Abstract
-
The roles of visual imagery, depth of processing, and other factors affecting hypermnesia (increasing memory recall over successive trials) were examined in a number of experiments.;Several pieces of evidence were presented that indicate that visual imagery processes do not in themselves explain the occurrence of hypermnesia. These include the finding of hypermnesia for low imagery words and for items in long-term memory that are not apt to be imaged. In addition in one experiment indicators of visual imagery did not correlate significantly with subjects' individual levels of hypermnesia.;As other recent studies have suggested, semantic elaboration was shown to facilitate hypermnesic recall. However, in the final analysis it was concluded that the occurrence of hypermnesia cannot be described as being a depth of processing phenomenon any more than it can be described as being a visual imagery phenomenon.;As a possible alternative to visual imagery and depth of processing explanations of hypermnesia, levels of hypermnesia may be said to be determined by levels of memorial availability. As support for this position, it was found that recognition memory levels correlated significantly with levels of hypermnesia for items in long-term memory. An availability explanation of hypermnesia is parsimonious because it can account for the effects of visual imagery, depth of processing, and category size.;The role of recall time was examined by varying the amount of time subjects were allowed on a repeated recall task. It was found that level of hypermnesia was unaffected by the length of recall periods.;Finally, it was found that the amount of psychological time subjects are given between recall periods is an important determinant of level of hypermnesia, whereas the mere passage of (real) time is not.
