What is Pavlovian conditioning?
Pavlovian conditioning, or classical conditioning, is the psychological process by which two stimuli are linked together to produce a conditioned response. The psychologist Pavlov discovered this when he found that with training, ringing a bell (stimulus) made dogs salivate (response), because it was paired with receiving food (stimulus).

How does positive transfer help you learn English?
Positive transfer is the process by which knowledge of your own language helps you to learn another language. One of the ways this happens is through cognates. For example. if you are a native Spanish-speaker, you probably know the word "continente." When learning English, this will be an easy word to learn, because it is essentially the same - continent. These are cognates. because they are almost the same word in both languages. Therefore, knowledge of the Spanish word would help you with learning the English one.

How are signals transmitted in the brain?
Information passes through the brain via neurons. Neurons are composed of dendrites, which receive signals; a cell body, which processes those signals; an axon, which transmits action potentials (electric signals); and an axon terminal, which releases neurotransmitters (chemical signals), all of which are necessary for the transmission of information. Information passes from neuron to neuron via the synapse, which is where the neurotransmitters of the presynaptic neuron attach to receptors on the dendrites of the postsynaptic neuron.
