Review Questions

• How does parental investment affect sibling rivalry among children?
  • Parental investment plays a significant role in shaping sibling rivalry since children often compete for their parents' attention and resources.

In contrast, equitable investment may help reduce conflicts by fostering cooperation and reducing competition among siblings.

This competition can manifest in aggressive behaviors or emotional outbursts when siblings feel threatened by each other. Understanding this dynamic can help parents address conflicts effectively by ensuring fair distribution of resources and promoting positive interactions between siblings.
• Evaluate how sibling rivalry might influence social behavior later in life.
  • Sibling rivalry can have lasting impacts on social behavior as individuals navigate relationships outside their family unit. Those who experienced intense rivalries may develop coping mechanisms like assertiveness or competitiveness in social settings. Alternatively, they might also learn valuable skills like negotiation and empathy if rivalries were managed constructively. Overall, early experiences of sibling rivalry shape interpersonal dynamics in adulthood, influencing how individuals relate to peers and authority figures.
