The hidden mental cost of emotional rigidity in young adults

Key Points:

• A study published in Psychological Reports finds that psychological inflexibility mediates the relationship between personality traits—harm avoidance and self-directedness—and everyday cognitive difficulties such as focus, emotional regulation, and planning in young adults.
• Harm avoidance, a temperament trait linked to sensitivity to threat and anxiety, is associated with higher psychological inflexibility, which in turn predicts more frequent cognitive lapses; conversely, self-directedness, a character trait related to goal orientation, predicts lower inflexibility and fewer mental errors.
• Psychological inflexibility involves rigid avoidance of negative emotions, which consumes cognitive resources in the prefrontal cortex responsible for executive functions, leading to everyday mental slips like forgetfulness and impulsivity.
• The study, involving 501 university students aged 21, used self-report questionnaires and statistical modeling to identify psychological inflexibility as a partial mediator between personality and cognitive performance, though causality cannot be confirmed due to its cross-sectional design.
• Findings suggest that interventions targeting psychological flexibility, such as Acceptance and Commitment Therapy, may help young adults improve focus, planning, and emotional control, potentially enhancing academic performance and resilience during brain development.
