Subliminal Priming Effects on Motor and Cognitive Performance: Pilot Evidence With Implications for...

Area of Science:

• Neuroscience
• Motor Control
• Cognitive Psychology

Background:

• Subliminal stimuli are presented below conscious awareness.
• Investigating subliminal priming's impact on human performance is crucial for understanding subconscious processing.
• Gender differences in motor and cognitive functions are well-documented.

Purpose of the Study:

• To determine if visual, auditory, or word-based subliminal priming affects motor and cognitive performance in young adults.
• To explore potential gender-specific variations in these effects.

Main Methods:

• 30 healthy adults participated in a single-blind, randomized study.
• Subliminal stimuli (50 ms) were presented across three modalities: visual, auditory, and word-based.
• Motor performance was assessed via reaction time (RT-R, RT-L), 10-Meter Walk Test (10MWT), and Timed Up and Go (TUG). Cognitive function was measured using the Trail Making Test (TMT).

Main Results:

• No significant effects were found for reaction time on the dominant side (RT-R), comfortable walking speed, TUG, or TMT.
• A significant main effect of priming modality was observed for maximal 10MWT speed (p = 0.044).
• Significant interactions between priming modality and gender were found for maximal 10MWT speed (p = 0.044) and reaction time on the non-dominant side (RT-L) (p = 0.026), indicating gender-specific responses.

Conclusions:

• Subliminal priming demonstrated modest, gender-dependent effects on maximal walking speed and non-dominant hand reaction time.
• Preliminary results suggest that complex motor tasks may exhibit selective sensitivity to subliminal cues.
• Further research with larger cohorts and clinical populations is recommended to validate these findings.
