Stress has a significant detrimental effect on memory
formation. If any strong emotion is present during an event, the neurons active
during this event produce strong connections with each other. When the event is
recalled, the neurons will more easily and speedily make the same connections
(which can be disastrous for those suffering from PTSD or drug addiction
withdrawal). These memories also tend to be warped or focused on extreme
details rather than the greater context of the scene—another way self-awareness
can promote healthy memories.
Get plenty of sleep! Neuroimaging studies have shown
activation patterns in the sleeping brain which mirror those recorded during
the learning of tasks from the previous day, suggesting that new memories may
be solidified through such rehearsal. Coupled with a nightly recollection of
the day prior, or even a dream journal, sleep can be a very powerful tool for
managing memories.
Meditation, a form of mental training to focus attention,
also seems to increase the control over brain resource distribution, improving
both attention and discipline. The changes are potentially long-lasting, as
meditation may have the ability to strengthen neuronal circuits as selective
attentional processes improve.
Playing music also improves various aspects of memory through
abstract connections in the brain between acoustic, semantic, and
language-processing regions. Research shows that children who participated in
one year of instrumental musical training showed improved verbal memory,
whereas no such improvement was shown in children who discontinued musical
training.
