Study Notes
Sensory Systems
- Otoliths are tiny, motion-sensitive crystals that help detect body position and balance.
- Retina is the part of the eye that converts visual images into electrical impulses for the brain.
Skin Senses
- Skin senses include pressure, touch, temperature, and pain.
Ear Function
- The Basilar Membrane in the ear contains hair cells that send auditory information to the brain.
- Semicircular Canals aid in maintaining balance.
Chemical Communication
- Pheromones are chemicals that signal sexual availability among individuals.
Perception Principles
- Gestalt laws of organization describe how we perceive patterns as whole forms rather than individual components.
- Perception is the process of interpreting and integrating sensory stimuli.
Stimuli and Detection
- The absolute threshold is the minimum intensity of a stimulus required for detection.
- A stimulus is the source that triggers sound processing in the auditory system.
Taste Qualities
- There are four basic taste qualities recognized: bitter, salty, sour, and sweet.
Vision Mechanisms
- Rods are light-sensitive receptor cells in the retina responsible for vision in low-light conditions.
- Cones are involved in color perception and function best in bright light.
- The Place theory of hearing explains how different frequencies activate specific areas of the basilar membrane.
- The Opponent Process theory describes how color vision receptors are organized in pairs.
Ear Components
- The Eardrum vibrates in response to sound waves, playing a crucial role in hearing.
Color Vision
- The Trichromatic theory of color vision posits three types of cones in the retina contribute to color perception.
Visual Perception
- The visual spectrum shows the difference in light sensitivity between humans and bees, highlighting that bees can see ultraviolet light which is invisible to humans.
Sensation vs Perception
- Sensation refers to the physical response elicited by sensory organ activation.
Weber's Law Application
- Weber’s Law applies to various senses: touch, smell, taste, hearing, and vision.
Olfactory System
- Olfactory cells in the nose respond to odor molecules, playing a key role in smell perception.
