Designing compositional tasks (how they test the idea)

54:34>> That's going to be the shape axis. >> Mhm. >> And then there's going to be another task which is color. And they're going to do the opposite direction which is upper right, lower left. Okay, that's key. So we we need to understand that. And task design is everything. Okay. In a lot of these systems, neuroscience, behavior and abstraction experiments, I remember when I was in my PhD, like we used to spend entire lab meetings just discussing the task >> because the task design actually lets us figure out >> how to probe these very weird questions that we're asking, right? >> Cuz once we have the task, then we can figure out how to analyze what the neuron was doing in this task versus

55:15this task and so on and so forth, right? So the task is as follows. There's a shape axis which is let's say this way. >> And then there's a color axis which is this way. >> Okay. [clears throat] And then what they have to do is they have to switch the axes. >> Okay. So before the shape axis was upper left, lower right. The color axis was upper right lower left. And then now what they have to do is they have to say actually >> I'm going to respond to color but using the shape axis. Okay. Wait. Uh, okay. >> Okay. >> So, >> let's go through this again. >> Okay. >> Okay. >> Yeah. Yeah. Yeah. >> With shape, >> if I see the shape one way, I'm going to go to the lower right or the upper

55:56right. >> Mhm. >> If I see the color, I'm going to go to the upper left or lower left. >> But now in the third task, I'm mixing the two. >> Mhm. >> Okay. So, I I I'm looking at color, but I'm actually responding with the motion of the shape. >> Okay. >> Okay. Yes. >> Here's the here's the key hypothesis.
