Neuroscience, can tell us about how people learn and change behaviour. Key elements are:
good mood, good sleep and mild stress, or flow. This should be the principles against which all pogrammes are designed for greater learning and retention.
The science also shows that to change people need to create the insight themselves, no more powerpoints and insturctuiion but powerful questions, reflection and tools that enable people to apply their insight to their job and understand the benifits for them personally.
New behaviour has to be embedded until it is a habit that is carried out even under stress. This calls for shorter chunks of training or development interventions that go on much longer and new behaviours are reinforced through social reward and social pressure.
Measurment of programmes should be whether behaviour changes and business outcomes are met. Not how happy people were the day after the event.
