⚖️ Decision Making

The drift-diffusion model explains perceptual decisions as noisy evidence accumulation toward a threshold. Watch how evidence builds over time until a decision boundary is reached.

Generation: 0
Current Evidence: 0.00
Decision: Undecided
Mean RT: - steps
Drift-Diffusion Model:
• dx = v·dt + σ·dW
• v = drift rate (signal)
• σ = noise (diffusion)
• Speed-accuracy tradeoff
