Applied behavior analysis is a scientific discipline concerned with applying techniques based upon the principles of learning to change behavior of social significance.
Answer:
Syntax.
Explanation:
What Syntax studies is the principles and processes of sentences in a particular language, including the word order. In this case, the sentences "The dog chased the cat" and "The cat chased the dog" mean different things because of the word order: The dog chased the cat means that the dog was running behind the cat, after him. If the cat chased the dog, the opposite. In this simple example we notice the importance of syntax and the word order in a sentence. It's not the same if we say "The man was helped by the medic" rather than "The medic was helped by the man" even if it shares the exact same words.
