Main Results:

  • Significant disagreement exists regarding the precise behaviors that classify individuals as left- or right-handed.
  • The motivations behind choosing one hand over the other for specific tasks are not fully understood or agreed upon.

Conclusions:

  • Further research is needed to establish standardized methods for assessing handedness.
  • Understanding the etiology of hand preference requires addressing both behavioral definition and motivational factors.
