Someone commented same thing but want to restate, thank you so much for teaching me without making me feel stupid. I paid good money for instructors to try to do this but all they did was yell at people who didn’t understand. “It’s such an easy concept what don’t you understand guys?!!?” I swear I have ptsd from this class 😂😂 but lovely great video, to the point and nice instructor teaching on the screen.

Hey, how to calculate my stability envelope if my mean is small (2.1) what would the envelope be?

Can you please explain the variation non-concurrent baseline design? I am not understanding how it could be possible to "apply treatment to several individuals at delayed intervals."

I had an exam question that showed dashed lines under the data points instead of solid ones. What is the difference and does it mean prediction when its dashed?

Why time lag on the baselines for the second and third participant? Is it just to reach steady state? Whats the purpose of it?

Thank you!!!

Thank you for this great video. Is it possible that high variability will affect the accuracy of the line? I ask because I created mock data in google sheets and compared my results using this method and the trend line google sheets generates. I got a negative trend line when just doing visual analysis, but google sheets said it was trending positively. I checked it many times to make sure that I hadn't errored in the process. Any thoughts or suggestions?

This was very helpful! I often here Withdrawal and Reversal designs used interchangeably. When taking a mock exam, I got a "reversal" question incorrect because there was no return to conditions without interventions in the example which essentially would have been more so withdrawal if it did. This helped me understand the difference ! Thank you :-)

You're F Great!!!

Thank you so much! This video was sooo helpful to me!

Classical conditioning and operant conditioning were one of the first concepts I ever learned in psychology. I’m currently taking a Behavioral Analysis course during my last semester of my undergrad and the first things mentioned aside from learning, behavior, neuroplasticity, and experimental behavioral analysis, is Respondent Conditioning. I was struggling to understand the textbook due to its use of abbreviated language of unconditioned, conditioned responses and stimuli, but this video helped me build a more concrete foundations to its meaning and its difference from Operant Conditioning. Thank you!

You taught me more about this than the people who were supposed to be helping me learn this. And you did it in a way without making me feel like an idiot for getting multiple probe confused!!! Thank you SO much!!!

Thank you this has been very helpful! Have a blessed New Year.

That looks fun

Thanks.. It was very helpful.

Amazing, keep up the good work! I’d recommend checking out promosm!!! ! It will help you grow your channel.

Thank you, very helpful for me!

Thank you!!

Back in '87 we stayed there several times.. The Arizona D.E.A. had the room next door.. By chance hardly!! LOL

Thank you for sharing this! It was so helpful!

Hello, Dr. Carl Liapson. My name is Roberta. I am a graduate student at St. Cloud State University, and I while digging for videos on single subject designs I came across yours! They have been really helpful , so thank you for doing this. On a side note, I ran into a doubt while reading one of your suggested articles for reversal/withdrawal dessign (Carrigan et el., 1995). They say they use a reversal design, but I was so in doubt. I think this is more like multiple baseline, maybe? They aren't changing the contingencies, just using the same contingency in different locations. The behavior is taking condoms out of the dispenser, and the reinforcers are the condoms. The behavior that is reinforced never changes, and there are no alternative behaviors. I understood they said it was reversal because they reversed the locations (A then B, then go back to A, then back to B). So, I actually am trying to figure out why this article could be considered a reversal or withdrawal and I would appreciate it if you could drop me a line here. Thank you so much!

Hello Dr. Liapson, I'm beginning my dissertation at TAMU - Commerce, TExas. I'm using SCRD and your videos on visual trend analysis are so helpful to me. I'm lost on how you are finding the middle of the two halves during split middle analysis. DO you have a video on that?

This teacher sucks. There is no reason to pick at the kid reapetedly. If the student refuses to work but is willing to sit there, then fine. Let them sit there for awhile. The fact that he forced a confrontation, plus grab the kids arm is very unprofessional. Never touch a student. Especially and angry student.

thank you very good video. the best so far!

So you know how the Weebly homepage has those block and or squares overlaping two pages do you have any idea how to do that?

This is so helpful - do you happen to have any info on how to calculate improvement rate difference? I can't quite seem to grasp it!!

Hi, is the method of calculating non-overlapping data the same for using the PAND? Thank you.

There are so many things bad about what this teacher did I wouldnt even know where to start - he has an arrogant tone and basically throws gas and wood onto the fire and lights the match. This is a terrible situation. Bad teaching period.

Hello i need help to write ch4 and 5

very useful! thank you so much!

Screen is very blurred. Makes this extremely difficult to follow along.

Well done video, and wanted to use it as a resource for my own students, but the quality is rather poor when you make it full size... any chance you have a better version?

Thanks to you video I was able to fix my swamp cooler! I rent and they sent out some guy who looked like a cave man and he did a lousy job. The pipe they used to connect the pump to the "spider" was too short, so the pump was too high to pump the water needed, and the spider was so clogged that only a trickle came out.

Gosh Heidi; there are programs in almost every school district in the city. This competition was just the Tucson region; there are lots of teams. Some are also run by Girl and Boy Scouting Groups

We are moving to Tucson this summer from St. Louis area. My daughter has been doing robotics the last two years. I have been having a hard time finding it out there... can you tell me what schools have it or did you put a team together yourself? Thanks!

cool, looks like fun! :-D

Well, you're welcome. Just made the video to show my brother about the wacky roof systems we have out west. Glad it helped you.
