This thesis tested whether using meaningful trigraphs in the three letter memorization paradigmused by Ecker, Oberauer, and Lewandowsky (2014) changed the nature of working memoryupdate. Participants were undergraduate students from a mid-sized midwestern US university.The results replicated Ecker, Oberauer, and Lewandowsky's findings in all conditions whereparticipants memorized a non-meaningful trigraph (memorizing a trigraph that was one letterdifferent than the previous trigraph was significantly faster than memorizing a trigraph with twochanges and memorizing a trigraph with three changes was faster than making two changes butslower than one change). Compared to the control condition there was a compression of reactiontimes in the meaningful condition. Two and three changes were significantly faster in themeaningful condition compared to the not meaningful condition (p < .05) and one change wasnon-significantly slower (p = .19). There was no main effect of direction of changes (p = .18).The inclusion of meaningful trigraphs did not appear to change the pattern of working memoryupdate, as might be predicted by a serial updating paradigm. Possible explanations and futureresearch directions are discussed in the discussion. |
