Scientist investigating how we use our senses to control our movements
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...

The simulated distribution of measured saccades (black) consists of 60% saccades to the target (green), 20% to the distractor (red), and 20% to the global average (blue). The red and green curves have a 7° standard deviation; for the blue curve it is 20% of the target-detractor distance.

In the same paper, I also show that if one applies the most popular method to the average age of a youth soccer team, we get a result (red) that differs from the actual mean (blue):

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...

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?
