The key components of social interactions like negotiation are perception, cognition, and emotion. Perception involves how people make sense of their environment and can be distorted through biases like stereotyping. Cognition refers to how people frame issues and are subject to biases such as anchoring. Emotion impacts negotiation - positive emotions tend to facilitate integrative outcomes while negative emotions usually hinder negotiations. Managing perceptions, frames, biases, and emotions is important for effective negotiation.
