The research suggests that clinicians should consider the context of recovered memories to effectively treat patients.
A recent study found that when people are told false information about an event shortly after witnessing it, they become less likely to remember the actual details. However, forcing them to recall what they witnessed shortly afterwards improves their ability to learn and retain false information.
A computational model suggests that newborn brain cells add a unique time-related code to memories formed around the same time. This allows for recall of events from a certain period and connects independent events that occurred during the same hyperactive period, explaining why memories can be triggered by specific details.
A new study by Nicole Votolato Montgomery and H. Rao Unnava found that consumers tend to favor vacations with improved outcomes over those with worsened outcomes when evaluated immediately, but reverse preferences emerge after a delay.

A study by Duke University Medical Center found that older adults use their brains differently when it comes to storing memories associated with negative emotions. Older adults have less connectivity between emotion-generating and memory regions, but stronger connections with the frontal cortex, which controls lower-order brain functions.
Researchers found that older adults remember fewer negative events than younger counterparts due to differences in brain activity. The study suggests that seniors' brains use thinking rather than feeling processes to store emotional memories, which may improve understanding of mental health issues like depression and anxiety.

A recent study by researchers at UC San Diego found that proper spacing of lessons can dramatically enhance learning. The study, which involved over 1,000 subjects, revealed that larger gaps between study sessions result in better recall of facts. This contradicts the common practice of cramming, which is not effective in the long haul.

Researchers found that paper wasps remember individuals for at least a week, even after meeting multiple other wasps. This ability is based on memories of past social interactions rather than simple rules, suggesting that these insects have a strong, long-term memory and bases its behavior on what it remembers.

The study confirms that spontaneous memories arise with activity of the same neurons that were recorded as they fired when the memory was first being made.
A study found that sleep plays a key role in preserving emotional memories, strengthening the memory's emotional core while diminishing neutral background details. This process enables the brain to selectively preserve only the most salient information, leading to vivid recall of emotional events.
Researchers at the University of Cambridge have discovered that disrupting or erasing memories associated with drug use during recall can prevent relapse in recovering drug abusers. By blocking a brain chemical receptor important to learning and memory, scientists reduced drug-seeking behaviors in rats for up to four weeks.
Researchers have shown that our visual working memory can be shared out across the whole image, with more memory allocated for objects of interest and less for background detail. This means that we don't just remember every detail, but focus on the broad gist and specific details.
Research suggests that alliteration improves memory for both content and thematic aspects of literature. Participants who read works with similar alliterative sounds performed better in memory recall than those who read without or with different sounds.
The US military employs 'Indian Country' metaphors to describe hostile territories in war zones, drawing on a presumed collective memory of past battles. This metaphor reframes Native American histories and struggles in light of contemporary terrorism.
Children can start using mental chunking techniques from as early as 14 months old, remembering more items at a time. By grouping familiar objects together and using spatial cues, young children can expand their memory capacity.
Researchers found that people tend to underestimate the intensity of their mixed feelings when recalling them. This effect is more pronounced over time and affects individuals from different ethnic backgrounds differently.
Octopus brains utilize activity-dependent long-term synaptic potentiation (LTP) to store and recall memories, with findings suggesting a segregation of short and long-term memory systems. This process is comparable to that discovered in vertebrate brains, yet operates differently due to the octopus's unique brain anatomy.
Researchers found that honeybees use their right and left antennae to store different types of memories. Short-term memory is linked to the right antenna, while long-term learning relies on the left antenna. This lateralization may aid bees in learning new odours without interference from existing memories.
Researchers found that people tend to focus on one win among hundreds of losses, justifying further gambling. A 'silver lining' effect makes losers remember positive experiences more easily when losses are far apart.
