Iterations - repetitions that are similar, but inevitably slightly different. In a developmental context, these lead to step-by-step improvements, or growth, or re-modelling.

The synaptic re-organisation of the brain as it matures (particularly through adolescence) is largely driven by the iterations and reiterations of neurological actions (signals repeatedly being sent down the same pathways). Likewise, the development of AMBIT's Dynamic, adaptive Manualization, and of a team's knowledge about "how to work best, here, with these young people, in this setting..." is something that develops slowly out of repeated experiences.
