What is the main concept of top-down processing?
What is the main concept of top-down processing?
- It uses existing knowledge and expectations to influence perceptions. (correct)
- It involves the processing of sensory information from the environment to form perceptions.
- It relies solely on sensory receptors to form perceptions.
- It is a bottom-up process that starts with individual sensory elements.
How do odor molecules (odorants) interact with receptor sites in smell perception?
How do odor molecules (odorants) interact with receptor sites in smell perception?
- They bind permanently to the receptor sites, causing a permanent change in perception.
- They block the receptor sites, leading to a temporary inability to detect odors.
- They trigger action potentials in the receptor sites by locking into certain sites. (correct)
- They repel the receptor sites, causing a temporary loss of smell perception.
Which area of the brain is linked to emotion and memory in the context of smell perception?
Which area of the brain is linked to emotion and memory in the context of smell perception?
- Cerebellum
- Amygdala and Hippocampus (correct)
- Hypothalamus
- Medulla oblongata
