Nutrition and Cognition research

My research background is in biological psychology and neuroscience, and I am interested in biological factors and mechanisms which affect human cognition and behaviour across the lifespan. Much of my research has focused on the effects of glucose administration and glucose regulatory mechanisms on human cognition.

Sugar rush or sugar crash?: A meta-analysis of carbohydrate effects on mood

The effect of carbohydrate (CHO) consumption on mood is at the center of a long-standing debate, with researchers reporting both mood improvements and decrements following CHO ingestion. As global consumption of sugar-sweetened products has sharply increased in recent years, … Continue Reading about Sugar rush or sugar crash?: A meta-analysis of carbohydrate effects on mood

Last in, first out: brain economy in times of limited resources

It has been argued that cognitive abilities that developed last ontogenetically are likely the first to become impaired when cognitive and/or physiological resources are compromised. In phylogeny as in ontogeny, the prefrontal cortex is a late developing region of the cortex. … Continue Reading about Last in, first out: brain economy in times of limited resources

A temporary deficiency in self-control: can heightened motivation overcome this effect?

Self-control is important for everyday life and involves behavioral regulation. Self-control requires effort, and when completing two successive self-control tasks, there is typically a temporary drop in performance in the second task. High self-reported motivation and being made … Continue Reading about A temporary deficiency in self-control: can heightened motivation overcome this effect?
