The Basics
This term refers to the later stages of processing that allow us to recognize, store, and interpret sensory information.
What is perception?
This muscle controls how much light enters the eye.
What is the iris?
The difference in sound level reaching each ear helps determine sound location.
What is interaural level difference?
This brain area contains a full somatotopic map of the body.
What is the somatosensory cortex?
Foods high in protein are most strongly associated with this basic taste.
What is umami?
The minimum stimulus intensity that can be detected 50% of the time is known as this threshold.
What is the absolute threshold?
This area of the retina is responsible for high-acuity vision.
What is the fovea?
This ear structure contains hair cells arranged in a tonotopic map.
What is the cochlea?
This threshold measures how far apart two points must be to be felt as distinct.
What is the two-point threshold?
Odors are detected more strongly in enclosed spaces primarily due to this factor.
What is higher odorant concentration?
Grouping soccer players by jersey color illustrates this Gestalt principle.
What is similarity?
This cue for depth perception relies on information from the muscles that control eye movements.
What are oculomotor cues?
Abnormal bone growth in the middle ear causing hearing loss is known as this condition.
What is otosclerosis?
Compared to the thigh, the big toe has greater ________.
This group typically has the most sensitive sense of smell.
Who are 25-year-old nonsmokers?
This is the physical object itself that gives rise to sensory stimulation, such as a motorcycle on the street.
What is the distal stimulus?
This principle explains why we perceive objects moving together as belonging together.
What is common motion?
Motion sickness occurs when this system conflicts with the visual system.
What is the vestibular system?
These mechanoreceptors are involved in the pleasantness of gentle touch.
What are C-tactile mechanoreceptors?
Difficulty judging whether odors are pleasant or unpleasant suggests damage to this brain region.
What is the orbitofrontal cortex?
Accommodation and convergence provide depth information based on changes in the lens and this.
What is the position of the eyes?
Information about depth derived from changes in the shape of the lens comes from this process.
What is accommodation?
Damage to hair cells from excessive noise exposure leads to this type of hearing loss.
What is sensorineural hearing loss?
Larger receptive fields result in this outcome when testing tactile sensitivity.
What is poorer spatial resolution?
A green-colored lemon drink tasting sweeter demonstrates this influence on flavor perception.
What is visual perception?
