Researcher: All defects in short-term memory are caused by a malfunction of a part of the brain called the hippocampus  In short-term memory, the mind holds a piece of information for only a few moments, after which it is either stored in long-term memory or forgotten  Learning is the accumulation of new information in long-term memory
Thus, whenever a child exhibits a learning deficit, the hippocampus is malfunctioning
presumes, without giving justification, that all learning deficits in children involve shortterm memory
