What type of repair might a partner use when an argument threatens to become too emotionally intense?

The most relevant type of repair in situations where an argument is at risk of becoming too emotionally intense is the use of guarding. This refers to a partner's strategy to protect the emotional safety within the conversation. It often involves pausing, stepping back, or calling for a break in the discussion to allow both partners time to regain composure and reflect on their feelings.

Guarding helps to de-escalate the situation, maintaining a support system within the relationship and ensuring that both partners can express themselves without fear of hurtful outcomes. This strategy aligns with Gottman’s emphasis on emotional regulation and the importance of staying connected and safe during conflict.

The other choices, while relevant in various contexts, do not serve the primary function of addressing the immediate emotional intensity of an argument. Compromise and agreement focus more on resolution than on managing emotional safety, and self-disclosure might add vulnerability to the argument but doesn't directly address the emotional temperature of the discussion.
