The lemurs are definitely progressing with the training sessions but now the difference is how advanced they are (when are they ready to do testing) as opposed to whether they are engaging SMARTA. Almost all individuals are engaging SMARTA in various degrees. There are, however, some individuals that want absolutely nothing to do with SMARTA. I might have to take them out from the study.
Also, some of these lemurs are craftier than others; some individuals have figured out to just leave one hand on the target during the whole duration of the training session while having the other hand on the chute eagerly awaiting the dispensing sweet morsel. Ha!
