“…5) correlates with the degree to which subjects must closely monitor modest differences in item familiarity, an orientation that is particularly important when contextual recollection is unavailable or non-diagnostic. This interpretation is consistent with (a) demonstrations that involvement of right frontopolar and dorsolateral PFC during yes-no recognition appears to depend on the subject's expectancy regarding the ratio of old to new items on the test list [24], (b) neuropsychological evidence showing an inordinately high false recognition rate in a patient with right PFC damage [58,59], (c) ERP and fMRI evidence implicating right PFC with acontextual "know" and low confidence recognition responses [21,25,60], and (d) ERP data showing preferential involvement at electrodes over right PFC during discrimination following shallow compared to deep encoding [13].…”

Memory orientation and success: separable neurocognitive components underlying episodic recognition

et al. 2003

Episodic recognition can be based on recollection of contextual details, on a sense of recent encounter, or some combination of the two. According to several cognitive models, selectively attending to these distinct aspects of memory may require different retrieval orientations and result in different neural responses depending upon whether or not retrieval is successful. Using event-related fMRI, we examined retrieval orientation by having subjects discriminate between two test words in one of two manners. During source recollection, they selected the member of the pair previously associated with a particular encoding task. In contrast, recency judgment required selection of the most recently encountered item of the pair, regardless of how it had been encoded. Furthermore, successful and unsuccessful trials within each retrieval task were contrasted to determine whether retrieval success effects occurred in overlapping or dissimilar neural populations compared to those associated with each retrieval orientation. The results revealed distinct lateral prefrontal and parietal activations that distinguished attempted source recollection from judgments of relative recency; these orientation effects were largely independent of retrieval success. In contrast, medial temporal lobe structures (hippocampus and parahippocampal gyrus) were differentially more active during successful recollection of encoding context, showing similar reduced responses during failed source recollection and judgments of recency. These results indicate that different memory orientations recruit distinct prefrontal and parietal networks and that the recovery of episodic context is associated with the hippocampus and surrounding medial temporal cortices.

“…However, items that are more familiar for a variety of reasons show earlier and/ or stronger activity than less familiar items, including in our study perceptual matching, consistent with Schloerscheidt and Rugg (2004). In addition to prior study, greater familiarity may be related to greater confidence (Woodruff et al, 2006), greater gist memory (Curran et al, 2001;Duzel et al, 1997;Goldmann et al, 2003), and greater fluency (Wolk et al, 2004(Wolk et al, , 2005. (It should also be noted that some researchers view this 300 to 500 ms modulation of activity as related to conceptual priming, rather than familiarity (Voss & Paller, 2006).…”

The worth of pictures: Using high density event-related potentials to understand the memorial power of pictures and the dynamics of recognition memory

2007

To understand the neural correlates of the memorial power of pictures, pictures and words were systematically varied at study and test within subjects, and high-density event-related potentials (ERPs) were recorded at retrieval. Using both conventional and novel methods, the results were presented as ERP waveforms, 50 ms scalp topographies, and video clips, and analyzed using t-statistic topographic maps and nonparametric p-value maps. The authors found that a parietally-based ERP component was enhanced

“…The rationale behind identifying these two components with processes of familiarity and recollection comes from two sources: First, the later parietal positivity is observed to be greater when participants make "remember" judgments than when they make "know" judgments (Düzel, Yonelinas, Mangun, Heinze, & Tulving, 1997); second, the later parietal positivity is selectively associated with correct source memory judgments (Wilding & Rugg, 1997).…”

ii Acknowledgements First, I extend my thanks to my committee members for their time, consideration, and guidance. I would especially like to thank my advisors, Rich Shiffrin and Mike Jones, for first convincing me to come to Indiana, making me feel welcome, and guiding me into the world I now inhabit. I must also thank Isaiah Harbison, Michael Dougherty, and Sharona Atkins for introducing me to the very idea of mathematical psychology and for teaching me and trusting me. show how the dynamic model can be extended to account for paradigms like associative recognition and list discrimination, leading to another novel test of the presence of recall-like processes. Associative recognition, list discrimination, recognition of similar foils, and source exclusion are all better explained by the formation of a compound cue rather than recall, although source memory is found to be better modeled by a recall process.
