What is the dependent variable?
A type or cell responsible for communication in the nervous system
What is a neuron?
The broad band of nerve fibers joining the two hemispheres of the brain.
What is the corpus callosum?
The study of behavior and mental processes
What is the definition of psychology?

What is a negative and weak relationship?
The term used to describe a chemical that increases a neurotransmitter's effect
What is an agonist?

What is the amygdala?
A perspective taken by a researcher who studies whether it is possible to drive safely while listening to a podcast
What is the cognitive perspective?
Trevor surveyed college students about the number of hours they watched TV in the previous week. He found that most people he talked to watched about 5 - 10 hours per week, but a very small group of students watched around 35 hours per week. To avoid reporting a deceptively high average, he decided to report two measures of central tendency.
What is the mean and the mode?
The best way to describe what this correlation coefficient represents: -0.82
A strong and negative relationship.
The neuron implicated in both Parkinson's disease and schizophrenia
What is dopamine?
The lobe of the brain associated with processing visual information.
What is the occipital lobe?
A perspective taken by a researcher who studies the impact of culture on likelihood of being punctual

What is a control group?
It facilitates the transmission of signals along the axon of a neuron
What is myelin sheath?
The strip of cortex in each frontal lobe, allow us move parts of body
The motor cortex
