Final answer:
The term for when someone imitates all movements done in front of them is mirroring, which is associated with observational learning and linked to the function of mirror neurons. (option 1)
Step-by-step explanation:
When someone imitates all movements done in front of them, the term used is mirroring. This concept is often discussed in psychology, particularly in the context of observational learning. Observational learning, as opposed to classical and operant conditioning which are forms of associative learning, involves learning by observing others and then imitating or modeling their actions or behaviors.
The individuals who are being imitated are known as models. This type of learning has been linked to a specific type of neuron known as a mirror neuron. Such neurons are thought to play a crucial role in allowing us to imitate the actions of others as part of our learning processes.
Hence, the answer is option 1
