Emotion

Emotion refers to short-lasting affective states which occur in response to significant life events.

Emotions are complex - they involve physiology, cognition, behaviour, and social communications, as well as feelings. The main reason for the occurrence of different emotions is that they each serve a motivational function.

What is emotion?
Emotion is not easily defined. It involves the complex psychophysiological experience of an individual's state of mind as interacting with biochemical and environmental influences. In humans, emotion fundamentally involves "physiological arousal, expressive behaviours, and conscious experience".

More simply, it's how we feel about things. Many of the chapters which follow will delve into conceptualising emotion and particular aspects of emotion - both what affects emotion and how emotion affects behaviour and thinking.

 * "synchronised brain-based systems that coordinate feeling, bodily response, purpose, and expression so to ready the individual to adapt successfully to life circumstances" (Reeve, 2018, p. 289)
 * "short-lived psychological-physiological phenomena that represent efficient modes of adaptation to changing environmental demands" (Levenson, 1994, p. 123)
