mood process A mood process is a mental process that involves affect (is valenced), and gives rise to a number of behavioural dispositions, but unlike an emotion has no object. Moods are usually longer-lived than emotion processes, but there are exceptions. Moods are more difficult to individuate into types than emotions. We may speak of a good mood, a bad mood, or suchlike. We may also speak of being in an angry mood or other moods which take their identity from emotions. These often accompany a heightened disposition to undergo the emotion they are named for. affective process
