Research Interest
In Assoc Prof Christopoulos' lab, they use advanced neurobehavioral methods to examine the following questions:
- Methods to record and evaluate human psychocognitive status (especially fatigue).
- Human learning and decision making (risk and trust), with a focus on cognitive flexibility and computerised training of working adults.
- Environmental (Urban) Neuroscience: focusing on the effects of indoor and outdoor spaces and their architectural characteristics on human performance, health and happiness.
A recent grant examines the effect of soundscaping and sounds on human cognition about beauty and how they affect consumption of cosmetics, and how culture and cultural symbols (statues, images, buildings) affect emotions as well aesthetic and other judgments.
Methods: besides traditional methods, they are interested in Virtual Reality and Wearables and how they can be used to assess human behavior.
Besides pure academic research, they also collaborate with industry (such as cosmetics companies) to understand how consumers choose and use cosmetics and other products, using implicit and explicit methods.
His research aims to uncover, explain, predict and improve human decision making in dynamic and complex environments. A central topic is on neurobehavioral and social aspects of individual learning and computerised cognitive training. Recently, they are also interested in understanding the relationship between human behaviour and the built environment especially in Mega-Cities.
A current focus is on the effects of sound and soundscaping on human cognition. Methodologically they employ the two research traditions of decision theory and cognitive neuroscience. These include behavioural methods derived from psychology; computational methods stemming from game theory, learning theory and microeconomics; and biological measurements such as human neuroimaging using functional Magnetic Resonance Imaging (fMRI) and eye-tracking.
