was reinforced for a particular response in Kigali I get to Legos try the same thing and it works all right get to Dubai try the same thing and it also works get to Kabul and try the same thing and it also works in other words I'm talking about checking in okay so just going to the counter and checking in now there are things that didn't work all right you know how you board an aircraft in Legos is dramatically different than now you board an aircraft in in Dubai right it's just a it's a different process and by that I don't want to get too detailed into it but the basic idea is is that you fight to get on the airplane in Legos but in Dubai it's more like boarding an airplane here where it's nice and orderly fashion and you just kind of walk through and you're all standing in line and all that stuff that's not the case in Legos and Legos it's a race to get on the airplane Dubai you know who knows why but that's just that's just what's developed over the years so there's some stimulus control going on there in terms of learning how to behave specifically in each one but some behaviors are the exact same in any airport no matter where you are similarity is a part of it right and if the stimuli are similar similar of course airports are generally similar in some way shape or form but they don't have to be you know I mean the the Kabul airport is not nearly as nice as any of these other airports that are on here at least the old terminal was the new terminal or was the new terminals pretty good but but there's quite a bit that's different as well so in terms of things that aren't similar you still know how to behave right so if you think about all the details of the airports you know Dubai is all shiny and there's gold and there's but you know stain polished stainless steel and in Legos it's just more like a typical airport in Spokane Kigali was actually a beautiful airport but it was empty it was hardly anybody there right Kabul is dirty and run down and was being repaired all the time and it was just it was just not a nice airport so you've got these different classes of things right so classes are what we think about when we think about concepts and I don't mean classes like CBB 324 321 or whatever I mean like classes of things like horses that's a class of stimuli dogs are another class of stimuli people are another class of stimuli airports are class of stimuli airplanes are class of stimuli there's a lot of differences within each class but the class is the same thing when you see a dog you say dog you don't say oh look a cat right he's not very often the idea there is that you respond similarly to classes of behavior and once you respond similar or sorry respond similarly to classes of stimuli behavior classes are a different thing we'll talk about later so when you have a class basically when you're responding to a set of stimuli as a class then what we say is you have conceptual behavior you're behaving as if you understand that concept right of airports so in order to do that you need to know what makes up a concept and what doesn't so what are the things that go into the class and what are the things that don't fit in the class so big large buildings maybe airports right or they may be convention centers or something to that effect so big large building isn't isn't the criteria that you use to put a building in the class of airport or in the building in the class of convention center and it could be any number of things maybe it's gates or terminals or something like that that you use to identify that that building is actually an airport and you get the class of airports or even better you use the word airport since most buildings since most airports have the word airport on them so that that makes it even a little bit easier so what we have in class forming right are in our concept formation are two things number one discrimination and number two generalization right so you discriminate within class or I'm sorry you generalize within classes right or within concepts so all those think about all the differences that exist in terms of different types of horses right lots of different way horses look so lots of different ways that dogs look but you still know that a dog is a dog I don't care if it's a little Chihuahua or if it's a new family right you still understand that they're all dogs you're generalizing within your class there right you're generalizing within that concept because you know Chihuahua doesn't really look anything like a like a new family but you still say dog in response to seeing either one of those things so that's the generalization the discrimination is between classes or between groups right not within and you learn what is a dog but what isn't a horse so you know the shape of the face the shape of the tail the shape of the hook you know you got the hooves versus the paws you know that type of stuff so you're discriminating between classes but the idea there again is that you do need both discrimination and generalization in order to do conceptual behavior so you need to learn what is a class and what isn't a class and how does that what is it related to some other class
