The tendency to use either the left or the right side of the body; handedness is called:

• A. Laterality
• B. Ambidexterity
• C. Handedness
• D. Lateral Preference

Answer: (A)

Laterality is the tendency to use one side of the body over the other. It covers not just which hand you favor, but broader biases like eye, foot, or ear preference as well. Handedness is a specific form of laterality—the preference for one hand in most tasks. Ambidexterity means being equally skilled with both hands, so it isn’t describing a bias toward one side. Lateral preference is another way to say favoring one side, but laterality is the standard, more general term. So the best choice is laterality because it captures the overall left–right bias rather than a specific hand preference or the ability to use both sides equally.
