Eyes
The point in the retina where the optic nerve leaves the eye, creating a lack of photoreceptors, is known as this.
What is the blind spot?
This fluid-filled, snail-shaped structure in the inner ear is essential for converting sound vibrations into neural signals that the brain can interpret.
What is the cochlea?
This is the only sense not processed first in the thalamus of the brain.
What is smell/olfaction?
This principle of perceptual organization states that objects that are close to one another tend to be grouped together.
What is proximity?
This phenomenon occurs when we fail to notice a change in our environment because our attention is focused elsewhere.
What is change blindness?
This part of the eye is responsible for controlling the amount of light that enters.
What is the pupil?
This part of the ear contains the three smallest bones in the human body, known as the malleus, incus, and stapes, which help transmit sound vibrations to the inner ear.
What is the middle ear?
This term refers to the minimum level of stimulus intensity needed for a stimulus to be detected.
What is absolute threshold?
This visual phenomenon refers to perceiving objects as unchanging despite changes in retinal image.
What is perceptual constancy?
This the name of the effect where people attend to mentions of their names or specific topics in loud or distracting environments.
What is the cocktail party effect?
These specialized neurons in the retina are responsible for color vision.
What are cone cells?
Damage to hair cells in this part of the ear can lead to sensorineural hearing loss.
What is the cochlea?
This sense controls balance and is primarily detected by the semicircular canals and structures in the brain.
What is vestibular sense?
This theory of color vision proposes that we perceive colors through the relative rates of response by three types of cone cells.
What is trichromatic theory?
This type of processing occurs when our perceptions start with an incoming stimulus and build up to a final representation in our minds.
What is bottom-up processing?
This part of the eye contains the highest concentration of cone cells and is critical for high acuity vision.
What is the fovea?
This theory suggests that different frequencies of sound stimulate different locations on the basilar membrane, explaining how we perceive pitch.
What is place theory?
This is a theory that explains how the brain regulates and modulates the perception of pain; allowing pain or blocking the signal
What is gate control theory?
This class of depth cues give the illusion of depth on flat or two-dimensional surfaces.
What are monocular depth cues?
This is a mental predisposition or readiness to perceive stimuli in a particular way based on previous experiences, expectations, beliefs, and context.
What is a perceptual set?
This part of the eye contains photoreceptor cells called rods and cones and is crucial for processing light and color.
What is the retina?
This theory of pitch perception posits that the frequency of the auditory nerve's impulses corresponds to the frequency of a tone, allowing us to detect pitch.
What is frequency theory?
This is the sense of one’s body movement. It allows the body to move in coordinated ways without having to look at the various parts of the body as it moves
What is kinesthesis?
This is the binocular depth cue where we see the merging of the retinal images by the brain
What is convergence?
This is a cognitive structure that serves as a framework for one’s knowledge about people, places, objects, and events.
What is a schema?
