Key Concepts

Embodied Cognition

This concept suggests that our cognitive processes, including how we form and understand concepts, are deeply rooted in our bodily interactions with the world. Rather than being abstract and detached from sensory input, knowledge and meaning are acquired through experiences that involve our sensory and motor systems.

Functional Neuroimaging

Functional neuroimaging techniques, such as fMRI and PET scans, provide evidence that when individuals process certain concepts—especially those related to actions or perceptions—there is activation in specific areas of the brain that are also involved in corresponding sensory or motor tasks. This imaging evidence establishes a link between conceptual understanding and the neural circuits of the sensorimotor system.

Sensorimotor Simulation

This idea posits that, when we think about a concept, our brain often reactivates patterns of neural activity similar to those experienced during the original perception or action. In other words, understanding a concept may involve mentally simulating the sensory or motor experiences associated with it, thereby reinforcing the connection between cognition and bodily states.

Distributed Semantic Representations

This concept refers to the notion that semantic knowledge is not stored in a single, isolated module but is instead distributed across various areas of the cortex, including those associated with sensory and motor functions. This distributed nature of conceptual representations implies that understanding is inherently linked to the sensorimotor experiences encoded in these different brain areas.
