“…Using fMRI, Dew and Cabeza (2013) found that reduced activity in the perirhinal cortex, which, for decades, had been considered a hallmark of familiarity memory, was also observed for unstudied words that were primed during the test phase. These and several other findings (Gomes et al, 2016(Gomes et al, , 2017(Gomes et al, , 2019Wang et al, 2016) suggest that the neural substrates of accurate and fluency-based inaccurate recognition memory are likely mediated by a common neural network. Indeed, computational models have indicated that, if certain assumptions hold, a single-memory system is capable of supporting both recognition memory and fluency (Berry et al, 2008(Berry et al, , 2012.…”

“…Recent research has shown that fluency‐based inaccurate familiarity can trigger a similar brain mechanism to that which produces accurate familiarity (Dew & Cabeza, 2013; Gomes et al., 2019; Voss et al., 2012). One possibility could be that participants experienced enhanced perceptual fluency during the processing of certain novel pictures, which was then used as a cue for distinguishing old from new items (Johnston et al., 1985; Whittlesea, 1993).…”

Can pupillometry distinguish accurate from inaccurate familiarity?

Pupillometry, the measurement of pupil diameter, has become increasingly popular as a tool to investigate human memory. It has long been accepted that the pupil is able to distinguish familiar from completely novel items, a phenomenon known as "pupil old/new effect". Surprisingly, most pupillometric studies on the pupil old/ new effect tend to disregard the possibility that the pupillary response to familiarity memory may not be entirely exclusive. Here, we investigated whether the pupillary response to old items correctly judged familiar (hits; accurate familiarity) can be differentiated from the pupillary response to new items wrongly judged familiar (false alarms; inaccurate familiarity). We found no evidence that the two processes could be isolated, as both accurate and inaccurate familiarity showed nearly identical mean and across-time pupillary responses. However, both familiarity hits and false alarms showed pupillary responses unequivocally distinct from those observed during either recollection or novelty detection, which suggests that the pupil measure of familiarity hits and/or false alarms was sufficiently sensitive. The pupillary response to false alarms may have been partially driven by perceptual fluency, since novel objects incorrectly judged to be old (i.e., false alarms) showed a higher degree of similarity to studied images than items correctly judged as novel (i.e., correct rejections). Thus, our results suggest that pupil dilation may not be able to distinguish accurate from inaccurate familiarity using standard recognition memory paradigms, and they also suggest that the pupillary response during familiarity feelings may also partly reflect perceptual fluency.

“…Indeed, previous research has found that increasing the duration of the subliminal prime could influence the size of the PE (Holcomb, Reder, Misra, & Grainger, 2005). In the same line, recent studies have revealed that presenting primed item in blocks or randomly across trials influence how adults disqualify fluency (Gomes, Mecklinger, & Zimmer, 2019). It would be interesting to explore whether these types of procedure also affect children’s memory decisions.…”

“…This test was similar to that used to ensure familiar cartoons were processed more quickly than unfamiliar cartoons. Indeed, if primed items are processed more fluently than unprimed items, they should be identified more quickly during the judgment task (e.g., Glaser, 1992;Mitchell & Brown, 1988). The results revealed that the prime was successful in speeding response times.…”

Too Much Familiarity! The Developmental Path of the Fluency Heuristic in Children

We tested whether changes in attribution processes could account for the developmental differences observed in how children's use fluency to guide their memory decisions. Children ranging in age from 4 to 9 years studied a list of familiar or unfamiliar cartoon characters. In Experiment 1 (n = 84), participants completed a recognition test during which the perceptual fluency of some items was enhanced using a prime. In Experiment 2 (n = 96), participants completed a source recollection judgment on their recognition decisions. Primed items were recognized at a higher rate than unprimed items. However, while young children rely on fluency for all items, older children use fluency only for unfamiliar items. This pattern came together with a reduction in familiarity-based-but not recollection-based-memory responses.

“…Priming is a kind of implicit memory in which the processing of a stimulus during a learning phase leads to more accurate or faster response times(RTs) tothatstimulus when thesameresponseis made during a subsequent test phase (Richardson-Klavehn & Bjork, 1988;Roediger,1990;Tulving&Schacter,1990).Althoughsuchprimingis found even when conscious memory of the stimulus is absent (Gomes, Mecklinger, & Zimmer, 2019;Gomes, Montaldi, & Mayes, 2015;Hamann & Squire, 1997), it may sometimes support successful recognition memory (Gomes, Mecklinger, & Zimmer, 2017;Taylor & Henson, 2012;Voss, Lucas, & Paller, 2012).…”

We investigated stimulus-response (S-R) memory links during object priming using a binary associative size judgement paradigm. At study, participants decided which of two objects was bigger in real life and, at test, made the same or the reverse judgement. We examined the effects of response congruence on item S-R priming in the associative paradigm. In Experiment 1, a task reversal manipulation had minimal impact on RT priming when classifications were congruent for both recombined objects between study and test. Experiment 2 found that RT priming was more disrupted by classification incongruence of the selected than of the nonselected item alone, with incongruence of the nonselected object having no effect on RTs. Experiment 3, however, found that classification incongruence of both items eliminated RT priming, indicating that a significant effect of classification incongruence for the nonselected item is only evident if both items are classification-incongruent. Finally, across all experiments, we found that accuracy was more sensitive than RTs to decision/action incongruence. We interpret these findings in light of a two-stream account of S-R priming, and suggest a few extensions to account for interactions between S-R links of recombined items.
