Handedness studies explore the preference individuals show for using one hand over the other, typically categorized as right-handed or left-handed. Researchers investigate how this preference affects various aspects of life, including motor skills, cognitive abilities, and even personality traits. These studies often involve observing tasks like writing, throwing, or using tools to determine hand dominance. Understanding handedness can also shed light on brain function, as the two hemispheres of the brain control different sides of the body. For instance, left-handed individuals may have different brain organization compared to right-handed people, influencing how they process language and perform tasks.
