A non-permanent change to mental state while still conscious; examples include daydreaming, hypnosis, or meditation
Variable ratio schedule
A partial reinforcement schedule where reinforcement is granted randomly and unpredictably, such as a teacher occasionally giving stickers for good grades on tests when the mood strikes
Stimulant
A psychoactive drug that blocks the reabsorption of substances like seratonin or dopamine, leading to an increase in energy; examples include caffeine and cocaine.
Frequency Theory of Hearing
A theory of hearing that asserts that the neurons of cilia will go off to match the frequency of the sound that enters the ear.
Classical conditioning
A type of behavioral training that uses two simultaneous stimuli, such as the sound of a bell and the smell of food, to produce an involuntary reaction, such as salivating
Fixed ratio schedule
A type of partial reinforcement schedule that uses reinforcement only when a certain threshold of behavior repetition is reached, such as giving a dog a treat after it sits on command 3 times
