Study Notes
Sensation
- It's the process of receiving, converting, and transmitting sensory information about the outside world.
Sensory Systems
- Vision: Visual receptors located on the retina, rods are for night vision and cones for color vision.
- Hearing: Audition occurs via sound waves, vibrations in air pressure caused by objects. Receptors in the inner ear (cochlea) convert sound energy to neural impulses.
- Smell (Olfaction): Receptors located at the top of the nasal cavity.
- Taste (Gustation): Taste buds on the tongue. Four basic tastes: sweet, salty, sour, and bitter.
- Vestibular Sense (Balance): Receptors are in the inner ear.
- Kinethesis (Body Movement): Receptors in muscles, joints, and tendons.
- Touch: Skin detects pressure, temperature, and pain.
Processing
- Sensory Reduction: Filtering and analyzing sensations before sending messages to the brain.
- Transduction: Converting receptor energy into neural impulses.
- Adaptation: Decreased sensory response to continuous stimuli.
Psychophysics
- The study of the relationship between the physical properties of stimuli and a person's experience.
- Absolute Threshold: The minimum amount of energy we can detect.
- Difference Threshold (JND): The smallest change in a stimulus we can detect.
Perception
- A constructive process where we go beyond presented stimuli to create meaning.
