Psychologist: In a study, children were observed in a room filled with various toys. When an adult was present in the room, the children were more likely to share toys with their siblings than with non-siblings. This suggests that children are more inclined to share with family members when they feel they are being observed by an authority figure.
The psychologist's argument would be most strengthened if it were true that, during the study, the children exhibited increased sharing behavior when:
A. the toys in the room were new to the children, rather than toys they had previously played with at home.
B. the observing adult was a parent of the siblings, rather than a stranger or non-relative adult.
C. the siblings were younger and appeared to need help understanding how to use the toys, compared to non-siblings who were adept at using the toys.
D. the room had more toys available than usual, making it easier for children to find and share multiple toys.
E. the adult explicitly encouraged the children to share, regardless of whether the other child was a sibling or a non-sibling.
This answer strengthens the psychologist's argument that children are more inclined to share with family members when observed by an authority figure by specifying that the authority figure is closely related to the children. This suggests that the presence of a familiar authority figure (like a parent), as opposed to a stranger, might have a significant impact on the children's choice to share specifically with siblings, reinforcing the observation's connection to familial authority.
A.
This choice does not directly affect the children's decision to share with siblings versus non-siblings when observed by an adult. It focuses on the novelty of toys, which is unrelated to the influence of an adult observer on familial sharing behavior.
C.
This choice introduces another variable (the age and competence of the children) that could influence sharing behavior, but it does not directly support the idea that observation by an adult specifically encourages sharing with siblings.
D.
This option focuses on the availability of toys rather than the influence of an adult's presence on sharing behavior. While more toys might make sharing easier, it doesn’t specifically strengthen the argument about sharing more with siblings under adult observation.
E.
This choice weakens the argument rather than strengthening it. If the adult encouraged sharing with all children equally, it suggests that the observed difference in sharing between siblings and non-siblings might not be influenced by the adult’s familial relationship but simply by general encouragement to share.
