Parts of the Ear
After spinning around quickly, a person feels dizzy and loses their balance. The doctor explains that this is due to the fluid inside their ear, which helps detect rotational movements.
What are the semicircular canals?
A person experiences difficulty adjusting to changes in light intensity, and their doctor finds that the opening in their iris is either too wide or too narrow, preventing optimal light regulation.
What is the pupil?
A person is asked to detect the faintest sound in a noisy environment. This measurement is being used to find their threshold of hearing.
what is absolute threshold?
These individuals experience tastes more intensely than the average person, often describing flavors as stronger and more pronounced.
Who are supertasters?
This theory explains how we perceive pitch based on the frequency of the vibrations in the basilar membrane of the cochlea.
What is Frequency Theory?
After a person attends a loud concert, they notice that they have trouble hearing high-pitched sounds. A doctor explains that this is because sound vibrations are no longer being properly converted into neural signals.
What is the cochlea?
A person is having trouble focusing on nearby objects. The eye doctor suggests that the focusing of light as it enters the eye might be impaired in the transparent part at the front of the eye.
What is the cornea?
This law states that the just-noticeable difference between two stimuli is a constant proportion of the original stimulus.
What is Weber’s Law?
A person with difficulty distinguishing between red and green colors may have a type of color blindness.
What is red-green color blindness (dichromatism)?
In this scenario, a person perceives different pitches by the basilar membrane vibrating in different places in the cochlea, with higher frequencies causing vibrations closer to the base and lower frequencies causing vibrations near the apex.
What is Place Theory?
A person is diagnosed with hearing loss, and the doctor points out that the auditory nerve is damaged, preventing sound signals from being sent to the brain.
What is the auditory nerve?
After a bright light is shone into a person’s eye, their pupil constricts, reducing the amount of light entering the eye. The doctor explains that this is controlled by the colored part of the eye.
What is the iris?
A researcher is testing how well people can distinguish between two colors of light by varying the intensity. The test is measuring their ability to notice the smallest difference in color.
What is the just-noticeable difference?
A person is tested on their ability to see different colors, and the results show that their cones respond to blue, green, and red wavelengths of light.
What is the trichromatic theory (Young- Helmholtz)?
A person may feel more inclined to purchase a product if they have been exposed to related concepts or images beforehand, even if they don't consciously remember the exposure. This is an example of this.
What is Priming?
A person is experiencing hearing loss after being exposed to loud noise. The audiologist explains that the part of the ear that funnels sound into the auditory canal might be affecting their ability to hear clearly.
What is the pinna?
A person has difficulty focusing on objects at various distances, and the doctor says that their lens is not adjusting properly.
What is the lens?
After entering a room with a strong odor, a person will stop noticing the smell after a while. This phenomenon is explained by this process.
What is Sensory Adaptation?
After walking into a bakery, you instantly smell fresh bread baking. The sensory signal travels from your nose to your brain via this nerve, allowing you to identify the scent.
What is the olfactory nerve?
A person experiences a phenomenon where they can "taste" sounds and "hear" colors. This is a rare condition where the senses are mixed.
What is synesthesia?
A person is having trouble hearing sounds because the vibrations from the eardrum aren't being transmitted properly through the three small bones in the middle ear. The doctor explains that these bones amplify the vibrations before they reach the inner ear.
What are the hammer, anvil, and stirrup?
A person notices that they can see objects clearly in their peripheral vision but have difficulty seeing objects directly in front of them. The issue is in the small area of the retina responsible for sharp central vision.
What is the fovea?
When one sense influences another, such as when the taste of food is affected by its smell, this term describes the interaction between senses.
What is Sensory Interaction?
This type of taste is often described as savory or meaty and is recognized by its association with foods like soy sauce, Parmesan, and broths.
This type of hearing loss is caused by damage to the inner ear or auditory nerve, often due to aging or prolonged exposure to loud noises.
What is Sensorineural Deafness?
