Study Notes
Kinesthetic Sense
- Kinesthetic sense, or kinesthesis, is the sense that tells you where the parts of your body are with respect to one another.
- It monitors the positions of the various parts of the body.
- Receptors in the joints transduce mechanical energy into neural activity, providing information about both the rate of change and the angle of the bones.
Vestibular Sense
- Vestibular sense is the sense of equilibrium or body balance.
- It gives us information about body position, movement, and acceleration.
- The sensory organs for the vestibular sense are located in the inner ear, specifically in the semi circular canals above the cochlea.
- The receptors are filled with the fluid endolymph and have nerve fibers.
Auditory Sense
- Sound vibrations hit the cochlea, which is lined with hair cells.
- Hair cells move and trigger the release of neurotransmitters.
- Electrical signals are sent by the auditory nerve to the brain.
- Conduction deafness occurs when there is poor transfer of sounds from the tympanic membrane to the inner ear and can be compensated with an amplifier (hearing aid).
- Nerve deafness is caused by damage to hair cells or auditory nerve and cannot be compensated with hearing aids.
Somesthesis (Skin)
- Somesthesis refers to sensations of the skin, including touch, pressure, pain, cold, warmth, itching, and vibration.
- Nerve receptor cells are located at various depths throughout the skin and are distributed unevenly throughout the body.
- Physical properties that stimulate somesthesis include temperature, pressure, and chemicals.
Pain
- Pain is a sensation that tells the body that something has gone wrong.
- Sensory Conflict Theory states that motion sickness occurs because vestibular system sensations do not match sensations from the eyes and body.
Perception
- Perception is the process of giving meaning to the environment around us.
- Characteristics of perception include the need for a stimulus, immediate experience, active mental processing, organization of stimuli, and selectivity.
- Factors that influence perception include selective screening, perceptual set, the Pollyanna principle, and perceptual grouping.
- Perceptual organization is the process of grouping stimuli into recognizable patterns, also known as the "Gestalt Process".

Description
Explore the concepts of Sensory Conflict Theory and Perception, which explain the occurrence of motion sickness and the cognitive process of interpreting stimuli. Learn about how discrepancies between vestibular system sensations and visual/body sensations can lead to motion sickness, and how perception plays a crucial role in understanding our environment.
