Two-Factor Theory of Emotion Lab (2D)

This simulator brings Schachter and Singer's classic two-factor theory of emotion into an interactive 2D circumplex view. Push a physiological arousal "injection", let a leaky-integrator model of adrenaline rise and decay toward it, then pick a situational appraisal — the cue your mind reaches for to explain that arousal. Toggle whether the subject is informed about the injection's real cause to see misattribution strengthen or fade, and watch the resulting felt emotion land live on Russell's valence-arousal circumplex, with heart-rate and valence readouts updating continuously. Drag the plane to pan and scroll to zoom, just like panning a real spatial view.
