Concept information

Preferred term

acid bath theory  


  • According to this theory, forgetting a memory trace in short-term memory occurs during the storage phase of the information, and more specifically, during the retention interval. Forgetting is a function of the number of stored items (by analogy, the amount of acid) and their similarity (by analogy, the acid concentration).
