Fear is an emotional response to impending danger, that is tied to anxiety. Behavioral theorists, like Watson and Ekman, have both suggested that fear, along with a few other basic emotions (e.g., joy and anger), is a trait innate to most higher functioning organisms. Fear is a survival mechanism, and usually occurs in response to a specific negative stimulus.
