Sensation & Perception
The minimum stimulus energy needed to detect a particular stimulus half of the time
Absolute Threshold
These are the three primary colors of LIGHT. The retina produces different colors from these three color receptors
Blue, Red, and Green
This disorder is characterized by persistent problems in either falling or staying asleep
Insomnia
Darwin's principle of traits getting passed down from generations based on chances of survival and reproduction
Natural Selection
In the visible color spectrum, this color has the longest wavelength
Information processing that constructs perceptions from the sensory input by drawing on our experiences and expectations. I.e. Doctor's note
Top-Down Processing
Retinal receptor cells that detect fine detail, and give color sensations. We primarily use this in a well-lit room
Cones
This stage of sleep is characterized by periodic sleep spindles (bursts of brain activity)
NREM-2
These two groups of people are ideally best for studying the differences of behavior between genetics and environment
Identical Twins & Adopted Individuals
Conversion of one form of energy to another
Transduction
We inherently organize stimuli according to coherent groups such as proximity, similarity, and continuation. These are _______ principles
Gestalt
This is the nerve that carries neural impulses from the eye to the brain
Optic Nerve
This stage of sleep is characterized by a rise in heart rate, faster breathing, eyes darting back and forth. It is also when dreams occur.
REM
This is a complex molecule containing the genetic information that makes up the chromosome.

DNA (Deoxyribonucleic Acid)
If Prof. Melara were to divide his classroom into two groups based on where the students would be sitting, which of Gestalt's laws would he be using?
Proximity
We constantly wear our watches/shoes and thus, become less aware or unaware of them. This is the concept that best explains why there starts to become diminished sensitivity to these stimuli.
Sensory Adaptation
A coiled, bony-filled tube in the inner ear that picks up the sound vibrations from the middle ear and triggers nerve impulses
Cochlea
This disorder is characterized by the stopping of breathing over a short duration during sleep. It is also associated with obesity.
Sleep Apnea
Belyaev conducted an experiment to study the domestication of animals through natural selection over a short period of time. What specie of animal did he use?
Fox
One might have a stimulus show right in front of their face, but yet fail to notice it because their attention was directed elsewhere at the time. This is an example of what concept?
Selective Inattention
Perceiving objects as unchanging even as illumination and retinal images change. I.e. Seeing two balls with different backgrounds, one the size as a brick, the other the size of a tunnel
Perceptual Constancy
A ring of muscle tissue that controls the size of the pupil opening
Iris
Multiple Answers:
This is a theory on why we dream
To reflect cognitive development.
To make sense of neural static.
To develop and preserve neural pathways.
To file away memories.
To satisfy our own wishes (Freud)
Study of how your behaviors and environment can cause changes that affect the way your genes work
Epigenetics
This experiment conducted on infants observed how this age group perceives depth
