Similar phenomena, different mechanisms: semantic and phonological false memories are produced by independent mechanisms.
The Deese/Roediger-McDermott paradigm can produce high levels of false remembering for lists of both semantic and phonological associates. The present study investigated whether similar mechanisms mediate false memories with these two types of lists. Experiment 1 measured the relationship between levels of false memory obtained with lists of semantic and phonological associates. The results indicated little correlation between false memories generated with the two types of associates. Experiment 2 used a between-subjects design to determine whether the absence of a significant correlation in Experiment 1 was a consequence of the relatively low levels of false memory observed in that experiment. The results indicated similar proportions of false memories in Experiments 1 and 2, suggesting that the within-subjects design in Experiment 1 did not reduce the overall levels of false recall or recognition. The results are discussed in terms of their implications for the independence of the mechanisms mediating different types of false memories.
