ACTIVITY LEVEL: Refers to overall output of energy or behavior. It has two intercorrelated aspects: (1) vigor, i.e., intensity/amplitude of behavior; (2) tempo, i.e., speed of activities.
SOCIABILITY: The tendency to prefer being with others rather than being alone. Involves the desire for other people's attention, to share activities and for the responsiveness and stimulation that are part of social interaction. To be sociable is to intrinsically value the interaction process.
