A substantial part of age-related episodic memory decline has been attributed to the decreasing ability of older adults to encode and retrieve associations among simultaneously processed information units from long-term memory. In addition, this ability seems to share unique variance with reasoning. In this study, we therefore examined whether process-based training of the ability to learn and ...

The last decade has seen dramatic technological and conceptual changes in research on episodic memory and the brain. New technologies, and increased use of more naturalistic observations, have enabled investigators to delve deeply into the structures that mediate episodic memory, particularly the hippocampus, and to track functional and structural interactions among brain regions that support i...

Verbal episodic memory deficits, a well-established feature of the schizophrenia spectrum, have also been found in individuals with schizotypal personality disorder (SPD), although visual-spatial episodic memory has proven harder to examine. To address this, we administered the Visual Object Learning Test (VOLT), a measure of visual-spatial learning and memory, as well as the California Verbal ...

Embodiment has highlighted the importance of sensory-motor components in cognition. Perception and memory are thus very tightly bound together, and episodic and semantic memories should rely on the same grounded memory traces. Reduced perception should then directly reduce the ability to encode and retrieve an episodic memory, as in normal aging. Multimodal integration deficits, as in Alzheimer...

We examined emotional memory in patient SP, a 54-yearold woman with bilateral damage to the amygdala. Consistent with previous case studies, SP showed deficits on tests of fear conditioning and recognition memory for arousing stimuli. SP's performance on several emotional episodic memory tasks was examined. We found that bilateral damage to the amygdala only leads to deficits on a subset of emo...

Reactivation of long-term memory can render the memory item temporarily labile, offering an opportunity to modify it via behavioral or pharmacological intervention. Declarative memory reactivation is accompanied by a metamemory ability to subjectively assess the knowledge available concerning the target item (Feeling of knowing, FOK). We set out to examine whether FOK can predict the extent of ...

A new study in which rats had to discriminate odors according to whether they were novel for a particular environmental context has found that they can accurately discriminate a large number of odors and multiple context transitions, suggesting that they are able to form and remember multiple episodic memories.

Representations of unique events from one's past constitute the content of episodic memories. A number of studies with non-human animals have revealed that animals remember specific episodes from their past (referred to as episodic-like memory). The development of animal models of memory holds enormous potential for gaining insight into the biological bases of human memory. Specifically, given ...

Recent evidence indicates that the processing of a stimulus can be influenced by preceding patterns of brain activity. Here we examine whether prestimulus oscillatory brain activity can influence the ability to retrieve episodic memories. Neural activity in the theta-frequency band (4-8 Hz) was enhanced before presentation of test items which elicited accurate recollection of contextual details...

In a memory survey, adult respondents recalled, dated, and described two earliest positive and negative memories that they were highly confident were memories. They then answered a series of questions that focused on memory details such as clothing, duration, weather, and so on. Few differences were found between positive and negative memories, which on average had 4/5 details and dated to the ...
