Final answer:
Children who are seldom mentioned on self-reports of social preferences are usually socially neutral or have low social engagement.
Step-by-step explanation:
Children who are seldom mentioned, either positively or negatively, on self-reports of social preferences are usually those who are socially neutral or have a low level of social engagement. These children may not actively seek attention or actively avoid confrontation. They tend to blend in with the group and may not express strong preferences or dislikes for certain individuals. For example, in a classroom setting, these children may not be singled out as being popular or unpopular. Instead, they may be seen as more neutral and may not stand out in terms of social preferences.
