Movement Functioning and Balance

  • Overview of Movement Functioning

    • Movement and balance are crucial for everyday functioning.
    • Examples of movements such as taking a bottle of water require coordination.
    • The action of bringing water to your lips involves:
    • Numerous muscles (hundreds engaged).
    • Utilization of various unique sensors.

  • Proprioceptors

    • Definition: Proprioceptors are specialized sensors that provide information about body position and motion.
    • Location: Found in muscles, joints, and tendons.
    • Kinesthesis:
    • Definition: Kinesthesis is the sense that allows us to be aware of our body's position and movement.

  • Vestibular Sense

    • Function: Works alongside kinesthesis to maintain balance during movement.
    • Key Components:
    • Receptors in the semicircular canals: Fluid-filled structures that help detect motion.
    • Cerebellum:
      • Role: Processes information to monitor balance.
    • Vestibular sacs: Crystal-filled components contribute to balance monitoring.

  • Sensory Interaction

    • Definition: Sensory interaction is the principle that one sense can influence another.
    • Example: The smell of food can affect the taste perception.

Embodied Cognition

  • Definition of Embodied Cognition

    • Embodied cognition refers to the influence of bodily sensations and gestures on cognitive preferences and judgments.

  • Complexity of Sensory Systems

    • Each sensory system is complex and interacts with others; no single sense acts alone.
    • Flavor Perception:
    • Interaction between smell and taste enhances flavor complexity.
    • Other factors:
      • Touch and Texture: Contribute to eating and drinking experiences.
      • Vision: Plays a vital role, adding another dimension to kinesthetic sense.

  • Interaction between Hearing and Vision

    • Example: The McGurk effect illustrates how what we see can influence auditory perception.

  • Sensation and Perception

    • Sensation and perception work together to shape our experiences of the world.
    • Phenomenon of Embodied Cognition:
    • Sensory processing circuits interact with cognitive processing circuits, influencing how we think about our current sensations.
