About three years ago, we have started working on perception during saccadic eye movements — that is, when the eyes are in mid-flight from one point in the scene to the next. Using a quite unique high-speed projection setup that allows us to rapidly (yet smoothly) move stimuli on the screen, we keep finding new … Continue reading In the press: All is not lost
We are excited to announce that our new paper on local changes in orientation tuning before saccades has just appeared in the Journal of Vision. Here is the link. Clara and Sven did worked together extremely well to get this project from conception to publication in less than two years! In this study, we combined … Continue reading New paper on dynamic changes orientation tuning before saccades.
Betty's paper on the continuity of feature-based attention across saccadic eye movements has just been accepted for publication in the Journal of Vision. Congratulations, Betty! A pdf of the preprint is available here. And here is the abstract: Saccadic eye movements do not disrupt the deployment of feature-based attention The tight link of saccades to covert spatial … Continue reading In press: New paper on feature-based attention and saccadic eye movements.
Together with Katy Thakkar (Michigan State University) and Vaibhav Diwadkar (Wayne State University), we just wrote an opinion piece on the role of corollary discharge in psychosis, and how prediction in the oculomotor system may help us understand the complex polygenic disorder schizophrenia. The review is going to be published in one of the next issues of … Continue reading Opinion article on Oculomotor prediction in psychosis in press in TiCS
We were happy to see that Steve Lewandowsky highlighted Betty's recent paper on feature-based attention and visual short-term memory at psychonomic.org! Here is a link to the blog.
Congratulations to Alex White, whose postdoc project just appeared in the Journal of Neurophysiology! The key finding of this paper is that the pattern of miniature eye movements immediately following the appearance of a stimulus—the reflexive inhibition of so-called microsaccades—reveals whether the observer has seen that stimulus or not. To some extent, this subjective perception … Continue reading New paper: Oculomotor inhibition covaries with conscious detection
Carlos, Sven, and Martin just had a new paper accepted in the Journal of Neurophysiology. As the title suggests, we show saccadic adaptation to a systematically varying disturbance. We are particularly happy about this work as it establishes a new paradigm to study plasticity in the saccadic system that—as we argue at length in the paper—allows … Continue reading New paper: Saccadic adaptation to a systematically varying disturbance
Because the eyes move, the correspondence between each location in the world and each location on the retina is arbitrary. From one fixation to the next, each object changes places on the retina. Both psychophysical and neurophysiological studies aim to better understand how we keep track of locations as the eyes move about. Yet the links between neural and behavioral findings remain obscure. Inspired by … Continue reading In press: Spotlight on Remapping attention pointers
Together with Michael Dambacher, Martin has submitted a comment on the recent theoretical paper "Cognition does not affect perception: Evaluating the evidence for ‘top-down’ effects" by Chaz Firestone and Brian Scholl (Yale University). The comment has now been accepted for publication. It will appear along with a number of other comments and a response by the authors in a (hopefully … Continue reading In press: What draws the line between perception and cognition?
Our collaboration with Katy Thakkar and her colleagues at Utrecht University has just assumed tangible shape. Our manuscript "Failure to use corollary discharge to remap visual target locations is associated with psychotic symptom severity in schizophrenia" has been accepted for publication in the Journal of Neurophysiology (which is becoming my favorite journal). In our study, we compared … Continue reading New paper on remapping in schizophrenia
