In the context of 'Memory and Forgetting', according to the 'Forgetting Curve' proposed by the German psychologist Hermann Ebbinghaus, why does the most rapid decay or loss of learned material occur in the initial period immediately following the end of the learning process (especially within the first 20 to 60 minutes)?

Explanation

According to Hermann Ebbinghaus's 'Forgetting Curve', a major portion of newly learned information (approximately over 50%) is forgotten within the first hour. The primary psychological reason for this is that newly acquired knowledge requires time and neurochemical processes to transfer from the brain's hippocampus to the neocortex for permanent 'consolidation'.

• Before the Consolidation process is complete, neuronal traces remain fragile.
• This rapid initial decline is explained by Trace Decay Theory, where memory traces fade swiftly if not consolidated.

Therefore, option b is the correct scientific and pedagogical explanation.
