Study Notes
Types of Processing
- Top-down processing involves interpreting sensations influenced by knowledge, experiences, and thoughts.
Sensation vs. Perception
- Perception is the interpretation and conscious experience of sensory information.
- Sensation is the detection of sensory information by receptors.
Inattentional Blindness
- Demonstrated when participants focus on specific colors, often failing to notice unexpected stimuli, like a red cross.
Olfaction Example
- Smelling cookies in the oven exemplifies the sense of olfaction.
Kinesthesia
- Refers to the ability to sense muscle movement and position, important for activities like biking.
Subliminal Message
- A subliminal message, such as "Drink Cola," can be imperceptible if it is below the absolute threshold.
Photoreceptors in Color Perception
- Cones are the photoreceptors most useful for perceiving colors, especially in well-lit environments.
Vestibular Sense
- The vestibular sense helps maintain balance during activities, such as standing on one leg.
Taste Groupings
- In addition to the basic tastes (sweet, salty, sour, bitter), humans can also taste umami and fat content.
Cochlear Implant Function
- A cochlear implant enables hearing by receiving sound and directly stimulating the auditory nerve to send signals to the brain.
