In the 21st century, the physiology underlying identification and the neurological delay is thought to involve autoassociative memory, a neural mechanism crucial to intelligence. Briefly explained, autoassociative memory retrieves previously stored representations that most closely conform to any current incoming pattern (level II in the general semantics diagram) arriving from the senses. According to the memory-prediction model for intelligence, if the stored representations resolve the arriving patterns, this constitutes "understanding", and brain activity shifts from evaluation to triggering motor responses. When the retrieved representations do "not" sufficiently resolve newly arrived patterns, evaluating persists, engaging higher layers of the cortex in an ongoing pursuit of resolution. The additional time required for signals to travel up and down the cortical hierarchy constitutes what general semantics calls a "beneficial neurological delay".
