New preprint with Sebastian Schneegans and
@bayslab.org
doi.org/10.31234/osf...
Here, we ask whether the key limits of working memory - load and retention interval - are independent, or do they interact? Despite years of research, this question is still much debated.

New work on sensory prediction resolves some long-standing puzzles about attenuation of self-touch
journals.physiology.org/doi/full/10....
loading . . .
Divisive attenuation based on noisy sensorimotor predictions accounts for excess variability in self-touch | Journal of Neurophysiology | American Physiological Society
When one part of the body exerts force on another part, the resulting tactile sensation is perceived as weaker than when the same force is applied by an external agent. This phenomenon has been studie...

Now out in Comms Psych: the "anti-Bayesian" size-weight illusion is a consequence of the brain focusing resources on encoding typical combinations of size and weight (i.e. "efficient coding"). Explains the material-weight illusion too

Weight illusions reflect the efficient coding of everyday experiences with objects. Bayesian models that account for the resulting differences in discriminability predict the size-weight and material-...

New with @robthedatafiend in Psych Review: for every visual feature dimension there is a consistent upper bound on the "s.d." you can obtain by fitting errors with a normal+uniform mixture...and it just might be telling us something about neural tuning!
