Discrimination of mnemonic similarity is associated with short-term and long-term memory precision.

Remembering specific memories with precision relies on the differentiation of similar memory contents - a process commonly referred to as pattern separation and behaviorally operationalized as lure discrimination in the mnemonic similarity task. Although pattern separation is typically investigated in the context of long-term memory (LTM), recent research extends these findings to short-term memory (STM) within a mixture model framework, emphasizing the distinction between memory quality and quantity. According to this framework, pattern separation is associated with memory precision across STM and LTM, regardless of the overall memory likelihood.

Examining the consistency of continuous affect annotations and psychophysiological measures in response to emotional videos.

Despite the growing necessity of understanding the dynamics of emotion by naturalistic stimuli, averaging time-locked responses seems insufficient to capture emotional experiences that change over time. Intersubject correlation (ISC) has been implemented to examine dynamic emotional experiences by quantifying the consistency of responses across individuals. While previous research has shown that enhanced psychophysiological ISC can capture dynamic emotional experiences in response to long-lasting videos that evoke dimensional emotions, it is not yet fully understood how psychophysiological consistency varies during videos that elicit distinct emotions, such as fear.
