How does social distancing during COVID-19 affect negative moods and memory?

Area of Science:

• Psychology
• Cognitive Science
• Public Health

Background:

• Social distancing is a primary strategy to mitigate COVID-19 transmission.
• The psychological effects of social distancing, especially on memory, remain unclear.
• Understanding these effects is crucial for public health strategies.

Purpose of the Study:

• To investigate the impact of social distancing duration on negative mood and memory.
• To explore the relationship between time spent in isolation and psychological outcomes.

Main Methods:

• Assessed the correlation between the duration of social distancing and mood states.
• Evaluated memory performance and the occurrence of memory errors.
• Utilized statistical analysis to identify U-shaped functions and mediation effects.

Main Results:

• Both negative mood and memory errors followed a U-shaped function with social distancing duration.
• Initially, longer social distancing reduced negative moods and memory errors.
• After approximately 30 days, prolonged social distancing increased negative moods and memory errors, with loneliness mediating memory deficits.

Conclusions:

• Short-term social distancing may offer psychological and memory benefits.
• Extended social distancing (over 30 days) adversely affects mood and memory performance.
• Loneliness is a key factor linking prolonged isolation to memory impairment.
