Abstract. Traditionally, most event related potential (ERP) studies of memory retrieval have been reported during item-recognition tasks. Those studies lead to two well-known ERP memory components termed FN400 (familiarity) and LPC (recollection). Nevertheless, some critics have raised concerns regarding the actual meaning of that activity since it emerges as the result of contrasting two different memory traces (previously studied vs. seen for the first time), and it is registered after the target presentation. Therefore, they possibly depict operations not related to memory itself but some cognitive processes associated with recognition memory. Based on those critics, we propose an innovative approach to study electrophysiological activity underlying recognition memory. We compared two very similar tasks with only one of them requiring subjects to actively retrieve a “cue-target” pair of visual stimuli from memory, while the other task required subjects to recognize the target stimulus as equal/different to the cue. Because of this experimental manipulation, we assured that active memory retrieval processes take place between the presentation of the cue and the target stimuli for only one of the tasks. As a result, responses upon the targets can give us valuable information regarding ERP components associated with recognition based on memory retrieval. We found three components possibly related to brain computations necessary to achieve correct target recognition. A N200-like component linked to executive functions (inhibition) from frontal cortices, a P300-like component, related to the expectation of the target stimulus, and a P600-like component associated to recognition based on LTM retrieval. These results help us to understand the complexity behind ERP components associated with recognition memory.

Effect Of Age

Abstract Objectives Although research has identified age-by-emotion interactions in memory performance and in neural recruitment during retrieval, it remains unclear which retrieval processes are affected. The temporal resolution of event-related potentials (ERPs) provides a way to examine different component processes that operate during retrieval. Methods In the present study, younger and older adults encoded neutral and emotional images paired with neutral titles. ERPs were assessed during a recognition memory task in which participants viewed neutral titles and indicated whether each had been presented during encoding. Results An age-related posterior-to-anterior shift began in a time window typically associated with recollection-related processes (500–800 ms) while an age-by-emotion interaction occurred only during a later measurement window (800–1,200 ms). Discussion These findings suggest an effect of age on mechanisms supporting retrieval of episodic content, prior to post-retrieval processing. The potential relations to different types of detail retrieval are discussed. Further, the later age-by-emotion interactions suggest that age influences the effect of emotion on post-retrieval processes, specifically.

Abstract Prospective memory (PM) enables people to remember to complete important tasks in the future. Failing to do so can result in consequences of varying severity. Here, we investigated how PM error-consequence severity impacts the neural processing of relevant cues for triggering PM and the ramification of that processing on the associated prospective task performance. Participants role-played a cafeteria worker serving lunches to fictitious students and had to remember to deliver an alternative lunch to students (as PM cues) who would otherwise experience a moderate or severe aversive reaction. Scalp-recorded, event-related potential (ERP) measures showed that the early-latency frontal positivity, reflecting the perception-based neural responses to previously learned stimuli, did not differ between the severe versus moderate PM cues. In contrast, the longer-latency parietal positivity, thought to reflect full PM cue recognition and post-retrieval processes, was elicited earlier by the severe than the moderate PM cues. This faster instantiation of the parietal positivity to the severe-consequence PM cues was then followed by faster and more accurate behavioral responses. These findings indicate how the relative importance of a PM can be neurally instantiated in the form of enhanced and faster PM-cue recognition and processing and culminate into better PM.
