WMF-AM: Probing LLM Working Memory via Depth-Parameterized Cumulative State Tracking

Published in arXiv preprint, 2026

We introduce Working Memory Fidelity-Active Manipulation (WMF-AM), a probe of cumulative state tracking that isolates within-pass cumulative load by parameterizing depth K. Testing 20 open-weight models (0.5B–35B) across 13 families, our probe predicts agent performance with r = 0.612 (p < 0.001).

Task-constrained self-initiated attention shifts are indexed by frontal-midline theta ramping

Published in Frontiers in Human Neuroscience, 2025

We investigated the EEG signatures of voluntary, self-initiated attention shifts during visual search. Frontal-midline theta oscillations showed a characteristic ramping pattern prior to attention shifts, reflecting the cognitive demands of self-initiated attentional control.

Commonality of neuronal coherence for motor skill acquisition and interlimb transfer

Published in Scientific Reports, 2025

This study identified common neural coherence patterns underlying both motor skill acquisition and interlimb transfer, suggesting shared neurophysiological mechanisms for these two motor learning processes.

Physics-Aware Video Instance Removal Benchmark

Published in CVPR 2026 Workshop on Video Generation and Beyond Evaluation (VGBE), 2026

We introduce PVIR, a benchmark of 95 videos with a decoupled human evaluation protocol that reveals current video instance removal methods still treat object erasure as 2D texture filling rather than physics-aware scene reconstruction, particularly failing on complex physical side effects like reflections and shadows.
