Human experience is fundamentally shaped by emotions, which have an impact on our perceptions, behaviours, and interactions. Emotions have typically been divided into two major categories: basic emotions and complex emotions. Simple emotions, which include core affective states like happiness, anger, fear, sadness, and disgust, are thought of as fundamental and universal. Complex emotions, on the other hand, cover a broad spectrum of nuanced and merged emotional experiences that result from the fusion of simple emotions or appear in reaction to sophisticated thought processes. In order to shed insight on their specific qualities and underlying mechanisms, this research article explores the differences and parallels between simple and complicated emotions. We can better comprehend the emotional environment and how it affects human behaviour and wellbeing by examining this duality.
