| Macquart et al.((Macquart, D., Latil, G., & Beugnon, G., "Sensorimotor sequence learning in the ant Gigantiops destructor." //Animal Behaviour//, October 2007. doi:10.1016/j.anbehav.2007.10.023 )) use what is called a linear homing maze (shown below) to test whether ants can learn sequences such as LRLRLR or LLRRLL (L = left, R = right). Their homing maze consists of 8 chambers, each with two doors. One of the doors has a transparent plastic covering such that the ants are not able to move through it. Training consists of running individual ants through this maze until they perform the correct pattern at least 75% of the time, i.e., do not mistakenly choose the transparent door option. No rewards or punishments are administered during training. | Macquart et al.((Macquart, D., Latil, G., & Beugnon, G., "Sensorimotor sequence learning in the ant Gigantiops destructor." //Animal Behaviour//, October 2007. doi:10.1016/j.anbehav.2007.10.023 )) use what is called a linear homing maze to test whether ants can learn sequences such as LRLRLR or LLRRLL (L = left, R = right). Their homing maze consists of 8 chambers, each with two doors, which the ants pass through sequentially. In each chamber, one of the doors has a transparent plastic covering such that the ants are not able to move through it.

| Once the ants have learned this, the maze is extended to include two additional chambers in order to test whether ants appear to generalize the pattern. For simple mazes with no alternations, (e.g., LLLLLL) ants make correct choices 95% of the time in the additional chambers. For slightly more complex mazes with one alternation (e.g., LRLRLR) ants make correct choices 72% of the time. For double alternation mazes (e.g., LLRRLL), ants complete the correct pattern only 43% of the time. In all cases, performance in the first additional chamber is significantly higher than performance in the second chamber. | Once the ants have learned this, the maze is extended to include two additional chambers in order to test whether ants appear to generalize the pattern.
