Tulving and Pearlstone
there are two reasons why people forget
the memory trace was no longer available
the memory trace was inaccessible
the CI tries to address the second issue
encoding specificity theory
retrieval depends on association between target memory trace and how similar environment is to encoding environment
multiple trace theory
each memory entails multiple ,memory codes. when accessed and fed to the output system they reconstruct the original event
schema theory
the extent to which an event fits with script may affect our memory of it
