source memory and familiarity

In some cases, déjà vu may be understood within the context of research on human recognition memory. Thus, tests of source memory are generally thought to require recollection of contextual information associated with … memory for the spatiotemporal context in which stimuli occurred or the mental associations triggered by their occurrence (“source” memory) (Johnson et al., 1993). The results revealed two distinct neural correlates of source recognition: a frontally distributed positivity that was associated with familiarity-based source memory in the high-unitization condition only and a parietally distributed positivity that was associated with recollection-based source memory in both the high- and low-unitization conditions.

Recognition memory can be supported by the processes of recollection and familiarity. Keywords: source memory, familiarity, unitization, recollection, ROCs Source memory provides information about the conditions un-der which an item was previously encountered. (2005) note that in their color word task, participants may have been trying to remember both word and Recollection is recovery of qualitative information about a prior event. • 11:00: “Dissociating familiarity and item memory from recollection and source memory after focal damage in the perirhinal cortex vs. the hippocampus”, Georgios P. D. Argyropoulos et al. Dissociable neural correlates for familiarity and recollection during the encoding and retrieval of pictures. How familiarity can enhance someone's sense of attractiveness. Recognition memory can be subdivided into two component processes: recollection and familiarity, sometimes referred to as "remembering" and "knowing", respectively. p. 222-226. Modulations of oscillatory electroencephalogram (EEG) activity in the induced gamma and theta frequency ranges (induced gamma and theta band responses; iGBRs: >30 … Electrophysiological correlates of retrieval orientation are associated with source memory performance, Associative recognition processes are modulated by the semantic unitizability of memoranda, Associative Recognition Processes Are Modulated by Modality Relations, Emotion impairs extrinsic source memory—An ERP study, Unitization improves source memory in older adults: An event-related potential study, Examining Event-Related Potential (ERP) Correlates of Decision Bias in Recognition Memory Judgments. Experiment 3 replicated the results using a within-subjects manipulation of spatial vs. color source. Paller, ... memory devoid of any recall of source information. Process dissociation of familiarity and recollection in children: response deadline affects recollection but not familiarity. Learn vocabulary, terms, and … Specifically, déjà vu may sometimes result from familiarity-based recognition, or recognition that is based on feelings of familiarity that occur without identification of their source. ► The effects are seen both behaviorally and in recognition memory ERP components. There is vigorous debate about how these processes are conceptualized, how they contribute to memory judgments, and which brain regions support them. ► Familiarity can support associations between different types of information. All groups responded faster to new items than old, and ERP responses to general novelty were similar across the groups — although children showed a left-frontal focus that may reflect the transition from analytic to a more holistic processing approach. Crucially, item repetition impaired, rather than improved, source memory for preexperimentally novel items when these items had been preexposed to participants before the three-phase procedure. It is widely hypothesized that separate recollection and familiarity processes contribute to recognition memory. Patients with schizophrenia demonstrated impaired familiarity-based and intact source-based memory performance. Overall, the results suggest that familiarity's contribution to extrinsic source monitoring depends on the type of source information being remembered. Learning, memory, and cognition, By clicking accept or continuing to use the site, you agree to the terms outlined in our. When Memory Does Not Fail: Familiarity-Based Recognition in Mild Cognitive Impairment and AlzheimerÕs Disease Carmen E. Westerberg, Ken A . It has been debated whether source information for a studied item (i.e., contextual associations from when the item was previously encountered) is only accessible through recollection, or whether familiarity can contribute to successful source recognition. with source memory based on an all-or-none recollection process (Yonelinas, 1999), ... responses on recollection rather than familiarity. D) provides one of the important sources for recognition. This entry was posted in Uncategorized on June 14, 2015 by Joseph A Bernard. To resolve these conflicting results, we examined the modulatory role of preexperimental stimulus familiarity in the relationship between item repetition and new source memory formation by orthogonally manipulating preexperimental stimulus familiarity and intraexperimental item repetition. Recollection is the retrieval of details associated with the previously experienced event. Event-related potential correlates of item and source memory strength. Familiarity and recollection are thought to be separate processes underlying recognition memory. C) is promoted by deep processing. The effects of unitization on familiarity-based source memory: testing a behavioral prediction derived from neuroimaging data. (Along these lines, Siedlecki et al. In conclusion, the present results suggest that familiarity is sensitive to location information that was not explicitly unitized with associated items, which adds to the existing literature regarding familiarity's involvement in source memory (e.g., Diana et al., 2008, Ecker et al., 2007a, Ecker et al., 2007b, Mayes et al., 2004, Yonelinas et al., 1999), and provides evidence against the view that item–location … Chapter 8 – Everyday Memory and Memory Errors. • source of the memory (episodic) - source memory and familiarity come from B) is established by "relational" or "elaborative" rehearsal.

Psychology Definition of SOURCE MEMORY: Being able to remember the origin of a memory or of the knowledge of how we came to have that memory. Although it is generally believed that familiarity does not contribute to source memory, recent behavioral studies have suggested that familiarity may also support source recognition when item and source information are integrated, or “unitized,” during study (Diana, Yonelinas, and Ranganath, 2008). (University of Oxford, University of Padua, King’s College London, Cardiff University, University of Cambridge, University Hospital Marqués de Valdecilla). Event-related potentials (ERPs) dissociate these processes, with an early (approximately 300-500ms) frontal effect relating to familiarity (the FN400) and a later (500-800ms) parietal old/new effect relating to recollection.

K judgments typically entail a sense of familiarity, in the absence of information about the source of that familiarity (such as when one recognizes a face, but Extrinsic source associations were examined in three experiments involving memory judgments for pictures of common objects. The researchers speculate that the mechanism that seems to underlie the benefits of mindfulness — judgment-free thoughts and feelings — might also affect people's ability to determine the origin of a given memory (source memory), because they have become less able to distinguish between externally occurring events and internally generated events. It has been shown that familiarity can assist in perceptual source monitoring when the source attribute is an intrinsic property of the item (e.g., an object's surface color), but few studies have examined its contribution to recognizing extrinsic source associations. Event-related potentials (ERPs) dissociate these processes, with an early (approximately 300-500ms) frontal effect relating to familiarity (the FN400) and a later (500-800ms) parietal old/new effect relating to recollection. Familiarity and recollection are thought to be separate processes underlying recognition memory. In Experiment 1, source information was spatial and results suggested that familiarity contributed to accurate source recognition: the FN400 ERP component showed a source accuracy effect, and source accuracy was above chance for items judged to only feel familiar.
