This study found that caffeine consumption after learning did not improve face recognition memory consolidation but increased false alarms, suggesting it may impair detailed discrimination.

Retrieval practice prevents stress-induced inference impairment and preserves rapid bridge-related memory reactivation

This study shows that retrieval practice reduces stress-induced impairment in memory inference by preserving the reactivation of a bridge element during inference.

Investigation of the neural effects of memory training to reduce false memories in older adults: Univariate and multivariate analyses

This study investigates how memory training reduces false memories in older adults using neural activity and discriminability analyses.

Method of loci training yields unique prefrontal representations that support effective memory encoding

The paper investigates how memory training using the method of loci affects neural representations in memory athletes and novices, finding distinct prefrontal cortex patterns linked to better memory performance.

Computational models suggest that human memory judgments exhibit interference due to the use of distributed representations

The paper uses computational models to show that human memory performance is better explained by distributed representations in the neocortex rather than hippocampal pattern separation.

Neural codes track prior events in a narrative and predict subsequent memory for details

The paper investigates how context-dependent temporal structures are represented in the brain during narrative processing and finds that these representations predict memory for details.

Proactive and reactive construction of memory-based preferences

The paper shows that the brain uses proactive and reactive memory strategies for decision-making, with proactive being more efficient but reactive used when options have more memory associations.

When Group Means Fail: Can One Size Fit All?

The paper examines whether a group-based cognitive process model applies to individuals, finding that the serial exhaustive search model fits only some participants.

The relationship between neural differentiation and exploratory eye movements in healthy young and older adults

This study examines how age affects neural selectivity and eye movements during scene and object processing, finding age-related differences in their relationship.

Benefits of spaced learning are predicted by re-encoding of past experience in ventromedial prefrontal cortex

This study shows spaced learning enhances neural representations in ventromedial prefrontal cortex, which correlates with improved memory performance.

Effects of age in the strategic control of recollected content as reflected by modulation of scene reinstatement

This study investigates age-related differences in retrieval gating by examining scene reinstatement in young and older adults during memory tasks.

Independent regulation of memory and emotion by selective retrieval

The paper shows that selective retrieval of a memory reduces both the mnemonic content and emotional impact of competing memories through distinct neural mechanisms.

This study examines how neural signatures of memory retrieval, measured via EEG, are influenced by memory quality and specific event features.

Evidence for a reactionary account of retrieval state initiation

The paper investigates when the retrieval state is initiated, finding it occurs reactively after stimulus onset rather than preparatorily before.

Concurrent representations of reinstated and transformed memories and their modulation by reward

This study shows that memory retrieval involves both reinstating original neural patterns and activating transformed, generalized representations, with reward enhancing transformation in the anterior hippocampus.

Confidence and insight into working memories are shaped by attention and recent performance

The paper investigates how attention and performance feedback influence confidence and insight in working memory, showing attention improves confidence judgments and feedback helps update beliefs over time.
