Document Summary
Coordinate several schemes to produce one certain result. Begins in substage 4 8-12 months but fully achieved in substage 6, 18-24 months. The ability to perform an action seen earlier. An internal image of a past event or object. What are encoding, storage, and retrieval? information processing theory. Infants encode initial information, store it for future use and can recover it later. Lack of memory for events that occurred prior to 3 y. o. Interference: more episodic memories created-harder it is for brain to locate a specific one. Language: limited by vocab at time of memory, can only describe events using words known at that time. Categorical filter-we cannot easily encode it, no mental representations. Contrary findings: other animals who cannot speak also exhibit infantile amnesia. Hippocampal neurogenesis: hippocampus encodes and retrieves episodic memories. Rapid production of new neurons causes previous episodic memories to be lost or erased. Explicit memory and brain regions information we consciously choose to retrieve.
