“…For instance, an early article establishing the role of LOC in visual processing of objects found that greater activation of this region during encoding of objects was associated with greater subsequent memory (Grill-Spector et al, 2000). Since that time, multiple studies have also shown that activation in these category-preferential regions is linked to individual differences in long-term memory performance (Hasinski & Sederberg, 2016; Kim, 2011; Bernstein, Beig, Siegenthaler, & Grady, 2002). Similarly, recent work in children and adults found that increased activation of the parahippocampal cortex for the encoding of complex visual scenes was associated with greater subsequent memory for those scenes (Chai et al, 2010).…”

“…Although associative memory formation and the neural mechanisms that support associative memory have been studied across development (DeMaster, Pathman, Lee, & Ghetti, 2014; DeMaster, Pathman, & Ghetti, 2013; Paz-Alonso, Bunge, Anderson, & Ghetti, 2013; Ghetti, DeMaster, Yonelinas, & Bunge, 2010), scant research has investigated the role of visual association cortex in the development of visual associative memory. Recent evidence shows that recruitment of visual association cortex during encoding is associated with memory performance (Hasinski & Sederberg, 2016; Wendelken, Baym, Gazzaley, & Bunge, 2011; Chai, Ofen, Jacobs, & Gabrieli, 2010; Xue et al, 2010; Grill-Spector, Kushnir, Hendler, & Malach, 2000), suggesting that secondary sensory areas may facilitate memory encoding by maintaining attention to the representation of the to-be-remembered stimulus. This study investigates neurodevelopmental changes in associative memory for faces and objects to determine whether visual processing regions that respond preferentially to particular stimuli (e.g., faces or objects) support developmental and individual differences in associative memory.…”

“…However, a recent work in adults has shown that activation in secondary sensory areas involved in the initial encoding of stimuli is also related to subsequent memory for those stimuli (Hasinski & Sederberg, 2016; Xue et al, 2010; Grill-Spector et al, 2000). Emerging evidence indicates that increased activation in category-preferential visual association cortex during encoding may be related to an increased ability to sustain that representation, underlying age-related increases in memory performance (Wendelken et al, 2011; Chai et al, 2010).…”

Associative learning underlies the formation of new episodic memories. Associative memory improves across development, and this age-related improvement is supported by the development of the hippocampus and pFC. Recent work, however, additionally suggests a role for visual association cortex in the formation of associative memories. This study investigated the role of category-preferential visual processing regions in associative memory across development using a paired associate learning task in a sample of 56 youths (age 6–19 years). Participants were asked to bind an emotional face with an object while undergoing fMRI scanning. Outside the scanner, participants completed a memory test. We first investigated age-related changes in neural recruitment and found linear age-related increases in activation in lateral occipital cortex and fusiform gyrus, which are involved in visual processing of objects and faces, respectively. Furthermore, greater activation in these visual processing regions was associated with better subsequent memory for pairs over and above the effect of age and of hippocampal and pFC activation on performance. Recruitment of these visual processing regions mediated the association between age and memory performance, over and above the effects of hippocampal activation. Taken together, these findings extend the existing literature to suggest that greater recruitment of category-preferential visual processing regions during encoding of associative memories is a neural mechanism explaining improved memory across development.

“…The encoding variability hypothesis predicts that better memory is achieved when the representations were more dissimilar across repetitions, and that spacing the repetitions enhances memory by further increasing the dissimilarity. Contrary to these predictions, however, studies using fMRI and representational similarity analysis have found that greater similarity rather than dissimilarity in neural representations across repetitions was associated with better subsequent memory (Xue et al, 2010;Ward et al, 2013;Hasinski and Sederberg, 2016;Zheng et al, 2018). Other studies have further demonstrated that reactivations of prior representations during subsequent learning contribute to successful memory encoding (Kuhl et al, 2010;Lu et al, 2015;Koen and Rugg, 2016).…”

Spaced Learning Enhances Episodic Memory by Increasing Neural Pattern Similarity Across Repetitions

Spaced learning has been shown consistently to benefit memory compared with massed learning, yet the neural representations and processes underlying the spacing effect are still poorly understood. In particular, two influential models (i.e., the encoding variability hypothesis and the study-phase retrieval hypothesis) could both model behavioral performance very well, but they make opposite hypotheses regarding the spacing effect's neural mechanisms. The present study attempted to provide empirical neural evidence to adjudicate these competing hypotheses. Using spatiotemporal pattern similarity (STPS) analysis of EEG data, this study investigated whether and how repetition lags (massed/short-spaced/long-spaced) modulated the STPS's contribution to episodic memory encoding in male and female human participants. The results revealed that greater item-specific STPS in the right frontal electrodes at 543-727 ms after stimulus onset was associated with better memory performance. More importantly, this STPS was larger under the spaced-learning condition than the massed-learning condition and partially mediated the spacing effect on memory performance. In addition, we found that massed learning was associated with stronger repetition suppression in the N400 component that reflected momentary retrieval strength, but reduced activity in the late positive component that was associated with memory retrieval. These results suggest that spaced learning improves long-term memory by increasing retrieval effort and enhancing the pattern reinstatement of prior neural representations, which may be achieved by reducing the momentary retrieval strength as the extended repetition lags might help to eliminate the residual representation in working memory. Significance StatementAs one of the most ubiquitous and fundamental phenomena in the history of memory research, the spacing effect provides an important window into understanding how enduring memory is formed in the brain and how different practice strategies could modulate these mechanisms to affect memory performance. By leveraging the neural representational analysis on scalp EEG data, the current study provides the first empirical data to show that spaced learning enhances memory by improving the spatiotemporal similarity that occurs at a late time window. Our results support the study-phase retrieval hypothesis but not the encoding variability hypothesis and emphasize the role of neural pattern reinstatement in strengthening memory via repeated study.

“…At a functional level, this back projection likely amplifies neural signalling elicited by a specific face and enhances processing of the facial percept. This may manifest in a number of ways, including increased attention and greater recall (Baldauf & Desimone, ; Hasinski & Sederberg, ).…”

Objectives: Social anxiety disorder involves biased cognition and altered neural responses to social stimuli. This study further assesses the precise ways in which neural activation associated with perceptual processing of faces differs in socially anxious and non-anxious individuals. Method: Functional magnetic resonance imaging data were acquired as 90 anxious or healthy juveniles and adults performed a peer feedback task. Psychophysiological functional connectivity analysis was performed on all participants using a seed placed in the right fusiform face area (rFFA). Results: Social anxiety was associated with enhanced rFFA coupling in several areas of ventral visual stream when viewing feedback from peers previously rejected by participants; healthy participants demonstrated the opposite pattern. Moreover, anxious juveniles had greater positive rFFA coupling with right inferior temporal gyrus during feedback from rejected peers; other groups showed the opposite pattern. Finally, anxious juveniles had greater positive rFFA coupling with pregenual anterior cingulate cortex during negative peer feedback; other groups displayed the opposite pattern. Conclusions: Anxious individuals, and juveniles in particular, may dedicate more neural resources to stimuli associated with potentially negative, relative to positive, social outcomes; non-anxious individuals may do the opposite.
