How does Focus Pocus help?

Focus Pocus is powered by the Neurocognitive Training Engine (NCT Engine). The NCT Engine allows delivery of systematic concurrent training in three domains: Working Memory, Impulse Control, and Neurofeedback. The NCT Engine drives beneficial behavioural outcomes by promoting improved ability in these domains, and is supported by published research.  There are specified parameters in regard to:
  • Training frequency
  • Sequencing and proportions of training in each domain within each training session
  • Task types within each domain
  • Brain activity targets and tasks in the Neurofeedback domain
  • Performance-based task difficulty level adjustments
  • Task performance feedback​
