Research Summary
My research is concerned with understanding the fundamental mechanisms of intelligence in animals, with particular emphasis placed on learning. With Geoffrey Hall, from the University of York, I have developed an original theory concerning the role that attention plays in learning. According to this theory, animals will pay attention to a task while they learn about it, but once it has been mastered, they will direct their attention elsewhere. I have also developed a theory about the information animals acquire when a pattern of stimulation is repeatedly used to signal an important event, such as food. The pattern of stimulation is assumed to be remembered as a sort of mental snapshot, based on all the information that was present immediately prior to the occurrence of food.
Most of the foregoing research is based on experiments conducted in test chambers that provide a well controlled environment for studying the fundamental mechanisms of animal intelligence. Other research of mine is exploring the extent to which the principles derived from this research extends to more naturalistic settings, such as navigating through familiar territory to locate a hidden goal. Thus far, the principles appear to apply reasonably well to both types of environment.
Teaching Summary
I offer a series of lectures on animal intelligence for the Biological Psychology module in Year 1. In Year 2, I present a practical on perception. In Year 3, I contribute to the Animal Learning and Cognition module.
