“…(2) Are these neural correlates of orientation, should they exist, distinct from the neural correlates of effort? As noted by Rugg and Wilding (2000), however, evidence addressing these questions is sparse because almost all potentially relevant studies have confounded either orientation and effort or pre-and postretrieval processing (by failing to separate neural activity elicited by cues eliciting successful vs. unsuccessful retrieval; e.g., Heil, Rösler, & Hennighausen, 1996). Findings from two ERP studies in which these confounds were avoided suggest that different retrieval orientations are neurally dissociable (Johnson, Kounios, & Nolde, 1997;Wilding, 1999; see also Ranganath & Paller, 1999), but the findings do not speak to the question of whether the effects of orientation vary according to effort.…”

The neural correlates of retrieval orientation-the differential processing of retrieval cues according to the form of the sought-for information-and retrieval effort were investigated in a factorial design. ERPs elicited by test words were recorded during four recognition memory tests. Orientation was manipulated by varying study material: The study phases preceding two of the tests employed pictures, whereas the study phases preceding the other two tests employed words. Effort was manipulated by varying difficulty, using a combination of the variables of length of study list and study-test interval. ERPs elicited by correctly classified new test words were sensitive to both the study material and, to a much lesserextent, the difficulty of manipulations. Whereas difficulty effects onset early and were shortlived, the effects of study material onset later, extended for several hundred milliseconds, and did not vary according to difficulty. It was concluded that retrieval orientation exerts a major influence on the processing of recognition memory test items.

“…The nature of the late effect-Fan 2 pairs producing more negative voltages than Fan 1 pairs over the frontal scalp-is similar in some respects to the negative slow potential observed by Heil et al (1996). Nyhus and Curran (2009) also reported an effect of fan on ERPs over the frontal scalp.…”

“…Nyhus and Curran (2009) also reported an effect of fan on ERPs over the frontal scalp. Our effect was right-lateralized, whereas Nyhus andCurran (2009) andHeil et al (1996) found that the effect of fan was maximal over the left hemisphere. Our experiment differs from Heil et al (1996) in two important ways.…”

Abstract■ In this study, we investigated the stages of information processing in associative recognition. We recorded EEG data while participants performed an associative recognition task that involved manipulations of word length, associative fan, and probe type, which were hypothesized to affect the perceptual encoding, retrieval, and decision stages of the recognition task, respectively. Analyses of the behavioral and EEG data, supplemented with classification of the EEG data using machinelearning techniques, provided evidence that generally supported the sequence of stages assumed by a computational model developed in the Adaptive Control of Thought-Rational cognitive architecture. However, the results suggested a more complex relationship between memory retrieval and decision-making than assumed by the model. Implications of the results for modeling associative recognition are discussed. The study illustrates how a classifier approach, in combination with focused manipulations, can be used to investigate the timing of processing stages. ■

“…This material specificity in the EEG has already been shown for retrieving faces and spatial positions of the same type as used here (Khader, Heil, & Rösler, 2005; see also Mecklinger, 1998). Therefore, slow waves can be utilized to measure the retrieval of material-specific representations from LTM (see also, e.g., Heil, Rösler, & Hennighausen, 1996). The combination of the direct measure of neural activation via EEG with the precise localization provided by fMRI allows to "cross-validate" the found effects with different methods and to derive a coherent picture of the neural processes underlying interference during LTM retrieval.…”

Abstract■ Remembering is more than an activation of a memory trace.As retrieval cues are often not uniquely related to one specific memory, cognitive control should come into play to guide selective memory retrieval by focusing on relevant while ignoring irrelevant information. Here, we investigated, by means of EEG and fMRI, how the memory system deals with retrieval interference arising when retrieval cues are associated with two material types (faces and spatial positions), but only one is task-relevant. The topography of slow EEG potentials and the fMRI BOLD signal in posterior storage areas indicated that in such situations not only the relevant but also the irrelevant material becomes activated. This results in retrieval interference that triggers control processes mediated by the medial and lateral PFC, which are presumably involved in biasing target representations by boosting the task-relevant material. Moreover, memorybased conflict was found to be dissociable from response conflict that arises when the relevant and irrelevant materials imply different responses. The two types of conflict show different activations in the medial frontal cortex, supporting the claim of domain-specific prefrontal control systems. ■
