Research shows that emotions can have an effect on your memory. People who are in a positive mood are more likely to remember information presented to them, whereas people who are in a negative mood (i.e. sad or angry) are less likely to remember the information that is presented to them (Levine & Burgess, 1997).
How does mood affect the brain?
Many studies have shown that your mood can influence perception, motivation, decision-making, social interactions, and even more basic cognitive processes like memory and attention.
Is a negative memory?
Overgeneral negative memory means that, when prompted to recall prior negative experiences, the individual may remember their feelings of distress at the time but be unable to recall specific details of the event.
