Resumen
[ENG]In the Deese–Roediger–McDermott (DRM) paradigm,
participants falsely recall or recognize a nonpresented
word (critical lure), highly associated with previously
studied words. As numerous DRM studies have found a
robust false memory effect at the behavioural level, eventrelated
potentials (ERPs) studies have searched for
possible overlapping in brain electrical activity between
true and false memory. Using the DRM paradigm, the
present experiment manipulated the sensory modality of
stimulus presentation (auditory vs. visual) in the study
phase to analyse the effect of modality match between
study and test on true and false recognition. Words were
therefore presented either visually or auditorily at study
and always visually at test. True recognition was found to
be significantly higher in the modality ‘match’ condition
(visual–visual) than in the ‘mismatch’ condition (auditory–
visual), whereas there was no modality-match effect on
false recognition of critical lures. A general, overlapping
was found between ERP correlates of true and false
recognition: FN400 (300–500 ms), left-parietal
(400–800 ms) and late right-frontal (1000–1500 ms) old/
new effects were similar for both studied words and critical
lures. No sensory modality-match effect was associated
with FN400 or left-parietal old/new effects. Only the late
right-frontal activity was modulated by modality
manipulation, with significantly more positive ERPs in the
modality-match condition. Sensory modality match of
stimulus presentation, therefore, dissociated true and
false recognition memory only at the behavioural level but
not at the ERP level. Overall, true and false recognition
memories seem to share common underlying
processes. NeuroReport 24:108–113 !c 2013 Wolters
