Study Notes
Perception and Sensory Processes
- Perception involves interpreting sensory information and consciously experiencing it.
- Inattentional blindness refers to failing to notice visible stimuli due to lack of attention.
Characteristics of Sensory Waves
- Amplitude is defined as the height of a wave and is related to the intensity of sensory experiences.
- The visible spectrum is the range of light wavelengths that humans can perceive.
Neural Pathways and Sensory Information
- The optic nerve transmits visual information from the retina to the brain.
- Hearing involves transduction, where sound waves are converted into neural messages.
Hearing and Balance
- Vertigo is characterized by a spinning sensation that affects equilibrium.
- The vestibular sense assists in maintaining balance and body posture.
Adaptation and Perception
- Sensory adaptation occurs when prolonged exposure to a stimulus leads to decreased sensitivity; for example, not hearing crickets after starting a conversation.
Sense Examples
- Audition is exemplified by hearing a song on the radio.
- Gustation is illustrated by the experience of tasting freshly caught salmon.
Eye Structure and Function
- The iris is the part of the eye responsible for eye color.
- Higher amplitudes correlate with louder sounds, while lower amplitudes relate to softer sounds.
Chemical Senses
- Olfaction (smell) and gustation (taste) are termed chemical senses because they respond to molecules from food and air.
- Additional taste groupings include umami and perception of fat content.
Deaf Culture and Hearing
- Contrary to some beliefs, deaf culture does not universally advocate for cochlear implants for children.
- Cochlear implants work by receiving sound and directly stimulating the auditory nerve.
Visual Processing
- The optic chiasm is crucial for visual processing, directing visual information from the right visual field to the left brain and vice versa.
- In low light conditions, the pupil dilates to permit more light into the eye.
Sound Frequency Perception
- High-frequency sound waves are perceived as high-pitched, while low-frequency sound waves are perceived as low-pitched.
Smell as a Sensory Experience
- Olfaction is showcased through the ability to smell cookies baking in the oven.
