 We're gonna talk about a few things that affect a stimulus control because things do. I don't know. I suppose the first thing that you need to remember is pretty obvious and sometimes I think our field, I don't know, it's both a benefit and it's kind of an annoying thing especially for people that aren't in our field, that we love to talk about all the obvious stuff and we make it a point of turning the obvious stuff into a hard science and that's important for science across the board but I'm just saying because this is one of those things that's so obvious if you can't attend to something folks, you can't develop stimulus, you can't develop stimulus control with you or over you I should say why right because if you can't see green like if you can't identify the color if you don't see the stimulus in your in your environment then I can't teach you what it is right if I tell you to if I'm driving down the street I'm like wave at me and you don't wave at me maybe because you didn't attend to me maybe you didn't see me right so attend pre-attending skills are the things that I'm thinking about here if you if you tell someone or if you teach someone to attend then you've taught a skill that allows them to then develop stimulus control or have stimulus control developed over other things right of the behaviors so the absolute key within each sort of stimulus control is attending right so it's a powerful skill to teach sometimes you have to teach it to adults sometimes you have to teach it to dogs sometimes even kids but it's just a genuinely good tool to use so the other thing that the tool to use alright it's a requirement it's not tool to use so pre-attending skills oh I don't know that stimulus was way more salient than what I was doing with my tie at the time and you're gonna rewind that to find out what I was doing with my tie and you're gonna find out it was nothing so I'll just you're gonna no but now you're gonna double-check me because interobserver agreement right so anyway um so a stimulus that is extremely salient will be the one that sticks out in the environment right so that sort of thing is pretty salient it's you're going to remember that hopefully it'll be one of those things that stuck out in this video so salient stimuli are the ones that are turn to think of a better way to describe this so the stimulus that sticks out the most is the one that's the most salient right so think of it that way right so two more things so those are the ones that you're gonna readily develop stimulus control to in an environment the subtle nuance differences take a while to develop you always tend we always tend to focus on the most salient stimuli first so two more things masking and overshadowing let's talk about overshadowing first because that has to do with the development of stimulus control and learning new relations about stimuli so overshadowing is when we have one stimulus that basically blocks the acquisition of learning or sorry overshadows the acquisition of learning to another stimulus blocking is a whole different thing and we can talk about that at a completely different time and a completely different set of videos because for whatever reason we don't really talk about it in here so anyway I'm so overshadowing we have one stimulus that's gonna overshadow another stimulus so I could have this unbelievably bright right shining upon you and then I could do a really soft sound and I'm supposed to get you to do something to the soft sound but you're not going to respond to the you're gonna be responding to this unbelievably bright light that's just gonna totally overwhelm you so as a result you probably won't learn about that right so that's the idea of overshadowing just one stimulus in the environment it is more salient it totally overwhelms the organism to learning something about another stimulus in that particular environment another one is masking okay this has to do with skills that you've already learned so you already have stimulus control but you may not be able to perform a particular task because of some other stimulus that is in masking the ability of stimulus a right to elicit there or to evoke the response that were that were after not elicit sorry I'd sometimes they get confused in my head they all the damn e words anyway it's because oh I wonder why maybe the video or maybe the video camera is masking my ability to discriminate on elicit evoke and all that in the mid right so so that's an exact kind of a funny example where I just caught onto the fact I was making that mistake and then in this particular environment so maybe the stimuli around me the lights the camera the cameraman and the studio that we're in maybe all that is masking my ability to discriminate well on the e words and behavior analysis so another example of this is sometimes kids get overwhelmed with noises like my kiddo right now is in school and they're doing a lot of construction in the school and he's having a really hard time doing some of the work that he already knows how to do because of boom boom boom boom in the environment constantly all day long right I remember when I was learning to screw a dive this ages ago we had a there's a pile driving going on they were doing some work on a bridge in the river bang bang bang bang I couldn't we were underwater trying to attend to specific things that we knew how to do but I was getting distracted I was like what do I need to do because I kept focusing on bang bang bang in the water and it was really overwhelming so sometimes stimuli will mask the ability of another stimulus to elicit or to evoke a particular response with from stimulus control obviously so I think that's probably good enough for now and I'll talk to you later another time see it or I won't because I'm not sailing to know are you I can't thank you enough for making it to the end of a video no one watches to the end except you and for that I appreciate it thank you very much please like subscribe share even donate maybe anything just
