Action semantics: A unifying conceptual framework for the selective use of multimodal and modality-specific object...

Area of Science:

• Cognitive Neuroscience
• Human Cognition
• Tool Use Research

Background:

• Human object use extends physical capabilities, involving flexible and complex actions.
• Action semantics, encompassing declarative and procedural knowledge, enable meaningful object interaction.
• Existing research on object use involves behavioral, developmental, neuropsychological, and neuroimaging studies.

Purpose of the Study:

• To review current research on human object use.
• To propose a novel conceptual framework for action semantics.
• To integrate findings on object affordances, goals-means relationships, and the organization of action semantics.

Main Methods:

• Literature review of behavioral, developmental, neuropsychological, and neuroimaging studies.
• Analysis of common themes and discussions across different research domains.
• Development of a novel conceptual framework for action semantics.

Main Results:

• Research domains share discussions on object affordances, goal-means relationships, and the organization of action semantics.
• Action semantics involve multimodal object representations and modality-specific subsystems (manipulation, functional, sensory/proprioceptive).
• Action semantics are hierarchically organized and context-dependent.

Conclusions:

• A novel framework integrating multimodal representations and modality-specific subsystems explains object use.
• Hierarchical organization and context-dependent activation of action semantics are proposed.
• This framework offers an integrative perspective to guide future interdisciplinary research on object use.
