The receptors located toward the center of the retina that are responsible for day and color vision
What are cones?
Minimum stimulation necessary to detect a sense 50% of the time.
What is absolute threshold?
The strength of the soundwave.
What is amplitude?
The system of sensing the position and movement of individual body parts.
What is kinesthesis?
The ability to focus ones attention on a single talker among a mixture of conversations and background noises.
What is cocktail-party effect?
Theory of color vision that explains complementary afterimages. Sensory receptors come in pairs.
What is opponent-process theory?
The perceptual process that works from big picture (general) to small details (specific). Our brains organize and interpret information and put it into context.
What is top-down processing?
Neural cells alternate firing so you can hear frequencies above 1000 per second.
What is volley theory?
The proper name for our sense of taste
What is gustatory system/gustation?
The lobe and cortex responsible for processing tactile sensory input
What is the parietal lobe; somatosensory cortex?
Visual signal that the objects are closer than the ones behind it.
What is interposition?
For people to perceive a difference, the stimuli must differ by a constant proportion/percentage.
What is Weber's Law?
Deafness caused by damage to the cochlea or the auditory nerve.
What is sensorineural deafness?
Receptor cells at the top of each nasal cavity.
What are olfactory receptor cells?
When senses become joined and one sort of sensation produces another.
What is synethesia?
After the opening number, Rachel's eyes are no longer bothered by the bright stage lights (what has occurred?)
What is sensory adaptation?
Using features on the object (details) itself to build a perception (big picture). No background knowledge or context. Just trying to process raw data coming in.
What is bottom-up processing?
The ear structure labeled B
What are the semicircular canals?
We hear different pitches because different sound waves trigger activity at different areas in the cochlea.
A mental predisposition to perceive one thing and not another and influence what you hear, taste, feel, and see.
What is perceptual set?
The path of a neural impulse through the retina (4 parts)
Rods/cones => Bipolar cells => Ganglion cells => Optic nerve
Facial blindness.
What is prosopagnosia?
The theory that says pitch perception depends on the rate that the entire basilar membrane vibrates
What is frequency theory?
The process of converting sensory input into signals that can be processed in the brain
What is transduction?
The theory that explains why biting your tongue while getting an injection blocks your experience of pain from the needle
What is gate-control theory?
