I'm feeling a bit crayoned-out trying to figure this one out. But if I'm reading the Premack principle correctly, the more preferred behavior (trucks) should reinforce the less preferred behavior (blocks). So I'll go with B. Now, where did I put my trusty set of blocks?

I agree, it seems like playing with trucks would serve as a reinforcer for playing with blocks.

I think you're on the right track with that reasoning. Playing with trucks reinforcing playing with blocks makes sense.

Ah, the old Premack principle conundrum. Let's see, if Jeff spends the most time on blocks, then that must be his least preferred activity. So B is the way to go. Piece of cake, just like building a tower with those blocks!

Yeah, that sounds right. Playing with trucks would be a reward for Jeff after spending time with blocks.

I think B makes sense. If Jeff plays with blocks the most, then playing with trucks would serve as a reinforcer for him.

Haha, this question is a real block-buster! I'm gonna go with D - playing with crayons will serve as a reinforcer for playing with trucks. Why? Because who doesn't love a good crayon-drawing session, am I right?

That's a good point, trucks can be really exciting to play with too. Maybe it's a combination of both crayons and trucks that reinforce playing with blocks.

I agree, crayons are definitely a favorite for many kids. But I think playing with trucks could also be a reinforcer for playing with blocks.

Hmm, I'm not too sure about this one. I was thinking C, but now I'm second-guessing myself. Didn't the Premack principle say something about the more preferred behavior reinforcing the less preferred one? Guess I better review my notes.

But playing with trucks is more preferred by Jeff, so it would serve as a reinforcer for playing with blocks.

I think the answer is B. Playing with trucks will serve as a reinforcer for playing with blocks. The Premack principle states that a more preferred behavior can be used to reinforce a less preferred behavior, and since Jeff spends the most time playing with blocks, that must be his least preferred activity.
