Experience is the first person effects or influence of an event or subject gained through involvement in or exposure to it. The term does not imply that useful or long term learning, or the acquisition of skills necessarily takes place as a consequence of the experience, though the two are often associated, and experience is often used as a proxy for competence. A large amount of learning of knowledge and skills is associated with experience, and experience is a necessary, though not always sufficient component of the learning of physical skills. Terms in philosophy such as "empirical knowledge" or "a posteriori knowledge" are used to refer to knowledge based on experience. A person with considerable experience in a specific field can gain a reputation as an expert. The concept of experience generally refers to know-how or procedural knowledge, rather than propositional knowledge: on-the-job training rather than book-learning.
