support for cdf theory 2

• tulving and psotka 1971
• made pps learn lists of words, which the lists were divided into categories that acted as a cue
• pps were made to learn between 1-6 lists of words
• were asked to recall the lists in either free recall or cued recall
• researchers found that in free recall participants with more lists to learn recalled fewer words, suggested there was memory interference
• found that pps recalled more words when cued recall than in non cued recall
• this supports the cue dependent forgetting theory
• in the cued recall the number of lists didn't affect recall
• they concluded that forgetting was due to the absence of retrieval cues, not memory interference
