It is well established that the formation of memories for life's experiences-episodic memory-is influenced by how we attend to those experiences, yet the neural mechanisms by which attention shapes episodic encoding are still unclear. We investigated how top-down and bottom-up attention contribute to memory encoding of visual objects in humans by m...

... attention seeds show connectivity that differs according to encoding success or failure. A, Regions whose connectivity with left mIPS/SPL (green sphere, peak mIPS/SPL coordinates of the top-down attention contrast are illustrated in Fig. 2) was stronger during preparatory periods of trials resulting in objects being remembered versus forgotten (positive subsequent connectivity effects; warm colors); regions showing the opposite effect, or stronger connectivity with left mIPS/SPL during preparatory periods leading to forgotten versus remembered objects (negative subsequent connectivity effects) are displayed in cool colors [note that the small cluster in dorsal AnG (coordinates 39, 57, 33) is in fact spatially contiguous with the large ventral AnG cluster that has been surface rendered dorsally (for details, see Table 6)]. Scatter plot illustrates that individual differences in the strength of the positive subsequent connectivity effect in LO/fusiform during encoding correlates with across-subject differences in later memory performance, such that the stronger the mIPS/SPL-LO/fusiform connectivity, the superior the later memory performance. ...

We found no regions that showed positive sub- sequent memory connectivity effects with the right TPJ seed and only a few that did so with the left TPJ seed (Table 6). By contrast, the TPJ seeds showed robust negative subsequent memory con- nectivity effects with a broad set of regions (Table 6). ...

Visual working memory (VWM) is traditionally assumed to be immune to proactive interference (PI). However, in a recent study (Endress & Potter, 2014), performance in a visual memory task was superior when all items were unique and hence interference from previous trials was impossible, compared to a standard condition in which a limited set of repe...
Number order processing is thought to be characterised by a reverse distance effect whereby consecutive sequences (e.g., 1–2–3) are processed faster than non-consecutive sequences (e.g., 1–3–5). However, there is accumulating evidence that the reverse distance effect is not consistently observed. In this context, the present study investigated whet...

In research with young adults, there is substantial evidence to support that attentional control is important for memory (e.g., Aly & Turk-Browne, 2016a, 2016bNoonan et al., 2016;Uncapher et al., 2011;Uncapher & Rugg, 2005).

... The present focus on factors driving age-related declines in neural selectivity revealed that topdown attention during encoding (a) predicts subsequent memory (28,30,65,92), (b) modulates neural selectivity (17,22,26), (c) does not vary with plasma or CSF biomarkers of preclinical AD, and (d) partially accounts for age-independent and age-related variability in memory through its impact on neural selectivity. Controlling for age, CU older adults with greater memory-related neural activity in the DAN demonstrated higher neural selectivity during subsequently remembered events, with the DAN SME being the top predictor of variance in neural selectivity. ...
Human aging affects the ability to remember new experiences, in part, because of altered neural function during memory formation. One potential contributor to age-related memory decline is diminished neural selectivity -- i.e., a decline in the differential response of cortical regions to preferred vs. non-preferred stimuli during event perception -- yet the factors driving variability in neural selectivity with age remain unclear. We examined the impact of top-down attention and preclinical Alzheimer's disease (AD) pathology on neural selectivity during memory encoding in 156 cognitively unimpaired older participants who underwent fMRI while performing a word-face and word-scene associative memory task. Neural selectivity in face- and place-selective cortical regions was greater during events that were later remembered compared to forgotten. Critically, neural selectivity during learning positively scaled with memory-related variability in top-down attention, whereas selectivity negatively related to early AD pathology, evidenced by elevated plasma pTau181. Path analysis revealed that neural selectivity at encoding mediated the effects of age, top-down attention, and pTau181 on associative memory. Collectively, these data reveal multiple pathways that contribute to memory differences among older adults -- AD-independent reductions in top-down attention and AD-related pathology alter the precision of cortical representations of events during experience, with consequences for remembering.
