Affective music during episodic memory recollection modulates subsequent false emotional memory traces: an fMRI study - Cognitive, Affective, & Behavioral Neuroscience

Music is a powerful medium that influences our emotions and memories. Neuroscience research has demonstrated music’s ability to engage brain regions associated with emotion, reward, motivation, and autobiographical memory. While music's role in modulating emotions has been explored extensively, our study investigates whether music can alter the emotional content of memories. Building on the theory that memories can be updated upon retrieval, we tested whether introducing emotional music during memory recollection might introduce false emotional elements into the original memory trace. We developed a 3-day episodic memory task with separate encoding, recollection, and retrieval phases. Our primary hypothesis was that emotional music played during memory recollection would increase the likelihood of introducing novel emotional components into the original memory. Behavioral findings revealed two key outcomes: 1) participants exposed to music during memory recollection were more likely to incorporate novel emotional components congruent with the paired music valence, and 2) memories retrieved 1 day later exhibited a stronger emotional tone than the original memory, congruent with the valence of the music paired during the previous day’s recollection. Furthermore, fMRI results revealed altered neural engagement during story recollection with music, including the amygdala, anterior hippocampus, and inferior parietal lobule. Enhanced connectivity between the amygdala and other brain regions, including the frontal and visual cortex, was observed during recollection with music, potentially contributing to more emotionally charged story reconstructions. These findings illuminate the interplay between music, emotion, and memory, offering insights into the consequences of infusing emotional music into memory recollection processes.

Is N-Hacking Ever OK? The consequences of collecting more data in pursuit of statistical significance

When an experiment comes to an end, it can be tempting to collect more data if a trend is observed that is “not quite significant”. This Essay uses simulations to investigate if this type of sample augmentation can ever be an acceptable practice and, if so, when it could be beneficial.
