If you're at @vssmtg.bsky.social 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 morning! 📍 Poster 53.405, Pavilion 🗓️ May 20, 2025 | 8:30 am – 12:30 pm

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 Sven Ohl, Martin Rolfs (@rolfslab.bsky.social), and I investigated how intention modulates awareness of one of the smallest human actions: microsaccades—tiny eye movements typically generated spontaneously during fixation.

1/n Very happy to share that our new paper was just published in @cognitionjournal.bsky.social : “Sensorimotor awareness requires intention: Evidence from minuscule eye movements.” Dive into the details here 👉 www.sciencedirect.com/science/arti...

Sensorimotor awareness requires intention: Evidence from minuscule eye movements

Microsaccades are tiny eye movements typically occurring spontaneously and without awareness but can also be intentionally controlled with high precis…
