Consolidation theory

CONSOLIDATION THEORY In order for information to be transferred from Short-Term Memory to Long-Term Memory a period of time for consolidation is required to ensure it is permanently stored. Consolidation refers to the physical changes are made to the neurons in the brain when something new is being learned and immediately following learning. These changes form the ‘memory’ of what has been learned. If there is a disruption during the consolidation phase the information may not be embed in Long-Term Memory. Consolidation is a gradual process that takes up to 30 minutes.

Consolidation Theory (cont...) EVIDENCE for the Consolidation Theory: People who have experienced brain trauma reported they could not remember anything that occurred during a period of about 30 minutes prior to the brain injury Animal research shows that rats that were given Electro-Convulsive Shock Therapy after learning to run a maze could only remember what they had learnt if the shocks occurred after 60 minutes of learning the maze. It has also been proposed that after a memory has been activated and retrieved from LTM it needs to be consolidated again in order to be stored back in LTM. This is called Reconsolidation
