Priming insights : the adaptive functions of false memories
|
Previous research has suggested that false memories can prime performance on
related implicit and explicit memory tasks. The present thesis first aimed to examine
whether false memories can have similar functions to those proposed for true
memories and whether they can be used to prime higher order cognitive processes,
namely, insight-based problem-solving. In a series of experiments, a false memory priming
paradigm was developed in which participants were asked to solve a number
of compound remote associate task (CRAT) problems, half of which had been primed
by the presentation of Deese/Roediger-McDermott (DRM) lists whose critical lure
was also the solution to the problem. The results showed that when the critical lure
was falsely recalled, eRA T problems were solved more often and significantly faster
than problems that were not primed by a DRM list, or when the critical lure was not
falsely recalled. The results also successfully pinpointed the locus of this false
memory priming effect to the study phase of the paradigm and extended the paradigm
to recognition measures of memory. The adaptive nature of false memories was also
explored using the paradigm, demonstrating that when more than one answer is
possible to solve a problem, false memories are capable of biasing problem solution
choice towards the critical lure. Results showed that when the critical lure was falsely
recalled, solutions to eRA T problems were significantly biased towards the critical
lure solution, when this answer was ordinarily the non-dominant solution. In a final
experiment, the paradigm was extended to an incidental processing task, with results
showing that false memories created out of survival processing are better at priming
eRA T problems than those from neutral processing. The implications of these results
are discussed with regard to the previous literature and theories underlying both
priming and false memories as well as the adaptive functions of false memories.
