Empirical research shows that deficits in executive/monitoring abilities (inhibition, error detection, problem solving) following acquired brain injury produce serious impact on patient's daily life performance. The authors developed an intervention method aimed at improving "on-line" error detection and correction abilities during performance of naturalistic action. Patients will be asked to complete two significant everyday activities (e.g. making a sandwich and setting the kitchen table for four people) while increasing the level of monitoring requirements as their performance improve. Monitoring requirements increased by presenting new semantically and physically related distractors and increasing the number of conflicting/problem solving situations. The treatment involves a metacognitive contextual intervention program based on providing systematic online/offline-feedback on their own performance, with emphasis on making the patient aware of how to deal with distracting/conflicting situations that were previously failed. The authors predict that errors committed and addressed through the feedback sessions (errors, actions towards distractors, failures to detect/solve conflicting situations) will be reduced on post-intervention performance compared to baseline. The authors also expect behavioral improvements to generalize to trained tasks but adding new distractors/conflicting situations or even to untrained tasks.
