Subliminal mortality salience does not increase physical strength output in double-blind randomized controlled trial

Area of Science:

• Psychology
• Sport Science
• Social Psychology

Background:

• The morality salience paradigm explores how awareness of death influences psychological processes.
• Terror management theory suggests people defend against death anxiety through cultural worldviews and self-esteem.
• Previous research has explored the impact of mortality salience on various behaviors and cognitive functions.

Purpose of the Study:

• To investigate whether subliminal death stimuli enhance physical strength in athletes.
• To examine the moderating roles of mindfulness and self-esteem instability in terror management.
• To explore the relationship between mortality salience, physical performance, and psychological moderators.

Main Methods:

• A sample of 160 undergraduate sports students participated.
• Participants completed a subliminal word decision task (death vs. pain stimuli).
• Grip strength was measured using a hand dynamometer before and after the task.

Main Results:

• Linear mixed models did not support the mortality salience hypothesis regarding physical strength.
• Mindfulness and self-esteem instability did not significantly influence terror management.
• No significant effect of subliminal death stimuli on grip strength was found.

Conclusions:

• Subliminal mortality salience does not appear to directly enhance physical strength in this population.
• Mindfulness and self-esteem instability may not be significant moderators of terror management in the context of physical performance.
• Further research is needed to clarify the complex interplay between mortality salience, athletic performance, and psychological factors.
