Goal-directed behaviour is a key element of adaptive behaviour and is integral to functions such as decision making. It is thought to be heavily influenced by impulsivity and compulsivity, both of which vary across the lifespan. This project will examine how real-world, ecologically valid measures of impulsivity, compulsivity and goal-directed behaviour vary across three key developmental periods: late adolescence, middle adulthood, and older adulthood. The project will obtain psychological [online app], physiological [eye tracking], and neural [fMRI] measures of impulsivity, compulsivity and goal-directed behaviour and use computational modelling approaches to establish how these change across the lifespan.
