“…the inability to sufficiently differentiate the representations of different events owing to the relatively low learning rate, only a weak familiarity signal should be elicited by items repeated within the same context. This proposed increase in recollection is corroborated by a recent study asking the participants to memorize words that were presented either once (weak words) or three times (strong words) during a study phase (Finnigan, Humphreys, Dennis, & Geffen, 2002).…”

“…This peak represents the early automatic stage of word-processing, that is, the processing of welllearned stimuli such as letter strings (Hillyard et al, 1998). Consistent with previous ERP studies (e.g., Finnigan et al, 2002;Rugg et al, 1998), the 300-500 ms window was utilized to represent the N400 and the 500-to 800-ms window to represent the LPC.…”

“…Hence, the increasing ERP positivity in response to an increasing number of repetitions may reflect a graded process: the stronger the memory trace, the more positive is the ERP in the 500-to 800-ms time window. Finnigan et al (2002) manipulated memory strength by having their participants memorize words that were presented either once (weak words) or three times (strong words) during a study phase. At test, ERPs to correct old decisions after the presentation of strong words were more positive-going than ERPs to correct old decisions after the presentation of weak words.…”

Changes in brain electrical activity during extended continuous word recognition

et al. 2005

Twenty healthy subjects (10 men, 10 women) participated in an EEG study with an extended continuous recognition memory task, in which each of 30 words was randomly shown 10 times and subjects were required to make old vs. new decisions. Both event-related brain potentials (ERPs) and induced band power (IBP) were investigated. We hypothesized that repeated presentations affect recollection rather than familiarity.For the 300-to 500-ms time window, an dold/newT ERP effect was found for the first vs. second word presentations. The correct recognition of an doldT word was associated with a more positive waveform than the correct identification of a new word. The old/new effect was most pronounced at and around the midline parietal electrode position. For the 500-to 800-ms time window, a linear repetition effect was found for multiple word repetitions. Correct recognition after an increasing number of repetitions was associated with increasing positivity. The multiple repetitions effect was most pronounced at the midline central (Cz) and fronto-central (FCz) electrode positions and reflects a graded recollection process: the stronger the memory trace grows, the more positive the ERP in the 500-to 800-ms time window. The ERP results support a dual-processing model, with familiarity being discernable from a more graded recollection state that depends on memory strengths.For IBP, we found dold/newT effects for the lower-2 alpha, theta, and delta bands, with higher bandpower during doldT words. The lower-2 alpha dold/newT effect most probably reflects attentional processes, whereas the theta and delta effects reflect encoding and retrieval processes. Upon repeated word presentations, the magnitude of induced delta power in the 375-to 750-ms time window diminished linearly. Correlation analysis suggests that decreased delta power is moderately associated with faster decision speed and higher accuracy. D

“…hits in signal-detection terms, not misses, and usually not false alarms (but see Düzel, Yonelinas, Mangun, Heinze, & Tulving, 1997). There have, however, been dissenting opinions concerning the two-process account (Finnigan, Humphreys, Dennis, & GeVen, 2002;Yovel & Paller, 2004), which have questioned the dissociations of parietal and early frontal eVects or their associations with recollection and familiarity.…”

Conceptual and perceptual memory: Retrieval orientations reflected in event-related potentials

2006

In memory retrieval, search can be guided by mental sets towards diVerent subsets of the available evidence. Such retrieval orientations have been suggested to leave an imprint on event-related potentials (ERPs). The present study aimed at characterizing orientations towards perceptual and conceptual evidence in a recognition task, where pictures and words were studied. In the recognition test, items were presented in either the same format as at study or in the opposite format. A between-subjects manipulation modiWed the task, instructing an Exclusion group to endorse only items that preserved their format from study, and an Inclusion group to endorse both formats of a studied item. It was hypothesized that exclusion instructions would instil a perceptual and inclusion instructions a conceptual orientation. As a corollary, instructions were expected to dissociate the high end from the low end of the picture-word mirror eVect. This expectation was conWrmed in a behavioural experiment. In an ERP experiment, retrieval orientations were examined in their eVects on correct rejec- G. Stenberg et al. / Acta Psychologica 122 (2006) 174-205 175 further suggest that the examined old-new eVects in ERPs are mainly linked to voluntary aspects of memory, even in a task where involuntary memory exerts eVects on reaction times.
