 Both Castles and Coltheart have also criticised the Arrowsmith Program and other "brain training" programs such the Dore Programme and Brain Gym as based on an oversimplification of neuroplasticity and other neuroscientific concepts.According to a January 2015 announcement from the Archdiocese of Sydney, the two-year school trial in Sydney had "outstanding results".The Arrowsmith Program was incorporated into the Sydney Catholic School system in 2015 and expanded to include both primary and secondary school students.
