In day-to-day language, emotion has a broad menaing encomasing all of the ways we assess and feel about the world and peope and thinsg in it: love, fear, joy, surprise. In psychology emotion refers to physiological effects such heart rate, whereas feeling refers to the interpretation of this in higher-order ways such as 'fear' or 'excitement'. In addition, mood refers to the longer term orientation, for exampel, if you are feeling particularly down, or particularly positive a about things. Crucially in many situations the physiological effect (emotion) preceeds the interpretation (feeling), and the latter deoends on your mood. For example, if someone burst a balloon your heart will instantly race, but whether this leads to a sense of fun, fear or anger depends on your {{mood} and the situation. In day-to-day speech both emotion and feeling are often called 'emotion'. The distinction is important, however, when creating intelligent user interfaces that seek to interpret or predict human emotional responses. It can also be useful when considering artificial emotion, with different ways to emulate the physiological side and the interpretation.
