Memory loss is a sign of normal and pathological aging and represents an urgent public health problem for the global "grey" population, as memory loss is likely to be one of the earliest manifestations of Alzheimer's disease.
studies have shown that physical and cognitive activity cushions memory loss.
, although positive emotions play an important role in every aspect of our lives, little is known about the relationship between emotions and memory.
recently, Psychological Science magazine published online a study by the Claudia M. Haase team at Northwestern University entitled "Positive Affect Is Associated With Less Memory Decline: Evidence From a 9-Year Longitudinal Study."
a nine-year longitudinal study of middle-aged and older people across the United States that examined the relationship between positive emotions and memory.
researchers analyzed a study conducted in 1995-1996 (time 1), 2004-2006 (time 2) and 2013-2014 (time 3) A national study of the situation of middle-aged Americans (MIDUS) included 991 middle-aged Americans and older people who spanned a nine-year gap between time 2 and 3 to record a series of positive emotions they experienced and conducted a scale test.
memory test includes recalling words immediately after a speech and recalling them again 15 minutes later.
researchers analyzed the relationship between positive emotions and memory loss, including age, gender, education level, depression, negative emotions, and found that memory declined with age.
Regression analysis showed that after correcting age, gender, education, depression, and negative effects, positive emotions for more than 9 years were associated with less memory loss, meaning that people with higher positive moods had less memory loss than those with lower positive emotions.
with age, many adults are at risk of cognitive decline.
study found that positive effects in middle-aged and older people were associated with memory loss with age, and that people with higher positive emotions had less memory loss.
"smile, ten years less," the study re-emphasized the importance of mindset, which helps to slow memory decline.