... Previous research in cognitive psychology reveals a link between attention and memory (Craik, 2002;Sherman and Turk-Browne, 2022;Uncapher et al., 2011). This attention-retention link is very compatible with advertising insights and motivates advertisers to achieve optimal exposure and wide reach, increasing the likelihood of advertisement success (McGuire, 2001;Rossiter and Bellman, 2005). ...
In contemporary urban environments, advertisements are ubiquitous, capturing the attention of individuals navigating through cityscapes. This study simulates this situation by using VR as an advertising research tool and combining it with eye-tracking to rigorously assess attention to and retention of visual advertisements. Specifically, participants drove through a virtual city with 40 AI-generated, experimentally manipulated, and randomly assigned advertisements (20 commercial, 20 health) distributed throughout. Our results confirm theoretical predictions about the link between exposure, visual attention, and incidental memory. Specifically, we found that attended ads are likely to be recalled and recognized, and concurrent task demands (counting sales signs) decreased visual attention and subsequent recall and recognition of the ads. Finally, we identify the influence of ad placement in the city as a very important but previously hard-to-study factor influencing advertising effects. This paradigm offers great flexibility for biometric advertising research and can be adapted to varying contexts, including highways, airports, and subway stations, and theoretically manipulate other variables. Moreover, considering the metaverse as a next-generation advertising environment, our work demonstrates how causal mechanisms can be identified in ways that are of equally high interest to both theoretical as well as applied advertising research.
... Our findings advance the understanding of neural mechanisms underlying the attention-to-memory model, which posits that attention plays a critical role in the encoding and retrieval of memories Uncapher and Wagner 2009;Uncapher et al. 2011;Cabeza et al. 2012;Gilmore et al. 2015). According to this model, attention focuses cognitive resources on relevant information, enhancing the encoding of information into memory and facilitating its subsequent retrieval. ...
Hippocampus-parietal cortex circuits are thought to play a crucial role in memory and attention, but their neural basis remains poorly understood. We employed intracranial electroencephalography (iEEG) to investigate the neurophysiological underpinning of these circuits across three memory tasks spanning verbal and spatial domains. We uncovered a consistent pattern of higher causal directed connectivity from the hippocampus to both lateral parietal cortex (supramarginal and angular gyrus) and medial parietal cortex (posterior cingulate cortex) in the delta–theta band during memory encoding and recall. This connectivity was independent of activation or suppression states in the hippocampus or parietal cortex. Crucially, directed connectivity from the supramarginal gyrus to the hippocampus was enhanced in participants with higher memory recall, highlighting its behavioral significance. Our findings align with the attention-to-memory model, which posits that attention directs cognitive resources toward pertinent information during memory formation. The robustness of these results was demonstrated through Bayesian replication analysis of the memory encoding and recall periods across the three tasks. Our study sheds light on the neural basis of casual signaling within hippocampus–parietal circuits, broadening our understanding of their critical roles in human cognition.
... Namely, T6, i.e., localized posterior temporal, could be in junction with semantic processing [77]. Statistically significant impact on beta processing obtained for RCPR, but not separately in C4 or P4 electrode, indicates that this whole brain activity is in junction with memory integration of different stimuli to long-term mental lexicon [90]. From this point, electrode information may be beneficial for specific language processing tasks, and the ROI information, for simpler language processing tasks. ...
Introduction:
Children with specific language impairment (SLI) have difficulties in different speech and language domains. Electrophysiological studies have documented that auditory processing in children with SLI is atypical and probably caused by delayed and abnormal auditory maturation. During the resting state, or different auditory tasks, children with SLI show low or high beta spectral power, which could be a clinical correlate for investigating brain rhythms.
Methods:
The aim of this study was to examine the electrophysiological cortical activity of the beta rhythm while listening to words and nonwords in children with SLI in comparison to typical development (TD) children. The participants were 50 children with SLI, aged 4 and 5 years, and 50 age matched TD children. The children were divided into two subgroups according to age: (1) children 4 years of age; (2) children 5 years of age.
Results:
The older group differed from the younger group in beta auditory processing, with increased values of beta spectral power in the right frontal, temporal, and parietal regions. In addition, children with SLI have higher beta spectral power than TD children in the bilateral temporal regions.
