What is the Cocktail Party Effect?
To focus one's listening attention on a single talker among many conversations and background noises
What is the Opponent-Process Theory of Vision?

What is the coiled, fluid-filled tube of inner ear called?
Cochlea
What is a binocular cue for depth perception?
A cue that requires both eyes to perceive depth
What is an Agonist?
Fit into receptors and mimic neurotransmitters to increase their effects
Reflective practice in which people attend to current experiences in a nonjudgmental and accepting manner
What is Change Blindness?
Failure to notice obvious change
What is Accommodation?
The Lens changing shape to focus on near and far objects in our vision.
What is Sensorineural Hearing Loss?
Results from damage to the cochlea’s hair cells. Can be helped by cochlear implants
What perceptual rule is an illusion of movement that arises when stationary objects, such as light bulbs or loading screens, are placed side by side and illuminated rapidly one after another?

What is the Frecequency Theory of Pitch?
We hear different pitches because The cochlea vibrates at the same speed as the sound, so the brain reads how fast it’s vibrating to know the pitch.
What perceptual rule states that when individual elements have alike attributes like a color or size, humans often perceive them as belonging together?
Similarity
Alcohol falls under which of 4 the categories of drugs?
Depressant
What is the Unconscious State?
Information stored here is usually not known or available under most circumstances
What is Bottom-Up Processing?
Processing that starts with our sensory receptors and works its way up to our brain.
What part of the eye controls the size of the Pupil?
Iris
What is the Volley Theory of Pitch?
Neural cells work together, like a relay race, alternating when they fire in rapid succession, controlling pitch.
What is Figure-Ground?
The human brain automatically separates a visual scene into a main focus object (the figure) and its surroundings (the ground)
Morphine and Heroin fall under which of the 4 categories of drugs?
Opiates
What is the Consciousness?
Our awareness of ourselves and our environment.
What is Top-Down Processing?
Processing that starts with our brain, context, and experiences first, and then work its way down to our sensory receptors.
