The textbook outlines three main modes of interaction: domination, competition, and cooperation. Explain each, addressing efficiency, characteristic emotion, and level of inequality in the interaction.

Domination is a mode of interaction where one party exerts power and control over another. This can lead to efficient decision-making and action, as the dominant party's authority is unquestioned. The characteristic emotion in domination is often fear or submission, as the dominated party may feel powerless and oppressed. This mode of interaction typically results in a high level of inequality, as the dominant party holds all the power and resources.

Competition is a mode of interaction where parties strive to outperform each other in order to achieve a goal or gain a reward. This can lead to efficiency in terms of driving individuals or groups to improve and innovate. The characteristic emotion in competition is often a mix of excitement and anxiety, as participants are motivated to succeed but also feel pressure to outdo others. This mode of interaction can result in varying levels of inequality, as some may emerge as winners while others may experience loss.

Cooperation is a mode of interaction where parties work together towards a common goal, often through sharing resources and responsibilities. This can lead to efficiency through the pooling of skills and resources. The characteristic emotion in cooperation is often trust and camaraderie, as participants work towards a shared purpose. This mode of interaction typically results in a lower level of inequality, as parties work together to achieve mutual benefit.
