Sensation and Perception
These specialized neurons respond to particular types of stimuli.
What are sensory receptors?
This wave property refers to the distance from one peak to the next.
What is wavelength?
The frequency of a sound wave determines our perception of this.
What is pitch?
This sense helps us maintain balance and body posture.
What is the vestibular sense?
This Gestalt principle explains why objects located close together appear to belong to the same group.
What is proximity?
This process occurs when sensory receptors detect stimuli from the environment.
What is sensation?
In light waves, amplitude influences our perception of this quality.
What is brightness or color intensity?
These three tiny bones of the middle ear are the malleus, incus, and stapes.
What are the ossicles?
This term refers to the perception of the body’s position.
What is proprioception?
According to this Gestalt principle, we tend to group things that look alike.
What is similarity?
During this process, sensory receptors convert stimulus energy into neural impulses.
What is transduction?
These photoreceptors work best in bright light and provide detailed color vision.
What are cones?
These sensory receptors inside the cochlea respond to movement of its fluid.
What are hair cells?
This term refers to the perception of the body’s movement through space.
What is kinesthesia?
This Gestalt principle causes us to perceive incomplete images as complete objects.
What is closure
This is the minimum amount of stimulus energy needed for detection 50% of the time.
What is absolute threshold?
This area of the retina contains many cones and provides sharp, detailed vision.
What is the fovea?
This sense, also called gustation, includes sweet, salty, sour, bitter, and umami.
What is taste?
These skin receptors respond to light pressure.
What are Merkel’s disks?
This cue allows us to perceive depth because each eye receives a slightly different view of the world.
What is binocular disparity?
This type of processing uses previous knowledge, experiences, and expectations to interpret sensations.
What is top-down processing?
Visual information from the right visual field travels to this hemisphere of the brain.
What is the left hemisphere?
This type of hearing loss results from a failure to transmit neural signals from the cochlea to the brain.
What is sensorineural hearing loss?
This type of pain results from damage to neurons in the peripheral or central nervous system.
What is neuropathic pain?
This phenomenon occurs when a person fails to notice a visible object because their attention is focused elsewhere.
What is inattentional blindness?
