optical motion-capture system which focused on five principal components of movement: local movement, global movement, hand flux, head speed and hand distance. Local movement is a particular joint or segment of the body, like tapping just your foot on the ground. Global movement focuses on overall general body movement like your trunk and extremities. Hand flux describes movement of the hands while hand distance tracks how far or near the hands move from the trunk. Head speed tracks nodding, tilting and other movements of the head. When these 60 extreme scorers - 43 female, 17 male - were set up with 28 reflective markers to track their 3-dimension movements, they were introduced to music and encouraged to move naturally and dance. The kinematic variables that were observed and noted were instantaneous velocity (motion at a specific point in time), acceleration and the jerk of various body parts. For example, head banging to rock n’ roll music or gesturing an electric guitar. THE FINDINGS Scorers high in openness (original, creative, curious and complex thinkers) exhibited a lot of local movement (movement in a specific location). High scorers for conscientiousness (well organized, self-disciplined, thoughtfulness, good impulse control) exhibited global movement (extremities), head speed and hand distance. High scorers for extraversion (outgoing, social, energetic, excitability) exhibited all five movement components. High scorers for neuroticism (anxiety, irritability, moodiness) exhibited local movement only. Those who scored high for neuroticism exhibited jerky motion and accelerated motion. Also interesting to note, neuroticism was the only trait that had a negative effect on movement. More and more we are finding that movement reveals different aspects of personalities.
