Animals, including humans, readily learn links between events that occur close together in time and space. The classic example from animal learning comes from Pavlov’s demonstration that dogs that were fed immediately after hearing a bell began to salivate in advance of the food when the bell was rung. This can be described in terms of the dogs learning an association between the mental representation of the bell, and the mental representation of food, such that hearing the bell activates the representation of food (and that in turn drives the relevant responses). One major strand of my research examines the mechanisms by which associations are formed and influence behaviour in both humans and other animals. This has included an exploration of some, seemingly unlikely, phenomena where associative learning may play a crucial role: for example in learning how to distinguish similar faces, how animals deal with problems of causation, or how people learn their likes and dislikes.
A second major strand of my research involves the assessment of hedonic responses in rodents. Animal models are of critical importance in investigating the underlying biological contributions to many human disorders such as depression or schizophrenia. To fully understand these animal models we require ways to assess how animals feel, as well as how they think. As it happens, a detailed examination of the way in which rodents drink is particularly informative with respect to how much they like what they are drinking (e.g. rats tend to produce few, but rather long, bouts of licks when they like the solution they are drinking but the length of the bouts decreases, while the number of bouts can increase, with less palatable solutions). Research in my lab is currently using this technique to investigate how animals learn to like and dislike particular foods and also how such hedonic processes are affected in animals models of human disorders, in particular schizophrenia, depression and dementia.

Addysgu
I am the chair of the undergraduate exam boards.
Levels 1 and 2: I teach introductory lectures on statistics and biological psychology (PS1015 and PS2017). I also run cognitive practicals and give tutorials on social, perception, cognition and abnormal/clinical psychology (supporting PS2007, PS2003, PS2009, PS2018).
Level 3: I supervise projects on a variety of topics including face perception and the learning and expression of food preferences.
Thesis examination
I have examined both MSc and PhD theses both internally and externally (eg for the University of Sydney and the University of NSW).
