This study shows that exceeding working memory capacity reduces asymmetric associations between items, which are precursors to chunking and learning.

The paper investigates the temporal dynamics of memory retrieval by comparing perceptual and conceptual information processing during object perception and memory recall, finding reversed information flow during recall.

Speed of time-compressed forward replay flexibly changes in human episodic memory

The paper shows that human episodic memory replay involves temporally compressed forward replay of sub-events, with flexible skipping across transitions.

The paper investigates age-related differences in memory benefits from semantic congruency using fMRI data from children and adults.

On the relationship between the rate of learning and retrieval-induced forgetting

This study investigates how the rate of learning affects retrieval-induced forgetting, finding that increased learning rates reduce or eliminate the adverse memory effect.

The congruence effect is impaired in healthy aging: a relationship to event-related potentials and theta-alpha oscillations

This study shows that the congruence effect on memory declines with age, linked to changes in ERP and theta-alpha oscillations.

The relationship between age, neural differentiation, and memory performance

The paper examines the relationship between neural differentiation, age, and episodic memory performance, finding that reduced differentiation in the parahippocampal place area (PPA) correlates with memory performance independently of age.

Specifying a causal role for angular gyrus in autobiographical memory

This study uses transcranial magnetic stimulation to show that angular gyrus selectively impairs free recall of autobiographical memories but not cued recall or word pair memories.

Locally distributed abstraction of temporal distance in human parietal cortex

The paper identifies a multivoxel representation of temporal distances in the human parietal cortex using fMRI and representational similarity analysis, showing its vulnerability to disruption and its role in episodic memory retrieval.

Modulation of naturalistic maladaptive memories using behavioural and pharmacological reconsolidation-interfering strategies: A systematic review and meta-analysis of clinical and ‘sub-clinical’ studies

This paper reviews and meta-analyzes studies on modulating maladaptive memories through reconsolidation strategies in substance use and anxiety/trauma disorders, finding mixed but generally positive effects.

Reductions in Retrieval Competition Predict the Benefit of Repeated Testing

This study shows that reduced retrieval competition during practice predicts better long-term memory retention from repeated testing.

Decomposing parietal memory reactivation to predict consequences of remembering

The paper shows that different types of parietal reactivation during memory retrieval predict distinct memory outcomes: category-level reactivation increases false alarms, while item-level reactivation improves correct rejections.

Parietal representations of stimulus features are amplified during memory retrieval and flexibly aligned with top-down goals

The paper shows that lateral parietal cortex (LPC) amplifies stimulus feature information during memory retrieval compared to perception, with dorsal LPC reflecting top-down goals and ventral LPC being goal-independent.

Dynamics of brain activity reveal a unitary recognition signal

The paper uses EEG data to show that recognition memory is based on a single integrated evidence signal rather than separate familiarity and recollection signals.

Quantifying metacognitive thresholds using signal-detection theory

This paper introduces a new behavioural measure of confidence, m-distance, that is invariant to decision bias and task performance, and demonstrates its robustness through computational simulations.

Non-monotonic recruitment of ventromedial prefrontal cortex during remote memory recall

The paper investigates the time-course of ventromedial prefrontal cortex (vmPFC) recruitment during remote memory recall using fMRI and finds a non-monotonic pattern of engagement over time.

Failure to reactivate salient episodic information during indirect and direct tests of memory retrieval

This study failed to replicate findings of unconscious reactivation during memory retrieval and found test items indistinguishable by encoding context.

Neurofeedback helps to reveal a relationship between context reinstatement and memory retrieval

The paper uses neurofeedback to show that context reinstatement improves recall of related memories while impairing recall of unrelated ones, and that this relationship disappears without neurofeedback.

Pre-stimulus oscillatory activity predicts successful episodic encoding for both young and older adults

This study shows that pre-stimulus oscillatory EEG activity predicts episodic memory accuracy in both young and older adults, with age-related changes in specific frequency bands.

Decoding Selective Attention to Context Memory: An Aging Study

This study uses MVPA on EEG to decode selective attention during encoding and links attentional shifts to memory accuracy and hyper-binding in young and older adults.

Causal evidence for mnemonic metacognition in human precuneus

This study uses transcranial magnetic stimulation to show that the precuneus is selectively involved in mnemonic metacognition, not perceptual discrimination.

This study shows that pupil dilation during encoding predicts long-term memory retention of visual and auditory stimuli, highlighting the role of arousal in memory formation.

Neural Overlap In Item Representations Across Episodes Impairs Context Memory

The paper investigates how neural overlap in item representations across episodes affects context memory, finding that greater similarity in neural patterns leads to worse source memory for initial contexts.

Post-reactivation new learning impairs and updates human episodic memory through dissociable processes

This study shows that post-reactivation new learning impairs episodic memory without disrupting reconsolidation, involving distinct processes for integration and impairment.