Conclusion:
Complex beta auditory activation in TD and SLI children indicates the presence of early changes in functional brain connectivity.
... In typical measures of exogenous orienting, a change occurs in the placeholder location to elicit an involuntary orienting response (such as the illumination of the locations). Conversely, in measures of endogenous orienting, a central cue is presented to prompt a voluntary orienting response toward a specific location or object (Uncapher et al., 2011;Chica et al., 2014). ...
The impact of deafness on visual attention has been widely discussed in previous research. It has been noted that deficiencies and strengths of previous research can be attributed to temporal or spatial aspects of attention, as well as variations in development and clinical characteristics. Visual attention is categorized into three networks: orienting (exogenous and endogenous), alerting (phasic and tonic), and executive control. This study aims to contribute new neuroscientific evidence supporting this hypothesis. This paper presents a systematic review of the international literature from the past 15 years focused on visual attention in the deaf population. The final review included 24 articles. The function of the orienting network is found to be enhanced in deaf adults and children, primarily observed in native signers without cochlear implants, while endogenous orienting is observed only in the context of gaze cues in children, with no differences found in adults. Results regarding alerting and executive function vary depending on clinical characteristics and paradigms used. Implications for future research on visual attention in the deaf population are discussed.

Associative memory improves during childhood, suggesting an age-related improvement in the binding mechanism responsible for linking information together. However, tasks designed to measure associative memory not only measure binding, but also place demands on attention. This makes it difficult to dissociate age-related improvements in memory from the development of attention. One way to reduce attentional demands is to test memory implicitly versus explicitly. In this study, children (8-, 10-, and 12-years-old) completed separate implicit and explicit associative memory tests. For the implicit task, children incidentally encoded pairs of objects by making an object categorization decision. At test, they completed the same task, but unbeknownst to the participants, the pairs were either intact, rearranged, or new. Next, children completed another incidental encoding phase, then an explicit test in which they indicated whether the pairs were intact, rearranged, or new. For the implicit test, all age groups had faster reaction times for intact than rearranged pairs (indicative of implicit associative memory). In the explicit test, memory performance (d’) improved with age. A separate measure of attention related to performance in both the explicit and implicit tasks. Together, these results support that attentional mechanisms are responsible for age-related improvements in associative memory.
... Imaging Neuroscience, Volume 2, 2024 studies comparing encoding under high and low attention conditions (e.g., full versus divided attention) supported this hypothesis. In these investigations, significant effects consistently emerged within diverse sensory-perceptual regions and the lateral PFC ( Kensinger et al., 2003;Uncapher & Rugg, 2005Uncapher et al., 2011), whereas they appeared more rarely within the hippocampus ( Uncapher & Rugg, 2008. The putative regional distinctions in attentional impact explain why the meta-analysis presented compelling evidence to support the attentional and semantic hypotheses while failing to substantiate the hippocampal hypothesis. ...
The subsequent memory paradigm is a fundamental tool in neuroimaging investigations of encoding processes. Although some studies have contrasted remembered trials with forgotten ones, others have focused on strongly remembered trials versus forgotten ones. This study employed a meta-analytic approach to juxtapose the effects observed in the two types of contrast. Three distinct perspectives on memory formation—semantic elaboration, attentional focus, and hippocampal processing—yield diverse hypotheses about the regions responsible for the formation of strong memories. The meta-analysis yielded evidence supporting the attentional and semantic hypotheses while failing to substantiate the hippocampal hypothesis. The discussion section integrates these varied perspectives into a coherent view, culminating in the proposal of a model called the Significance-driven and Attention-driven Memory (SAM). Several pivotal postulates underpin the SAM model. First, it establishes a link between fluctuations in the trial-to-trial encoding performance and continuous variations in sustained attention. Second, the model contends that attention exerts a potent influence on both perceptual and semantic processing, while its impact on hippocampal processing remains moderate. Lastly, the model accentuates the heightened role of the hippocampus in significance-driven encoding, as opposed to attention-driven encoding. From a specific perspective, the model’s value lies in promoting a holistic understanding of the current extensive meta-analytic results. In a more comprehensive context, the model introduces an integrated framework that synthesizes various encoding-related cognitive and neural processes into a cohesive and unified perspective.
