Key principles | Error-based learning | Errorless learning |
---|---|---|
Training approach and model | Top-down with an internal focus (person learns to monitor and correct their own errors) | Bottom-up with an external focus (therapist monitors and eliminates the person’s errors) |
Target of intervention | Increased awareness of deficits and the capacity to anticipate, self-monitor and self-regulate errors | Error-free performance on successive parts of the task through observing and practicing correct actions |
Mechanisms (function of errors in learning) | A structured opportunity to make and self-identify errors with therapist’s feedback to realize the functional significance of errors, and practice of self-initiated strategies (stop, check and correct) over sessions | The therapist prevents errors during the learning acquisition phase by modeling each step and the person practices only correct responses over sessions to support habit formation |
Training outcomes (pre vs post) | Reduced errors on the training task, generalization of self-regulation skills to untrained tasks (reduced errors and improved broader behavioral competency) and greater awareness of deficits | Reduced errors on the training task, minimal change in awareness, lack of generalization of self-regulation skills to untrained tasks (minimal change in errors and broader behavioral competency) |
