Conditions modifying memory : the von Restorff and the 'release' effects.
The research reported here centres on two interesting memory phenomena: the von Restorff and release effects. A variety cf
theoretical interpretations of these phenomena has been offered in the experimental literature, and it has sometiimes, indeed, been proposed that a single interpretation might account for both phenomena. A case can be made for dividing up the theoretical interpretations into those emphasizing encoding processes, those emphasizing storage and rehearsal processes, and those emphasizing the processes of retrieval.
With the above distinction in mind, a total of seven experiments were conducted; some variables were investigated in relation to both of the phenomena in the attempt to ascertain more closely the similarity betweeen the two effects.
In essence, the results obtained indicated that a common process does not underlie the two phenomena: the con Restorff effect appears to depend upon encoding processes, whereas the release effect does rather seem to depend upon retrieval processes.
