“…More positive amplitudes for correct relative to incorrect source memory decisions at frontal sites and in similar time ranges have been interpreted as reflecting an FN400 (e.g. Groh-Bordin et al, 2006;Mollison & Curran, 2012), a component which has been interpreted to indicate familiarity (Curran, 2000). For the present study, an interpretation of the early ERP effect in terms of familiarity-based processes appears unlikely.…”

In three experiments, we used event-related brain potentials (ERPs) to examine influences of fluency on source memory for famous names. At test, names were presented visually throughout, whereas visual or auditory presentation was used at learning. In Experiment 1, source decisions following old/new judgments were more accurate for repeated relative to non-repeated visually and auditorily learned names. ERPs were more positive between 300 and 600 ms for visually learned as compared to both auditorily learned and new names, resembling an N400 priming effect. In Experiment 2, we omitted the old/new decision to more directly test fast-acting fluency effects on source memory. We observed more accurate source judgments for repeated versus non-repeated visually learned names, but no such effect for repeated versus non-repeated auditorily learned names. Again, an N400 effect (300-600 ms) differentiated between visually and auditorily learned names. Importantly, this effect occurred for correct source decisions only. We interpret it as indexing fluency arising from withinmodality priming of visually learned names at test. This idea was further supported in Experiment 3, which revealed an analogous pattern of results in older adults, consistent with the assumption of spared fluency processes in older age. In sum, our findings suggest that fluency affects personrelated source memory via within-modality repetition priming in both younger and older adults.

“…Squiggles were presented on a computer monitor in black on a white background within a square subtending ∼5°of visual angle. Squiggles were taken from a total set of 300 squiggles from a recent study of explicit memory (Groh-Bordin et al 2006) and were created via hand-deformation of a square, circle, or triangle.…”

“…A method that might limit the influence of conceptual priming on neural correlates of explicit memory is to use novel visual shapes having little inherent meaning and, thus, a minimal capability to support conceptual priming (Curran et al 2002;Groh-Bordin et al 2006). Nevertheless, if conceptual priming can occur even under such circumstances, this method would be problematic.…”

During episodic recognition tests, meaningful stimuli such as words can engender both conscious retrieval (explicit memory) and facilitated access to meaning that is distinct from the awareness of remembering (conceptual implicit memory). Neuroimaging investigations of one type of memory are frequently subject to the confounding influence of the other type of memory, thus posing a serious impediment to theoretical advances in this area. We used minimalist visual shapes (squiggles) to attempt to overcome this problem. Subjective ratings of squiggle meaningfulness varied idiosyncratically, and behavioral indications of conceptual implicit memory were evident only for stimuli given higher ratings. These effects did not result from perceptual-based fluency or from explicit remembering. Distinct event-related brain potentials were associated with conceptual implicit memory and with explicit memory by virtue of contrasts based on meaningfulness ratings and memory judgments, respectively. Frontal potentials from 300 to 500 msec after the onset of repeated squiggles varied systematically with perceived meaningfulness. Explicit memory was held constant in this contrast, so these potentials were taken as neural correlates of conceptual implicit memory. Such potentials can contaminate putative neural correlates of explicit memory, in that they are frequently attributed to the expression of explicit memory known as familiarity. These findings provide the first neural dissociation of these two memory phenomena during recognition testing and underscore the necessity of taking both types of memory into account in order to obtain valid neural correlates of specific memory functions.

“…In contrast, Groh-Bordin, Zimmer, and Mecklinger (2005), who also manipulated the orientation of picture stimuli, found RT congruency effects accompanied by a selective ERP congruency effect on the FN400 in a pure old-new task with no feature relevance (following incidental study). Employing a procedure similar to the one here, Groh-Bordin, Zimmer, and Ecker (2006) reported RT congruency effects when the color of objects was manipulated in an inclusion task with subsequent feature decision. Their behavioral findings were accompanied by attenuations of both early and late ERP old-new effects for incongruent items.…”
