The phenomenon of amnesia during infancy refers to the inability of infants to remember the time that occurred in the first two or three years of life. The previous explanation of this phenomenon is that infants cannot form a lasting representation of their own experience during this period That is, there is no related memory, so early memory cannot be used. However, recent research has found that this is not the case. Infants can recall earlier experiences and can recall them for a considerable period of time during infancy. Therefore, Researchers believe that not all babies have memory loss. The implicit assumptions in the above inference are:. ["Baby's short-term memory is better than long-term memory.", 'Representation of own experience and memory are closely related.', 'Being able to recall relevant experiences means that there must be memories.', 'Amnesia is often caused by difficulty in extracting memory cues.']
