🔍 Big Idea: Oxytocin isn't just the "love hormone." It has a dark side too!

• Oxytocin & Bonding: Helps us bond with our group, leading to increased trust and closeness.
• Surprise Side Effects: Can also play a role in prejudice, discrimination, and conflict!

🌍 Real-world example: Ever felt closer to your soccer team after a winning game but had an irrational disliking for the rival team? That's oxytocin working!

• Purpose: Examine oxytocin's role in defense-motivated non-cooperation.
• Design: Double-blind, independent measures design.
• Sample: 102 males.
• Procedure: Participants took either oxytocin or a placebo nasal spray. They were divided into groups and competed against another group in a modified "Prisoner’s Dilemma" game.

🎮 Understanding the "Prisoner's Dilemma" Game with Real-world Example: Imagine you and your best friend are accused of a prank. If you both stay silent (cooperate), you'll get minimal punishment. But if one speaks (competes) and the other stays silent, the one who speaks gets rewarded, and the silent one gets the maximum punishment. If both speak (compete), both get moderate punishment. Do you trust your friend enough to stay silent?

•  Best Friends Forever: Both cooperate. Everyone gains equally. (7 points each)
•  Trust Issues: Both compete. Everyone gets less than in A. (6 points each)
•  Betrayal Alert!: I cooperate, but they compete. They gain the most (8 points), but I get a reduced amount (5 points), and my team suffers the most (1 point each).
•  Reverse Betrayal: The opposite of C.

🍰 Tasty Analogy: Consider a cake slice. Outcome A is like sharing the biggest slice equally. In Outcome B, everyone gets a medium slice. Outcome C & D? Someone's hogging the biggest slice, and the other gets crumbs!
