Flexible tapping synchronization in macaques: dynamic switching of timing strategies within rhythmic sequences

We trained macaques in a visual synchronization tapping task and using an inference model, we found that they are highly precise and accurate in their rhythmic performance. The model also captured a dynamic switch in behavior. At the beginning of the task, the monkeys used their prior knowledge about the interval statistics and then switched to an error correction mechanism to generate intervals depending on the previously produced duration.
