New commentary: The power and potential of a blink

Martin and Carolin just published a commentary in PNAS about the potential of thinking about blinks as more than just the gates of perception -- they may also play a critical role in changing some of the earliest computations that are performed by the visual system. Read the commentary here: https://www.pnas.org/doi/10.1073/pnas.2404021121 And we also recommend … Continue reading New commentary: The power and potential of a blink

New papers exploring eye movements and psychosis

We've been pushing forward several papers in collaboration with Katy Thakkar's lab at Michigan State University, dealing with the role of eye movements in individuals with psychosis (and schizophrenia)! Here's one on an oculomotor measure of psychosis: https://academic.oup.com/schizophreniabulletin/advance-article/doi/10.1093/schbul/sbad180/7584025. But interestingly, it isn't always that individuals with schizophrenia must necessarily be worse off. Here's another paper … Continue reading New papers exploring eye movements and psychosis

New publication: Attention can be oriented across binocular disparities

PNAS nexus has published this paper by Baptiste Caziot, Martin, and Benjamin Backus, where we mapped the 3D shape of attentional focus on stimuli that were individually offset in both eyes to study binocular disparity.Caziot, B., Rolfs, M., & Backus, B. (2023). Orienting attention across binocular disparity. PNAS nexus, 2(10), pgad314. [link] [pdf] Abstract:The spatial … Continue reading New publication: Attention can be oriented across binocular disparities

New publication: An interactive motion perception tool for kindergarteners (and vision scientists)

Aravind Battaje, Oliver Brock, and Martin have just published a short and sweet paper in I-Perception titled “An interactive motion perception tool for kindergarteners (and vision scientists)”. Abstract: We implement Adelson and Bergen's spatiotemporal energy model with extension to three-dimensional (x-y-t) in an interactive tool. It helps gain an easy understanding of early (first-order) visual motion perception. … Continue reading New publication: An interactive motion perception tool for kindergarteners (and vision scientists)

New preprint on saccade-induced smear released

Richard, Mara and Martin as well as Thomas Seel and Jörg Raisch are proud to present this new article on bioRxiv, shining light on saccadic omission. On that occasion, congratulations to Mara on her first publication! You can find an interesting thread contextualizing the findings on Martin's twitter.Schweitzer, R., Doering, M., Seel, T., Raisch, J., … Continue reading New preprint on saccade-induced smear released

Martin back from Sabbatical at Dartmouth College

Martin spent a sabbatical at Dartmouth College, from August 29th to December 31st, 2022. As a Fellow of the Harris Program, he enjoyed numerous scientific interactions with Peter Tse, Viola Stoermer, Patrick Cavanagh, Caroline Robertson, Tor Wager, Matt van der Meer, and their groups at the Department of Psychological and Brain Sciences. During his time … Continue reading Martin back from Sabbatical at Dartmouth College

In press: Oculomotor freezing indicates conscious detection free of decision bias

The same visual stimulus can sometimes reach awareness, while other times it does not. To understand why, we need objective, bias-free measures of awareness. We had previously discovered that a reflexive freezing of small eye movements indicates when an observer detects a stimulus (see White & Rolfs, 2016). In a new set of experiments that … Continue reading In press: Oculomotor freezing indicates conscious detection free of decision bias
