The age-related positivity effect: forgetting the negative and/or remembering the positive? An inter-task study

Area of Science:

• Cognitive Psychology
• Neuroscience of Aging
• Memory Studies

Background:

• Research indicates older adults exhibit an age-related positivity effect, recalling positive information better than negative.
• The underlying mechanisms of this effect—whether enhanced positive recall or reduced negative recall—remain unclear.

Purpose of the Study:

• To investigate the specific cognitive mechanisms driving the age-related positivity effect in memory.
• To differentiate between enhanced positive memory and reduced negative memory in older adults.

Main Methods:

• Employed an emotional word memory paradigm with immediate free recall, recognition, and delayed free recall tasks.
• Utilized 36 French low-arousal words (positive, neutral, negative) and 36 new words for recognition.
• Compared memory performance between 45 young adults (mean age 20.0) and 45 older adults (mean age 69.2).

Main Results:

• The age-related positivity effect was linked to a decrease in negativity preference (negative vs. neutral words) in older adults.
• Younger adults recalled more negative than neutral words; older adults showed no difference in recall.
• No age-related positivity effect was observed in the recognition task.

Conclusions:

• Older adults appear to disengage from processing negative words, which require significant cognitive resources.
• A low negativity preference correlates with well-maintained memory abilities in older adults.
• Findings align with socio-emotional selectivity theory, suggesting a shift in processing priorities with age.
