If you're at @VSSMtg and curious abt the follow-up to our recently published paper (👇), come find me at my poster "Feeling of agency in visual actions? No evidence for effect binding in microsaccades" tomorrow!
📍 Poster 53.405, Pavilion
🗓️ May 20, 2025 | 8:30 am – 12:30 pm
1/n Very happy to share that our new paper was just published in @CognitionJourn:
“Sensorimotor awareness requires intention: Evidence from minuscule eye movements.”

9/n Bottom line: Intention acts as a gate to sensorimotor awareness. Even at the scale of microsaccades, simply intending to move (or to hold still) boosts our ability to notice the action—while visual consequences alone don’t help.

8/n Awareness of the eye movement itself, however, was low for spontaneous microsaccades but higher when a movement was intended or occurred despite attempts to fixate.

7/n We found that visual sensitivity was high whenever a microsaccade (real or replayed) slowed the stimulus on the retina—regardless of whether the action was intended, unintended, or spontaneous.

6/n After each trial, participants reported whether they saw the stimulus, whether they thought they made a microsaccade, and how confident they were that their eye movement caused what they saw.

5/n To tease apart motor commands from visual feedback, we used a rapidly phase-shifting stimulus that’s invisible during steady gaze but pops into view when retinal motion slows—either due to a real microsaccade or a replay of its retinal trace. No-stim trials acted as controls.

4/n Our approach involved directly comparing three types of microsaccades:
• Intended (consciously planned)
• Unintended (executed despite intention to fixate)
• Spontaneous (uncontrolled or automatic)

3/n We developed a novel paradigm that allowed us to dissociate the role of action intention and sensory consequences for awareness.

2/n @svenohl, @MartinRolfs, and I investigated how intention modulates awareness of one of the smallest human actions: microsaccades—tiny eye movements typically generated spontaneously during fixation.

I won a prize for my poster at this year's ECVP! :) If you want to check it out, you can find it on my ResearchGate profile: researchgate.net/publication…
If you are interested in microsaccades and eye movement awareness, come see me at my poster @VSSMtg today :D
@JanKlanke will present his poster on “Different levels of awareness for spontaneous, involuntary, and voluntary microsaccades” (#63.426) at Pavilion on Wednesday, May 24, from 8:30 am to 12:30 pm.

Who's at the #DGPs2022 this week? 👀Today at 14:00, @JanKlanke will give a talk on "Effect binding for undetected spontaneous micromovements" in the "Action and time perception" session. Looking forward to meeting you at the talk! #dgpskongress

We would like to offer a couple of paid internships to refugees from Ukraine. Students enrolled in a Ukrainian university who would like to help us with data collection/with an interest in vision science, reach us here: rolfslab.org/2022/03/11/ukr-… #AcademicTwitter #ScienceForUkraine