... Previous research has implicated this region in successful encoding (Uncapher and Wagner 2009;Lee et al. 2017;Rugg and King 2018), especially for multisensory memories (Bonnici et al. 2016; Jablonowski and Rose 2022. The angular gyrus identifies cross-modal information perceived as behaviorally self-relevant (Cabeza et al. 2008;Singh-Curry and Husain 2009;Uncapher et al. 2011), and integrates it into a common egocentric framework to support re-experiencing during retrieval (Yazar et al. 2014;Bonnici et al. 2018;Bréchet et al. 2018;Humphreys et al. 2021). We add to this literature by showing that multisensory signals underpinning a stable sense of body ownership frames how the angular gyrus encodes an event. ...
How is the fundamental sense of one’s body, a basic aspect of selfhood, incorporated into memories for events? Disrupting bodily self-awareness during encoding impairs functioning of the left posterior hippocampus during retrieval, which implies weakened encoding. However, how changes in bodily self-awareness influence neural encoding is unknown. We investigated how the sense of body ownership, a core aspect of the bodily self, impacts encoding in the left posterior hippocampus and additional core memory regions including the angular gyrus. Furthermore, we assessed the degree to which memories are reinstated according to body ownership during encoding and vividness during retrieval as a measure of memory strength. We immersed participants in naturalistic scenes where events unfolded while we manipulated feelings of body ownership with a full-body-illusion during functional magnetic resonance imaging scanning. One week later, participants retrieved memories for the videos during functional magnetic resonance imaging scanning. A whole brain analysis revealed that patterns of activity in regions including the right hippocampus and angular gyrus distinguished between events encoded with strong versus weak body ownership. A planned region-of-interest analysis showed that patterns of activity in the left posterior hippocampus specifically could predict body ownership during memory encoding. Using the wider network of regions sensitive to body ownership during encoding and the left posterior hippocampus as separate regions-of-interest, we observed that patterns of activity present at encoding were reinstated more during the retrieval of events encoded with strong body ownership and high memory vividness. Our results demonstrate how the sense of physical self is bound within an event during encoding, which facilitates reactivation of a memory trace during retrieval.
... We also detected activations in the right cerebellum and the left primary motor cortex (BA4), reflecting the need for a motor response from the participants. We further found bilateral activation of the insula, the anterior IPS (Fig. 1a) and the dorso-posterior thalamus (Fig. 1b), which are implicated in error awareness and salience processing 17 , top-down regulation of attention 18 and target detection 19 , respectively. ...
... Based on this, we hypothesized that non-visual effects of light on the posterior thalamus/pulvinar could greatly modulate the activity of top-down attention-related areas, such as IPS 18 , resulting in improved alertness and attention to an ongoing auditory attentional task such as the oddball. Previous human fMRI studies identified the posterior thalamus/pulvinar as the area most consistently affected by light exposure during nonvisual cognitive tasks 7,10-12 . ...
Exposure to blue wavelength light stimulates alertness and performance by modulating a widespread set of task-dependent cortical and subcortical areas. How light affects the crosstalk between brain areas to trigger this stimulating effect is not established. Here we record the brain activity of 19 healthy young participants (24.05±2.63; 12 women) while they complete an auditory attentional task in darkness or under an active (blue-enriched) or a control (orange) light, in an ultra-high-field 7 Tesla MRI scanner. We test if light modulates the effective connectivity between an area of the posterior associative thalamus, encompassing the pulvinar, and the intraparietal sulcus (IPS), key areas in the regulation of attention. We find that only the blue-enriched light strengthens the connection from the posterior thalamus to the IPS. To the best of our knowledge, our results provide the first empirical data supporting that blue wavelength light affects ongoing non-visual cognitive activity by modulating task-dependent information flow from subcortical to cortical areas.
