Leverhulme Lecture 2/3: The Science of Self-Control

In this lecture I outline some of the main perspectives on self-control and its loss stemming from recent work in psychology. I focus in particular on the puzzle arising from the role of glucose in successful self-control. Glucose ingestion seems to boost self-control but there is good evidence that it doesn’t do this by providing fuel for the relevant mechanisms. I suggest that glucose functions as a cue of resource availability rather than fuel.
