Distill (April 2, 2019)
A very good blog-style post on gaussian processes. It’s easy to read and has some nice interactive figures.
Here we list new papers by members of the sensoriomotor superlab:
Sequence learning is driven by improvements in motor planning
Ariani, G., and Diedrichsen, J.
In two behavioral experiments, we used a sequence production task to uncover elementary components of skilled motor performance. We show that performance improvements are not fully explained by faster single-item selection, nor improved motor execution. Instead, much of the learning can be attributed to an enhanced ability to plan multiple sequence elements into the future.
The effect of response complexity on simple reaction time occurs even with a highly predictable imperative stimulus
Maslovat, D., Klapp, S.T., Forgaard, C.J., Chua, R., and Franks, I.M.
Neurosci. Lett. 704, 62–66 (2019)

Please keep in mind that the appearance of a paper on our reading list should not necessarily be considered an endorsement of the work unless of course we explicitly endorse it, for example in a blurb. These are just papers that have caught our attention this week. As always, please read papers with a critical eye.
