First impressions refer to the initial thoughts and feelings that people form about someone or something upon first encounter. These impressions can be influenced by various factors, including appearance, body language, and tone of voice. Research shows that first impressions are often formed within seconds and can be difficult to change later. The significance of first impressions extends to various contexts, such as job interviews, social interactions, and public speaking. In professional settings, a positive first impression can lead to better opportunities, while a negative one may hinder relationships. Understanding the impact of first impressions can help individuals present themselves more effectively in different situations.
