Interoception is the process of sensing the internal states of your own body. This can include sensing your emotions (disgust, happiness, fear, etc.) but also sensing more basic physical states, such as hunger, nausea, pain, temperature, and feeling your heart beat and breathing changing. Interoceptive abilities relate to our ability to understand our own emotions, process reward, make decisions, and look after our physical health (e.g. noticing when we are unwell). This topic investigates the varied ability in those with and without autism to recognise a range of internal states within the body.
