Summary: This study identifies brain states using scalp EEG from male and female human subjects and shows the extent to which temporal overlap promotes interference and induces retrieval. Greater temporal overlap leads to impaired memory for the past event selectively when the top-down goal is to encode the present event. Additionally, greater temporal overlap leads to automatic retrieval of a past event, independent of top-down goals. These findings provide insight into the role of temporal overlap on interference and memory formation.

Summary: This study investigates whether the contextual features specifying the encoding episodes are incidentally reinstated during competitive memory retrieval. The results show proactive interference and the reinstatement of competitor context during competitive retrieval, and the resolution of interference is associated with the subsequent reinstatement of the target context.

Summary: Research showing that dolphins can answer unexpected questions after encoding seemingly unimportant information challenges the long-held belief that complex cognition is unique to humans.

Summary: This study reveals how temporal compression during memory recall is manifested in the brain and can predict encoding-to-recall transformations. These findings enhance our understanding of how human memory is expressed.

Summary: This study used an eye-tracking task to investigate whether there are differences in memory-specific viewing patterns towards scenes between autistic and non-autistic individuals. The results showed no significant differences in viewing during the encoding process, suggesting comparable processing of scene details between the two groups. However, autistic individuals exhibited differences in explicit recognition accuracy for scenes with relational changes.

Summary: Episodic memories contain both simple and complex features, which are successfully encoded and recognized in different temporal orders, with simple features being processed earlier than complex features. These processes are influenced by attention and remain consistent across different age groups.

Summary: Recent evidence suggests that the dynamic unfolding of events is temporally compressed in memory representations, but the exact nature of this compression mechanism remains unclear. This study tested two possible mechanisms, the discontinuity hypothesis and the acceleration hypothesis, to explain this compression. The results support the discontinuity hypothesis, indicating that episodic memory omits redundant and predictable time segments while selectively retaining more informative segments to represent event unfolding.

Summary: Converging evidence from studies of human and nonhuman animals suggests that the hippocampus contributes to sequence learning by using temporal context to bind sequentially occurring items. This study tested the prediction that individual differences in fornix microstructure predict sequence memory. The results showed that greater fornix microstructural complexity is associated with better sequence memory, highlighting the importance of the fornix in aiding memory for objects within a temporal context.

Summary: This paper proposes a cognitive model called STEM-ADL, which encodes event sequences to predict the type and starting time of daily self-care activities. Experimental results demonstrate that STEM-ADL outperforms other models and is suitable for real-life healthcare applications.

Summary: Memories are believed to undergo a time-dependent system consolidation, during which hippocampal activity decreases and neocortical activity increases. However, noradrenergic arousal after encoding can reverse this process and maintain the vividness of memories over time.

Summary: Memory involves encoding, consolidating, and retrieving information. Targeted memory reactivation is an experimental method that reactivates sensory components to enhance memory retrieval. In this study, participants were presented with everyday objects, some of which were tagged with sounds. Unusual objects and sounds were created as "oddballs". During a reactivation phase, participants listened to a replay of normal and oddball sounds. The results showed that participants had better memory for oddball objects, especially when their sounds were reactivated.

Summary: Mental time travel to personal past and future events share cognitive and neural similarities, with temporal distance modulating the recruitment of episodic processing and monitoring processes in different ways for past and future event simulations. These findings suggest a greater role of semantic memory in episodic mental time travel to farther temporal distances.

Summary: When forming a memory of a time-based experience, we can use our prior knowledge to predict what will happen. Researchers developed a new method to investigate how the development of a complex pattern impacts predictive processes and sequential memory. Participants learned a new board game and their ability to remember sequences improved as their pattern knowledge developed. Eye tracking revealed that expert players showed more predictive eye movements during encoding, which led to better memory performance. This study highlights the role of prediction in improving episodic memory through pattern knowledge.

Summary: The study demonstrates that temporal properties of visual events are encoded alongside spatial properties, even when time and space are not task-relevant. Removing spatial or temporal information during retrieval incurs costs, indicating memory relies on the initial spatial and temporal context of items. Spatial and temporal inter-item spacings influence the weighting of spatial and temporal information, facilitating individuation and access to representations.
