Answer:
Consolidation theory
Step-by-step explanation:
Consolidation theory is described as the process or phenomenon through which an individual's brain tends to convert the short-term memories of the person into long-term memories. According to theory, an individual's or human being's brain is capable of storing short-term memories for more or less thirty seconds. In case, a person is trying to remember anything which is considered as important to him or her then the important information is supposed to move-on to the long-term memory.
The question above describes that Janet subscribes to the consolidation theory.
