2.3. The emergence of episodic memory
Until now we have used the term declarative memory to refer to memories that depend upon the hippocampus. This is largely because ‘declarative’ memory and ‘hippocampal-dependent’ memory were once viewed as synonymous and, although controversial, declarative memory (via the use of the parameter and amnesia filters) was relatively easy to assess in infants, as described earlier. However, it is highly likely that there is more to hippocampal-dependent memory than declarative processes, and in recent years the type of memory that has been most associated with the hippocampus is episodic memory – the memory for our personal past experiences. Hence, in order to be truly convinced that young infants are utilising a hippocampal-dependent memory system then we need to also look for evidence of episodic memory in this population.
