Which behavior is likely to be motivated by a desire to gain attention?

Making silly noises is likely motivated by a desire to gain attention because this behavior is typically designed to elicit a response from others. Children and even adults often engage in attention-seeking behaviors to garner laughs, interactions, or reactions from peers and adults. The intention behind making silly noises is commonly to be noticed or to create a social bond through laughter or curiosity.

In contrast, the other behaviors listed may not primarily seek attention. Running out of the room could indicate a need for escape or avoidance, rather than a desire for engagement. Staring at a ceiling fan appears to be a passive activity and does not inherently solicit attention from others. Hiding in a closet may signify withdrawal or a desire for solitude rather than an attempt to attract attention. Each behavior conveys different underlying motivations, but making silly noises directly aligns with the intention of eliciting attention and interaction from others.
