Reply To: Error Based Learning vs Reinforcement learning

[Chrissy Durrough Lugge]

Variability in movements from trial to trial can be attributed to motor noise and exploration variability. Exploration variability are conscious attempts to modify movements to be more successful. Individuals are generally unaware of their motor noise. Individuals with cerebellar dysfunction have more motor noise than normal controls (due to ataxia/incoordination). Performance tends to decline with increasing motor noise.
