Implicit and Statistical Learning

Scope: Acquisition of structure without explicit instruction: implicit memory, procedural memory. Paradigm-level coverage includes artificial grammar learning, serial reaction time, statistical word-segmentation, perceptual category learning — these live in task_details.json, not as separate process rows.

Out of scope: Reinforcement-driven associative learning (Associative Learning and Reinforcement).

This category contains 2 processes.
