Success of Hand Movement Imagination Depends on Personality Traits, Brain Asymmetry, and Degree of Handedness

This study investigates how personality traits, brain asymmetry, and handedness influence the success of controlling brain-computer interfaces (BCIs) using motor imagery. The research found that certain personality traits are associated with better BCI control during the imagination of left or right hand movements. These traits differ depending on whether the individual is a 'pure' right-hander or a latent left-hander. The study also explored the subjective complexity of real and imagined movements, finding correlations with the accuracy of brain state recognition and highlighting the role of interhemispheric differences in motor control.

• 1
  Reserved, practical, skeptical, and less sociable individuals show higher success in brain state recognition during left hand movement imagination.
• 2
  Extraversion, liveliness, and dominance are significant for right hand movement imagination in 'pure' right-handers, while sensitivity is important for latent left-handers.
• 3
  Subjective complexity of real left hand and imagined right hand movements correlates with the success of brain state recognition, depending on the level of handedness.
