Answer:
anxiety and novelty seeking
Step-by-step explanation:
Anxiety will create a general discomfort that can happened in many instances (maybe in social situations, when learning something that they're not comfortable with , etc.) In some cases, they responded to this anxious behavior by seeking novelty as new source of excitement to replace their anxiety.
Among children, novelty seeking (excitement seeking) probably carried out by running around, pulling their friends' hair, screaming, etc.
But if this type of behavior is carried out until adolescence, the novelty seeking that they seek to address their anxiety could developed into things such as vandalism and substance abuse.
