Cue In Action: When Dave was presenting his research on butterflies, his gestures were erratic and out of tune with what he was saying. He seemed scatterbrained, moving back and forth across the stage, his arms pointing quickly to his whiteboard and then scratching his face and neck. He was difficult, even annoying to follow.
Meaning and/or Motivation: Jerky movements comes across as hysteric, frustrated, and breeds a lack of respect in others and is generally unflattering. It says nonverbally that a person lacks precise control over their bodies which people assume transfers to erratic thoughts and a scattered mind. People with jerky movements are seen as untrustworthy and often as having hyperactivity disorder.
Usually sporadic behaviour is not due to any actual negative traits and is mostly due to a high affect, meaning people simply have lots of excess energy and don’t like being in one place for extended periods of time. Other times, jerky movements are linked to excitement and enthusiasm for a topic.
Cue Cluster: Watch for erratic movements of the eyes, touching the face, neck, nose, ears, rubbing the eyes, pacing back and forth, pointing, smoothing clothing, patting, rubbing the hands, hands in pockets and so forth.
