Study Notes
Visual Sensation
- Eyes are the primary organ for vision
- Light enters the eye, focusing on the retina
- Photoreceptor cells (rods and cones) convert light into signals
- Signals travel through the optic nerve to the brain
- Different pathways process visual information for different tasks like color, depth, and motion
- The process of transduction involves converting physical light signals into action potentials in the nervous system.
Visual Perception
- Visual cues like texture gradients, linear perspective, and relative size help determine depth perception
- Depth cues contribute to the perception of distance and 3D space
- Heuristics (mental shortcuts) influence visual processing, potentially leading to misinterpretations
- Vision interacts with other senses like hearing – e.g., the visual system can influence how sounds localization is perceived
Auditory Sensation
- Ears are the primary organs for hearing;
- Sound waves travel through the ear canal to the eardrum
- The middle ear amplifies the vibrations
- Inner ear transforms vibrations into electrical signals
- Signals travel through auditory nerves to the brain
- Transduction converts sound waves into neural signals.
Auditory Perception
- Interactions between auditory systems and other senses, like vision or touch shape our auditory experience
- For example, visual cues can influence our interpretation of sounds
Smell & Taste
- Smell and taste use receptors to interpret molecules
- Olfactory receptors (nose) and taste receptors (tongue) detect chemical signals
- The system of nerves transmits information from receptors to the brain
- Sense of smell and taste are linked and influence each other
Touch
- Touch uses mechanoreceptors (skin receptors)
- Different types of touch receptors register different types of stimulation (pressure, vibration, pain, temperature)
- Sensory receptors in skin transmit to nervous system
Pain
- Pain signals originate from nociceptors in the skin and internal organs
- The gate-control theory proposes pain signals can be modulated by other sensations
- Pain is influenced by psychological and emotional factors
