Hindsight 20/20: The future of laterality research

Area of Science:

• Neuroscience
• Evolutionary Psychology
• Developmental Psychology

Background:

• Recent advances in laterality research have broadened theoretical frameworks and investigative methods.
• Comparative studies suggest ancient functional and anatomical brain biases are conserved in modern humans.
• The developmental trajectory and cognitive contributions of these biases remain incompletely understood.

Purpose of the Study:

• To emphasize the necessity of an evolutionary framework for understanding human brain development and behavior.
• To integrate motor-sensory behavior within the broader context of a developing cognitive system.

Main Methods:

• Review of recent literature in laterality research.
• Comparative analysis of functional and anatomical brain biases across species and developmental stages.
• Theoretical framing integrating evolutionary principles with developmental psychology.

Main Results:

• Confirmation of the persistence of ancient brain biases in contemporary human populations.
• Identification of gaps in knowledge regarding the developmental unfolding of these biases.
• Highlighting the importance of an evolutionary perspective for future research.

Conclusions:

• Human brain biases have deep evolutionary roots and are observable in modern populations.
• Further research should adopt an evolutionary framework to elucidate the developmental and cognitive roles of laterality.
• Motor-sensory behavior should be considered a fundamental component of cognitive development.
