“…Although this manipulation did not affect participants' memory performance, presumably because of the overall high level of accuracy, it seems plausible to assume that imagined items contain a larger amount of potential retrieval cues established during encoding than perceived items. The present findings, therefore, offer support for the proposal put forward in previous studies [51,72,75] that the old/new effect is sensitive to the quality or amount of contextual information retrieved from memory. However, for reasons discussed above, a prerequisite for such an explanation is that the compared ERP averages do not include an unequal proportion of trials on which recollection was missing (e.g.…”

“…For example, Curran [15] reported that while both studied words and similar words (switched plurality between study and test) showed the frontal effect, only studied words were associated with the parietal effect. Furthermore, the parietal effect is of greater magnitude for items that participants "remember" (item + context retrieval) relative to those that participants merely "know" (item retrieval only) as previously studied [17,65] and for items correctly assigned to their study context [72][73][74]76], thereby strengthening the link to recollection.…”

“…Interpreted within the context of dual-process models, an early (300-500 ms post-stimulus) old/new effect has been linked to familiarity and is assumed to evolve from an attenuation of a frontal N400-like component for old items [14,15,39,41,56], whereas the enhancement of a late positive component (400-800 ms), typically, maximal at left parietal regions (but see, e.g. [69] for a spatially widespread effect) is held to index recollection [3,46,51,65,[72][73][74]76]. For example, Curran [15] reported that while both studied words and similar words (switched plurality between study and test) showed the frontal effect, only studied words were associated with the parietal effect.…”

Memory for perceived and imagined pictures—an event-related potential study

et al. 2002

Event-related potentials (ERPs) and behavioural measures were used to investigate recognition memory and source-monitoring judgements about previously perceived and imagined pictures. At study, word labels of common objects were presented. Half of these were followed by a corresponding picture and the other half by an empty frame, signalling to the participants to mentally visualise an image. At test, participants in a source-monitoring task made a three-way discrimination between new words and words corresponding to previously perceived and imagined pictures. Participants in an old/new-recognition task indicated whether test words were previously presented or not. In both tasks, correctly identified old items elicited more positive-going ERPs than correctly judged new items. This widely distributed old/new effect was found to have an earlier onset and to be of a greater magnitude for imagined than for perceived items. Task (source versus item-memory) affected the old/new effects over prefrontal areas and the reaction times to remembered old items. The present findings are consistent with the view that a greater amount, or a different type, of information is necessary for accurate source-memory judgements than for correct recognition, and moreover, that different types of source-specifying information revive at different rates. In addition, the results add weight to the view that the late widespread ERP-old/new effect is sensitive to the quality or the amount of information retrieved from memory.

“…This could be due to less informational content in the imagined pictures in accordance with the idea that self-generated events generally contain less perceptual and spatiotemporal information than perceived events (e.g., see discussion of Marsh et al, 2001). In addition, ERP studies have supported the notion that parietal old/new effects increase in a graded fashion with the amount or quality of information retrieved (e.g., Wilding, 2000).…”

Isolating the retrieval of imagined pictures during episodic memory: activation of the left precuneus and left prefrontal cortex

The posterior medial parietal cortex and the left prefrontal cortex have both been implicated in the recollection of past episodes. In order to clarify their functional significance, we performed this functional magnetic resonance imaging study, which employed event-related source memory and item recognition retrieval of words paired with corresponding imagined or viewed pictures. Our results suggest that episodic source memory is related to a functional network including the posterior precuneus and the left lateral prefrontal cortex. This network is activated during explicit retrieval of imagined pictures and results from the retrieval of item-context associations. This suggests that previously imagined pictures provide a context with which encoded words can be more strongly associated.

“…A variety of evidence links the left parietal old/new effect to recollection (for reviews, see Friedman & Johnson, 2000;Rugg & Allan, 2000). For example, the effect is greater when elicited by recognized items attracting correct, rather than incorrect, source judgments (Trott, Friedman, Ritter, Fabiani, & Snodgrass, 1999;Wilding, 2000;Wilding & Rugg, 1996), items attracting remember, as opposed to know, judg-…”

Strategic influences on recollection in the exclusion task: Electrophysiological evidence

One assumption underlying the use of the exclusion task as part of the process dissociation procedure is that studied items are successfully excluded only when they are recollected. The present study employed event-related potentials (ERPs) to demonstrate that successful exclusion does not necessarily require recollection. In two experiments, the study tasks for to-be-excluded items were identical, but the tasks employed with target items differed, giving better memory for these items in Experiment 1 than in Experiment 2. Successfully excluded items elicited the ERP signature for recollection-the left parietal old/new effect-in Experiment 2 only. These findings indicate that the subjects adopted different retrieval strategiesin the two experiments. It is suggested that they made more use of source information about to-be-excluded items in the second experiment than in the first.
