I think almost all scientific projects should be planned carefully. And I think an app can dramatically improve that. So I wrote an app for that (free for now, if you can fund this let me know). I tested it quite a bit (>8000 users in beta so far). try it: planyourscience.com

A new, Short and Sweet open-access paper on how briefly hiding the hand impedes goal-directed arm movements. Briefly is really brief: we find a decrease in performance in goal-directed movements due to just a few ms without vision of the hand (target remains visible). doi.org/10.1177/0301...

Following a discussion with Mindy Levin about the limitations of using VR in motor control and rehabilitation, I joined her in writing this review.

OK so totally crazy thought but hear me out how about we stop paying so much money to Elsevier and Wiley and Springer and other publishers and like use that money to finance universities so we don't shut down programs in the Netherlands right now ..

When trying to learn from reward, you explore after non-rewarded trials. One generally assumes that this exploration is random. In our new paper, in contrast, we find that participants repeat changes in the same direction more than random exploration predicts. doi.org/10.1007/s002...

Humans can learn various motor tasks based on binary reward feedback on whether a movement attempt was successful or not. Such ‘reward-based motor learning’ relies on exploiting successful motor comma...

In a recent paper, it was argued that the tendency to direct saccades between target and distractor depends on their distance. In a letter to the editor, we argue that their data can be easily explained by assuming that 20% of the saccades is directed at that global location. doi.org/10.1016/j.vi...

In this new paper by Eleonora Assarioti, we found that in perceptual discrimination tasks, participants tend to choose the option with the lowest explicit motor costs. This challenges the view that the motor system merely executes decisions. dx.doi.org/10.1111/ejn....

Reaching Distance Influences Perceptual Decisions
Participants performed two perceptual discrimination tasks in which we manipulated the motor costs of the two response options by varying the distance to the response buttons. We found a bias towards...

Many authors and textbooks assume that sensory recalibration involves adjusting some consistent internal representation, map, or body schema. In an elegant study, Fuchs & Heed provide new evidence that this is not the case: tactile recalibration is task-specific. doi.org/10.1111/ejn....

When I was on Twitter, I asked how scientists determine the age of their human participants. As about two-thirds of the respondents (and 2/3 of authors) ask for rounded-down age, the average ages reported in the literature may be biased by half a year. Open access at doi.org/10.1016/j.ac...

Scientists have a peculiar way to report the average age of their human participants. They suggest they know this average with a few days precision, but introduce a half year bias. Read about it in my short paper doi.org/10.1016/j.ac...

This is an elegant experiment using a new task (grasping thin objects using a precision grip) to find out how grasping is controlled. The answer: "the digits-in-space hypothesis provides the most plausible account of the data". Worth reading!

We cannot deal with accelerations when intercepting a target. A wheel's valve moves in a way that involves continuously varying accelerations. In a new paper, we show that -in contrast to popular belief- viewing the context of the wheel helps to intercept such a target. doi.org/10.1167/jov....

Spatial contextual cues that help predict how a target will accelerate can be used to guide interc...

Are there people on Bluesky who are brand new to science? Great! Let’s go through a paper-reading tip I wish I knew when I started grad school: Lots of journal articles have additional secret abstracts! Since repetition is key to learning, I often read all 4 when digging into a paper.

The figure shows results of an experiment. Participants behave on average (the planned analysis) the same in three conditions, but I would conclude from the data that they behave only the same in B and C, but that their behaviour is different in A. How would you call (and analyse) this phenomenon?
