@adredish I am reading the RoboRator paper (really cool experiment!!) and I cannot understand what the “yoked trials” are exactly. Any chance you or any other author could explain with a different wording?

The issue is that we want to see the consequences of being attacked, but we need to control for general changes across a given day (satiation, weariness, etc). So we are basically dividing each session into "early laps" and "late laps".

On an attack day, the clear place to divide is on that first attack of the day. But that is a different lap for each session for each animal.

For non-attack days, we also need a lap to divide the early from late laps. So we took the four attack laps from the attack sessions and used them (in shuffled order) to separate the early and late laps for the non-attack sessions. We call that the "yoked lap".

Hope that makes sense.
