Schemas (or schemata) develop through two processes: (a) Assimilation (from biology) means “to take in”, e.g. the early “Grasping Schema” enables the baby to grab and pick up small convenient objects. (b) Accommodation (also from biology) means “to change”, e.g. the “Grasping Schema” develops by altering to cater for objects different in size, shape and weight.
