This study trains gradient boosting (EMBER) and a custom transformer (ORBIT) on Counter-Strike 2 telemetry to predict coarse fight-or-flight reactions, reporting roughly 71-74% accuracy against a 51.5% majority baseline and a modest edge over an LLM baseline. The comparison is not compute-matched, and the neuroscience framing is explicitly hypothesis-generating, so the results support the predictive claims more than the mechanistic ones. For ML readers, the useful takeaways are the leak-reduced feature construction and the caution that per-tick accuracy gains don't establish a cognitive interpretation.
Toward Fast Human Reaction Modeling from High-Frequency Digital Interaction Data
arXiv:2610.35079v1 Announce Type: cross Abstract: We investigate whether limbic-like signatures of rapid, salience-driven behavior can be identified in high-resolution Counter-Strike 2 telemetry. This exploratory study introduces Ego-Knowledge, a leak-reduced reconstruction of each player's plausible perceptual state, supported by a millisecond-precision visibility engine and a reaction-centered extraction pipeline. Using a neuroscience-motivated 60--120 ms window, we derive coarse fight-or-flight labels from visibility- and damage-triggered events, with back-damage cases enabling constrained reaction-time analysis and manual label checks. We train two telemetry-native models using only information available by the trigger: EMBER (gradient boosting) and ORBIT (a custom transformer). On the full validation set, EMBER achieves 73.5% accuracy and ORBIT 71.2%, versus a 51.5% majority-class baseline, and both generalize to held-out players. The strongest LLM baseline achieves 62.7% on 1,000 validation cases; on these same cases, EMBER (73.6%) and ORBIT (70.9%) perform better (McNemar p=1.3e-9 and 1.5e-6, respectively), with orders-of-magnitude lower inference time and cost, though the comparison is not compute-matched. Including a short post-trigger window changes forecasting into early response recognition, raising accuracy monotonically to 85.15%. We propose this curve as a candidate probe of the transition from rapid to deliberative control, but roughly uniform per-tick gains do not establish that interpretation. The neuroscience framing is hypothesis-generating, not mechanistic: physiological ground truth, suitable control distributions, and reverse-inference limitations remain open. We outline extensions to auditory reconstruction, larger datasets, and telemetry-native foundation models.
